Overview
Off-road trails are the setting for this Mongoose, a steel-framed bike with oversized knobby tires and a rear derailleur. Alloy rims, a threadless headset and disc brakes at both wheels round it out. It arrives in a box and needs assembling.
Fat tires give a beginner a forgiving ride on loose ground, and disc brakes add stopping power. The frame is rigid with no suspension, and the rider height range is stated two ways, so confirm sizing before ordering.
Who it's for
Adults new to trail riding who want wide tires and simple gearing suit this bike. Riders who tackle rough descents or want a lighter bike should look at suspension models.
Pros and cons
- Wide knobby tires
- Front and rear disc brakes
- Seven speed gearing
- Limited lifetime warranty
- Rider height listed two ways
Performance notes
Wide tires spread the load over more ground, which helps on loose surfaces, and the seven speed rear derailleur gives easier gears for hills. With a rigid frame and fork, all the shock goes to the tires and the rider.
