Very Cool Bike

[This review was collected as part of a promotion.] This is a really nice bike. It's super sleek and lightweight. Rides smooth and can do bunny hops with ease. My first bike from mongoose and the quality is excellent. It only took about 10 minutes to assemble as most of it is already put together. Love the large pedals for extra grip.
