Expert Review

It might seem like an oxymoron at first—a 70cc pro bike? Really? But don’t let that be a deterrent, you’d be doing yourself a disservice! This little engine that could absolutely rips, as an award winning ZongShen motor is housed inside, concealing a huge amount of acceleration for the engine size—this thing has to be seen to be believed! The small seat size can hold up to a whopping 198 lbs, which is close to almost double what almost any other 70cc bike can handle. Although the seat size might make it a little cramped for taller riders, this is absolutely perfect for smaller riders and even teenagers or younger looking to cut their teeth on a few races. It houses all of the features you’d like in a pro bike, like front and rear drum brakes, and a sturdy steel fork suspension, for an unbeatable price—what’s not to love?
