    MXUS New 60V 1200W Geared Hub 120N.m Torque GDR-19FAT

    any new info? This motor seems interesting. If it is underrated to the same degree as many DD hub motors, this could be an exciting motor.

    Pedaling at high speeds - Hub motors compatible with wide range casettes

    Leafbike might be a good choice thanks! I was looking at that but didn't see that it is available with a freewheel. Also wasn't looking at the RH212. More torque and less-high speed IS what i'm after, so that might be a better choice. Thanks for the specific tips! are there any geared hub...

    Pedaling at high speeds - Hub motors compatible with wide range casettes

    What motor will accept one and is powerful enough to get to 40mph?

    Pedaling at high speeds - Hub motors compatible with wide range casettes

    😁 so, back to square one (or question 2) Are there any hub motors powerful enough to do this, and that will accept a modern wide-range mt bike cassette (preferably SRAM XD)? OR a wide-ratio freewheel, 11-5X

    Pedaling at high speeds - Hub motors compatible with wide range casettes

    I would prefer not to have a 2x or 3x setup with multiple front rings. Not worried about aero, just want the experience of pedaling. 9 spd with 11-48 would probably be good enough. Which motors will accept that? Anything that can reliably get me the speeds i'm after? The other thing i'd...

    Pedaling at high speeds - Hub motors compatible with wide range casettes

    Good points/questions. I think I want to stick with 24 or 26-in tires. Or maybe 18 or 19 inch motorcycle or scooter tires. But remember I still want to be able to Pedal comfortably at 10 mph also. So regardless of tire size I need a pretty wide range of Gears available for pedaling. Not quite...

    Pedaling at high speeds - Hub motors compatible with wide range casettes

    I'd like to build myself something of a moped. Think of a sturdy cargo bike, or upgraded version of something like a Super 73 style. I want to be able to go about 40mph or so. I like to pedal and i'd like to use a torque-sensing bottom bracket and cycle analyst to implement pedal assist that...

    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...
