Read and research all you can on Pedelec and similar forums about Bosch bikes and mid motor bikes generally, before making any decisions further, is my best advice. Some work for years, but far too many don't, and they are made to be very difficult to fix, and parts are NOT sold to private...

There is also a rear light from ebay, that goes under the saddle, with the features you mentioned, plus its a loud alarm with a remote control and USB charging internal battery. When using just the alarm, the battery holds up for over 3 weeks, maybe even longer..... Once you loosen one screw...

Interesting, but I wonder how the drive mechanism will hold up to dirt, dust and mud? It will probably work fine on the streets in towns and cities, where its far cleaner than where I go..... I wonder how easy it will be to remove/replace a tyre.....? At night, to possibly repair a puncture...

https://www.instructables.com/A-Commuters-Electric-Bike/?utm_source=newsletter&utm_medium=email I believe that this possibly comes from the USA, and with a suitable and legal motor for where you live, might allow a good e-bike to be built, so do have a good read if you find the possibility...

May I suggest that you leave the motor alone for now at least, nothing you have mentioned makes me think of motor. My thoughts are battery, battery charger and it's fuse, and possibly controller wiring and possibly a fuse. Motors can easily be damaged by the wrong hands and tools, and even if it...

Have you not considered that you may have a battery/charger problem..? That's where I would look first, with a voltmeter. Andy

If someone is sensitive to epilepsy and flashing lights, I doubt that they will get a driving license! So many things flash from ambulances and police cars and people using them as turning indicators...... I would rather like to see bike riders with lights of any sort, too many ride dark...

Some people adjust their front lights far too high, and with the great modern LED lights, that maybe the cause of the problems with opposing drivers. Which is partially why I have two, one is for distance and the other basically is as though it was dipped. Though the main reason for having two...

As VFR400 said, as long as its a 48v Motor 250 watt, it will work. But the electronics appear to be built for up to 1000 Watts...So about a quarter of the heat will be released in the electronics you have just shown us, theoretically, it will never burn out!! It will be just "idling" along...

Use your batteries alternately, assuming that removal and replacement is easy, on say a 4 week cycle, as Li-ion batteries do not like to "be ignored" for long periods. Having a cheap Multi-meter can save a lot of errors, assuming that you do not already have one..... regards Andy

If you had actually used the motor power (750W), the range would have been far less, as to double your speed, requires 4 times the energy or battery capacity....simple physics. Only someone with the same motor, but driving far slower, could find out for certain what actual power savings might...

If you ride legally, never go over red at the lights, keep to within the legal electric range of speed, not ride anywhere just using the throttle etc etc., you are unlikely to be found out.... Or you could legally get it registered as a Moped (I believe!) pay road tax and insurance, use a...

My post was for possibly fixing the Vernier Calipers.....you mentioned that they were not working correctly, its a not uncommon problem! Andy

Replace the battery in the Caliper. If that doesn't help, remove the battery and short out the contacts on the unit where the battery would normally fit. Press all buttons (all done to fully discharge any caps). Check the new battery voltage is within range for (usually) button cell used. They...

You say the battery is fully charged, but the only way to know this for certain, is with a reasonably accurate DC Voltmeter. Is that how you checked it? Or are you going just by the colour of the charging LED? Which can be most misleading. How old is the battery now? Would also be useful...

It was meant to warn you of some of the dangers associated with e-biking. Replacing wheels with electric ones, on a frame never intended to have such a motor, is not a way I would go myself. It can go well of course. Furthermore, at least some of these owners of such conversions, land up here...

Sadly, it will be considered completely illegal for anyone in either the UK or the EU. Though some do not let that bother them in the slightest apparently. 250 Watt is the legal max allowed in many countries. Whether you will get caught and prosecuted, especially if you observe the maximum...

Maybe he uses an electric motor to "wind up" his clockwork toy? ;):(:mad:o_O:eek: Just a thought! Maybe he never heard of conservation of energy either.... Regards Andy

Part 7. By the way, someone here worked out recently that riding a high priced e-bike can actually cost more per Kilometer to run than a small car, when viewed over a few years, sad but true!!! And most people have both! Have a great day.
