Bought two Ridgeyard tricycles from China and am fitting electric motors to both. Was hoping to use largest Shimano cassette cog on trike as drive to motor but am having problem matching a small cog at motor end. Anyone done the same or have constructive comments? Thanks Ian Rees.

Some pics of the motor drive end may help to suggest a sprocket fitting.

Thanks for your reply. I currently have a motor which came with two sprockets held on by a 10mm nut. Unfortunately the sprockets do not match the Shimano chain. Currently I am in the process of reducing the bore of a 10T standard sprocket to fit the shaft using a heavy washer of the correct size. Not elegant but it should allow me to fit a chain to match the Trike. Ian
