Here's what I'd do. Open the controller, switch everything on, then test the voltage where the white motor wire is soldered while you spin the wheel. If you get one pulse on or off with 5v per rotation, you have a speed sensor in the motor, but the controller settings aren't picking it up. In...

There's a new regime at Oxygen now. John Camm, the previous owner sold the business a couple of years ago. He carried on for a bit as ome sort of adviser, but he then got a brain tumour, which he died from very recently. Dale left and went with his wife to Northern Ireland. The last guy I saw in...

Superglue should be OK. When I did my mechanical engineering degree, we used to glue strain gauges to metal with superglue (then called cyanoacrylate) to measure stresses. I think you can still get new replacement torque sensors from KTM.

You should change to 48v at the same time as upgrading the motor because you get 30% more torque for the same current. A 48v 201 rpm Bafang BPM will be perfect for what you want. 22 amps should be enough, or 25 amps for ultimate climbing. If you run at 36v, you'll need 30 amps, which means...

Those hall sensors should work fine.

It doesn't matter who unearthed it. it's what's in it it that counts, and it's an official EU publication.

You have to ask Cyclotricity, if that's where you bought it from.

The white wire is the ninth wire in the 9-pin connector. If your motor has a speed sensor, the signal is carried by that wire. if it's a DD motor, the controller can pick up the signal from one of the hall sensors. There is usually a setting in the LCD for how many pulses per revolution to set...

PAS = pedal assist sensor EABS = electronically assisted braking system Search the forum using Google for my posts on the self-learning procedure to save my typing fingers.

You haven't shown what you have and what you've done, so how can anyone help. Logically, you need a speed sensor connected to the white wire.

Black grey and red is EABs for direct drive motors. You need to connect a speed sensor of some sort to the white wire for the LCD to show your speed. You have to do the self-learning procedure correctly before the motor will work right. Red black and blue is PAS. You seem to have something weird...

What are you using as a speed sensor?

There's the same chance of your laptop or tablet catching fire and a lot more chance of your phone flaming out. Do you worry about them too?

Any controller should work. Most people go for the Brainpower controller plus S66 LCD at around £40 or the nicer KT 15 amp Sinewave controller with LCD3 from Topbikekit or Elifebike at around £70. Whichever you get, it's probably best to get a new throttle, 8 or 10 pole PAS and speed sensor...

There's not much you can do with that. probably time for an external controller.

It's either because you haven't set P2 to 1 or you don't have a speed sensor in your motor, in which case you need to fit an external sensor. With P2=0, it picks up the speed signal from the motor halls. When the motor stops, your speed signal will stop too. P2=1 means it picks up the speed...

Did anybody read this? https://www.zerohedge.com/political/bizarre-eu-funded-comic-book-predicted-pandemic-globalists-saviours

They have UK agents - Leon Cycles https://leoncycle.co.uk/?gclid=CjwKCAjw0_T4BRBlEiwAwoEiAYgtzUQ8jN2FX270bmQtYSXkkM2ac4mdO56KQOA9DVx29RDU5P5xwxoCz70QAvD_BwE All the parts are standard Chinese. It's just that they probably reverse some of the connectors. You can always buy the parts on...

If you go for a rear hub-motor, you need a cassette motor, and it's ideal speed would be 260 rpm. Most ready-made 20" electric bikes would use motors with around 330 rpm. A 201 rpm 36v motor becomes a 260 rpm one when you run it at 48v. At 48v, you get 30% more torque available, so I would...

How many speeds are there on the rear cassette? This is important to determine the right kind of motor. Also, how fast do you want it to go - modal speed and max speed? This is also very important for choosing the right motor. The legal limit of assistance is 15.5 mph, but to get good power at...
