Installing a mid bottom bracket is very simple. All you do is tap both bearings into both side of the frame evenly, they do not have threads or anything like that its just simple pressure, don't hit it to hard though because you could crush the bearings.
On the most common bicycles the bottom bracket is the bearing assembly that the crank arms and the pedals turn in.
Yes, if you can find the correct bottom bracket for the frame.
BB usually stands for Bottom Bracket, the part which holds the cranks/pedals to the bike
It'd be a fairly strange BMX if it has a gear shaft. Most "real" BMXes are single speed, their driveline consists of cranks, a bottom bracket and the rear hub. No gear shaft there.
Too long to answer here, there's half a dozen or so of styles. check out www.bicycletutor.com, www.parktool.com or www.sheldonbrown.com for pointers.
yes... if you have the right bottom bracket... it has to fit the cranks as in 19 20 21 or 22mm most likely......... and it has to be the right size for the frame.. if its bmx it will probably be US size or euro, spanish or standard. if you find the right bottom bracket with the right size bearings then yes..
You can remove bearings from a BMX frame with a 'mid' bottom bracket without damaging them using a 3/8s rachet extension.
One can buy a custom BMX bike in Las Vegas from a few stores. One can get a BMX custom made from 'Just BMX', 'Bolder BMX', 'Bike World' and 'Vegas Bike Store'.
When the Interceptor first came out, they were GT's bottom of the line BMX bike. It's a better bike now, but still a low end bike.
It's a BMX racing bike for beginners. What we would call a "Junior" size (pre-teen). It's a strange mix of entry level and high end. For example, it has a hi-ten steel frame, plastic pedals and unsealed hubs, yet it has a sealed bottom bracket and a Cro-Mo three piece crank. It's a small bike as it has only a 19 3/4" top tube and an "upside down" style handlebar stem.
A hyper is better
no but you can get a dirt bike or a cruiser bike or a speed bike but i havnt seen a bmx bike yet.
The type of bike that is mostly used form BMX riding are the purpose-built BMX bikes.
