Wahoo Kickr Bike and Zwift for indoor winter riding

After nearly two months of waiting, I finally got my Wahoo Kickr indoor bicycle trainer. It was expensive, but so far I am very happy with our choice.

We decided to purchase a Wahoo Kickr dedicated indoor bike trainer so that it would be easy for both Kay and me to switch the bike so we both can ride. The bike works well with Zwift, including tilting up and down as you ride up virtual hills.

Sold my Giant TCX

In April I sold my Giant TCX to my son and purchased a slightly smaller Trek Checkpoint that fit me much better than the Giant. I really liked the TCX, but the frame was just slightly too large and I wasn’t able to easily get it to fit me.

In May 2020 I sold my Giant TCX to my son. I really liked this bike, but the frame was just a bit too large for me and I never could get it to fit just right. It had a power meter on the crank, which allowed it to send power readings to Zwift on my iPad.

Last winter I used the TCX on a dumb trainer for indoor riding on Zwift, a software system that allows for virtual indoor riding. I was able to use the TCX on a dumb trainer because I had installed a Stages power meter on the TCX crank. The power meter would send my riding metrics and power output to my Apple iPad via bluetooth.

Since I sold my TCX in the spring, I ended up riding my Checkpoint outside all summer and didn’t really feel the need for a power meter. So with winter fast approaching, I needed to decide how to ride on Zwift again. My options were:

  • Install a power meter on my Trek Checkpoint – $600.
  • Buy a wheel-on smart trainer – $500
  • Buy a wheel-off smart trainer – $1,100
  • Buy a smart indoor trainer – $3,500

Of course I liked the lower cost options best, but there were more factors at play this time. Now that both me and my wife knew I would put an indoor trainer to good use, we were willing to spend a bit more money, since we knew it wasn’t just going to sit in the corner unused.

I spent a couple of winter riding my TCX on a dumb trainer, with my power meter sending power readings to Zwift. It worked great, but Kay could not ride it since it was too big. I also had to connect and disconnect my bike fro the trainer every time I wanted switch from riding indoors to outdoors.

If I purchased a smart trainer that attached to my bicycle, then every time I wanted to ride outdoors I would have to unhook my bike from the trainer. Not a big deal, but it does take a few minutes of work and is not necessarily convenient.

Kay decides to try indoors

A major factor in our decision to spent the extra money for a dedicated smart trainer is that Kay felt she would also use the indoor bicycle trainer this winter. She only has a mountain bike, which requires different connectors to a smart trainer, so switching between my Trek Checkpoint and her mountain bike would be a bit of a hassle. I most likely would end up riding indoors more than Kay so usually my bicycle would be on the trainer, and for her to ride, she or I would have to unhook my bike, swap connectors, and hook up her bicycle, then reverse the process when I was ready to ride.

With a dedicated smart indoor trainer, it would be a simple matter to adjust the bike to fit either one of us, especially since we both use the same pedal length – Kay is 5′ 7″ and I am 5′ 10″ – enough of a difference to change seat height and reach, but not enough to change pedal length.

Setting up Wahoo Kickr Bike

I won’t go into the details of setting up my Wahoo Kickr Bike, since there are plenty of Youtube videos showing how that is done. The highlight is how easy the bike is to set up, and how customizable it is for each rider. It only took about 30 minutes to set the bike up in our den, and then about another 30 minutes to get all the software working and the bike customized to my liking.

The Wahoo Kickr Bike took nearly two months to ship, but was easy to assemble in my garage. I had it up and running in about 30 minutes.

I really liked how I could program in whatever gearing I liked on the bike. It could be programmed with my mountain bike gearing, my old TCX gearing, or my new Trek Checkpoint gearing. In addition, I can easily change the gearing to test out new gear sets while virtual riding to see how I like them for real-world riding. For example, I have a Shimano GRX gravel group set on my Trek. It has 46/34 teeth sprockets on the front chainring, and an 11-speed 10-34 sprocket on the back. This is slightly lower gearing than some people choose. I can try out different front and/or back sprocket sets to see what works best for climbs or flats, and then order the gearing I need for my bike. Pretty sweet!

Since I like to weld and fabricate things in my shop, I created a stand for my iPad and iPhone out of thin-wall 1″ square tubing and some plywood.

Overall I really like the Kickr Bike and my wife has also enjoyed riding it. Now we can both ride the same morning with just a quick adjustment of the seat height and reach. And when I want to ride on the road, I just walk into the garage and jump on my Trek without having to unhook it from the trainer. To us, it has been well worth the extra money.

I have an older iPad that I leave on the stand I built. It runs Zwift and connects to the bike via Bluetooth. As I pedal, the power and cadence is transmitted to Zwift to power my virtual avatar. While Zwift is not really necessary, it makes riding the indoor trainer fun and less boring than just staring at a blank wall or even a television screen. I can program Wahoo Kickr to mimic the gears on my actual bicycle so I have to shift to lower gears going uphill, and higher gears going downhill. In addition, the Kickr Bike pivots up and down to mimic climbing hills on the bike, which is a fun feature that adds to the realism. My phone runs Zwift Companion, which is used to show a map of the virtual world I am riding through.
Before COVID I often road this Keiser bike at the YMCA, but now, not so much.
