China EBikes (cyclone)

I bought two bikes, not running, off craig's list. The one had the throttle and brakes assembly was gone. I lucked out of this bought both, replaced and it worked. the second bike had a fried controller. This unit runs on 24 volt nicads, placed under the seat. I purchased a crystalyte controller and can not figure out how to hook up, the bike has 5 wires coming out of the motor (rear), the controller has only one three wire connector, Oh what to do ??

The Rezistor - Main Power Check

I figured it would be a good idea to check the function of all the major components, so yesterday I hooked up the motor, controller, contactor, throttle, and one of the batteries. I have not yet purchased the main power cables, so I had to make do with whatever spare lengths of monster cable and bits of 18 ga wire salvaged from previous LED and cold cathode lighting projects.

Kelly controller is hooked up for the elite project

This afternoon David and I were able to hook up the Kelly controller to the Honda elite.
However I kept scratching my head on this one :?
because the Kelly controller looked so much like an air filter to me???
Maybe because I am more familiar with general maintenance on vehicles?? I dunno, but I just kept thinking
of how the top part of the controller looked a lot like the fabric of a simple air filter.


2 speed controllers.... do they work?

Hey All, This is my first to post.

I’m seeing that people are selling all different types of ebike controllers. They differ in amps, volts and offer 2 speeds and even reverse. What does all this mean?

I have a new Crystalyte 48v 500w front hub motor on a 26” wheeled 3 speed cruiser style bike. I’m guessing I go about 23-5mph on the flats.
