I've been lurking for a few days and appreciate all of the innovation and knowledge in this community.
I've been thinking about electrifying my trail bike (old-school Cannondale Jeykll ), and started working on some plans for it yesterday.
These are the highlights:
I've attached a messy excel spread sheet of basic calculations, estimates, bill of materials, and weights as well as a STEP file (you can use FreeCAD to view) of the unfinished reduction box.
I'd appreciate any thoughts or concerns on this preliminary design.
Calculations and estimates:
