Overview
A 26 inch, 21-speed folding mountain bike with front and rear shock absorbers and disc brakes, built for riders roughly 5 feet 3 inches to 6 feet tall and up to 220 lbs.
- 26 inch wheels, 21-speed drivetrain
- Front and rear shock absorbers
- Folds flat with no tools, no electric assist
- Fits riders roughly 5 feet 3 inches to 6 feet tall, up to 220 lbs
Who it's for
Fits riders in the 5 foot 3 to 6 foot range who want a folding bike for trunk storage or apartment living and don't mind troubleshooting assembly with a video guide when the printed instructions fall short. Less suited to anyone near the edge of or outside that height range, or buyers who want a bike ready to ride straight out of the box.
What buyers say

Reviewers generally liked the look, price and ride quality, several specifically praising the frame strength and suspension, but recurring complaints centered on setup: the included instructions were reported as unclear or for the wrong bike, pushing buyers toward YouTube to assemble it. Multiple buyers also reported hardware issues on arrival, including a bent disc brake and a missing bearing ring, and several mentioned the stock pedals or seat needed replacing, one noting the plastic pedals broke.
