Regen Braking and Electric Bicycles, Justin's Presentation from 2022 BC Bike Show

On March 5th 2022, Justin gave a talk at the BC bike show about regenerative braking as it pertains to the world of electric bicycles. Regen is an important topic that's been largely misrepresented by the ebike industry due to the focus on mid-drive and freewheeling hub motors, so we wanted to set the record straight on many areas.

This follows some of our original research on regen which we posted on this Endless-Sphere thread many years ago:
