    A2B Ultra Motor Identification

    ok i think i am close to answering my own question. Upon further review: 1. i tested hall wires near controller using the diode test method in other threads. This prooved 2 hall wires good and one bad. Upon inspectiona hall wire had gotten loose. Incidentally bike road the same with or...

    A2B Ultra Motor Identification

    yes i am doing in this order 1. connect self leanring wires 2. connect power 3. wheel starts spinning in forward direction (without any throttle as soon as power is connected) 4. If i apply throttle, wheel reverses direction 5. apply some throttle again, wheel reverses back to proper direction...

    trying to configure my first ebike. when i use leanring mode, wheel spins forward. However, when i apply the throttle, the wheel reverses. Everything i read says it should not do this, but rather increase and speed and not reverse unless i disconnect and reconnect the learning wire. Anyone...

    I am new to ebikes. For my first build I'm close, but in configuring my controller I have a "learning mode" for a cheap chinese controller. It worked, i connected learning wire, powered on, wheel spins forward. Oddly with throttle wheel reverses direction. in proper spinning direction i...

    Hi I am new to ebikes and attempting my first build as a hobby I have a cheap controlller, 1000w from china/amazon I am attempting to hookup to motor (3 wire), all sensors (5wire), throttle (3 wire) and power (2 wire). Should this give me power? With the power connected to the controller i...

    amberwolf. Since your bike shares the same phase wire coloring, do you recall the _dc5v and grnd wire coloring. of course, if my halls correspond to red white and black, that leaves me with orange yellow and blue for possible5vdc and grnd.

    A2B Ultra Motor Identification

    A very nice person gave me the wiring diagram for the Alva+ and please do compare to my photo of the cable i cut off of the rear wheel. So Everything makes sense except, I have a white wire on the photo of the connector, and the wiring diagram shows a "green" which is missing. Can i assume the...

    A2B Ultra Motor Identification

    So I think I've confused the issue a little bit. I do have a Velocitti, but in the midst of things, I messed something up and ripped out all of the wiing. With all the wiring out, I am going to replace the rear wheel with the rear wheel of the Alva+ a2b which has a 9 pin connector, which I cut...

    A2B Ultra Motor Identification

    Thanks guys, so your best guess looking at this wiring is that it is indeed a 3 phase non internally controlled? If so any idea on how to determine the other 6 wires 3 halls, 5v?, grnd and speed?w Any recommendations on an external controller? Thinking dual mode controller and start off with...

    A2B Ultra Motor Identification

    Hello, first post. I recently bought a brand new a2b velociti. The bike seems to be similar to a2b Metro and a2b hybrid overseas. The bike was missing the battery. I've made a very nice battery pack 36v using greenworks 40v batteries and diodes to protect each. However, I've a few questions...
