My Blackwater bike does not glide. The chain gets caught up. How can I fix that?

I would just stop by a welding shop and have them weld the pedal arm on. You can buy another whole bike for what it costs to get a helicoil like that done. If it's the left hand thread, impossible.

You can't bend it back you need a new one.

If the thread on the crank arms that hold the pedals are stripped, you will need a new set of cranks. That is definitely a job for the bike shop. Make sure the pedals are snug in the arm, Right side pedal has right-hand thread, left side (looking down when you are on the bike) has a left-hand (reverse!) thread.

Take it to a Bike Shop to get the cables and housing. This isn't novice work.

Get an idea of what's involved here...

You can use the 6 speed rear derailleur with no problems. The 5-spd shifter does not need to be disabled, as it will work just fine.

The shifter controls the rear derailleur, telling it how far to move. The rear derailluer just follows what is dictated, so there is no real difference mechanically between the 5spd and 6spd derailleurs, only in the shifter.

If you wanted to make the bike 6spd, you would have to change the shifter and gears along with the derailleur.

first thing is to check the cable itself.set the chain onto the small sprocket.now check to see if the cable has play.should feel like a guitar string.if not unloosen the cable at the front derailier.retighten using a pair of pliers to pull the cable tight as you tighten the screw back up.hope this helps

Does the sound come even when the bike is stalled and you accelerate it? If yes, then it must be timing chain and in case the noise comes only when the bike is moving, it must be the primary chain.

Go to parktool.com/repair for information on bike assembly, disassembly, repair and tuning. The assembly of any bike is more or less the exact same as any other, so this website will give adequate instruction for your bike.

Try this website and look under repair help:http://www.parktool.com/index.asp I think you are try to adjust your derailleurs. Also check this website under gear shifting:http://sheldonbrown.com/gearing/index.html I hope this will help.
