stagescycling.com/ NikkiThe Stages SB20 Bike was delivered to my doorstep basically as a complete package (their PNW HQ is only an hour away), making set up fairly easy for Casey and I. When you buy the bike new, you don't have that luxury of unboxed and pre-built delivery, so you will want to check out the in-depth review of the SB20 Smart bike by DC Rainmaker for beta on complete set-up. After I rolled the 138 lb smart bike into my office and swapped the stock road style drop bars for a set of low rise flat bars, I was ready to jump aboard and get my sweat on.
But not so fast! First came the pedals, which was waaay easier said than done. None of my pedals use a pedal wrench for installation—all of them use an allen key threaded through from the bike side of the spindle. And since the cranks are fairly close to the flywheel, there is minimal space for mounting these types of pedals. It can be done; however, be prepared to utilize about a three inches of rotation over and over and over to get the dang things on. Pedals that require a 15mm pedal wrench to install will help your sanity a LOT!
With my pedals finally in place, I was quickly able to adjust the bike for my height and reach while I downloaded the Stages app "Link" to configure the bike. Since I had the SB20 set up with an MTB specific bar, the app let me configure the gearing as if it were a MTB as well; for those looking to train in the gearing they race in, this is a great feature. The last step in set-up was getting the SB20 to sync to the training programs I was using. After some searching around the Stages site for support, I finally figured out that I simply had to turn the Bluetooth on my laptop off and then back on, and then whabaam!—I was finally ready to go. I would recommend that one take the time to watch the well executed and detailed Stages YouTube videos like I did to simplify setting up and configuring the SB20.
I started my testing using Zwift and Sufferfest; and excepting first world problems, like choosing a route or training plan, it was mostly smooth sailing. I quickly started to get a feel for the shifting (which is only available in non-ERG mode modules), and the Smart part of the training, i.e. using ERG mode. While you can just jump on the SB20 and pedal in their app, knowing your FTP or taking an FTP test is a good starting place for anyone new to the indoor trainer world in order to utilize ERG and get the most out of a trainer. I have an FTP from pre-covid gym classes, so I spent most my time on the SB20 in ERG mode in Zwift. As you will read below, Casey struggled with the 3-4 second-ish gap the bike had between power zones or in his case shifting. I wasn't doing any racing, so it wasn't something that really bothered me, but I did notice the delay. By comparison, the Kickr and the Neo 2T have almost no delay.
When it’s all said and done, this was one of my favorite of the Smart Trainers for a number of reasons: First, I was up and running on the SB20 within 40 minutes of seeing it for the first time. Secondly, while it’s a 138 lb. beast, I liked that it was heavy and stable because I could stand up and sprint without feeling like I was going to break something. I also like that it comes stock with a removable tablet holder, phone holder, and dual, easy to reach water bottle holders; on the other trainers I needed a platform for my phone or iPad. From a pure convenience perspective, I liked that I didn't have to use my own bike so I could jump on the trainer without removing a wheel, worrying about shredding an expensive tire, or taking a cassette off. If you are someone who is more likely to ride a trainer because it's ready to go all the time, that is definitely something to take into consideration. While we didn't review the Peloton bike in this piece, their popularity has exploded, and the Stages SB20 is similarly priced to the higher end Peloton, but it offers compatibility with a wider range of Apps and training programs.
CaseySetup on this bike was relatively simple. There were a bunch of hex wrenches that came in the box for easy swaps from the mountain bike bars to the road bars and back. Probably one of the best aspects of the SB20 was how customizable this bike is: we were able to get pretty good fits for my 8yo daughter, my 5’10" wife, and for myself. And while my wife and I have similar saddle heights, everything else between our preferred bike fits is different. If more than one person is using this bike, sticky notes or discrete sharpie marks make “bike” swaps fast and easy. Pedal swaps was another story though. Like Nikki, most of my pedals use an allen key on the inside of the spindle to thread on/off the cranks. With the Stages SB20, there’s just not much room between the crank-arm and the bike frame to insert your hex, so changing between pedals took way too long, and it was hard to get decent torque with the maybe 30 degrees I was able to turn my hex keys. If your pedals allow the use of a 15mm pedal wrench, then no worries.
As a stand-alone bike, this thing is rock solid. Even trying my best, I wasn’t able to rock it off balance. After hard workouts where your legs are shredded, having no top-tube made dismounting easy without tempting a hamstring cramp. At the same time, by not having that top-tube, it was hard to keep the crank area free from sweat. I found that this bike got more sweaty than trainers where I was able to put one towel on my top-tube and another across my handlebars.
Using the app was pretty simple for this bike. One of the best things is the ability to set the electronic shifters to essentially any possible drivetrain you’d like. You have the option of up to 10 rings up front, and 50 in the back. I’m not sure how well a 500 gear bike would actually serve, but if you want to that kind of range, it appears to be possible. That novelty wore off quickly, though, and I settled on a 12 speed 52/36 front x 10/33 rear, which provided a pretty solid range of gears for riding in Zwift.
In ERG mode, this bike really struggled to maintain consistent power. During workouts on both Trainer Road and Zwift I was constantly over or under the prescribed power level. Then, after a bit of low power, it would seem to try to overcompensate and set the tension higher to have the “average power” be correct. After a few workouts trying to figure out the bike’s trick, I turned off ERG mode in frustration, since I was able to maintain my own power much better than this bike's software could.
While ERG mode seemed to struggle with workouts more than any other trainer, the SB20 would read consistent power between my power meter and the bike. The sprints were picked up, and when I’d stop applying power it would read zero. This bike has essentially two crank-based power meters, and because of that you’re able to track things like power balance, pedal smoothness, etc. After a few years of having these metrics available on my own power meter, while I appreciate their availability, I honestly haven't looked at them since my first week of power meter use. However, I don’t have any injuries or power imbalances that I’d be tracking; but if you've got big imbalances in your legs or really rough pedaling, maybe you'd find more value with these tools.
A nit-pick: while this bike plugs in, the power meters that the bike uses are their own separate unit that require separate batteries. In the middle of one of my wife’s races, I started hearing a string of obscenities coming from the garage. Rushing out there, I found that the bike had started reporting a consistent 126 watts and she was quickly dropped from the group she was racing against. There was no prior warning to this, and even having connected the app earlier in the day, I didn’t know that this was coming. Fortunately we had some CR2032 batteries in the drawer and she was able to get back to racing the next morning. Lesson learned; keep batteries in stock or you might end up sleeping on the couch.

The other frustrating aspect of this bike was the delay between applying power to the pedals and that power being displayed on apps like Zwift, etc. When trying my hand (and getting smoked regularly) during races, this bike was always a few seconds behind the curve. When you’re trying to hang-on to the virtual group, being several seconds behind the curve makes it really hard. I’d find that I was either off the front (apparently attempting to break-away), or struggling at the back. Consequently, it was really difficult to stay with the group when there were fast changes in power. For consistent efforts like time-trials, this was a non-issue. But in a pack, as soon as you see someone else is putting the pressure on, you’re caught on your heels.
For me, this was a deal-breaker. I never did a Zwift race before doing these trainer reviews, but after getting into them during all this trainer testing, that lag made a fun activity frustrating. At the same time, my wife also got into virtual riding and the Stages bike was her go-to tool. Like Nikki, she liked jumping on this as well as the more up-right position that you can set on this trainer vs. deconstructing her bike for a direct drive trainer or the Saris wheel on trainer.

No one wants to belive it...
The best part is that if you're on a trainer and you forgot/run out of water and snacks you just mosey over to the kitchen.
Set up the trainer next to my GF, we are binging Battlestar Galactica
I can see the potential benefits, but putting a mountain bike one one is something I don't understand at all.
I prefer other forms of exercise in the winter but that's just me. I can't think of anything worse than being stuck out there in the garage for hours on end in the dim light, damp and cold. There are plenty of other sports that also help with fitness and also involve doing something other than sitting and spinning.
I'm cool with it if that's someone's bag but it's not mine.
Also, a used road bike with a proper pedalling position and a used trainer is definitely a better proposition than putting an enduro MTB on a trainer.
If it were just me, no way I'd drop the coin ($3k I think), but sharing it across 4 family members and the ability for all of us to re-size and ready it in 30 seconds or so gives it the win.
I'm in the process of building a mount so I can get my laptop up there and work while I ride which should help me burn off some of this extra Covidsulation.

Tacx Neo 2 owner here. Two years in and loving it + Zwift.
I'm running a Kickr Core without a fan currently (in a cool garage - can't imagine using a trainer at 68F/20C indoor temperatures), and I do get pretty drenched by the end of a workout, even with lots of toweling off.
If I had to shop for a trainer now, the Wahoo Kickr looks like what I’d want to get. I think pairing that with one of their computers would be a good way to keep things integrated, and I’ve always wanted to try out Zwift.
I do have a high heat tolerance though, so I can get by with a small fan. No fan at all if it's just a recovery ride.
I would agree that the setup is a little bit of a pain, and that it does need to be calibrated each time, but that's a pretty minor thing to deal with. I run it with just my Garmin GPS, have yet to enter the whole online training bit, but love what it is, does and will do for me. If you are on the fence, I'd say get it. And do be sure to get a trainer tire. It does so much better, and so much quieter with one.
The latest GCN training video kills me every Monday, Wednesday and Friday after work.
I would love the spare cash to spend on a complete ZWIFT setup but I think I would live on it, it looks ace.
Until then, my cheap setup that cost me £150 in total will do. It hurts all the same.
I do have a free 37" LCD TV connected to my phone and a nice garden building to ride in too (made from recycled.. really cheap.. windows)
"Lose the use of"? If it doesn't fit, then how is a 10-50 HG cassette possible? Do you mean you leave the 10T off? Do they supply a spacer?
For those who don´t know, speed in the Zwift game is adjusted so gearing on the trainer is relevant. Just as in real life you will get dropped by roadies because you run out of gears. A watt should still be the same watt for everyone but to virtually adjusting would be great for MTB and make flat and downhills relevant i the game.
Also, after owning MANY wheel on/wheel off trainers over the past 20 years... once you go to a purpose built iindoor trainer - nothing else compares. My nice outdoor bike is no longer getting trashed. And the SB20 is actually made to be sweat on ;->.
Just as an aside, I remember a mate a decade or more ago doing some winter training on rollers in his garage. 26" MTB on slicks...liked MTB but more a typical roadie. For some bizarre brain faded reason and perhaps chock full of stoke, he decided to dismount with a bunny hop. He was quite fortunate that the wall he ran into was mostly drywall... mostly.
It is the nap time saviour of my life.
I hate it. She hates it. My assessment is simply -> like a stationary gym bike, but without the comfy seat or fan but has gears. I'd rather ride my MTB on gravel or the road for that matter. Don't get me started on the zwift aspect of it.. total let down.. if I want to fire up a video game - lets get the fun stuff in there like super mario cart type of action.
That all being said, I am fortunate to be able to ride all year round, but even if I couldn't.. I'd rather get my spinning in on a normal gym bike.
Tacx neo 2t accuracy less than 1%
Kick'r accuracy +/- 1%
So tacx is more accurate by there own claimed specs of both...
Like many home gym products, people buy spin bikes then don’t use them, they sell em for cheap on Craig’s list.
Gyms also sell used spin bikes.
For ease of use and to get a quick fitness fix, a spin bike works best.
For compact, occasional use or as a dedicated trainer, a resistance rear wheel trainer is great. Using you mountain bike requires fussing with set up and break down, which is fine if you’re snowbound for winter, but if you ride during the winter you’ll probably want a dedicated bike for your trainer.
Rollers are simply the best if you want to ride indoors, yes they take practice, yes they require more focus, BUT that’s part of the training too.
I think about spin bikes and rear wheel trainers like lifting weights in the gym, narrow purpose, not “natural“.
I think of rollers like CrossFit, it’s more practical, it’s harder, but it’s also more fun and better for you.
The biatch about rollers is you need a roller specific bike. I no longer ride bike, so my trainer of choice is a spin bike. I also mountain bike year round, two to three rides weekly even in the middle of winter.
But let’s face it, unless you’re a spin nazi or gym rat, indoor training sucks.
I have F-Su off every week, so I’m going riding for the next three days OUTSIDE!
Whats so cool (apart from the weather) about riding outside all year round? Its just ridding.
however if you want multiple family members to use the same trainer than a stationary bike is a better direction to go of course.
Just no point bothering with the paid version now as there's no way of knowing what people are using. I'm seeing a lot of profile pics with quite rotund people beating a lot of very good sponsored riders.
