Have a look at the bikes with 24" wheels, which are specially for short people. There's this Wisper. https://www.e-bikesdirect.co.uk/electric-bikes/step-through-frames/wisper-705se-stealth-24-wheel-electric-bike-red and this Juicy...

That motor can easily handle 36v 25Ah.

Only a nut case would fit a Cyclotricity 500w kit to a carbon fibre frame! The motor is massive. What's the point of spoiling a light weight bike with an over weight motor. There's nothing wrong with the Cyclotricity kit, but if you want one, stick it in one of those cheap catalogue bikes that...

In simple terms, there isn't an easy fix. The motor will need a substantial repair that most ebike shops wouldn't want to get involved with. They just replace the motor wheel complete. Your bike will need to go back to the supplier for repair, or they might just send a motor wheel for you to...

You can check the battery yourself with a proper battery load tester or by going out on a 50 mile ride. The cheapest load testers from China are about £100. Bosch batteries can be checked by some dealers who have the special tester, which gives an official report on its condition. Some...

I only got the story second hand. The guy that told me that the company wrote to some government department and was given a reply that it was OK to use throttles on their bikes. They may have already had type approval to L1eA. If not, maybe they do now. I hope you don't think I was laughing at...

This is the problem. People read stuff on the internet and then jump to conclusions. I don't know how many bikes I've had to fix with symptoms like yours, but I can say that only one had a faulty hall sensor, and that was a big direct drive motor like the one in that video, where hall sensor...

Question still not answered. I'll try again. Is a 25 km/h 250w bike with pedals and a throttle and type approval an EAPC? The bikes referred to in the OP had type approval as far as I was told. Sorry Flecc, you ninja'd my post. Thanks for clarification.

The words in the last two posts still don't make it clear. Is a 250w LPM with throttle and Type approval an EAPC? In other words, are you confirming what I wrote in the OP? If you're still reading, Mr Wisper, is that a 250W 48v 100 NM EAPC? I was chuckling at the thought!

Where did you get that from? I have seen some ebike chargers that latch off, but most are CC-CV and hold maximum charging voltage as long as they're connected. That's important for balancing.

This is the one. https://www.ebay.co.uk/itm/24-29-4V-2A-Lead-Acid-Battery-Smart-Charger-3-Step-for-Electric-bicycle/233032514989?hash=item3641d1fdad:g:eJAAAOSw1ExcBVh3&redirect=mobile From UK if you need one in a hurry...

Hall sensors don't normally blow these days. The problem is more likely a simple connection issue. First, make sure that the connector near the motor is pusshed all the way in, then, if you have bullet connectors at the controller, make sure that they're tight. Many of the bikes I have to fix...

You're wasting your time playing with those parameters until you have the basic protocols set, which is C11. You know it's correct when you can see the watts changing on the right of the display. Once you have that you can set the throttle and PAS parameters and anything else if you need to...

You should be able to apply some logic. If the cut offs are purely random and you can switch back on and ride some distance before it happens again, it's most likely a connection fault. On the other hand, if it doesn’t do it when the battery is fully charged, but starts to happen when the...

If you must have connectors, then XT60 or Deans. Andersons can bend until they don't make proper contact, and they're harder to solder and assemble.

Cut them off and solder the wires together. That's a cheaper, easier and more reliable solution.

The problem is that you rode the bike through 4 months of dirty wet salty winter roads. Had you used it in the summer, it would still be OK. You can't do any damage to the pedal sensor no matter how hard you pedal because it's mechanically isolated from the drive train. It functions by observing...

The frame is very low at the back, so you won't have any problem getting your feet down.

The free Google navigation is hard to beat. When ser to cycling, it will find and use aĺthe normal cycle paths and routes. When you turn off the road onto a cycle path, it even gives you a photo of what you're loking for. It'll automatically re-route you if you deviate from the planned route...

The on/off switch, battery indicator, temperaure all work directly in the LCD because the LCD has its own CPU powered by a pair of wires that come directly from the battery. When you try any function to change something in the controller, like, power level, max current, cut-off voltage, max...
