The design reuses a motor from an old battery-powered angle grinder, incorporates 3D-printed components (with metal bearing surfaces), and includes a clutch bearing for pedaling when the motor fails. Files available include .step files and a BOM, with a full build video on YouTube. The project is part of a larger cargo bike build. ## Full article daily.dev links to this article rather than hosting it.
