Technical problem with a 20 inch 48V 1000W bike kit – problem solved

Posted by on April 5, 2025 No comments

Today I hit in a technical problem with the 20inch 48V 1000W bike conversion kit (Item ID:#LBCK20481000FN). I was riding for a shorter distance steep uphill in level 5 and suddenly the bike motor was making an obscure humming sound and was vibrating very strong. So I stopped immediately and shut down the system. I checked the hub motor and the cable for overheating but they where just with normal temperature. After a while, I already turned to go back downhill, I started the system again but the problem still exists. It seems that it is maybe a problem with the controller because now there is no reaction in changing the power level (1-5) or turning the throttle on. The hub motor gets only around 10 Amps with a max. of 590W (measured with a installed Amp/Volt meter in between). When starting pedaling or with the throttle with low speed the vibrations are immense but when I gain more speed the vibrations are reducing to a lower level but they are still there. When staying still and pull the throttle full, so the tire normally can spin free, only the vibrations and a loud humming sound exists. I know I do not have any warranty more leftover on this system but maybe you have an idea how I can repair this for a budget price.

I already solved the bike conversion kit system problem.
Funny what unexpected small things could cause some different technical reactions. The problem of the bike conversion kit problem above was, that one of the 3 phase cables to the motor was broken. By the effect of the depicted problems above I really thought that something in the controller was burnt-out but happily I could find the broken cable very soon so now everything
works fine again.

Buy an electric hub motor kit

Posted by on April 5, 2025 No comments

I’m very interested in buying an electric bike kit as soon as possible for my bicycle (26 inch rim )and I found your page but I would like to know about all the models you’ve got from the smallest to the biggest and strongest ;and THE PRICES of these and all the specifications:
speed (km/h)
torque
durability
distance of charge
weight (of the electric bike kit)
weight (it can carry)
does it come with battery what type of battery (lithium ,lead)
voltage
amperage
watts
rims what type of rim

I’m not really interested in the rim (inch)but some info would be good ,I want to find out about these brushless hub motor

I need something that lasts 70 km and runs at 60 km/h on a flat surface with lots of power like to move 150-180kg of weight (bicycle me, hub motor, and a little extra weight)

what does the electric bike kit include?:hub motor battery controller throttle, brake lever, pedal sensor BATTERY MEASURE etc.

and what combinations can the electric bike kit fit 36v – 48v – 24v -6,7,8,9,10 amps if possible

the same for the rear motor and for the front hub motor

(front rear) sizes, types ,performances PRICES and everything they can do the thing is that I live in wide mountains so I need something strong but lasting for I live far away of the city.
