Re: New "Lingbei MM28.250 torque sensor mid drive"

I don’t think i will need more than 350 watts so i might cope without temperature sensor :D The noisy thing worries me a bit though. It is noisier than an hub motor but as silent as Lingbei. The ones I have here are definitely way way louder than the lingbei, even with regrease. The lingbei is real...

Re: New "Lingbei MM28.250 torque sensor mid drive"

@slowco that's an excellent proposition. The tdsz2 is very nice for range. It's pretty noisy and lack torque but it does make wonders for battery consumption :)

Re: New "Lingbei MM28.250 torque sensor mid drive"

The lingbei aren't long range mids. They tend to have a high consumption at lower assist level. I use them strickly on cargo now. They are absolutely perfect for this. For reference, with a 800wh battery the range on a emtb used on streets is about 70-80km. (At 25-30kmh) With a 500wh, and use VERY c...

For the same length no. More or less for displacement hull the rule is the longer, the lighter prevail. ...

Re: KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW

I have an S06S flashed with this firmware, and when I turn on the kit, the motor starts going at a moderate speed and doesn't stop until it's turned off again. I finished my experiments with the firmware because of the behavior of the thumb throttle that does not suit me, as I wrote above, and retu...

Re: New "Lingbei MM28.250 torque sensor mid drive"

I use the lingbei a lot. They are "flashable" not "programmable". Which means you can get different factory firmware to be flashed. From my experience, they have way too much consumption in the first assist levels. That sucks real hard for clients having small (500wh) batteries. ...
