motor

Hi everybody I have a Shengyi dgw07-20j motor on my shitty MOMA ebike. I had an error 03 "hall sensors" on my KT LCD5 display Motor works very very badly, slowly and vibrates like hell . After disassembling it, I noticed that one of the two capacitors was gone from pcb (bad welding?) I must...

I've seen some nice motor cassettes for wheels and I guess you build your own wheel from them? Not seen any rims for sale yet. How difficult is it to build a wheel and is it a good option? I'm thinking about having ago for interest.

Hello all, this is my first post on this forum, I'm excited to join this friendly and welcoming community! A friend of mine sold me an eBike with the a 36v Voilamart 500W rear (Brushless Gearless) motor. It is around 3 years old and had been running fine with me over the last few days of having...

Hi I recently got a new e-bike, and just recently noticed that the motor is making a lot of noise when pedalling backwards. I don't know if it is normal for this motor to sound like this, or i should contact Yamaha through my Local Bike Shop? Anyone else who have had this issue, if so, how did...

Hello Folks just want to hear your opinion. I bought 750 w motor and it s very nice. Silent and powerful. If you have 20 degrees hills it s perfect. If you want on mountain, you better buy 1500 w. Maximum speed it's around 40 km/h. How to increase my speed even more? With this kit I got around...

Hey peeps! I have this Ebco UCL20 (Black), and I have had to change the motor. I have one rear wheel geared motor attached to my Ibex Byocycle (White) and a 36v 250w front hub motors. ( BAFANG - FM G020 250 D09 ) However when I attach the front wheel to my Ebco, it pulses once to initiate...

I tried to search for this but couldn't find a thread about it. Does anyone know if an 11-Speed MTB cassette fits on a Bafang G020.500.DC (BFSWX02 48V 500W) rear hub motor? I know 7/8/9/10/11 speed MTB do all use the same freehub body, but I ask because I know 11-Speed MTB cassettes have a...

Hello everyone, I wanted to make my first electric bike. I decided to buy a conversion kit and go for 500w 36V engine. However, I am not sure if the battery I would like to buy (52V) will work with this motor. The motor I'd like to buy is this one (front): https://amzn.to/2INRNj3 And that's the...

Years ago I bought a second hand e-bike in pretty bad mechanical condition for dirt cheap. I did all the repairs and it's been running mostly fine all this time, except for intermittent waterproofing issues, specially during the winter. Unfortunately a few weeks ago the LED display finally died...

Okay so... was riding home from uni when all of a sudden the bike felt very heavy, straight away I could tell the motor wasn't running. So I pulled the throttle assuming perhaps it was the PA (Had problems in the past with the magnet disk) and it was working but was feeling very jittery and...

I am looking for a second hand Ezee Forza, or just the motor including the front wheel and the control unit.

If we imagine a road that has a steady incline of say 10% or thereabouts, for many miles, would a hub motor tend to become less powerful as it (presumably) heats up, and would it eventually grind to a halt before the battery is flat?
