The
Grin Tech all-axle ebike motor is made in Vancouver where Grin also assemble their modular
LiGo battery pack using LG MG1 cells but I'm unsure if the cells are manufactured in LG Chem's Holland, MI, plant, or from where they source the BMS. Grin designed or modified Infineon controllers, the Cycle Analyst computer, and Cycle Satiator battery charger, and those are made in Asian factories. The eVox Dyname motor was
developed in Quebec by Procycle, eVox ebikes are assembled in Quebec but I'm unsure if the motors and frames are themselves made in Canada and the Dyname motor isn't available as a kit. Prodecotech have a final assembly line in Florida but use imported frames, components, and motor/battery parts. As J.R. mentioned above companies like Pedego and Trek do in-house design in the US but the bikes and components are imported. Endless Sphere has a list of
failed EV companies including several North American ebike component manufacturers to which can now be added the Canadian arm of Bionx. Here is a recent but incomplete list of world
electric motor and battery manufacturers. In addition to those on the list
Astroflight manufacture brushless electric motors for remote control vehicle and aerial drone applications in Irvine, CA, a small number of
DIY enthusiasts have used reduction gearboxes with these fast spinning motors on ebikes. Electric Motorcycle motors and battery packs are manufactured in the USA by Zero, Alta, Lightning, and Harley are partnering with Alta to launch an electric motorcycle line, but none are building ebikes. I'm unsure what other US or Canadian made battery cells, BMS boards, controllers, displays, wiring harnesses, bicycle components etc. are available, other than a few ebike specific parts made in small machine shops like Luna. There are several US steel frame builders and you could DIY assemble a somewhat made in North America ebike albeit many of the components will be imported.
