Hello, I am tired of the frequent electronic breakdowns on my MBK electric bicycle, powered by a Yamaha mid-drive motor (PM series). So, I think about adapting an external controller. I have read about some swaps on Bosch or Panasonic motors, but could not find the topics. I know that I will...

Hello, I have a MBK bicycle with a Yamaha crank motor. Due to the EU regulations, its power is limited to 250W. I am used to ride a bike with an unrestricted hub motor, so the MBK seems rather weak compared to it. I tried to series a 12V battery to get more voltage (originally 36V), but the...

Surprisingly, my BMSBattery controllers work with my Puma-Ezee geared motor, despite some stumble at acceleration.

You seem to be right Russell, the curves fall suddenly above 20 mph. I knew that, but with other controllers, when the speed reaches its peak, power and speed stay constant, so the ride is always smooth. In the present case, when the power falls, you can't sustain your speed, it falls, then the...

I've got a 350W and a 500W controllers from bmsbattery and here are my observations : - They can work sensorless with my Puma and my GM (I fried some hall sensors) despite some vibrations and noise at startup. - I drained one battery, because neither the bms nor the controller cut off. Need to...

Hello, I fried my wattmeter twice in 2 weeks (in fact 1 Watts'up and 1 Turnigy). I used them on a trike with a GM 16" front wheel and a 48V battery. The first time, my GM rege controller sent more than 70V to the wattmeter (limited to 60V) though I was only riding at 10 mph ! So the wm cut off...

Hi, I have tested the 12 mosfet controller with my Puma motor. It can only reach 15 mph on no load, whereas it does 27 with its standard controller. Do you think that the 12 mosfet controller has a feature that limits the current in order to comply with the european speed limit ? If so, how can...

Nobody ? Today I've tested the motor with no load on 36V. Here are the results : original controller : 46 km/h (27 mph) Goldenmotor "rege" controller : 41 km/h (24 mph) BMSBattery 12 mosfet controller : 25 km/h (15 mph) ! I guess that the last one may be restricted to suit the european law, but...

Hi, I bought a Puma/Ezee kit from a German seller. First I had to exchange it because it was defective. Now I have got a functional one, with a 20A controller. Unfortunately, I feel quite disappointed, compared to what I have read about Puma, Ezee and BMC (don't know exactly which model is...

My sensorless controller is a Clyte. It works fine with both my NineContinent and Goldenmotor kits, very smoothly. I thought that the explanation for not working with the Puma was because when I launch the wheel to reach the ignition point of the controller (about 3-4 mph), in fact the freewheel...

Hi, I have got both GM and NC 6*10 motors. Used with 48V on a 28" wheel, the GM does 48 km/h on the flat whereas the 9C can't reach 40. On small hills, the difference is reducing, it seems that the balance is about 4% : on steeper hills, the 6*10 is a bit faster, and gets less warm. But it is...

Hi, I have a Puma kit that doesn't work well : it needs a reverse rotation to start, and then cuts off after a few seconds. It looks like a Hall sensor failure, doesn't it ? By the way, I used a voltmeter to test the sensors : one of them always shows 5.0V when manually rotating the wheel. So I...

I followed your advice, ordered A1302 and I will try it. Thanks a lot.

Hi, Since I am used to fry my throttles, I don't want to buy and buy again $25 throttles. I guess they only need a new hall sensor to work again. I was told that they are not the same kind of sensors as the ones used into the motor, so do you know what kind of sensor I should order ? Thank you.

Hello everyone, except for the Crystalyte controller, which is quite expensive, do you know another one that can handle both 36 and 48V, I mean about 31V mini and 56V maxi ? E-crazyman controllers don't seem to do this. Thank you.
