fabio70mi Posted November 28, 2017 Share Posted November 28, 2017 Hi, on my 20 months old IPS121 I hear some clank noise. It happened sometimes, but now it's happening often and louder, Noise seems not related to wheel rotation, like valve stem hitting chassis. It sounds a bit like https://www.youtube.com/watch?v=85xpFryaVlY (not mine) when changing direction, but it happens to me when riding straight on. What could be ? I would like to open and find, but, I have not mechanical skills, lot of pieces are fixed with some glue to avoid vibrations, and don't want to spoil battery, so I'm a bit scared. Battery still last about 30km. I'm riding not to full speed, because I'm scared the wheel hangs bringing me to face off. Fabio Link to comment Share on other sites More sharing options...
The Fat Unicyclist Posted November 28, 2017 Share Posted November 28, 2017 Does it occur when you are accelerating / braking, or while you're riding at a constant speed? And does cornering cause it too? Link to comment Share on other sites More sharing options...
fabio70mi Posted November 28, 2017 Author Share Posted November 28, 2017 I think it happens also at constant speed. Cornering doesn't matter. I promised to me to record this noise with mobile, but didn't so far. Last time I was out with @Moltimondi and other friends and they were wondering about that clank noise Link to comment Share on other sites More sharing options...
Hunka Hunka Burning Love Posted November 29, 2017 Share Posted November 29, 2017 I wonder if it could be a slightly loose axle nut or some movement between the pedal support and the axle. Maybe they need to be tightened? Link to comment Share on other sites More sharing options...

Maybe they need to be tightened? Yeah, the example video sounded like movement somewhere between the chassis and body... Link to comment Share on other sites More sharing options...
fabio70mi Posted November 29, 2017 Author Share Posted November 29, 2017 Could it be one of many permanent magnets is detached from wheel and is moving a little inside its position ? Is it easy to open the motor ? Do I need special tools ? Anyway, I need to record a video and post here. Fabio Link to comment Share on other sites More sharing options...
IPS Malta Posted November 29, 2017 Share Posted November 29, 2017 Hi Fabio, you can also try spinning the wheel freely when it's turned off (careful not to pinch your finger) and see if you have any sounds there. If anything from the motor that should sound there. Will wait for your video though to say more about it. Link to comment Share on other sites More sharing options...
