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.
