Started to disassemble my board that caught fire and found something totally unexpected. Spun the drive wheel by hand and noticed it quite wobbly. Took the wheel off and found some of the spokes had broken. Took a look at my other wheels and all of them seem fine. Seems like these wheels can't be used for e-boarding. The plastic they use must be different from what is used on the Abec 11 flywheels. Has anybody else had similar problems with these wheels.
