Overview
A 24 inch kids mountain bike with front and rear suspension, 7-speed shifting and disc brakes front and rear on an aluminum frame. Built for pre-teens and small teens stepping up from a hardtail into a full suspension trail bike.
One detailed reviewer liked the frame quality and correct suspension geometry but flagged a rear shock with no damping and brakes worth upgrading to hydraulic. Sizing runs tall, fitting a teenager better than the 8-11 age range it targets.
- 24 inch wheels
- 7-speed drivetrain
- Front and rear disc brakes
- Aluminum frame with front and rear suspension
Who it's for
Suits taller kids and small teens who want a real full suspension trail bike rather than a basic single-speed. Less suited to the youngest end of the 8-11 range this is marketed for.
What buyers say
From Amazon customer reviews.
Reviewers praised the frame quality and correct suspension geometry, with one calling assembly very simple and another repurchasing a second matching bike. Complaints centered on a rear shock with no damping, brakes reviewers felt should be upgraded to hydraulic, mediocre plastic pedals, and one unit arriving scratched with anodizing flaking off.
Strengths and trade-offs
Drawn from this product's published specifications.
- Full suspension frame at a kids bike price point
- Front and rear disc brakes included
- Reviewers found assembly straightforward
- Rear shock lacks damping per one reviewer
- Stock pedals are plastic and may need replacing
- Sizing runs tall for younger kids in the stated range
Performance notes
The front fork has limited travel per one reviewer, and the rear shock was described as stiff with no damping, so bumps transmit more than on a true trail bike. The frame geometry and pedaling efficiency were called correct, with no energy wasted compressing the rear shock.
