Hee he hee!
There's no chain! It's a drive-shaft motorcycle! It will be able to handle whatever the batteries give it!!!!
Since the controller can handle UP TO 144V, we could use whatever combination of batteries we want - 4 big ones would be typical. We do have a secret stash of smaller 12v batteries. I think they are 18ah each. Each of those batteries is roughly 1/3 the size of the 4 batteries that are in the cycle right now, so we COULD theoretically run it at 144V.
I think the issue if we did do that is HOW TO CHARGE the cycle. 144V chargers aren't cheap, but neither is a dozen 12v chargers. A 144V system might need an off-board charger.
