Search results for query: hub motor vs crank

I'm replacing the chainwheel on my Cube Hybrid One ebike which has a Bosch Active line plus motor. I've removed the crank and the locknut now I find there's another small lockring fastening the chainwheel. What tool do I need to remove this lockring? Answers hugely appreciated.

most of my customers are 'traditionally built' anyway. So I have chosen one of the strongest frames, look at the thickness of the toptube. It should cope with 25st riders. One good thing about going with a crank motor is that the stress on the rear spokes are much reduced compared to a rear hub...

Ordered !!

There are a few registers for things like changing voltage 36V/48V, kph/mph, wheel diameter, max Amps, speed limiter etc. How it works: the 5 PAS levels are power levels. It starts quickly. From standstill, you only need to rotate the cranks about 20 degrees, say you push the right crank from 3...

Is this something new ? Do you think there will be a kit version ? What are the pros and cons vs a BBS01 or TSDZ2

If I was converting it, I'd use an AKM 100C/ Q100C motor, a KT 15A controller and whatever battery floats your boat. 36v should be fine if she's not a heavyweight, and 10ah to 12ah to keep the weight down. Any cassette motor is quite wide, but the frame will easily stretch to accomodate it. The...

Hi Everybody, I've been looking at a road bike conversion, but this doesn't seem as straightforward as one might think. My daughter has a Trek Lexa road bike, XS frame size. Thinking that it would help her up the steeper hills around Goudhurst in rural Kent, my son-in-law bought her a...

Hey mate just seen your post with the amount of things you had to replace, how did you go about getting the replacement parts for your voodoo, I need to get a new Bosch CX motor also but I’m having nightmares trying to find one or the “right one” for that matter and rear shock size if you know...

Here are my thoughts. The crank-drive bikes that you mention have not demonstrated good reliability when used in muddy, sandy and wet situations. They're difficult and expensive to repair, though you might be covered under warranty for the first 12 months. You'd have to check with the dealer...

I was unaware of the walk assist as it came with no manual. I'll try it later. I put the bike up on one of those tripod things. No humming or twitching when I pedal. If the motor is bullet proof we are down to the crank sensor or the control unit then...

It's a three phase sensorless motor with a speed sensor. You can't test it bu putting a battery to it. The three bigger pins are the three phase wires and the three thinner ones are for the speed sensor. It's very unlikely there's anything wrong with the motor. They're very robust and even if...

I disconnected both brake sensors but that made no difference. Looks to me like the motor or the control unit but I guess it could still be the crank sensor. The speedometer still works when I ride.

There is no walk assist as far as I'm aware. I have checked the crank sensor and the two brake sensors. All appears clean and operating normally. I will try disconnecting the brake sensors later today. The battery has a healthy voltage (41 fully charged). I'm tempted to test the motor but I see...

Did you remove the plastic disc thing that goes on the disc mount on the wheel? That will set the disc closer to the wheel and might give you room.

I have the 250 watt front wheel fitted to my trike. Opted for this model as I want it road legal and 10 mph is fast enough on a trike belief me. I have read you can keep you existing levers and connect a long armed micro switch to each existing lever and connect them to the existing socket that...

There does appear to be a 400 pounds difference in the two bikes aprt from the forks, cable routing and 3kg in weight they seem to be very similar. And I deffo will not be going derestricted. Thanks Les

Hearing exactly where from is difficult. Check spokes, crank bolt tightening, motor mount tightening, bit of twig caught in the tyre, ...

The Gran Camino has Suntour XCM 100mm fork with remote hydraulic lockout and bolt through 12mm maxle which costs twice as much as the Suntour NEX 63mm on the NCM and about as good sprung coil forks are going to get without going air forks. The Gran Camino has internal cable routing, the NCM...

I will look into getting a price for a conversion kit fitted, I am not prepared for the frustration of getting the conversion wrong myself. My research tells me that the front wheel motor is the worse of the 3 motor positions though

£350 is far from the worst battery cost, and can be a good price for a battery but something like 20ah 48v (960w)with branded quality cells. not 48v 13ah.. (614w) with unknown cells imho.. (watt(hours) = volts x Amp(hours)) But non generic batteries cost more to package and produce so some...
