Hello ColdBreeze, sorry to hear of your cycling woes. OK a bit more information I will assume a few things here. how old is your bike?what kind of bike? Moutain, Road, Singlespeed? type of crank Shimano, SR, Sugino?

OK I will asume your bike is midlevel say 4 years old. you have the bolts or nuts off that hold the cranks on and you can see the square bottom bracket spindle right? at this point you need a crank puller to take the cranks off that spindle.

as for your pedals they are likely on very tight but you should be able to remove them, a pedal wrench is a great help here more leverage, by turning them to the rear of the bike. doesn't matter which side they both turn to the back to come off

checkout the Park tool website. they have lots of great instructional videos http://www.parktool.com/

PS I get alot of greif for saying this here but you may be better off taking it to the shop. yes you actually have to pay them to do but they have the tools and knowledge and you can relax and have a Cappicuino while they deal with the aggrivation LOL

that is why my car goes to the shop. I could do it, but they have the lift and the fancy tools..

OK, according to Google Next Rampage is a BMX out of Wal-Mart, at the princely sum of $74 as new. Unless the Bike Fairy appears and hands you spare parts on a platter together with a voucher for getting them fitted free - start looking for another bike. At that price it basically can't be repaired w/o the repairs being more than the bike is worth.

If you want to use it as a learning experience, do a net search for "one-piece crank" or "ashtabula crank" which is what you have. Sheldon Brown has them covered.

OH yes that BMX part would have been a big help :thumb:
