    Source for small 36 volt battery - not LIPO

    I'm looking for a small 36 volt battery for a bike where I need very little range. Something like a 3 - 5 ah. Haven't found anything from the sources I usually use for longer range batteries. Thoughts?

    Can I run 48volts on 36V250W SWXU Front Drive V-Brake Hub Mo

    I'm considering buying the very small 36volt hub motor for the front wheel of my recumbent. https://bmsbattery.com/ebike-kit/602-36v250w-swxu-front-drive-v-brake-hub-motor-ebike-kit.html I already have a 48volt battery and BBS-02 on another bike and I'd like to use this battery on the...

    The Lightest Mountain E-Bike Ever - Crank drive

    How hard to you think it would be to recreate this drive setup? https://www.electricbike.com/lightest-bike/ It looks fairly simple. I'm looking for a motor setup that would be very lightweight that I could add to my recumbent and use just on the steepest hills for a couple hundred watts of...

    BBS02 gear strength low load shifting

    I've got over 500 miles on my 48v BBS02. I always tap the brakes before I shift to cut the motor out, but I hate the throttle delay afterwards. I normally am only using around 500 watts when I ride. Would I be safe shifting under load at 500 watts? Seems like since the motor can handle over...

    I mounted the BBS02 on my Trek FX with a 73mm bottom bracket. Everything looks lined up, the the right crank sits a good half inch further outboard than the left crank. Also the chainline is horrible. I can't use the top 3 gears of my 8 speed rear cluster. See picture. Is there any way to...

    Bicycle boxes, fasteners, hangers, etc

    I would love to see pictures and here what people are doing to fasten misc small boxes, controllers, switches, etc to the frames of their bikes. I'm builing a BBS02 with a battery on my down tube. I need to fasten on a couple of switches, and a small dc-dc converter. Right now I'm planning to...

    BMS battery doesn't shut off completely

    Anyone know why this battery only shuts down to 27 volts instead of off when the key is turned off? Is that just to prevent a spark when switched back on? http://www.bmsbattery.com/48v/476-48v-10ah-lithium-ion-alloy-shell-ebike-battery-pack.html

    Ideas on mounting battery pack to frame

    I thought when the battery pack arrived it would be obvious how to attach it to the bicycle. There's plenty of room to mount it on the downtube of my extra-large diamond frame. I just need some ideas. I don't want to mount it on a rack on the back because I haul about 20 pounds of gear on...

    Chinese battery pre-flight check

    With all the quality issues associated with Chinese battery packs and BMS units, could some long time user provide a post on some standard tests, checks to perform prior to using the battery, BMS, and charger? Please add pictures that make it helpful. Thanks, Michael
