Don't have controllers as they were sent to the seller and have not returned. Therefore, the Info on the controllers is not available as they were shipped out. But all addes state 1500 watts.
Euro Terminal Connector
I isolated the problem to weak wire connectors on the two scooters and now they are both working fine. Soldering or better yet using terminal blocks to connect the controller/motor wires did the trick. Being more familiar with them now, and being able to get parts from Miami, I'm glad I stayed with them as they are absolutely terrific off-road scooters. We us them in a rural setting on gravel roads, paved trails and ATV trails. Having the larger tires 12" rim tires (actually 16 inch diameter tire) they ride very nice. We also have a 1600 Watt 48 volt Uber Scoot. Its nice, reliable, but gives a bumpy ride. Whereas the Hyper-Racing 1500 Watt 48 volt off-road scooters ride exceptionally nice. This is a scooter designed for adults. So now I'm all set and appreciate all of the recommendations and assistance passed on to me.
Robert, This information is priceless and instrumental. I own the exact scooter, it did the exact same thing. I've spent countless hours troubleshooting and researching finally this helps solve the issue for me! (I hope) I'm going to solder them directly and give it a shot. Again, thanks and feel free to show me how your scooters look now after you soldered the connection. I'm in Coconut Creek and i use mine to hit all of the local parks with my Wife & Daughter and they ride the EVO 100 but i stepped it up to a T-Walker 1500 y Hyper Toys because i weigh 220 Lbs.
