Its a badly made unit as the screws and their holes are missing, so is the heat sink paste, that should be keeping the transistors hard and cool against the heat sink. So you may be lucky and replacing them will bring the controller back to life. But do add the screws, plastic insulating washers...

What some people do is to take any old worn out tyre and cut the tread off and insert it, with a few spots of tyre cement, between the inner tube and the outer tread pattern. This reduces the size of the inner tube needed, and adds some valuable millimeters of rubber to absorb any thorns abd the...

Then wait and see how it works. But if you get problems, then find someone with an O'scope to look at the output wave form of the inverter... Best of luck. Andy

Make loads of pictures just in case you can correct the fault and need to be reminded how it all goes back together... Separate all six wires and try the spin test again. Is this a middle motor or not? IMHO only, is that the motor is finished....sorry! That looks like severe over heating... Andy

Possibly the Hall effect sensors are shorted, though how that would affect the motor I have no idea - I am assuming that you have them, not all motors are so fitted, but you haven't told us whether you do or not! The total number of wires going to the motor will help.... But it certainly bodes...

As others have said, its most likely that the controller is damaged, as I have never seen one with a safety diode built in to prevent damage. Some good ones may have, but guessing only! Furthermore, the motor Hall effect sensors (if installed, the motor will probably have 6 or 7 wires going to...

Never tried it but it should work. The biggest problem with some inverters is that other electronics might take exception to, is possibly the shape of the sine wave output. Many cheaply made inverters have an appalling "square wave" shaped output, nowhere near to it being a sine wave, as the...

I feel that a second battery is the best move, with my bike there are 3 power sizes/weights, (all physically the same dimensions), and one can fit into a pannier....but I do not leave it there if I need to park.....I have a bag that goes over my shoulder for that reason. My second battery is the...

Guessing only, that would imply a front wheel motor, which I personally don't like, or the complication of one of those Bosch units with the cranks, which I also don't like.... regards Andy

Tell us your battery voltage and a photo of the connector at least, but with this info you should be able to buy a charger on ebay...... Why do you need one? What happened to the old one and "when"? Do remember that Li-ion batteries, if they slip below a certain level of voltage, will not charge...

Every bike owner needs a stand, for safety and ease of working. They do not even cost much nowadays.....I do believe I paid 30 UK Pounds for mine about 8 years ago..... They fold up relatively small too! I have the middle one with 4 legs, not shown fully "out" in this photo though!! They are...

AHHH!! There are lube units that you sit on the chain, fill with oil,raise the rear wheel and move the chain in a forwards direction..... https://www.ebay.co.uk/itm/Bicycle-Chain-Cleaner-Bike-Maintenance-Tools-Lubrication-Cleaning-Wheel-Wash/322937428741?hash=item4b30921b05:g:-koAAOSwDEtaMNae...

Pictures or a video might help further. Maybe the deraluere (Spelling?) spring is not set up strong enough? Or it needs oiling... regards Andy

This might give you a start:- https://www.bosch-ebike.com/nz/service/downloads/ or simply call them! regards Andy

There are great and sensitive alarms that cost less than 15 UK Pounds from ebay, fit under the saddle and are also a red rear light, and have a small remote control. Add one of these to the bike as well as any other security! regards Andy...

The problem is as I see, not obeying the law will possibly force the government to be more Draconian I feel, heavy fines for those caught, then we will all be made to have number plates, road taxes, insurances and the like..... I feel that if we stay within the law, those sort of problems may...

Assuming its a Li-ion battery, he did not keep it charged all the time. I could make some guesses as to what he did if you wish to hear them.... What is being seen is when a Li-ion battery goes below 30% charge (which is considered to be the discharged point for normal usage), there is circuitry...

Good for you!! I am still unable to help further though, sorry, as I simply do not know enough to be of any help. I am sure that others here know far better exactly what is required! regards Andy

Super photo!! I have never seen one before, really interesting for many here I would imagine!! My personal take, as you have little in the way of protective clothing on, no helmet for example, is to say leave it as it is..... Furthermore, what does the law say with regard to such wheelchairs...

I am a bit out of my depth now, but if you have a wheel size adjustment, try programming a smaller size wheel, that should help to increase the max speed available. Is it still on a wheelchair, or is it now on a bike? regards Andy
