    How do I select a suitable motor?

    Did I got that right? My max RPM is 5000 RPMs adding 10-15% low voltage at my project is 60V So is this correct:? 5000*1,1*60V = 330000 = 330Kv ?

    Sur-Ron Battery upgrade

    On the website it says the BAC 8000 supports 72V nominal. My battery, fully charged goes up to 84,0V. Is this voltage still supported? If yes, I would consider switching my project over to a BAC 8000, as my current controller (Mobipus 72600) is quite hard to set up software wise.. :( Would...

    Just saw my post from around a year ago and I have no clue, what in the world I've just done back then. The "trick" from then doesn't really work. Meanwhile my pc doesnt recognize the controller via USB nor WIFI dongle. Any help?

    Vector bike and frame owners.

    I recommend to buy the Vector Typhoon with battery. I could have saved myself a lot of trouble with building my own battery by buying the prebuild batterypack. Looks like the CAB Eagle is just the cheap chinese clone of the frame where the whole thing gets rusty after some time etc. I have my...

    Mobipus Controller Write Parameter to Controller issue

    Just updated to the latest version of Mobipus and now I have full access and the "change mode" button got removed, compared to the dropbox link from ballaratebike's website.

    afaik you can use the QS 205 V3 hub motor easily. The dropout width is only for the different rim / wheel sizes. In case you want to have a fat bike tire or not for example.

    Help me develop the perfect throttle

    yeah sorry haha, haven't spend a lot of time on ES anymore as I do a lot of climate-change activism on EU level lately. What exactly? The time for building a prototype, the late reply? Don't understand
