if this can be made lo-tech, without any software and hi-tech gadgetry, then it's a killer.. even if 10-20% less efficient. Most people don't need racing.. It won't need any gears and switching them anymore, as electrical motors have mostly same torque on whole range ; The force of pushing pedals does not need to match the uphill - as long there's something in battery ; And one can keep pushing downhill regardless of speed, and that energy will not be wasted..
- vestrigi 5y agoI’ve been thinking about how this could be retrofitted to an existing frame. The generator is too big but it could be mounted in front of the crank shaft under the frame and then be connected via simple gears or a short chain. This would still have said benefits. I think the possibility to choose when to save energy and when to put it out you mentioned is possible with a conventional e bike but not all bikes support this due to legislation.
- svilen_dobrev 5y agoif the generator can be made thinner, to be put instead of the 2-or-3 pedaled gearwheels (5-7cm?), would be fine. And Can be quite larger diameter, and any shape, it won't rotate
- AtlasBarfed 5y agoThe racers (pure bikers) won't be interested in battery assist either. For the vast array of use cases that ev bikes enable (basically, go to the Netherlands for all the things they do with bikes) for decarbonized, fun, short trips, this eliminates a vast amount of headaches. This drivetrain has regen braking, a vastly simplified consumer experience, and MIGHT enable solving the other #1 problem with bikes: security. You can effectively lock the motor with a chip and an app inside a frame so it won't go anywhere, and even stealing it in a van and hauling it elsewhere to get it working isn't worth it.
