Derbi Flatreed Pedal Selector Knob

Screws onto the pedal/motor selector on a Derbi flatreed so you can switch between pedal and motor mode (and if you have a one way bearing installed, basically the only way to push it around with the bike off is in pedal mode…)

The nut is integrated into the knob so you can just screw the whole thing on as one piece, no socket/ratchet required.
