Check with an Ohmeter, the wiring for the motor, including the Hall effect sensors, PAS (assuming you have one), Battery voltage after a charge, Output voltage of charger. Move the wiring around to see if it has a break/bad contact. Do not forget to look at all plugs for corrosion and looseness...

The pedals have a threaded rod (with bearings) in the middle usually, that screws into the end of the crank. One side is a LH thread the other a normal thread. Are you referring to that threaded part being the bolt? I may be wrong, but my memory says that the lefthand side should be a normal...

I like your "Bosh" instead of "Bosch", as the version without the "c", was the word used after WW2 to describe total rubbish, especially from servicemen who had served in Germany in some capacity! I haven't heard it being used for a great many years now! But it is still recognised by online...

Do you have a meter and know how to use it? If yes, tell us the voltage on the fully charged battery please. This is not a 100% check, but it's a start and might lead us further on to the problem, and you have got to start somewhere! regards Andy

I have two Chinese made (supplied with my Bike), large sort of chain type with 5 or 6 links, each about 6" long (from memory, if you want exact details, I will go in the garage for you and take a picture!), and covered with a plastic film so that it does not scratch. They do not seem to be...

Many thanks for your post, demonstrating clearly that without a meter, guessing might have caused serious damage to your e-bike. Sadly its nothing new from Chinese products. For instance, I bought two identical controllers for a friend of mine (he is not an online person!), from the same ebay...

Thanks for the offer, but my mechanical disk brakes exceed all my wishes in terms of easy to adjust, easy pad replacement, easy to dose and how they stop the bike REALLY quickly! As one coming from an old Scottish family, we tend not to replacing something working well for little or no...

Do the brakes squeak all the time, or just with braking? Front and rear the same? Are you able to check and see if the rotors/disks are warped. The slightest sideways movement can be bad. Are the disks badly adjusted and the are touching while riding? The idea from someone to change the pads...

Green LED staying on all the time, is ALSO an indicator that the battery is not charging, as it has "slipped" below the voltage level (for any one of many reasons) at which the charger is allowed to charge! The reason I commented as I did previously, was because your original question did not...

One lock is simply too few! (poor grammar is intentional! o_O ) I feel that you need at least two (the more the merrier!), to block both wheels and attach to a strongpoint in the ground. Furthermore, you need a vibration alarm, to make sure any thief has to go home and change his shorts! As no...

Very well put. And many here have experinced that Chinese companies do not always follow conventional colour coing either! A multimeter is as you mentioned, the only safe way to check 100%. I myself was completely unclear (implying not clear enough for a fully SAFE answer!), as to whether he...

Did you inform yourself fully about the way your bike works and how it is actually following the laws of both Europe and the GB? Do remember that breaking the law may have severe consequences for you at some point. Police in some countries will after any sort of accident involving an e-bike...

I personally think that it is impractical, as you generally need 220 - 240 VAC in your house, though a few e-bike front lights may be useful in a power cut, to light up dark corners..... There are DC to AC converters for making the mains AC from batteries, but they generally need either 12 or...

How fast was that? You need a new name, "Sound Barrier" would do it!! regards Andy

Stay legal! regards Andy

Could be a wiring fault, count how many wires go to the motor and check all connections fully. It may be a Hall effect problem, assuming you have more than 3 wires going to the motor....The thin wires are for the hall effect sensors. Make sure all connectors have no corrosion and are fully...

I completely agree that they need regular adjustments, but not that often! I get through 4 sets of pads a year aproximately, (2 front, 1-2 back, as the back ones wear slower than the front!) and I adjust them when replacing them, and probably twice more for the front and once for the rear, as I...

If he complains about a scratch, even the police will know he was too close!!! regards Andy

I cannot say for 100% certain, but it does appear to be "flexible" as I mentioned. Even if it is not, a hair dryer on hot in the middle of the arm, then when its soft, twist it to suit. Hoöd it with pegs till it is hard again. If it is hard set plastic (heat will not soften it, but there are...

If you make your own, make sure that there is a screw at the farthest point from the bike, that will make a little "reminder" in the paint for any car coming too close! Also, mount using a spring, so that you do not get any twisting from close contact. Both of these are sadly missing on my...
