<i>only about 60% efficient...</i> That's lower than I'd expected, but still, I don't want to choose a primary drive system that's down on efficiency, just so that I can have better regen. Maybe I can come up with a front-wheel system that <i>only</i> operates during braking (to drive the...

Gear pumps are only 75-90% volumetrically efficient. That doesn't sound so good...even assuming 90%, I'd be at 81% overall for going electric->hydraulic pump->hydraulic motor. The motor itself is probably no better than 95% or so. I suppose I'll have to go with chain and only the regen I get...

Thanks, I know that Yamaha was experimenting with 2WD on the road racers (those engines make more power than you can put down through the rear tire, so this was a way to use more of it). They had a hydraulic system to the front wheel, too. I may end up putting together a test system, just to...

I am looking into using a hydraulic drive system in an electric motorcycle. My reason for doing this is that most braking force on a bike is in the front wheel, so that's the place to recover energy in a regenerative system. However, because of the way the front wheel must move, it's difficult...
