Replacing My Crank & Sprockets?

Question

I have a Raliegh Matrix MTX 360, yes its awful I know, I want to replace the crank and sprockets.

But it doesn't have standard cranks they are sort of screwed together in one continuous piece.

Also, the bike cost me £75 (GBP) brand new, would I be better off buying a whole new BMX?

Answer 1

I Guessing You Got A 1 Piece Crank :

To disassemble a one-piece crank, start by removing the left pedal (turn it clockwise to unscrew it--everything on the left side of a one-piece crank is left (reverse) threaded.) Then remove the lock nut on the left side bottom bracket (clockwise to remove), lift of the keyed washer, and unscrew the left cone (clockwise to remove.) The left cone usually has grooves that allow you to turn it with a flat-bladed screwdriver. Pull out the ball retainer, then you will be able to withdraw the whole crank assembly from the right side of the bottom bracket. Pull the crank part way out of the bottom bracket, then reach in and remove the right side bearing retainer. If you try to pull the corners of the one-piece crank through without removing both retainers from their cups first, you may damage the retainers.

And Buying A BMX No Don't Bother They Sound Good But They Hurt Your Back And Not Good For Traveling Assuming That Is What You Want A Bike For.
