For those ready to step up to the freedom and expanded range that gears provide, this sporty machine is up for anything from sidewalk cruising to trail blazing.
20” wheels offer a great blend of speed, handling and proper fit for riders between 3’10” and 4’3” (117cm – 130cm)
Lightweight aluminum frame and components make the bike easy to pedal, while the low standover make it easier to mount and dismount.
With versatile on-road and off-road tires and a bump-smoothing suspension fork, Trail 20 is built to build cycling skills and confidence.
