I was at the end of my sk8 and wanted to wear the battery down a bit before I put her back on the charger for the night. There is a small hill next to my house so I put her in GT mode and got close to full speed before arriving at the base of the hill. About halfway up the hill, the left motor made a weird sound. The best way I can describe the sound is it sounded a bit like the motor was skipping or something weird. I jumped off the board immediately and walked it the rest of the way.
Once I got to flat ground I picked up the rear end and tested to make sure both motors would spin. Both motors spun well but the one that made the noise spun quite a bit longer after letting go of the accelerator. Usually, both motors stop immediately after letting go of the accelerator. I put the board on the ground to do a short ride test and it was clear there was quite a bit of torque loss.
Any clues??? This was a brand new board on it’s maiden voyage. pretty disappointed.
