Why We Like The Smart Bike

When we hear the name Stages we tend to think of their world-class power meters, but what many people may not realize is that Stages has been making stationary bikes for gyms, cycling studios, and the consumer market for many years. It's a big part of their business, and with this level of experience, they certainly know how to build a durable and functional exercise bike. The all-new Smart Bike represents their voyage into the realm of resistance-controllable units, and promises to take your training to the next level by bringing a realistic outdoor riding experience to your indoor training sessions.

To get the most out of the Smart Bike, you'll want to pair it with applications like Zwift to reap the benefits of automatically controlled resistance, electronic braking/steering/shifting, and all the metrics you need to track your progress. The programmable shift buttons let you customize your gearing and shifting preferences via the Stages Link app, and the brake levers work just like a regular road bike, slowing down the flywheel and your cadence while providing a matching response for your Zwift avatar.

The Smart Bike is equipped with a Stages Gen. 3 dual-sided power meter that measures left and ride side output with +/- 1.5% accuracy, and there's a secondary power meter in the flywheel that cross-references these measurements for consistency. The bike has fully customizable geometry that makes it easy to match the fit of your outdoor bike, meaning it's always ready to go when you have time to squeeze in a workout, and you'll never have to waste time setting up your race bike on a trainer just to take it all apart again when good weather beckons you out for a ride.

Other notable features include integrated tablet and smartphone holders in a secure and easy-to-read location, along with two fast-charging USB ports to keep your devices charged throughout the workout. Two water bottle mounts make it easy to stay hydrated during longer training sessions, and you can even mount your favorite saddle or handlebar to further customize the bike to your individual preferences (including triathlon and TT bars).

Better than expected

I've used it several times

Coming off a Kickr Core this thing does EVERYTHING so much better. On the Kickr it always felt like I was being pretty hard on my drive train. The SB20 is silky smooth and silent. People knock it for not having any LCD displays etc but one could just grab an old smart phone out of the drawer and use it on the SB20 full time to display gearing, etc. I had the budget to go with the Tacx, Kickr or Stages and went with the Stages because it has less gimmicks to break down the road.

Game Changer for Serious Riders

I've put it through the wringer

We purchased the Stages SB20 smart bike over a year ago and have put it through the wringer. I was never a fan of indoor riding prior to this purchase. But with Covid shutting down our local gyms and winter spin classes, we opted to create our own indoor pain cave. After much research, we settled on this bike primarily because Stages has been a leader in the production of indoor spin bikes and the reviews by GPlama & DCRainmaker were excellent. Over the past year I've ridden somewhere between 10,000-12,000 miles on this bike. Setup was relatively easy and I'm usually a bit of a noob when it comes to this type of stuff. The bike works flawlessly: quiet, super smooth and rock solid. I guess the best testimonial is: would you buy it again? In a heartbeat. It's totally upped my riding game, my overall conditioning and now I don't dread the cold,dark winter months.
