    Is this a viable bike for conversion? (Updated)

    " That last is usually a sign of a hall sensor problem. Either a connection issue, a wiring problem, or an actual sensor failure, causing the controller to be unable to determine the rotor position, and so sending the wrong phase order signals and causing it to spin backwards until it reads the...

    Is this a viable bike for conversion? (Updated)

    ^This. It´s working properly, just with more output. barely gets warm at all Got it... I´ll reasearch about it, hope its fixable. Apart from the problem it self, theoreticly, am I loosing "Power On" time because of that sensor? Could this be caused by overheating? I have a Temp sensor on the...

    So this one was not yours? ;) https://endless-sphere.com/forums/viewtopic.php?f=49&t=110161 The one I showed now is the first one I built, and owned ;) I have also the sondors bike and a foldable one. We live in a hilly area unfortunatly... All that will be taken into consideration, for sure...

    Is this a viable bike for conversion? (Updated)

    Hi everyone :) I´m planning on building my second e-bike. Hope this one turns out successful as the first one :mrgreen: So this is my first ebike. I intend to do a similar build with a few differences. It was built 3 years ago. 58,8V 14,5Ah 14S 5P Panasonic PF cells, with 130 cycles to...

    Sondors Ebike problem

    If the switch is just one wire that goes out and back in the controller, how do I measure if its getting power? btw, when the switch is turned off, the two wires measure 41V, when they are closed they read 0V. seems strange to me but might be normal. Hmm ok it would be a waste of time, I see...

    Sondors Ebike problem

    Just checked the throttle switch, lights up the LEDs everytime. Also shorted the corresponding wires and LEDs light up. The main battery switch works, otherwise the other one would not work. It has to be either the variable resistor in the throttle, or the coontroller is fried or has a lose...

    Sondors Ebike problem

    Ok, but if I disconnect the throttle connector I can´t turn on the controller unless I short the wires that go to the throttle switch. I´ll try that. I´ll try that and report. This bike has a battery switch on one side of the box and a controller switch on the throttle it self.

    Sondors Ebike problem

    yeah its not reading anything :? Before I try to take apart the controller, should I try using a different throttle? Could the problem be in the throttle it self?

    Sondors Ebike problem

    Sorry for late reply, I've had so much work plus the weather was awful to work outside:( Ive tested the throttle using needles as Voltron suggested (thanks for the tip), and Black/White/Red + Yellow Blue and Green gives me the battery voltage of 41V, but Black + White/Red keep at 0V when...

    Sondors Ebike problem

    I´ve done it for my 1000W it is no big deal. Yes it has a water proof connection for all connections. I picked inside the controller and I couldn´t see how to even get the board out. Ok cool, I´ll start with the motor then. So I check every color with the black wire? is black common ground for...

    Sondors Ebike problem

    UPDATE: I did some tests with the bike and both break switches are working fine, unfortunately. Then I hooked the phase wires to the multimeter, spun the wheel backwards and I got a reading. Does this mean the motor but is possible the signal wires aren´t? Now to test the controller... should...

    Never thought about the break switch I hope the problem is that simple! Thank you all for the input, I try a few things and report back soon :)

    Sondors Ebike problem

    I meant it was not the batt - controller connection. That´s where I have doubts... The controller is getting power but I don´t know how to test the output going to the motor. Is it safe to throttle if I have no load? Also, in the case the motor was burned out... could I know it by measuring...

    Sondors Ebike problem

    Not much to say really, I rode it last month with no problems, climbed a few hills as usual and used half the battery. Weather has been rainy and grey so I didn´t use it for a month and stored it as it was. Recently I gave it a charge and it wouldn´t spin, just like that :? I don´t believe I...

    Sondors Ebike problem

    Hi! Recently I was going out for a ride with my Sondors fat ebike but it wouldn´t work :cry: The battery is fully charged and turns on all the lights (its a tube battery) but when I throttle nothing happens. The thumb throttle lights up the battery voltage LEDs so... it should be good? Is...
