I ended up building a "hybrid" motorcycle back in 2019 as part of a school project. I put "hybrid" in quotations since I was not able to engineer the bike to run on the ICE while also battery. This bike will run full electric till depleted and then park, the generator turns on an recharges the bike. I realize this is a bit counter productive. Ideally it would be able to use battery until depleted and then the ICE generator would be able to run and power the bike (while staying mobile). My bike was not designed to that level of engineering but holds the principles that it could be accomplished with some additional systems. Anyways, I ended up using a 2010 Triumph America chassis, the electronics from a 2010 Zero S (batteries, motor, controller, etc.), a 4kW generac generator, custom made aluminum 72 tooth rear sprocket, cycle analyst, the Zero's Delta q charger, and a Meanwell RSP 3000 (Which I didn't end up using). With a 17 tooth front sprocket it ended up reaching a top speed of 81km/h. In total, it travelled 22.24km, at an average of 57.43 km/h and consumed 1891.5Wh. While maintaining 80km/h, the motor required 6338W and consumed 79.17Wh/km. These batteries unfortunately were tired and so only at about approximately 50% their original capacity.
This was a very fun project, I learned a lot, and was a really fun bike to ride! Unfortunately the bike has sat since, and now the battery pack has low voltage and not accepting a charge. It would be a really cool project to throw some leaf packs or newer technology into the bike but for now I do not have the time or money to do so. If anyone locally is interested in seeing it or purchasing the bike (for parts or upgrade) I'd be more than happy to connect. I also have plenty of pictures etc. happy to share.
Keep building and enjoying friends!
