Re: Mid drive vs Hub Motor for 10000 watt project

If you have the stock tires that are designed for e-bikes that will throw your balance out at those speeds. Fortnine.ca are pretty good at prices and delivery

Re: Unlock speed with lcd display

None of your links actually work so its a little hard to know exactly what you have. your guess is correct the controller will be the only way to unlock more speed (that and a lot more pedaling) but you are probably expecting a lot from a 36v 500w motor with an 8Ah battery. that will assist your ped...

Re: Mid drive vs Hub Motor for 10000 watt project

I’m with the controller to. Your battery is 3 times better than mine and I get easily equal your performance. The motor will do 75 km/h with 72v so any of the proven controllers (Kelly, power velocity, sabvoton) would probably do what you want. All should plug up to your CA. I wouldn’t go charging t...

Re: Mid drive vs Hub Motor for 10000 watt project

Something sounds wrong, Is the CA verifing your voltage/Amps because I would expect the increase in voltage to be pushing closer to 60km/hr. Its a super heavy bike but so are a lot of DUI scooters and they are going 60km/hr for 50km with pretty much an upgraded controller and good battery reserves a...

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.

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: 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.
