Description: Grenade B2 BMX Bike

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 of bike do I get I am 12?
A shopper on Aug 7, 2016
Buying BMX bikes is a little different than normal bikes. To begin with... your age makes no difference. If you are like 5' to 5'10 you can ride a standard 20" BMX bike with either a 20" or 20.5" toptube. If you are taller you will to look at a bike with a 21" toptube.
if I get this bike+shipping how much will the total thing round up to if I have a bike shop assemble it? And if my budget is 250 what is a good bike that with the bike and shipping and assembly is under 250?
Charlesm on Jun 21, 2016
BEST ANSWER: Hi Charles,
There is a lot of variables here. Shipping will depend on where you live and what method you choose. Shipping is going to be about $19 and assembly will be between 15 and 25 bucks (that can vary quite a bit).
