my rear wheels locked up and i dont want to take much apart without knowing whats causing it but the rear wheels will move with alot of pressure but it takes alot of force and i was thingking the rear gears but if anybody has an idea of what it is or what i could do to check and see what the prob is it would be really appreciated.

 

Take your axel off grease it and the bearings on the inside and put it on but not the wheels yet. Then spin it a good 5 times than do it with the wheels on. You got to make shure your bearings stay greased if your lucky they aint *****ed by now if they are get new ones its happend on my trike twise. Let me know if that aint the problem.
