PEDALS

Pedals are made of stainless steel 12 mm stick bended by local locksmith.

We mount it on the chassis with two pieces of steel 40x5 mm (U), where we drilled a 12 mm hole.

To make chain running parallel with the front gear, move the right side of pedals a little back (d2 > d1), so there is a right-angle between the pedals and the longitudinal profile (A). You will have to file holes in (U) because of it.

Use some lock washers between pedals and (U) to prevent moving pedals left-right.
