bought a new rear wheel:
i have finally chosen 420 chain and sprockets for this bike so i've bought a new small sprocket and got a new aluminium rear sprocket from waterjet:
comparison of the sprockets, old one made of steel:
after installing of the rear wheel we've found that the rear sprocket's plane is pretty far from the frame:
it seems that we need to shift a motor for approx 20 mm to the right side but we decided to make long shaft as a temporary solution:
and welded small sprocket to it:
