    New Member - advice welcome

    Hope the auction price was a steal.. Lets put the refit job into perspective, conversion of a 'virgin' donor bike is an afternoon job within reach of anyone capable of changing a tyre. And with the motor wheel already installed in your bike thats 50% + done before you start. The rest of the...

    Higher watts advantages?

    Cheers @saneagle, i will probably need a few read throughs before it starts to gel, ive lurked on the peripheries of rc and model engineering communities a little not delving deeper than admiration for the most part tho. so other the odd servo/stepper motor ebiking is my first real exposure to...

    Higher watts advantages?

    Im still confused about hub motor max rpm and the impact of running a 36v motor with a 48v battery/controller? Is the motor max rpm a constant regardless of the input voltage or does it also increase inline with the voltage supplied? This seems like a good place to ask ;) Cheers.. btw links...

    Avelo lorraine

    key aspects of your controller/display combo is the 14a peak power rating and the led/dumb display unable to give a dynamic response. which indicate configuration changes are difficult to make without a dynamic display (LCD etc) and any unrestricted top speed would be limited by the 14a limit...

    Electric tricycle iwant to buy

    Hi Alan, welcome along.. Trikes can be anything from a fixed frame 3 wheeler thats a sod to corner beyond 6mph to a high spec recumbent with enough engineering to provide for cornering at speeds more inline with e-bikes Or are you interested in an electric tuktuk type vehicle for cargo...

    There are hundreds if not thousands of ebikes out there and google isn't very forthcoming with details on your bike.. so pictures of the display battery and controller would help identify the systems used.

    Ebike battery renewal

    With a known good battery and a kt display already purchased spending a further circa £50 on a suitable kt controller and cadence based pas sensor (£5-6) is probably your quickest route to success, its just blind luck your current controller shares the same ground, power and speed signal wires...

    Ebike battery renewal

    Yeah, confirm your controller is also KT otherwise you could be chasing your tail indefinitely, KT is short for Ketung iirc, many controllers are silver boxes, but KT controllers also come in a down the tube option or in the battery sled (hailong batteries) types too.. If difficult to unbury...

    Motor diagnostics..

    Cheers @harrys, thats why im asking any switches i have rated for DC current are both quite beefy (large) and not waterproof at all.. @saneagle.. -- say what?? Perhaps its worth opening up the shrinkwrap for a look at the bms pcb.. Even if i find well labelled solder pads however i think i...

    Motor diagnostics..

    DOMINOS and not the pizza one thing lading onto another.. I got the whole bike back to test the wheel connected to power, and upside down the battery is not making a good connection.. and as this battery has no on/off switch, trying to juggle the battery against gravity into place just...

    Help! New and in need of help.

    Hang around in here and you will learn Saneagle is ALLWAYS right when it comes to ebikes.. But since google gave me so many 90 sec vids on how to de-reg (lift the speed limit) of your bike.... -many bikes feature code lock outs, if not used however?? A teen prank without thought of...

    Help! New and in need of help.

    I dont know your bike or its operation, but no mention above of any configuration settings or checking there of. even with my eu/uk 'hobbled' controller f/w i have access to a few controller settings, Could a display button/controller fumble or ?? have resulted in something getting set in...

    KT controller compatibility with Mahle

    KT brand controllers are popular because you can select any LCD display from the range that meets your aesthetic KT-LCD3 is t most popular and probably the cheapest. google and check out the manual pdf files for the displays you are considering ;) (20+ pages) For a 250w motor, most bikes...

    Swollen battery

    I doubt it will spontaneously combust, the energy in most of the cells probably dissipated in the expansion But if you start pumping fresh amps into it it could behave unexpectedly.. As for the number of connections, its probably a future-proofing of the battery format if for example 1...

    Swollen battery

    Just in case Visible swelling through the hard plastic exterior case is a VERY RED FLAG ;) And since your asking here you have the good sense to check ;) so just to be 100% clear.. IMHO DO NOT ATTEMPT TO CHARGE THE BATTERY IT COULD END VERY BAD
