My son has got his first proper bike. He had a stroke when he was a baby so one side is a bit weak and one leg is a bit shorter than the other.
I wanted to make him a pedal that offset the leg difference and also that we could fix his foot to to stop it sliding off during use.
The main body of the pedal was 3d printed with bearings pressed in and a counter weight fitted to the bottom to keep it the right way up to help him put his foot on it:

A spindle was machines and flats machined to allow it to be fitted. Luckily it was the RHS pedal that needed changing so I could you a standard rh thread die rather than faffing with single pointing the thread:

Completed pedal without strap - I will post some shots of it in action when my son is next out on his bike!
