This kit contains the Assembled 3D Printed AND Hardware parts needed to build the award winning “Bicycle BoosterPack MINI” as seen on &

This kit contains 52 total parts (29 unique parts as listed), with is everything you need to build a mini boosterpack aside from the electronics which are not included. Please see my video series & instructables for details on electronics.

The Bicycle BoosterPack Mini is device designed to clamp on to most bikes to provide an electric boost via a friction drive system. The parts in this kit are custom designed and 3D printed with high infill on a professional Witbox 2 out of black PLA material. All parts are assembled (as much as they can be minus the electronics) and then coated with a UV resistant protective clear coating.

If you own a 3D printer, the associated 3D Printable STL files can be purchased separately on

The complete list of required electronics can be purchased from 3rd party suppliers. No engineering required, I recommend exactly what you need in the BOM in the Instructable.

NOTE: The BoosterPack mini is designed with a universal motor mount, so it will fit the 50mm or the 60mm outrunner motor. The FAN, however, is still a motor specific size so please send me a message specifying which size motor you intend to use. (The default recommended size is 50mm).
