Description: Grenade B2 BMX Bike 20in

Following a line of great bikes, the Grenade B2 BMX Bike is the third in a line of "beginner" street bikes geared towards the younger, novice crowd. With that in mind, safety is number one and this bike comes with Framed grips and the Framed Pipe Bomb 175mm Tubular Cromoly Cranks (with Cromoly Spindle) for protection. The frame is made so that upgrades to wheels with 14mm axles (for example) can be done without buying a new frame/fork. As a whole, the Grenade B2 BMX is a great base bike - and primed for upgrades galore.

What size grips reccomended for the bike??
A shopper on Jul 18, 2015
Best Answer: The length of a grip and its flange style is completely personal preference. The vast majority of BMX bikes have a standard handlebar diameter. If you are still curious have a chat with our bike shop: 1 (800) 409-7669.

is this bike good for bowls,ramps,and jumps?
A shopper on Sep 29, 2015
Best Answer: I bought this for my 13 year old sun who is avid skateboarder as well. He is very happy with it and he has used it on a very intricate BMX site near our house. It is excellent for bowls, ramps and jumps and its price point from the House can't be matched. Dollar for dollar, excellent value
