Re: Mid drive vs Hub Motor for 10000 watt project

wondering how you are going to try and license and insure this once its done, mrcrash had the same problems. if 55kph is dissapointing on an bike designated to go 32kph then bite the bullet and get a motorbike, even a reasonable sized motorbike will do what you want, or build an electric motorcycle ...

Re: Frustrated Newbie cant get any power

did the xt90 have a green marking on it (they do an antispark version) otherwise even with power off at the controller switch one expects a spark. As previously mentioned you need a voltmeter to check the battery for output voltage before you even try to investigate further. saying it wont run on an...

Re: Supplimentary batteries for a ZEV scooter

why not buy a second charger and charge at work if able. 2nd choice and probably the easiest get a second pack the same as the 1st in capacity and either fix it somewhere and swap plugs over for the way home. that way you have a second pack and if one goes you still have your scooter. Yes you have t...

Re: Car replacement in London/Other Cold Weather

Middlesex, from around Greenford to around Hillingdon is served by great bike paths used by no one. Hillingdon/ Uxbridge is the end of the line for the train and its a slow painful tube into and across London, not as painful as driving though.

Re: Golden Motor BLT behaves strange

Have you played with the settings, like put it to 60 degrees. Or swap it to reverse direction. Also the voltage is only set at 24v. It reminds me of a hall sensor out or a phase wire mismatch.

Re: Is this a sine wave controller?

Re: Scooter Hub Rusted Inside

in my short time I have ascertained this. the controller is exactly that, your motor is only rated at a certain wattage, but probably will take more. The battery is simply a power source and it will 'sag' under load which is why you are seeing lights go out climbing hills. Most controllers have a lo...

Re: Is this a sine wave controller?

i have this controller. its 1500 watts peak, not a sine wave and probably only marginally better than a stock controller. there are some tried and tested controllers that can be had for cheaper and give the right power (sunwin and greentime for example) that will serve you far better.

Same issue, the incandescent on scooters has a live from the battery or 12v transformer to the earth pin and the switches swap the lower pins to earth. The dirty way to change this is swap the earth and main pins over on the headlight plug giving you normal lighting,but no full beam, other than that...
