  1. As far as I know every bike does this. Loosen the rear axel nuts enough to have movement, pull the wheel back from the dropouts and feel the chain with your finger as you spin the cranks, you’ll find that there’s a “sweet spot” where the cranks have a tighter pull on a certain position of the cranks, adjust the tension from that position. Idk if that makes sense I’m drunk.

    Something is crooked. Likely your sprocket alignment. The reason it goes limp and then tight is because at the crooked point its closer (loose) and at standard point its tight.. because it isn’t aligned so a full rotation will cause different distance from sprocket tooth to flywheel tooth. Usually this is fixed by adding a spacer on either side of sprocket/BB. And making sure rear wheel is properly aligned in drop outs. Either can cause this..

    Back wheel is either not straight.. or sprocket isn’t straight… lastly your sprocket can be bent. (Less likely and would be visable).
