What size riders will fit on the SB20?
The SB20 is designed to fit riders from 4'10 to 6'10. To accommodate this range, the bike features 4 crank length options and a large range of adjustability for saddle and handlebar position.
The bike has a weight limit of 300 lbs (136 kg) due to the infinitely adjustable seat height, which can slip when used under heavier loads. For safety, we cannot recommend the bike be ridden by anyone over 300 lbs.
If you have existing bike fit details handy, you can also consult the Fit guidelines in our User Guide to see the range of seat height, handlebar stack, and handlebar reach.
How do I adjust the resistance or change gears?
The Stages Bike features shift buttons located on the inside of both brake levers, as well as a secondary set of shift buttons in the drops of the handlebars. The two buttons by default will operate similar to a road bike, with the buttons on the left side working as larger shifts (big to little chainring) and the shifters on the right performing smaller gear changes.
Can I use my own saddle?
The Stages Bike accepts standard, dual railed bicycle saddles of nearly all types. You can easily remove the stock saddle and install your own to enhance the comfort of the bike. For details on how to change the saddle, see the user guide.
Note that only metal, round-railed saddles should be installed onto the bike, as the shape of carbon railed saddles requires a special clamp.
Does the Stages Bike come pre-assembled?
The Stages Bike ships to you partially assembled. The assembly process takes around 30 minutes including unboxing/removing packaging and all the tools are included (with the exception of a box knife that will be needed to open the package). Due to the weight of the bike, we recommend assembling the bike with a partner for ease of unboxing and assembly.
Can I change the handlebars?
The Stages Bike uses standard 31.8 clamp road handlebars. By using existing handlebar designs, all of the controls for the bike are removable and able to be installed on another set of handlebars. So long as the handlebars use a 31.8 clamp, you can use them on the bike. Aerobar extensions can also be added to the handlebars.
Does the SB20 make noise?
The Stages Bike uses an enclosed belt-drive system, which produces almost no noise. Expect around 50-55 dB of ambient noise while you are riding the bike.
What size tablets can be mounted to the bike?
The tablet holder can fit up to a max tablet size of 12 × 8.68 × 0.27 in (305.7 × 220.6 × 6.9 mm). The tablet holder can also be used as a phone mount (in either landscape or portrait mode) or you can use the phone tray holder on top of the stem.
Can I match my road or other bike fit to the Stages Bike?
The StagesBike SB20 is designed to be easily configured for nearly every rider. With a large range for saddle and bar height, fore/aft adjustments, and infinite settings within those ranges, the Stages Bike can be dialed in exactly to your specifications.
In addition to fit adjustments, the bike uses standard saddle and handlebar (31.8mm) mounts, allowing you to add your preferred saddle and handlebar onto the bike. These features, combined with the 4 crank length choices and your own pedals installed, allow you to replicate your existing bike to optimize your indoor training.
See the Fit Guidelines section of the user guide for exact ranges for saddle and handlebar height and fore/aft.
