Search results for query: hub motor vs crank

Isn't this the situation where a crank motor excels? Steep hills, substantial rider, front hub motor not coping? The crank drive motor doesn't suffer from the lowering of efficiency the hub motor is experiencing as it is slowed beyond its ideal motor speed. With a crank drive motor, you just...

In that case you can check its function with a meter. IIRC, black and red are 5v power, and the two others (assuming that yours is the 4-wire version) are one pulsing 5v when the pedal turn and the other variable voltage between 0-5v depending on how hard you twist the crank. I'm pretty sure...

What do you mean by "looks good"? Did you take it off and inspect it. Did you look at the light sensors inside to see if they're clean? Did you check at both ends that the wires haven't been pulled?

Hi all, Carrera vengeance 2.0 owner here (not by choice, it was a gift). I've managed to solve all problems I've had with the bike in the 2 years I've had it so far but this one as got me stumped. There is no assist coming from the motor at all. There's no error codes showing, walk assist is...

1. i do as i normally just fit a new tube, chuck the old one in my bag and repair it when i get home so its ready to re fit when i get the next puncture 2. Ive been using Marathon Plus and Durano Plus on my commuter and road bike for nearly 15 years (been commuting for 17 years) you can still...

TSDZ2 is OK for relaxed cycling, like a ride in the country, but it's very slow compared with a hub motor. If you want 20 mph, a TSDZ8 would be better, but even then, a hub motor would beat it for reliability, dependability, cost, comfort and convenience. I think you'd die of boredom using a...

A crank motor doesn't have any fixed amount of torque. The torque at the back wheel is all that matters, and that depends on your gearing and how much power comes out of the motor. Hub-motor torque does not depend on the gearing; however, the torque is directly proportional to the current, and...

It's not that difficult to convert most bikes to electric. You can get a nice powerful kit from Woosh for about £650 (48v TSDZ8) that can be fitted in an afternoon. If you want to go that route, show some photos of your bike which show the detail around the bottom bracket on both sides and the...

my introduction to ebikes was with a second hand Specialised bike, converted with a 250 watt Bafang crank motor - the BBS01. It cost me a shade under £1100 with the conversion done. It has good hydraulic brakes. I have never regretted buying it and have done about 3000 miles on it. The...

At the cheap end, something like this would do. At 105kg, you need 48v for the extra torque...

Likely a silly idea but... ...fit smaller carbon fibre wheels for less weight and more torque where tyre meets tarmac? 24" perhaps? If watts and torque were proportional, the legal 720W motor driving my 20" rear wheel is 885.6W, compared to a 26", because my 20" wheel has a 23% torque...

your back!

I have ridden mine 434 miles so far and having swapped out the brake calipers for hydraulic cable operated ones ( as researched and detailed by Saneagle) I have no complaints at all about it - albeit that it is not a speed machine having only 8 amps @ 36 volts max power input to the motor. This...

You know what you are doing, and are very generous with you time to help others know too. I sort of know what I'm doing (be it building a PC or installing a conversion kit (***)). However, I do know that many people are very far from being brave enough to do any of this (even though capable)...

That's what crank motor kits are for. Why else would anyone fit one?

I volunteer at a charity recycling donated bikes which are fully serviced for resale. A few ebikes are donated which usually have dead batteries, no key etc so end up going for scrap afted stripping any usable non E parts. All of the bikes have been purpose built as Ebikes and with batteries...

It is an integral sensor as in your picture, and I can see it is turning correctly. I have been watching several you tube features which seem to suggest the odometer display comes from magnets in the motor hub itself rather than the pas sensor. Maybe I need to be investigating there. From my...

If an all in one sensor And your bikes crank axle is a shade wider in diameter than the expected 17mm the sensor can 'catch' and turn until the cable is pulled taught, this can result in a very inconsistent motor engagement.. (the problem i had.. if a 2 piece with a separate magnet disk...

Thankyou for your helpful reply. I've decided I will send it off to the ebikemotorcentre who get very high recommendations on here

The mode of failure goes something like this: Thr crank seal wears and let's in a bit of water. The water gets into the bearing and damages it. The excessive play in the bearing damages the seal further and let's more water into the motor. From there the water can get into the electronics or the...
