have you checked for shorting in the main waterproof cable and the LCD? if it's just one of them, then you wouldn't have to remove the motor.

If you only have £1000 budget, then the Woosh Big Bear is about the best bang for buck. It has BPM motor and 15AH battery. http://wooshbikes.co.uk/?bigbear

I thought that the BBS02 750W 48V uses 13S battery. Two 6S in series may trip LVC.

personally, I don't like direct drive motors for hills because of poor torque and high consumption, so I would rule the RXS out. The Ebco is well finished for a Chinese bike but again, hillclimbing performance is not great. Kalkhoff bikes are solid value but seem expensive against other German...

test the voltage with a multitester when you get error 7. At least you can discount some of the possibilities.

I rarely fill in those questionaires - I always check the URL first. There is always a risk when the page is not hosted on a legitimated (.ac.uk) website but some unknown site, for all you know, the page can contain internet malware. I think this forum should have a database of approved domains...

they are about the same. Don't worry.

your colours are correct but don't connect the wires, the connectors are mismatched. You need to replace the connectors on the BBS01 side with matching crimps (3.9mm Japanese bullet connectors). Crimp the male to the red wire, the female to the black wire. You can solder the connectors but...

I unscrewed one of these levers sometime ago, can't find the damned thing whe you need it. The plunger moves a tiny magnet, about 3mm in diameter, against the body of the sensor. The sensor itself is a tiny Hall, if you rotate it 180 degrees, it changes the active signal from high to low. the...

why did I imagine you have access to a 400W laser cutter... Thank you for the tip.

they work on the same principle. I am thinking of borrowing your idea of making ali brackets to add sensor to my Auriga brakes. How did you cut your sheet? the edges look quite neat.

I thought your bracket has a very nice shape. could you have used the smaller sensor from the brake levers with the same technique? the sensor can be unscrewed easily, cylindrical in shape, about 4mm diameter and 10mm long.

would it be better if the aluminium bracket was bigger and sandwich in the sensor?

cost. small volume production.

I was thinking of getting this one for my little project: https://bmsbattery.com/ebike-battery/731-36v10ah-bottle-09-e-bike-battery-pack-battery.html I have no idea what is included besides the battery and controller, like waterproof cable, display unit etc. If the item is the whole kit then...

do you know where to download the datasheet for the integrated 20A controller with that 36V 8AH battery?

they look very well thought out though: folding, crank drive, good rack, hidden battery, alloy wheels, hub gears and mobile app. They could very well succeed.

about 30mph with a 48V 25A controller. The power consumption goes up very quickly with speed. With a 48V 10AH battery, I reckon 50 miles at 15mph, 15 miles at 30mph. You can mount this kind of kits on more or less any bike, MTB, road bike etc does not matter. The torque is not huge, just...

it's a 2 minute job to bolt the square bottle battery onto the rear rack if you can't rivnut it to the seat tube.
