Bottom Line

Pros

Cons

Best of the Best

Mongoose

Mongoose Legion L60 20" Wheel Freestyle Bike

Check Price

Bottom Line

Lightweight enough for BMX stunts and tricks, but we recommend replacing the original inner tubes first. Sturdy construction and high weight capacity for adult riders.

Pros

Very easy to assemble and tune. Not as heavy as traditional Mongoose models. Frame is stylish and sleek, easy to maintain.

Cons

Original inner tubes are not high-quality. Not durable enough for heavy "trick" riding. No kickstand provided.

Best Bang for the Buck

Mongoose

Bmax Boys' Fat Tire Bike, 20"

Check Price

Bottom Line

For younger riders who want the stunt capability of a BMX and the versatility of a trail bike.

Pros

Combines elements of off-road and BMX bikes. Designed for younger riders, but adults can ride, too. Rugged construction. 20-inch fat tires can handle a wide variety of terrain.

Cons

Assembly can be very challenging. Brake components are not high quality. Handlebars remain loose even after adjustments.

Mongoose

Massif Boys' 20" Fat Tire Bike

Check Price

Bottom Line

A heavy cruiser, not a BMX stunt bike or sprinter. Younger children may find it difficult to pedal, but older riders will enjoy its impressive design and all-terrain performance.

Pros

Heavy duty construction, will handle difficult terrain. Assembly only requires one Allen wrench. 7-speed Shimano gear system.

Cons

May not arrive with assembly instructions. Some critical parts are plastic, not metal. Very heavy, challenging for younger riders on steep terrain.

Mongoose

Girls' LSX Bicycle, 20"

Check Price

Bottom Line

The LSX girl's Mongoose is not designed for stunts or racing, but it does provide a smooth ride over flat and moderately hilly terrain. We suggest upgrading the braking system for younger riders.

Pros

Frame is very sturdy, provides a smooth ride. Extremely easy to assemble with minimal tools. Adjusts easily to growing riders. Great price for a genuine Mongoose.

Cons

Paint has durability issues. Some critical components made from cheaper material. Single rear hand brake system, not ideal for younger riders.

Mongoose

Girls' Maxim Full Suspension Bicycle, 24"

Check Price

Bottom Line

While some younger riders may find it a bit heavy, the aluminum frame provides a lot of stability and durability. Arrives almost fully assembled, and major parts can be easily upgraded or replaced if necessary.

Pros

Easy to assemble straight out of box. 21-gear derailleur and suspension fork provide easy, comfortable ride. Size is good for both youth and adult riders.

Cons

Some reports of missing or broken parts on arrival. Frame may be too heavy for younger riders. Stock derailleurs are problematic.
