That's what I got. Chrystalyte was top of the line years ago. There may be better choices today, but I still like them. I am running 52 volts and 40 amps through a 5305 motor. I love the quiet - non geared. Only one moving part. Sensorless controller, so no hall wires to worry about. I...

I wasn't sure how to respond, but I'll give it a try. I like fixing things. I like to know how things go together. I maintain my bike myself and have replaced parts a few times. I have seen and heard of stuff that is sold on Amazing on and E---bay: 20 amp hour batteries that last 6 miles...

Hey, I haven't been on here forever. Bought a used 1999 EVG 24 volt bike in 2006. See above posts. In 2021 I bought a 52 volt/12 amp (Samsung40T) battery from Bicycle Motor Works that fit the dimensions of the EVG battery box once you grind down the center divider. Of course, they came out...

May, 2024 update - 630 miles After three unreturned emails and a phone call, the tech guy said the wattage-all-over-the-place is normal. So basically useless. Wish they had a voltage readout instead of wattage and the 5-bar gauge. The motor shutting off has gotten worse. Now it does it...

Preferably the 4840 version - 48 volts and 40 amp max that were used by Electricrider and Electroride and others. The ones with the flat connectors. I know these haven't been produced for a while. If anyone has an old working one laying around their garage, I would be happy to take it off...

Greetings, I bought an Addmotor m-340 grandtan with the front motor for the wife after health issues. She rode it a total of two times for about 1 mile each. After that she says she wants to ride it, but never does. I have had it for two years and have put 500 miles on it, mostly grocery...

The stock controller is only getting power from the original battery pack. 25-26 volts. It is only used to power the headlight/tail light/brake light/horn. I checked with a volt meter. I use a new 48 volt Crystalyte controller in the rear bag that gets power from all four batteries (with a...

I know this is an old thread. Leave the old controller in place. Disconnect the two power wires from it to the motor. Leave all the other wires in place. Use a different controller/throttle for the motor. That leaves the headlight/tail light/brake/horn functions still working. This worked...

Sorry for the delay, life gets in the way of fun. It's really not that difficult if you are can work a soldering gun. I am assuming you have a 24 volt model as I do. If you have the 36 volt model, I would just upgrade to a more powerful 36 volt motor, perhaps adding an additional 36 volt...

I purchased a 24 volt EVG ebike nine years ago. Top speed 13 mph. If you pedaled above 14, the motor would shut off. The motor was nice for hills. Bike weighed 86 pounds per my scale. Frame is heavy but sturdy. Anyway, after 7000 miles, the brushes were shot and I could not find...
