Hello, I'm new here. I have a MotoTec Knockout 1000w/48v Fat Tire Electric Scooter. Today while riding, out of nowhere my rear brakes fully engaged and the scooter came to a hard skidding stop. I thought they froze up? But after getting off the scooter to try and figure out what was going on they seemed to disengage on their own, about 30 seconds after? I rode home slower than usual because I was concerned that it might happen again, and... it did one other time. I can't understand what would cause this? Does anyone have any ideas? It has hydraulic disk brakes. I'm wondering if it wasn't the brakes that locked up but was the motor because the motor is located in the rear wheel? The scooter is equipped with an automatic safety switch that automatically turns the scooter off due to over heating or other issues and can be reset with a button located on the battery compartment. The scooter did not turn off when this happened.
Also, I got new batteries back in October (4 - 12v Lead Acid Batteries) and the charge does not last very long, at all. I can go about 3 miles and the battery indicator will drop to zero when I turn the throttle, then shoot back up to 100% when I let off the throttle. The scooter will still operate but goes about 6MPH slower when the batteries fail like this. (The max speed of this scooter is only about 18MPH when fully charged and operating normally, and normal range is about 10 miles when fully charged.) I noticed that if I go somewhere 2 miles away, then come back right away.. the batteries perform better. But, if I go 2 miles away, park it for 1-1.5 hours, then ride it the 2 miles back, the batteries seem to drain to zero when I'm halfway home. Not sure what's going on? Did I get ripped off on my new batteries? The batteries that came with the scooter when I bought it lasted about 2 years before they started to fail, like these batteries are failing. I'm wondering if it could be some kind of electrical component that could be causing this battery performance issue?
