Your thinking is not correct. There is no limit on continuous power. It's the rated power that's limited by the regulation, and there's no regulation nor test for how the rated power should be determined, except to determine that the motor hasn't been over-rated.

You never mentioned another controller before. Tell us about it. There is nothing simpler than brake switches. One side is ground and the other side is floating at 5v. When the switch is on, the 5v gets taken down to 0v. The switch is either on or off. You can test that with any meter. The...

What you're saying isn't quite right. The red and black wires power the panel with battery voltage. The on/off switch operates both the panel and the controller. When switched on, the red wire is latched to the blue one to provide the battery voltage that powers the controller. The controller...

Lets make it simple by actual case law. I have only ever been able to find one case where someone was prosecuted for riding an illegal bike that involved a woman, who rode a sit-on electric scooter, the type that you can actually scoot, not like a motor scooter. From the court transcripts, the...

7 years ago, they were probably illegal if they were 250w because the maximum allowed at the time was 200w, though even the police were using 250w bikes then. Under today's legislation, they would have been legal. To be 100% compliant, you need a plate on the bike with the max speed...

The battery, when fully charged should have around 28v if you have the 2 x 12v SLA version. You haven't said which version you have. Whenswitched on and powered, the same voltage should be on the red and black wires going in too the controller. The white box is a device that multiplexes the...

You'd need two of them - one for each battery. It's basically a powered diode with a very low resistance, so no significant power loss or voltage drop. You need a ground to power it. I haven't studied one of those, but I'd guess that the other components are to cut down and regulate the supply...

Then it should work when you operate the brake switch unless the black wire isn't connected to ground.

You can see in the photos that he has no spacers..

When you bridged it, did it cut the motor?

The Pro Rider E Wayfarer is a standard Chinese bike that uses standard Chinese parts. Can you explain what's wrong with your bike and exactly what you think you need and why?

We get people making statements like that from time to time. Until now, nobody has ever been able to provide a record of a single case. Here's your chance to change that! Even that guy who killed the woman on his illegal bike was not convicted.

Lot's of info about it here. It might be worth sending an email to Bafang European HQ https://endless-sphere.com/forums/viewtopic.php?t=94553

Red and blue. I always bridge the Tx and Rx wires as well, which are normally green and yellow or white.

The signal wire is held at 5v by a pull-up resistor. When you operate the brake switch, it's connected directly to ground, so cannot show anything other than 0v. The signal wire is monitored directly by the cpu to see if it's a high or low signal. There must be something wrong with your ground...

Wouldn't it be better to wait until you find out what he has before spamming him with confusing adverts.

The 250w is not a restriction. Most "250w" electric bikes draw something like 500w to 900w from the battery, with an efficiency of around 70%, so 350w to 630w output power, when giving maximum power. There is no regulation on the power drawn, nor the output power. Instead, it's on the rating of...

To get the right advice, you need to show photos of what you have - Whole bike; front wheel and forks; complete drive-train; bottom bracket area from left side 45 deg up, and from underneath.

Cut the middle out of the magnet disc so it clears the bearing holder, then glue it to the chainwheel or drill some small holes in it to tie it to the chainwheel.

If it had sensors before, the replacements have to go in the same position. If you didn't have them before, the positioning is critical. They set the timing of each phase pulse.
