Search results for query: hub motor vs crank

With a crank motor, you can use the gears to keep the motor running at the rpm that you based your calculation on, but you can't do that with a hub motor. How will your controller know what torque there is at the crank?

For a hub motor I'd measure it by telling the controller all about the motor, and letting it make a calculation from easily measured input V and I. For a torque sensored mid-drive, it already knows from torque and rpm of the crank, so just needs a reasonable allowance for drivetrain efficiency...

You haven't said if your Yose 350w motor is a freewheel or freehub (cassette). The freewheel version number should start with AKM95RS....... and the cassette version AKM95RX...... - They are geared differently. The Yose UK website lists clutch and gear assemblies for both versions, although...

Remove the screws, then the side-plate lifts off, assuming that you removed any nuts from the axle. You can leave the cassette or freewheel in place as long as you can reach the screws, otherwise you have remove the cassette or freewheel to get to them.

I have 6 cross head screws which look as though they are stainless. Does that determine which motor I have and from that can I order a new clutch ? All the ones I have seen say 36 teeth but no info specific to Yose so maybe they are pretty universal. As is so often the way I went out to my shed...

My mind likes standout numbers, like a round thousand, ten thousand and so on. Yesterday as I nearly missed a train, my Shimano E5000 Ridgeback X2 passed 33,333km. I knew you'd be thrilled, too. But it nearly didn't get there. About 100 miles ago, over a couple of short shopping trips, the...

Hi all, I have a Raleigh Stow-e-way and overall it's been a good bike, but now I'm starting to have some issues with the electrics. The display has been cutting out recently and I found taking the battery out and slapping it back in would fix it. However, this doesn't work anymore. My display...

The slower the motor turns, the more current it draws, so any connection or battery issues happen at low speed, not high speed.

Yes it does sound like a similar problem but it happens even when i am going slow and pedaling up a hill i think it’s something to do with the actual motor underneath the frame. Whatever makes the motor spin/crank i think is broken or has to much slack and needs tightening. but no bike shops...

Yep - If it was me, I would try a new battery with that controller, if that didn't work, then buy a matching controller/display/ pedal sensor There is lots of options for 36V batteries - bag battery for lightest weight , rack battery if you have rack mounting points, seat post battery, bottle...

there is no current display! i just hook up the battery and turn the battery on for it to work. There is a pedal sensor and thats it. the controller has only 3 wires out of it, 1 9 PIN cable for the motor, 1 x to the battery, 1 to the crank / pedal sensor. No display, no brake cutoff or any...

I got an Carrera Crossfuse E bike (2018) (36v), Motor: Bosch Active Line Plus BOU350 Crank motor and a Purion Display with MicroUsb Service Port At the moment the Bike doesn’t switch on, even so the Battery is full... when I press the test/on Button on the Battery, the Purion Display...

If I owned a crank-drive bike I would be offended by your generalisation. Presumably you aren't bothered about offending all those members of the forum who own crank-drive bikes?

A madman always believes that it's everyone else who's mad. If you want to test yourself to see if you're nuts, two of the first signs of madness are watching or listening to the BBC, and reading The Guardian. The next sign is having any hairs growing on the palms of your hands. If you're...

What are you using to generate these graphs, I would like to see some of mine in this format.

A 'flight data recorder' monitoring voltage and current at the motor, rpm, and motor temperature inside and out for that hill would answer many people's questions! In particular the data for that steep bit.

Yes - but I was thinking about the traction and handling issue in a more powerful FRONT hub motor. Cheers.

Yep crank drive motor would work, also rear hub motor would work, just would need enough power. I am 105 kg and use my rear hub up long steep hills,. I slightly prefer my rear hub to my mid drive on roads / light trails, find it a more relaxing ride. I think where crank drives come into...
