Yes, if you can find the correct bottom bracket for the frame.

It will if you have bmx (or bmx style) cranks.

No simple answer to that. Both BMX and MTBs have several different types of bottom brackets. Some of these are interchangeable, some aren't.

take the cranks off and then take your old sprocket off and then put the new one on and then put the cranks back on.

Five. One for each wheel, one for the cranks and one for each pedal.

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.

A true childrens bike will have all the parts adapted to size, brake levers, crank arm length, handle bar width, saddle size etc. A BMX although its small overall size can very well be intended to be ridden by adults, so it can have long cranks, a wide handlebar ASO. While a kid may well be able to straddle a BMX, this isn't proof that the bike fits the kid.

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'.

There's no such thing as a trick bike buddy. A bmx technically is a "trick" bike. So just get a bmx if you want to do tricks.

Go to bike shop or wolyworld and buy a link remover.

All mongoose bmx are horrible! if you are looking for a good bmx bike look at Fit, kink, haro bmx bikes.

The bmx thruster rampage bike is a exellent bike

you can find a BMX bike in halfords

it is easier to pedal with longer cranks because you have more leverage but it is not necessarily better to have really long cranks.

No one. BMX riding didn't take off until a lot later, in the 1970s.

no but you can get a dirt bike or a cruiser bike or a speed bike but i havnt seen a bmx bike yet.

Pretty much whatever you feel like. Do you want to go faster, but can't spin the cranks any faster? Get a smaller one. Do you feel like it's hard to get the bike moving? Get a bigger one.

This is by no means set in stone and is highly subjective as every single company has had snapped cranks returned to them under warranty but, here's my take on the subject after looking for some new cranks for my own ride. Profile cranks are good and have set the standard for how most BMX cranks if not all function assemble and look. However, the design of the recent generation of their cranks have been going for some years (decades) now and that design has been updated by other companies who make their cranks in Taiwan except for Solid who are another good Us company with a relatively small output of cranks and products. This used to be frowned upon but, since the technology in the Taiwanese bike building industry has grown superior to the US due to better newer and more machines in factories, cheaper running costs and an understanding of how to make quality BMX products guided and designed by predominantly US and European bike companies although mistakes can still be made. My conclusion is that Taiwanese made cranks are now where innovation and aesthetics lie especially with the 2pc and 2.5pc designs and at the top of that innovation are Flybikes Cranks and Odyssey Twombolts after these two there are a plethora of for want of a better term - Profile clones with and without a 2.5pc axle/arm setup. 1,Flybikes 2,Odyssey 3,Solid 4,Profile 5,Take your pick its a big ocean out there!

it depends on what make and model your BMX or MTB is

A hyper is better

The type of bike that is mostly used form BMX riding are the purpose-built BMX bikes.

Bmx is riding a bike usually a Bmx bike while skateboarding is riding on a piece of wood with wheels.

for me it means that my crank arm bolt is coming lose, so take out you Alan wrench and tighten them

Pushing on the cranks puts tension on the chain, which rotates the rear wheel and pushes the bike forward.
