Hi all, 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 (agni 95R), controller, MBB, BMS, etc.), a 4kW general generator (6.5 peak), custom made aluminum 72 tooth rear sprocket, 13-17 tooth front sprockets, custom chain tensioner, 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 approximately 10 years old and 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 (and likely remove the generator) 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 (not currently interesting in parting it out piece by piece). I also have plenty of pictures they are too large to share on this post but happy to share if interested. Anyways, let me know if interested!

Keep building and enjoying friends!

That’s an interesting idea I may just try that. The bike doesn’t have regen so nothing there

I would guess that the extra kW was consumed while in Float. It can also be the age of the cells, being they are at 80% now there should also be a charge efficiency hit.

The bike consumed just over 2kW while new it had 3.7 so that means my batteries are down to about 54% even. Does it make sense though to use a whole extra kW (50% extra)? That seems like soooo much to blame on the charger, degraded battery and circuit balances. But I’m not sure

First of all good for you! Just because other people haven't done it doesn't mean that you can't. I would say first that the real question is what do you want to get out of this bike and why a hybrid vs. full electric. from there you can start to make sense of your project and what range you need/want. From there of course you can start looking at motor, engine, and battery sizes. Chances are if you are expecting amazing range and performance the bike will be quite expensive and heavy, however if you just want to learn or would like a modest city bike I think this would be a fun project for you.

Here's a video showing how I changed the front pulley on my 2011 Zero S.



Still don't know how to calibrate the speedometer. Right now I just remember that my it shows 12% faster than my actual speed.

Is it a 3/4 Shaft for the motor or 19MM (2 thousands of an inch smaller than 19mm) everything I am seeing shows 19mm but your video you say you used 3/4 hub sized pulley. Please let me know asap.

Did you figure anything out? I took apart my battery and after a couple months am putting it all back together. when connecting the BMS I get the 5-3 Beep code too not sure what it is...

OK this project is back on. I can get a Meanwell RSP-2000 but would my bike be capable of taking 2 wired in parallel? this would be a 1C charge rate for the battery...

Hi guys,

I've finally finished drawing the schematics. Enjoy! 

This Diagram is fantastic thanks for making it! I have a question regarding the charger input connection... Red = Positive, Black = Negative, Green = charger detected, however what is the white wire? I know it says charge but what is its function? I am working on a 2010 project and am trying to make it capable of 2 quiq Q 1000w chargers. I am going to use thicker gauge wiring for the positive and negative cables and more resistant connection where the Black connects to the 3 others, however I am unsure what to do with the white. If anyone could let me know the function that would be greatly appreciated
