Hello people ,
Any one ever owned one of these
Can only find very limited info about these thru AliExpress
It's a 1500watt peak mid drive
Not sure what amp is thru the controller
Or type of capacitors it has inside the controller

All I know is that it's a 48v ,28ah battery pack
Finding the actual motors rated wattage at 48v x amps in the controller is a guessing game really ?? True or not ??
I remember seen a while ago that it's a 400watt rated motor continuous , but I could be wrong

Any feedback would be great
And things pros and cons to lookout for
I'd love a little bit more top end speed
It apparently hits 50kph another 10kph extra would be great
I know adding a extra 12v might do that
Anyone ever upgraded this model ebike

Thanks
Happy to add more pics if anyone wants
