Right, that's the point, my 200w is pretty inconsequential if we're talking about a 6-12kw system so it doesn't really matter if I just waste that power out to heat. I just want the exercise and a "natural" feeling riding experience.

In theory maybe possible. Very expensive and you can't combine a schlumpf and a torque sensor, can you? Also, probably dont want to put a ton of power (like 8kw+) through an expensive rohloff.

In that case, you just have cadence sensing, right? Because there's no resistance on the pedals, so there's no torque in the cranks. That would meet my needs if there was some (adjustable) drag on the cranks so that I'd get some exercise and there would be torque to be sensed.

yes. The reason a normal torque sensor won't work is because i can't really couple my pedals to the drivetrain because i would need a full-range gearing allowing me to pedal from 5-40mph in a drivetrain that can take 10kW. That doesn't exist (as far as i know), not at any reasonable price...

I like the idea of this, for application to a much more powerful bike. Did you make any progress with this idea?

I'm very interested in the same question as Charles asked in the original post. I'm not sure, but I think the reason he's asking maybe similar to my reason. It's not about providing any meaningful amount of energy via my pedaling, it's more about using a natural, bicycle-like experience as a...

Thank you, I've done some searching but haven't found a lot, I'll check these out.

I'd like to make a light electric motorcycle somewhere in the 4 to 12 KW range and I want it to have pedals with torque and Cadence sensing. But there's really no reason at that power level to have the pedals integrated into the drivetrain. My power input would be trivial compared to the motor...

YES! I'm looking for the same, AND i want it to be quiet. A sur ron or any other high-rpm mid drive seems too loud. I think maybe a 72v BBSHD would work for me except I can't have torque-sensing with that can I? I saw a full-size electric motorcycle (street bike) that had pedals that were not...

Wow, the Frey seems like a very interesting bike, but this is such a long thread. Is there any summary or synopsis? or a few particular sections to be sure to read? There are so many good threads and good info on this (and other) forums, but i can't read it all and I don't know how to...

This page may be helpful: https://www.ebikes.ca/product-info/advanced-pas-kits.html#torque-sensors I love the idea of a torque-sensing PAS that works really well, but i have no patience for one that doesn't work well or isn't well-refined and tuned. I'm on the hunt for a good setup but don't...

Did this e-moto-ped get built? Looks like a lot of the money was spent and the project was started. I'm curious to hear how it turned out! Also, did you ever have a gas engine in the bike? If so, how did that compare to the electric?

I just picked up one of these bikes, used, from craigslist. I like it pretty well but the battery seems to be pretty weak. I test rode the bike around the seller's neighborhood and it seemed fine with only my own weight on flat streets. However, when i got it home, put my large Yuba Baguette...

Hi Marty, i want to do something similar, did you ever figure this out?

I think it's really not that complicated. Get a geared motor rated 500w or more, put it on the back, and love having an ebike. Having the motor in the front wheel will not cause it to spin unless you're on a VERY low traction surface or you're running 2000w of power. But, it makes the steering...
