Workable for casual, flat-terrain riding and portability, but budget the cost of a local shop tune-up and don't expect gym-grade durability.

Overview
A folding mountain-style bike with a carbon steel frame, dual disc brakes, and 21 speeds, sized for 26 or 27.5 inch wheels depending on the listing variant. Ships about 85 percent assembled, needing the front fork, wheel, seat, and pedals installed before riding.
- 21-speed drivetrain
- Dual disc brakes, front and rear
- Folded size roughly 1050 x 320 x 920mm
- Weight limit 330 lb
Who it's for
Suits riders who need a bike that folds into a car trunk or small storage space for light trail or paved riding, and who don't mind a trip to a local shop for a post-assembly tune-up. Not a fit for anyone planning serious mountain trail riding or wanting a maintenance-free bike.
Pros and cons
- Folding mechanism works smoothly, fits in car trunk
- Sized for riders roughly 5'5 to 6'1
- Dual disc brakes included
Performance notes
The folding hinge adds weight versus a standard frame, and while the mechanism itself works smoothly, the drivetrain and brake components have drawn the most complaints over extended use.
