    Pedal generator for lightweight car with all electric drive

    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.

    Pedal generator for lightweight car with all electric drive

    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.

    Pedal generator for lightweight car with all electric drive

    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.

    Pedal generator for lightweight car with all electric drive

    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...

    Rear Gear Generator

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

    Pedal generator for lightweight car with all electric drive

    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...

    Motorcycle with Pedal assist

    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...

    Building an EEB with a QS 205... Help needed

    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...

    My Bafang Ultra Mountain Bike! Frey AM1000

    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...

    E Bike Kit with torque sensor like Yamaha Bosch etc

    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...

    Electric Motoped - Advice Needed

    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?

    Motiv eCruiser 48v review

    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...

    Long Tail Geared Front Hub

    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...

    Pole Count and Reduction Ratio for Q128H hub motor

    Does anyone know the pole count and gear reduction ratio for the Q128H rear hub motor? I'm setting up my S-LCD3 unit and need that info to get the speedometer reading correctly. I will email BMSbattery to ask the same question but i thought a post here would be helpful for anyone else who may...

    Ezee geared hub motor - slipping?

    Sorry, I have kind of moved on to other tasks in life... maybe getting back to this soon. It's been snowy/icy/dark/cold here so i haven't been riding. The old controller is an infineon 12 fet with CAv3. The controller will pull a lot of current if i let it, I think around 40A? I pay more...

    20" vs 26" bike wheel, what's best?

    I built a 20" wheeled cargo bike for a lot of very logical reasons. I don't like it very much because it rides too rough.

    Ezee geared hub motor - slipping?

    Update, the motor still works fine with the old controller! I would have bet good money that the problem was mechanical, but it seems that it must have been electrical. I haven't solved it, but it doesn't matter because im going to keep the old controller with this motor and ive got a couple...

    Lubricating the DNP Epoch freewheels

    to be clear, the sound that's loud on mine isn't ratcheting of the pawls, like the clicking/buzzing that is particularly loud on some high end hubs like Chris King. What i'm hearing is a loud whirring noise, like that of a slightly rough or poor quality bearing. Not gritty, not clicky, just...

    Ezee geared hub motor - slipping?

    Thanks for the feedback. I guess one thing i could do is plug it back in to the old controller and see if anything is different. If that doesn't solve the problem, i'll open it up again and check the hall wires as mentioned. This motor was one that I scrounged up cheap by putting together...

    Ezee geared hub motor - slipping?

    It had been working fine for a year until i installed this new controller. Could something in that process have caused it to stop locking when it should?

    Lubricating the DNP Epoch freewheels

    My DNP freewheel is very loud while coasting. It's not gritty or terrible sounding, but just loud and i'd rather not hear it. I'll have to give this oiling a try. Anybody have a technique that has really quieted down their DNP? I'm particularly interested right now because i'm getting ready...
