Help me pick my first BMX bike

Hey,

I'm 35 years old, bike a lot on the road and MTB, and am just now catching the BMX fever. But I have no idea how to fit a BMX bike. I will most likely ride on the street just for fun. I'm 5'11", and weigh about 180. I looked at the Specialized FatBoy and the K2 Ghetto tonight, just because they were what the store had on the floor. Any suggestions for frame/wheel size, etc? I know nothing about BMX.

Thanks.

the only real sizing issue is top tube length...most bikes have about a 14" chainstay, and the seat tubes are pretty much all the same length: too short to make any really noticible difference unless you've been riding long enough to tell, and even then...

basically, i'd reccommend that you get a bike with a 20.5" top tube or longer. the longer ones are 20.65", and 21".

wheel sizes...hmm... basically, there's 20" and 24". if you want to do tricks and such, get a 20" a 24" might fit you better, but they can be more difficult to manuever, and not a lot of people ride street or ramps on them...they're more for dirt jumping and racing...mostly racing.

the specialized should be just fine for you now, as long as it has 3 piece cranks.

or if you've got the cash you could always get a really nice frame (standard, T-1, kink, FBM, Fit) for around $300 and get all the parts separately, and get exactly what you want. but if you're just starting out, i'd say go for a reasonably priced complete bike with 3 piece cranks and start ridin'!

what he said... your not that big so probably a 20" wheel (triplewall) and 20.5"top tube. definitly get three-piece cranks. try to get the bike around 30lbs... for ur size though a heavier bike may not matter (if u got muscle). test some bikes- in the past 3 years i've been on 5 bikes- just trying to figure out what i need- dont waste money on biuilding a bike until you knoe more about the right parts for u
also read up on the new and best parts on the market- online auctions never fail to get the best for cheap!

Ok, I can't tell what is meant by 20" wheel.
Is it 20" from the floor to the top of the tire, or is it a 20" rim plus tire(I'm guessing around 23" or something)?

Thanks,

Jacob

a 3 piece crank is when the bottom braket is separate from each crank arm. They are the strongest but also the most expensive type of crank
