Hello everyone I decided to get back in to the E-bike hobby and am in the process of designing my next build. My question is does anyone know if its possible to buy a similar BMS as the one that comes with the new Stealth B-52 E-bikes? That thing looks just amazing!

Hello everyone I have decided to come back to the e-bike world after getting continually harassed by police on my gas powered bike. I was just wondering if anyone had any experience with the chinese lipo cells that they advertise on sites like Alibaba etc. My idea was to buy some lipo pouch...

I was just wondering if anyone knows what the default settings are for a 12fet Lyen controller? I am going to be using one on my Gio scooter which has a 60V lead acid battery and an 800W hubmotor.

If its a newer crystalyte sensorless controller then I dont think you can wire the cycle analyst to it. Justins instructions are for the older controllers. I couldnt get mine to work. If you get a cycle analyst with a speedo magnet in the wheel then it will work. I think that Crystalyte did...

The thing that screws me is the fact that I live on one hell of a hill! That is the whole reason why I got into e-bikes, you really wouldnt wanna pedal up this beast! The Gio scooter just barely made it up! I tried it when it was 48V with no shunt and I had to push it up one part.

I have been into e-bikes for over 4 years now and I think that the longest stretch of problem free riding has been like 1 month! I realize that when you run 72V and higher the bikes become a little bit unreliable. I went out and bought one of those Gio 800W scooters because I wanted something...

Yeah its pretty rediculous the claims some of these dealers make in an attempt to sell their products. When I bought my Gio scooter the guy claimed that it would do 70km on the 48V20Ah Lead acid battery. I live on a steep hill and I only get 22km out of a charge! Thats a little bit less than...

I cant figure this thing out! Now it just makes noise but doesnt move. I checked the halls with a Lyen tester and it says they are good. I checked the phase wires and it says they are also good. I checked the controller with his tester and it spins the circle on the tester fine. I cant...

I have an issue with either the controller or motor on my e-scooter. Sometimes when Im riding and I stop, when I go to go again and I twist the throttle I get nothing. I have to turn the key off then on for it to work. When I am testing the scooter with wheel off the ground, sometimes it wont...

Well then I dont understand why dealers arent stocking the 5304 motors. If they only have to order 50 Im sure there wouldnt be a problem selling them.

Hey everyone I think that we should all send e-mails to Crystalyte asking them to bring back the 5300 series of motors! I think they are so much better for people that like to run high watts through their motors and they should never have stopped production! Maybe they could even offer the...

I recently purchased a Gio 800W scooter because I want to build a sleeper scooter. I am going to install a Lyen 12fet programmable controller and most likely re-configure my 72V LiFePo4 pack so it will fit in the compartments. I want to run this thing at around 65A continuous or maybe more...

I have started on a new project and I have a question regarding the BMS. My battery is going to be split into 2 parts and it is going to go in 2 separate locations. I will need to extend half of my balance leads to reach the front pack. Is it important that my leads be all the same length...

When I put it to 121% the freewheel speed goes over 100km/h so it does something. I must need to keep playing with the settings on the controller. I wonder if I might have gone too high on the settings?? Tomorrow I will start out at 40A battery and 100A phase and go up slowly from there...

Your right, it cant be the wiring because it did run way better before programming. I really cant understand why I cant get that power back!
