    Where do I get special spokes for my hub motor?

    A week ago or so, some spokes broke on my hub motor. I took my hub motor to a bike shop and I asked them if they work on ebikes. They said yes no problem, they'll take the wheel and have the bike mechanic look at it and they will call me later. They call me later and tell me they cannot find...

    Will my hack-job battery splice work?

    I attempted to add another battery to my bike in parallel and the way I did it was to cut the wires leading from the battery to the controller and then I rejoined them with quick splice crimping connectors, except on one side of the connector an additional set of wires are connected that then...

    I have been checking ebay listings and almost all of them show the wheel missing the rear sprocket. Am I suppose to reuse the one from the donor bike? Is that easy to do?

    Better passenger solution A.K.A. save my marriage

    My wife doesn't like biking. I bought her an electric bike, so she and I can ride around. She kind of hates it. And I get totally frustrated by her slowness and refusal to try to keep up with my speed. She likes to go about 8 miles per hour and it drives me insane. I used to let her ride behind...

    "upgraded" motor controller, now bike is slower?

    To start, I don't THAT much about these particular controllers, especially the stock one. I replaced the stock controller on my bike with a Sunwin controller from ebay. The bike was advertised to have a 750 watt motor. The Sunwin controller is 800w. It's basically this one...

    Trying to identify and get wire diagram for this controller

    Can I use lithium charger as fast charger for SLA batteries?

    I have a SLA charger that's rated at 59v and 3 amps. I also have a lifepo4 charger that is rated at 60v and 6 amps. It's my understanding that a SLA charger will continue to trickle charge after a full charge is accomplished but a lithium charger just shuts off. This is probably ok. I was...
