ELECTRIC BIKE CONTROLLER 250W 24V 10A- SENSORLESS & HALL SENSOR COMPATIBLE ELECTRIC BIKE CONTROLLER 250W 24V 10A- SENSORLESS & HALL SENSOR COMPATIBLE | eBay This is the replacement I am trying to fit

Very hard to get a pic of all wires. I have not used the three speed controller, speed limiter and connected the ignition ones together.

There seemed to be some oxidisation inside the unit.... And white crusty powdery stuff on parts of the inside of casing...... Possibly wet?

It's a generic 24v one from eBay as was only small one I could find.

I'm so sorry..... I'm struggling between looking after the kids, cooking and bike in bits in middle of floor! So opening the throttle a little bit starts a motor noise but no turn in wheel..... What's the next step?

Quick update..... When I turn the throttle..... The motor now makes a noise..... But the wheel does not turn...... I did some fiddling and this is progress..... What could be making the throttle work, motor makes noise but no turning? I am sensing this is now a voltage/power problem? Only...

And these wires..... No power out of any!

This is what I mean about the brake cut off things....

And in self interest of being rather proud of my non successful effort..... This is what I have done!

Ok...... I'm back! I followed the links from other posts you have commented on and did testing of all the in outs and determined power was most certainly going in but not coming out. Control box was most certainly dead..... In the interest of being an unreasonable woman I opened the box and...

Thanks..... Will get voltmeter and get down to some serious testing with guidance!

Electric Bike Sine Wave Controller with Hall Sensor/LCD Display/Throttle/Light-in Other Sports & Entertainment Products from Sports & Entertainment on Aliexpress.com Oops!

Found this..... Looks most like mine which will mean wont have to change all the connectors and mine has integrated electrics for lights which is included in this. Long lead time or delivery. I welcome advice or uk supplier of like box!

I'm seeing controllers on eBay but some are 250watts and some 350 or 500..... And looks like I would need to change the connections...... I know mine is 24v but no idea of wattage!

Ok.... Dad has given it a once over..... Final verdict..... Power going in and out of battery..... Into controller but not coming out. Are the controllers expensive to replace?

No power out of bottom of battery, fuses fine and then bulb in connection tester thingy blew before we could check ignition so my dads carted it off to have it checked out!

LEDs on battery throttle don't light up. No lights anywhere at all so I was thinking problem between battery and whole bike! Guy next door will want to lend me more than a voltmeter if I knock on his door now so will have to wait till morning. No way the whole bike could be blown right? There's...

Checked that. Saw you had that on another thread. Before you ask.... Don't have a voltmeter. Have to get one. I find it odd that the headlamps aren't working either. That's a separate wire from the chunky one in the shrink wrap rubber stuff. Just saw your modification thread and was wondering if...

I'm new to electric bikes or any bikes at all actually! Got myself one because the school run is too short to warrant a bus fare but too far for a little one to walk or be carried and up a long steep hill. The trailer works great at the back but a bit of a pain if I want to go somewhere after...
