watmour Posted March 24, 2019 Share Posted March 24, 2019 Hi everybody, I have bought a Ninebot Segway es2 a couple months ago. Since yesterday, i have an issue with the frontwheel: it doesn't turn well. It's not locked completely, but it severely impede the turning. It doesn't allow to use it, because when i try to start, the system automatically switches off. It's like the electric brake is always on, even when the scooter is off. It looks like a software problem. What can i do? Reset it? Link to comment Share on other sites More sharing options...
pico Posted March 24, 2019 Share Posted March 24, 2019 My bet: Back EMF because of a blown MOSFET. In other words the wheel motor coils are shorted by a blown semiconductor. Happened on my X3 after GF oversped the motor. It feels like the bearings are frozen. Link to comment Share on other sites More sharing options...
