    Crystalyte 4 wire throttle to 3 wire

    In general, BMC to Crystalyte wire mapping is as follows: Phase, BMC --> Xlyte blue --> yellow green --> blue yellow --> green Hall, BMC --> Xlyte green --> yellow yellow --> blue blue --> green red --> tan/red black --> black I don't have any of the V3s here, though, just the V2s, so I...

    Nine Continent hub motor and vertical rear dropouts

    It sounds like the issue is not dropout spacing at all, so bending the frame is not a solution to the problem. If the motor axle hangs 4-5mm below the dropouts when fully seated, it is as Icewrench has pointed out, the dropouts are not deep enough. You can usually get away with a few...

    Need Help Identifying Battery and Finding Charger

    I agree; install a BMS. We used to sell those same batteries (though we got them through BMC), and the balancing charger works great -- when it works. But the 15-pin connection is annoying and often difficult to line up properly, so it's easy to short a cell and/or vaporize the end of a pin...
