Hydraulic drive bike???
First post here, I was sitting here wondering, I wanted to motorize my bicycle in some way, gas or electric not sure yet, but was trying to come up with a decent drive system. And I thought, what about hydraulic drive? Then I can have the motor anywhere and it would just rotate some power steering vane pump, and pick up some hydraulic motor and mount it either on the front or rear wheel and route some houses and it would work pretty sweet don't you think?
Anyone attempted this? Hydraulic energy transfer is pretty efficient, better than chain even, so it could work, it would just weigh a few pounts more.
What do you all think?
