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...

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...
