Re: 120% setting on sensorless controller

Im using cellmans original clutch I think the key to keeping the clutches is to avoid "slamming starts" when the wheel is already turning in freewheel and you ramp the power, you can hear the clutch "clunk" as it engages, i decided that couldnt be good for it.. erm. cellman has put an additional shu...

Re: 120% setting on sensorless controller

Hi Mark

Mine didnt work either, I assumed again due to being sensorless

Also found that massively increasing the amps didnt seem to have the same whoosh

But great as a back up controller though :)

Re: Talk to me about magic pie (sounds like an awesome drug)

The pie uses the same windings on all sizes except the 16. normal 48V is 270 RPM, the 16 winds at 420RPM i believe

Very rugged, but internal controller has known issues, and amp limitations.....I have completed nearly 4000 miles on mine, just changed bearings now

Re: GM Controller Capacitor Help

My experience with this controller was that the jittery feeling you are getting is when the controller is getting too hot inside the wheel.....after longer distances it was more noticable.......in the end i just went with an external controller...so much less worry

Re: Reducing throttle by 10% using resistor?

The EU regs state... 250 continuous output maximum before the windings burn out....., so you cannot legally run a 1000w motor at limited amps the use of a button for "boost" or off road setting is considered not ,to be in line with "ebike" definition within the EU... Stupidly, the UK is the only cou...

Re: be careful with MagicPie (Spontaneous acceleration)

Hi :) I had this issue also, and its not really just a GM issue, but all cheaper motor kits There is a shared ground between all the connections...if this ground fails, the throttle rail cannot ground, and the ebrake wont work..... I think all the chinese manufacturers should at least wire the ebrak...

Hi Sunshine You are certainly getting around :lol: Truth is, the other controllers like the infineons are more powerful than the stock GM controllers, and are going to produce more noise than the GM controller as standard....the only option you have to calm the noise down is to lower the amps to the...
