Default Re: 26 in 6 speed, + motor sprocket... Need one nowww

drive chain gets loose, comes off. garbage chinese chain stretches too much. So yes, running a derailleur bike without a motor side tensioner IS an issue, as you cannot move the rear wheel back to take up the difference. I ran my MTB without a tensioner, chain only stayed right for 10 miles before stretching and jumping. You basically NEED a tensioner on a mountain bike, you cannot move the engine or the wheel.
