Can anyone maybe shed some light on this one before I get irritated enough and rip the hub assembly apart? I own a kasea ze2000 modified, the one with replacement batteries now working quite well that was documented earlier in this forum. This is the last irritation I'd like to get rid of before I consider my ev project complete.
When the back wheel is hoisted off the ground and I hit the throttle, you get the normal quiet whine of an induction motor, I'm good with that. However, when then rear wheel is on the ground and you hit the throttle there is a very annoying clicking noise, similiar to a gas engine noise. This only happens when you provide power to the motor. When just pushing the bike or moving it with your legs whilst you ride it, you don't hear it.
It's been like this since I got it. I imagine kasea put some sort of mechanism in the hub assembly to make it sound like a gas engine so people could hear you coming down the road. The
only problem with this is:
IT'S NOT A GAS POWERED SCOOTER! If I wanted to hear loud farting noises coming from my bike, I'd buy a harley. Can anyone provide any ideas about this fairly loud irritating noise? It's really getting under my skin.
