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).

  • Simulate outdoor riding with this refined indoor smart bike
  • Pair with Zwift and other apps for automatically controlled resistance
  • Electronic shifting, braking, and steering for a realistic ride feel

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.


Could someone please confirm that this is actually the Stages SB20 and not the previous version of their SmartBike? Thanks

(Leaving out the shipping issue as that has nothing to do with the bike.) Easy to assemble Set up with Zwift was a piece of cake on my I phone mirrored to a big screen. Bike is super quiet Workouts on zwift are amazing I added a tickr heart rate monitor...the training data is awesome. Bike is infinitely adjustable and rock solid I have generated 1000 watts on a standing climb and this thing is like a tank. Love!

Really dissatisfied -Updated

I've used it once or twice and have initial impressions

After months of research (DC Rainmaker, Velonews, etc) I decided to pull the trigger on the stages bike. After patiently waiting for a few weeks after ordering, the bike arrived. It was fairly easy to assemble. It felt sturdy. It easily synced with third party training applications. At first I was psyched. It worked for three rides. The flywheel started making a knocking noise. I followed the trouble shooting guide on stages website with no success. Stages customer support is recommending a replacement flywheel. Not sure how long it will take to resolve the issue but at this point it’s an average of $1,000 per ride. In retrospect I think I may have gone with a tacx or wahoo. Update: I contacted Stages for help resolving the issue and have essentially been waiting for three weeks with no solution. provided no help. I would highly encourage people to look at other smart bikes not sold through backcountry. I want to love this bike, but so far disappointed.

Not sure if it’s worth it but close

I have a Wahoo setup with a Saris Nfinity platform and that is what I am comparing the Stages to. Pluses: very quiet. If the flywheel is aligned properly with the belt upon arrival (mine wasn’t see cons later) then this thing is like a barely noticeable low vibration unless you average 250+ W. Not sure you could ride it in an apartment but far quieter than the Wahoo setup. Stages says 50 db or so. Unlimited gearing and grade simulation options with the Link app. This is a cool way to test if you can handle say 25% grade with your 34x34 gearing etc. or see your left:right power balance in real time or see what gear you’re in. You can setup any kind of gearing imaginable up to 3x50. Fit: while not perfect, the range is far greater than Stages advertises. My 8 year old (~52 in tall) can fit this bike at the lowest bar and seat settings with a 165 crank. While that’s a bit long for my kid I doubt his bikes are running 140 cranks either. In order to move the bar closer to the rider you have to remove 4 bolts and flip a plate prior to installing the bar. I’m 6’1” with a somewhat short reach and I was fine with that as the stack can go very high. The shifters and even the functioning brake are nicely done and if you want to add some style to your bar and tape you can. There are two USB ports so you can charge a few devices at once. The negative: Get your tools ready! This thing took a decent amount of work to assemble. The box is not too big but it arrives freight and it helps to take down all sides of the box and bolt the feet on once you generally have the bike on level ground. Then you can roll it like a spin bike. Those not handy may want to find a bike person to assemble this as I found all of the bolts and moving pieces lacking grease and some of the directions were lacking descriptions. Mostly straightforward. What was bad though were two things: Stages knows that the belt / flywheel may come out of alignment or with improper tension. This leads to the belt moving sideways and rubbing under load (250+ W) which results in a noticeable rubbing sound. Fixing it is straightforward and they will even send a tech out to do it but it’s still a pain to need the tools so soon. Within the first 4-5 hours of use the bar started to creak. This wasn’t a small creak but a sound like something cracked or broke. Since the bar never really felt totally tight like I would expect using the reach adjuster no matter how hard I cranked it down. Additionally, that entire piece was out of center by a few degrees. These aren’t huge things and I get this is a first gen product. However, compared to my Wahoo with the Saris Nfinity I’m not sure it’s worth it as an upgrade for purely cycling purposes. In comparison the Saris platform feels far nicer in pedaling feel and my overall muscle development more closely resembles riding outside with the platform. In addition, I‘m not sure if my power numbers are different but I’ve mostly done lower efforts on the Stages. Finally, swapping pedals is a pain. Normally bikes have nothing blocking the wrench from entering the back of the spindle. With the Stages the housing prevents a clean entry which means pedals lacking wrench flats will be very slow to install and remove. If you never want to own a bike for riding outside then this is your ticket to Zwift. If you have a bunch of people in your family Zwifting then this is also a great addition especially for kids. There’s still the hassle of setting your fit and also deciding on pedals and crank length so the main plus for multiple users is not having to keep multiple bikes inside the house or swapping cassettes. I think if you’re going into winter with no high-end indoor setup and you can only choose one setup I would test the Saris platform and the Stages. The Saris isn’t even close to perfect but might be the better upgrade to your indoor training,

This was a replacement for my Computrainer and love the bike. I looked at the Watts and Wahoo as well and watched the velonews review. I looked at a bunch of other reviews as well and this bike was the best choice for me. Pros- watch the velonews review it's pretty spot on not much to add. The only thing is the included holder for an iPad has a bunch of cool options for phone holder as well. Cons - I would say it feels less sturdy than I thought. It's heavy so make sure you help moving it. ThIs is an issue when you try and place the bike in front of a tasked with a screen / computer on it since the wheels are in a position that when you tilt and move the bike it just doesn't get close enough. A couple of annoying things I'll have to figure out - The shield around the drive belt rubs on the fly wheel. It took a while to set up with zwift. Not having a gear indicator is a real pain.

I have a Stages Bike and to see your gearing you need to run the Stages Link where you can setup any number of gearing configurations from “dream” ie 2x50 or some specific setup and then as you shift you can see what gear you’re in. It’s pretty cool! Also, you can use the app to calibrate and update firmware as well as see your Left:Right balance. I haven’t quite figured out how to get the left right data into a better tracking/analysis program yet but I’m sure there’s a way.
