You have to set up sync. I could write it here but go to shimano.com and there are brilliant videos that talk you through gear sync. Very user friendly. No prior knowledge needed.

Based on the pic, I don't believe you can with out replacing the stem and/or the handle bars. Your local bike shop could give you a better idea of how to do so.

on the spraket there a small spring inside may its damage already.

pads bad? send a photo.

do an online search or go to fasenal

I expect you need to find 16in wheels, you could always contact the manufacturer for more help: http://www.dynacraftbike.com/customerservice.php

Yes. Loosen the two nuts on the back wheel. When they are loose just pull the wheel back until the chain is tight enough and tighten nuts while holding the tire in the proper position at the proper tightness of the chain. Make sure that the tire is running true when tightened.

You can contact dynacraft directly but you have to give them the serial number of the trike. http://dynacraftbikes.com/contactus.php

I have the razor scream machine which is made by the same manufacturer but dynacraft won't sell me the wheels unless I give them a serial number from their hotwheels powerslide model. Could you post the serial number on your trike? It would really help out myself and all the other scream machine owners who currently can't get replacement wheels.

Thanks,

Only thing different between all cables for bike is the lead stopper at lever end. Tell bike shop cable is for gears and type, lever or twist grip,and type of bike(mountain/BMX etc)for length and you shouldnt have any probs,*ALT* take lever end of cable to varify lead piece is the same.Your sheath on cable might be damaged-which caused cable to brake. Complete cable and sheath only cost about $3.Spray a fair bit of WD40/RP7 or similar down sheath before inserting cable for smoother operation.

you need get an extractor engineering tool. Go to engineering shop and get one or ask them to do it. You will have to rill a hole trough and by using the extractor screw it out . BUT one pedal got right turn tread and the other left turn.Other method it to weld some rod or bolt etc. on the bit what is inside and screw it out. Good luck

Yes you can add training wheels to this bike. The origional axle is too short, however, if you are mechanical enough, you can remove the axle and buy a longer one. I did this for my daughters bike, and for abot 5 dollars you can pick up a longer axle which will accept training wheels. But be warned, there are several bearings and you need to place them back in the correct position or the bike will not work.

I had a problem with the rear hub seizing up, clanking and screeching onmy Dynacraft Magna Imposter bicycle from the day I bought it at Target.I called the company and they sent me a new rear wheel. It arrived by UPSin 8 days and my bike has been fine ever since.Great customer service from Dynacraft!

Take it to a bike shop because it could be any number of things. It could be a very cheap fix like lubricating everything or as expencive as needing a new hub and cassette
