Parts I required when I converted my bicycle into a EBike. The holder for the pedometer sensor was required as the original was to small for my bottom bracket.
The other parts are just either mounting support or covers
Parts constructed with ThinkerCad

All parts uncritical, printed with either 0.25 or 0.35mm resolution. The ring of the pedometer sensor is made with low resolution that the optimal fit can easy be achieved by a bit sanding
