FLO Cycling - 2014 Year in Review

It's that time again.  I love reviewing the year.  2014 was a great year for us.  We had a number of operational changes.  We went from our products being shipped from our house, to a dirt floor warehouse and finally to a fulfillment center.  Time was becoming a big issue for the two of us and unloading the shipping to a fulfillment company gave us about four months of our lives back.  I am going to follow the format from last year so things can be compared.  Also, you can check out our "2012 Year in Review" and "2013 Year in Review"  for comparison.  

This article will be broken down into three sections.  

Section 1 - Sales Data, Shipping Info, and Other Cool Stuff
Section 2 - Social Media and Website Growth
Section 3 - Our Thoughts for 2015

Section 1 - Sales Data, Shipping Info and Other Cool Stuff

Number of Wheels Sold
At the end of last year we said if we sold anywhere near 5,000 wheels we would be thrilled.  In 2012, we sold 1,500, 2013 we sold 3,356 and in 2014 we sold 4,989.  Yes, we are thrilled!

Number of Bike for a Kid Donations
We continued our partnership with the Ironman Foundation this year.  We were able to donate 357 bikes and helmets to less fortunate kids this year.  Our total is now 758.  We are excited for 2014 and have formed an additional partnership with More Than Sport.  If all goes as planned we hope to pass 1,000 bikes and helmets donated in 2015.  

Number of Orders Placed at FLO Cycling
Even though Chris and I had become pretty efficient and processing orders, the amount of time we were spending shipping wheels was taking away from running the business.  An average order took 10 days to organize and each day we spent 12-15 hours processing.  With eight orders in 2014 that was about 1,000 hours each.  Considering the average number of hours worked in one year is 2,000, shipping was a major undertaking.  We decided to hire an order fulfillment company, and in June of 2014 we handed our shipping over to eFulfillment Services.  With 2,818 wheel orders received this year it was great to still have the time to run our business.  Thank you eFulfillment Services.

Number of Countries and Territories Where FLO Wheels have Shipped
I get pretty excited when we ship a wheel to a new country or territory.  This year we were able to add five.  

Other Cool Stuff
Here are a few interesting facts about the year.  

Top 5 Countries by Number of Order Placed
1.  USA - 74.06%
2.  Canada - 6.53%
3.  UK - 4.76%
4.  Australia - 3.97%
5.  Sweden - 1.67% - Sweden bumped out Denmark this year and is new to the list.  

Top Three Wheels According to Sales
1.  Front FLO 60
2.  Rear FLO 90
3.  Front FLO 30

Favorite Sticker Color: Stealth Black
Max Number of Gigabytes of RAM our Servers used at one time: 150
Cumulative Number of Emails Sent and Received: 250,000
Number of Sushi Rolls Consumed During Shipping Weeks: We may have mercury poisoning. =/
Number of Cliff Jumping Sessions in Kona: 3
Number of Dogs Added to the FLO Cycling Team: 2 - Quoddy the Nova Scotia Duck Tolling Retriever (left), and Ruby the German Shorthaired Pointer (right).

Section 2 - Social Media and Website Growth

As an online business that is run from our houses, social media is very important to us.  Here is how our social media grew in 2014 along with a few fun facts.

Facebook Likes
By the end of 2014 we had 6,170 likers on Facebook.  That's 41% growth from 2013.  

Last year Andy Murray's Winning Wimbledon video took the cake for the most shared post on Facebook.  This year AMC's Minions Holiday message was the winner.  They are catchy little buggers.

Twitter Followers
Our Twitter followers passed 2,000 this year with over 40% growth. 

She's the Queen of Twitter.  Katy Perry takes the prize again this year for the most Twitter followers.  If she keeps winning I am going to run out of pictures of her on a bike.  =]

YouTube Subscribers and Video Views
I have to admit that our YouTube growth surprises me.  This year our number of YouTube subscribers surpassed our Twitter followers.  We are also getting close to 500,000 video views with 456,707.

It's the year of dogs.  This years top YouTube video was a dog dressed up like a giant spider running around scaring people.  Handsome fella! 

FLO Cycling Website Visitors and Number of Page Views
Tracking the number of visitors to your site for an online business is pretty important.  We've seen steady growth this year.  The cool thing to me is that our page views per visitor is also growing.  Below are the number of website visitors, website page views, and blog page views we saw in 2012-2014. 

Can anyone guess who the king of the internet is with the most page views?  Yep, it's still Google.  

Countries to Visit our Website
Depending on who you ask, there are either 195 or 196 countries in the world.  Funny enough, Taiwan - where our wheels are made - is the disputed country.  At the end of 2014 we've officially had visitors from 179 countries.  There's 16, or 17 to go.

App Session Views
A new addition this year is the number of app session our iPhone app has received.  An app session means that someone opens the app to use it.  We saw 41% growth this year with 98,218 sessions.

FLO Cycling Newsletter Subscribers
We are happy to see that people like our newsletter.  Writing blog content is a big part of what we do.  When people want us to share it with them, that's an added bonus.  With just under 20,000 newsletter subscribers, it appears these engineers aren't too bad at writing.  =]

When I read that our email campaign company mailchimp.com sent 70,000,000,000 - yes billion - emails last year, I wondered if that was the ceiling.  How many more can you really send?  Well, apparently you can send 100,500,000,000 in a year. 

Stickers Applied
Putting stickers on wheels was my job for the last two years.  This year I passed the torch to our fulfillment company.  Before I finished I had surpassed 30,000 stickers in my sticker career.  Here's to another 30,000 more.  

Section 3 - Our Thoughts for 2015

At the end of last year we mentioned that we would be working on a new product.  We did.  While it's taken longer to develop then we expected, we are currently waiting for partial prototypes at this time.  We hope to have an update for everyone soon.  This new product means that 2015 will be a development year.  We plan to discuss the development like we did with our wheel design back in 2010 and 2011.  

We are also starting to study tires.  At the end of 2014 we started to build an on bike data logger to tell us things we've thought about for years.  We will be covering this process on our blog as well.  

Take care,

FLO Cycling - IdeaMensch Interview

I was just interviewed by IdeaMensch, a website known for interviewing entrepreneurs.  This interview was originally published at ideamensch.com.  You can see the interview on their website here, http://ideamensch.com/chris-thornham/ OR read the interview below.
I hope you enjoy it!


Chris Thornham is a co-founder of FLO Cycling, which engineers aerodynamic cycling wheels. The company uses computational fluid dynamics software to develop its wheels and verifies its results in a wind tunnel.
Born and raised in Dartmouth, Nova Scotia, Canada, Chris grew up with an interest in engineering and sports. In high school, with the help of his twin brother, Jon, he placed third in the engineering division at the National Science Fair by designing an apparatus that cast a fly-fishing rod by itself.
Chris went on to study mechanical engineering at the University of New Brunswick and worked as a ski instructor and technical representative for a ski company. During breaks, he and Jon would travel to other cities, such as Las Vegas, Los Angeles, and Vancouver, to earn money for tuition.
When Chris graduated in 2006, he moved to Las Vegas to take a job as a mechanical engineer. To no one’s surprise, Jon received the same job. After starting their new jobs, it didn’t take long for the brothers to start working on their own business. In 2008, they launched a charitable organization called Painting With Purpose. It was a learning experience, but the business ultimately failed due to a lack of marketing knowledge.
Shortly after Painting With Purpose closed its doors, Chris and Jon studied marketing before starting their next venture. In 2010, they founded FLO Cycling. Two years later, they hosted their debut sale, selling 750 wheels to consumers in 28 countries in a single hour. Today, not even three years later, the company has sold 10,000 wheels to customers in 51 countries.
Aside from working at FLO Cycling, Chris enjoys learning, triathlon training, skiing, hiking with his dog, and spending time with family.

Where did the idea for FLO Cycling come from?

Growing up, Jon and I were athletic. We competed nationally as black belts in taekwondo, were downhill ski racers and instructors, and tried pretty much any other sport you can think of. After graduating from university, we started working 40+ hours per week as mechanical engineers. I kept going to the gym to stay in shape, but after a few months, I wanted to compete again. I was drawn to triathlons.
In triathlons, you swim, bike, and run in the same event. The bikes in triathlons are very technical, and I was immediately drawn to their design. While trying to purchase a bike, I learned quickly that they’re prohibitively expensive. Of all the components on a race bike, wheels are one of the most expensive items. The best wheels were, on average, $2,000 to $3,000 per set.
I showed Jon the price of these products, and he was as surprised as I was. I asked him if he thought we could design a similar product for a better price, and he thought we could. After nearly two years of design, factory sourcing, and planning our distribution strategy, FLO Cycling was born, and we were selling comparable wheels for one-half to one-third of the price of the competition.

What does your typical day look like, and how do you make it productive?

As a two-man business, Jon and I have to stay on track to get things done. The mornings typically start with going through email, our social media accounts, and forums. That’s typically followed by a walk with our dogs, when we talk about the business.
After that, we focus on a bigger task for the day. That ranges from product design to website design to marketing to customer service. That email/big task cycle typically repeats itself in the afternoon and sometimes after dinner. Somewhere in there, I typically fit in one to two hours of swimming, biking, or running.

How do you bring ideas to life?

As cliché as this may sound, we just do it. When we were younger, Jon and I used to talk about how cool it would be to own or work for a company where you could create cool products. We believe FLO Cycling is one of those companies. We’ve learned that there will always be roadblocks, but if you put your head down and continue looking for ways to make things happen, almost anything is possible.

What’s one trend that really excites you?

I love how technology is allowing people to create businesses from their living rooms or garages. With the software and easily accessible knowledge available today, there’s not much standing in the way of you and your wildest entrepreneurial dreams.

What is one habit of yours that makes you more productive as an entrepreneur?

Making a list or schedule of things to do and sticking to it. I used to react to everything the minute it came to me. This used to be possible when FLO Cycling was smaller, but now it’s not. You get so much more done when you focus on one thing at a time.

What was the worst job you ever had, and what did you learn from it?

I once worked for an egotistical micromanager. On top of always being wrong, there was a total lack of trust and respect for employees, and it killed morale. In a short period of time, there was a nearly 100 percent turnover of staff because people either quit or were terminated for ridiculous or made-up reasons.
That job pretty much taught me everything you shouldn’t do when dealing with people. When you trust and empower the right people, the sky is the limit.

If you were to start again, what would you do differently?

FLO Cycling was our second business. In all honesty, it was our do-over. Our first business failed, but it was an incredible learning experience. I think that allowed us to get a lot right with FLO Cycling. That said, if we were going to start another business, I think it would focus more on technology, not a physical product.

As an entrepreneur, what is the one thing you do over and over and recommend everyone else do?

Always move forward. If you stop moving forward, you get nowhere. After our first business failed, Jon and I spent a period of time trying to figure out what we were going to do next. We had several business ideas in mind, and we stalled for months, not starting either of them. I sat down with a successful entrepreneur and asked him if he ever got to a point where he simply couldn’t figure out what to do. His answer changed me.
“Never stop moving forward,” he said. “At any given time, you have a certain amount of information. With that information, you have to make the best decision you can and take a step forward.”
Jon and I followed his advice, and FLO Cycling was the next step.

What is one strategy that has helped you grow your business?

Don’t ever sell. In this day and age, people don’t want to be told to buy something. Instead, if you help answer their questions while they’re in the buying cycle, provide them with informative content, and treat them with respect, they’ll want to buy from you. You won’t even have to ask.

What is one failure you had as an entrepreneur, and how did you overcome it?

We started our first business without knowing anything about marketing. We thought our idea was so great that everyone would just buy our product. We forgot to think about what the customer wanted. As a result, the business failed. Before starting FLO Cycling, Jon and I took a period of time to learn about marketing. We didn’t want to start another business until we felt like we were prepared.

What is one business idea that you’re willing to give away to our readers?

I think pediatric home health for new mothers would work well. Getting out of the house with a newborn is a chore. Add another kid or two into the mix, and it’s even harder.

Tell us something about you that very few people know.

Jon and I acted for a brief period of time in university. In fact, a month or so before graduating, Jon and I were up for supporting lead roles in a Disney film. Our agent said it was down to Jon and me and one other set of twins. We said to ourselves: “If we get the role, we’ll go act. If not, we’ll go be engineers.” I think you know what happened.

What software and web services do you use? What do you love about them?

• Wunderlist makes organizing my to-do list easy, especially when coupled with the book “Zen To Done” by Leo Babauta.
• Coda  makes web development easier to manage.
• Rackspace makes managing scalable web servers easy.
• iOS SDK allows us to create iPhone apps.
• QuickBooks keeps accounting and bookkeeping manageable.
• Autodesk Inventor Professional allows us to create 3D models of our mechanical designs.
• STAR-CCM+ allows us to test aerodynamics at a fraction of the cost of real-world wind tunnels with highly accurate results.
• iWork makes creating and updating spreadsheets and documents easy.

What is the one book that you recommend our community should read and why?

The New Rules of Marketing and PR” by David Meerman Scott changed the way I look at marketing altogether.

What people have influenced your thinking and might be of interest to others?

David Meerman Scott, Jonah Berger, Patrick Lencioni, and Seth Godin.

FLO Cycling - Studying Tires Part 4, Relative Velocity

This week we have new parts.  I just received a new wind speed sensor.  If you wondering why I’d guess you are not alone.  While a Garmin will give us great data on rider speed it will not give us any information on relative velocity.  For example, if you are riding 20mph in to a 5mph head wind, your relative velocity is 25mph.  If you want to learn more about this you can check out our blog on Relative Velocity.  

This is important to know because it gives us an accurate wind speed for the recorded yaw angle.  With out it we are left comparing rider speed and yaw angle which, leaves a lot of unknowns. 

I recently went for a ride to test out the sensor.  Here is a quick video of the test.  


When I returned home I logged the data to see what was reported.  While my speed in the truck was pretty consistent, - minus the stops - you can see a number of variations in the wind speed.  

More testing is needed once the wind direction sensor shows up.  The latest update told me it was delayed but should hopefully be shipping this week or next.  

There are lots of interesting things coming up.  Stay tuned.  

Take care,

FLO Cycling - Studying Tires Part 3, How to Mount The Logger to the Bike

Last week I mentioned I was going to be busy in my garage making a mount for the data logger and sensors.  Well, I have been.  Here is what I have so far.  

The Basic Construction
I thought about what to build this with and after looking at aluminum, pvc, plastic, etc., I settled with good old wood.  Below is a shot of the mount drying after a few coats of paint.  I figured I’d try and make it look a little bit cool =]. 

To secure the mount to the bike I made a custom skewer that holds support arms.  The mount also rest on the top of my stem.  Since the mount only touches my skewer and stem it turns with the wheel.  This is what I wanted.  

Next Steps
I am anxiously awaiting the wind direction and speed sensors.  Once I have them I will mount everything.  If I don’t get a few comments and looks when I start riding around with this thing I’ll be highly surprised.  

Take care,

FLO Cycling - Studying Tires Part 2, Elevation Data

I’ve learned a lot since I posted “Studying Tires Part 1, Logging Data”.  I mentioned that I believed there was either a shift in the barometric pressure or that the absence of temperature and humidity were the reason for the shift in my driveway's elevation.  Today I have the results.  

A 12 Hour Backyard Plot
The graph below shows the barometric pressure over a 12 hour period.  I placed the logger in my backyard out of the sun to try and minimize and temperature variation. 

To make things easier to see I calculated the elevation for each barometric pressure reading.  The graph below shows the elevation of my backyard over the 12 hour period. 

I was quite surprised that there was a shift of almost 80 ft over the day.  It made the 22ft shift from the other day look pretty good.  The last time I checked the seismic activity in Las Vegas, it pretty low, so this got me thinking =].  

Barometric Pressure Records
I figured there had to be  a history of barometric pressures.  A few minutes in Google and I found a website that records the barometric pressure at major airports for a one week period and displays a graph.  When I compared my 12 hour log with McCarran International Airport - the airport in Las Vegas, where I live - my graph matched theres.  Here is a screen shot of the last seven days at the McCarran International Airport. 

This graph shows a shift in elevation of over 700 ft.  That's a massive difference.  

The Meteorologist
I needed a bit of help.  A good friend from university is a special type of energy trader.  He's one of the smartest guys I know.  Luckily for me, he hired a meteorologist to work on his team.  I reached out to my friend and the meteorologist and I ended up exchanging a few emails.  

During our discussion, he mentioned that it’s easy to see a shift in elevation of 60 ft.  A source he referenced mentioned that this shift is commonly up to 150ft.  This is still a lot better then the 700 ft I saw in Las Vegas, but still not great.  Even if you correct with temperature and humidity, you are still likely to see a 15 ft variance.  

What Know
The meteorologist recommend a combination of things I could try in an attempt to get more accurate elevation data.  He brought up the idea of using GPS, barometric pressure, temperature, humidity and hi-res topographic maps.  I like the idea but ultimately it may be a bit overkill for what I am doing.  Regardless, I will have to find a way to get an elevation that is accurate enough for my research.  

Next Up

Next week I should have an update on mounting the logger and sensors to my bike.  It’s time to get handy in the garage.  

Take care,

FLO Cycling - Studying Tires Part 1, Logging Data

For a while now, I've wanted to study the aerodynamic performance of tires on the road.  We done a bit of work in a wind tunnel, which is great, but it's not the real world.  In order to get the job done we needed a way to log data on the road.  Quite some time ago I started developing a logger on my own by programming a microcontroller and building sensors.  While I got pretty far, there were a number of things that weren't where they needed to be.  The biggest concern was accuracy.  The picture below is of the logger I built.

Microcontroller that I developed to read yaw angles, rider speed and wind speed.

Once I realized accuracy would be a problem I put things on the back burner for a while.  Last year during Interbike I sat down with Ryan Cooper from Best Bike Split and we talked about his work with the Trek Factory Racing Team.  He mentioned that math models were now able to predict accurate yaw angles of the riders, rider speed, elevation and a number of other things.  We also discussed the logger I had been developing and Ryan mentioned he would be interested to check his results with the results I was able to measure on the road.  That conversation got the ball rolling again and I went on a search for a logging system that would get me the accuracy I needed.  

Weather Stations are Great Loggers
After doing quite a bit of research I found that some of the best data loggers were weather stations.  They have the ability to sit in remote locations (battery powered), can collect large amounts of data over time (onboard memory storage), and collect multiple data points (versatility).  This all seemed like a good fit... I just needed to figure out how to mount it on the front of a bike!  

Onset's Hobo Micro Station
Luckily I found a system that worked for me.  I found a company called Onset that had a micro weather station that took four inputs and would mount well on my bike.  I ordered the micro station and five sensors.  
1.  Temperature Sensor (Altitude related measurements)
2.  Humidity Sensor (Altitude related measurements)
3.  Barometric Pressure Sensor (Altitude related measurements)
4.  Wind Direction Sensor (Yaw angle measurements)
5.  Wind Speed Sensor (Relative velocity measurements)

A few days ago, the micro station, temperature sensor and barometric pressure sensor arrived.  The wind speed sensor, humidity sensor, and wind direction sensor (on special order from Germany) are still on the way, but I was able to test the parts I did have.

With an initial set up, I was able to test the micro station's logging capability, the software package and the sensors, I mounted the micro station in the back of my truck and went for a drive up to Lee Canyon outside of Las Vegas.  

Micro Station mounted in my truck and a dog who's ready for a walk =]

The micro station was recording temperature and barometric pressure every second for just under four hours.  The flat line in barometric pressure displays a time when my trucked was parked while I was walking my dog.  Remember, as elevation increases, barometric pressure decreases.  The black line in the graph below shows the barometric pressure.  The blue line is the temperature.  There are a few jumps which relate to the sensor being in and out of the sunlight.

Calculating Elevation
The reason I got the barometric pressure sensor was to get accurate elevation data.  If you use the barometric formula - which there are a number of variations of - you can solve for altitude.  The barometric formula I used was the one below.  I believe I will have to modify this to incorporate temperature and humidity but that will be another day.

I needed to solve for height since I had the current barometric pressure so I rearranged the equation to the one below.  I dusted of the math skills on this one.  =].

With the new formula, I was able to calculate the elevation for each barometric pressure I recorded.  The results are graphed below.  The hardest part was putting the above equation in a Excel!  Here is what I found.  

To be honest I am pretty impressed with the data logger.  For the most part the elevations are spot on but the data did leave me with a few questions.  For starters, I noticed that the the elevation of my driveway - my starting and stopping point - were different.  I am no meteorologist, but my guess is that there was a shift in the barometric pressure over the four hours I was gone, or that not including temperature and humidity values in the equation was the problem.  Today I am logging data for 12 hours in my driveway to see if my theory on barometric pressure shift is correct.

That's it for today.  I will report back soon with the results of the 12 hour log in my driveway.  Hopefully by then I'll have a few more parts to test out.

Take care,

FLO Cycling - Tire Pressure and Temperature

Have you ever wondered what happens to your tire pressure when you ride through different temperatures?  How much does it change?  Should you pump your tires up inside or outside?  These are all things I recently started thinking about.  There are a few rules of thumb but I wanted to know why.  If you've had some of these same questions, or I've sparked your interest, I hope you enjoy the article below. 

How a Tire's Air Temperature Changes
It's important to know that there are two ways for a tires air temperature to change.  

1.  Ambient Air Temperature Change: If you pump your tires up inside your house where the air temperature is 72 degrees, and then move the wheels outside where the air temperature is 30 degrees, the temperature of the air inside the tires will eventually drop to 30 degrees as long as there are no mechanical interferences.

2.  Mechanical Change:  The three most common ways that a tires air temperature will change mechanically is from the suns radiation, from friction when the tire deforms during riding and from brake heat.  When the sun's rays hit a tire, it naturally increases the temperature of the tire and therefore the air inside the tire.  When you ride a bike the tire deforms near the contact patch.  The deformation causes friction and increases the temperature of the tire and therefore the air inside the tire.  Finally, when you brake, the friction of the pads and the rim creates heat that transfers to the air in the tire.

The Quick Rule of Thumb
If you read about tire pressure changes due to temperature changes, you will find that people say for every 10 degrees Fahrenheit, tire pressure will change approximately 2%.  That means if you start at 70 degrees Fahrenheit and increase the temperature to 80 degrees Fahrenheit, you will increase the tire pressure 2%.  Likewise, if you start at 70 degrees Fahrenheit and lower the temperature 10 degrees to 60 degrees Fahrenheit, you will lower the psi by 2%.

Proving that Tire Pressure Changes Approximately 2%
To prove this we need to discuss the Ideal Gas Law and do a bit of math.  

The Ideal Gas Law states the following.  

The units for the variables above are as follows.

Note:  To make things simple I will use degrees Fahrenheit and and psi in the discussion.  The math below will show all of the conversions if you want to see how we move between the different units.

Setting a Base Line
I am going to assume that we start with 100 psi at 70 degrees Fahrenheit.  Knowing this I can calculate the tire volume we will use for each future calculation.  Since we know the amount of gas will not change, we can assume that n = 1 and remove it from the Ideal Gas Law equation.  

Now that we have the initial air volume we can calculate the change in tire pressure for every 10 degrees Fahrenheit.  I will show one example below for an increase in ten degrees to 80 degrees Fahrenheit and then provide tables with multiple values.  Note:  Remember that these changes are for the first cause of tire temperature change, a change in the ambient air temperature.  

The difference is 1.888 psi or approximately 2% which is what the rule of thumb says.  The table below shows a number of different psi values when starting at 100 psi and 70 degrees Fahrenheit.  

To show that the 2% rule works at a different psi I also started with 50 psi at 70 degrees Fahrenheit.  You can see the table below.

Tire Pressure Recommendations and "Cold Tire Pressure"
When you read a recommended tire pressure from a manufacturer, what does this mean?  The tire pressure recommendations are "cold inflation pressures".  Cold tire pressure means that the tire has not been ridden and has been sitting for a while.  A car before the sun breaks in the morning that has been sitting overnight is a good example of cold tire pressure.  If you plan to ride on a winters day but store your bike inside your house you may experience a drop in tire pressure when you go outside.  It is true that the mechanical friction will raise the tire pressure and eliminate some of the drop.  Ultimately, the temperature effect is not nearly as dramatic as many might think.

So What Does all of this Mean?
Ultimately, I don't think that you really have to worry about tire pressure and temperature changes.  This is especially true if the ambient temperature where you pump your tires up is close to the ambient temperature where you are riding.  

If however, you are going to experience an extreme drop in temperature you may want to leave your bike and pump outside for a while before you pump your tires up or add a few psi for the upcoming change.  The opposite is true if you plan to raise the temperature to an extreme after you start your ride.  I've ridden at 110 degrees Fahrenheit after leaving a house that was 70 degrees Fahrenheit.  In reality I could have dropped the psi a bit to account for the increase but to be honest I thought more about the heat of my body then the temperature of the air in my tires.  

Today a few new toys showed up.  We will be logging temperature and a few other things in an upcoming tire study.  It should be pretty cool.  

Take care,
