This is a tip you might want to avoid. A chain tensioner is just an easy way to make up for chain and sprocket wear on the slack side and never something you want to put on the power side of a drive train.

If your drive chain gets tight and then loose your sprocket is not true and no tensioner in the world is going to fix THE crucial part of an motorized bicycle drive train, that being the rear sprocket being true on all 3 planes and if you are lucky you never need some POS tensioner at all to keep your drive chain true and tight.
