Rake Posted December 29, 2020 Share Posted December 29, 2020 (edited) Hi All, we have a quite new E+ with some 50km on it and it recently developed an issue when it comes to a stop there is a rotational judder coming from the unit. Any ideas would be welcome thanks Edited December 29, 2020 by Rake Quote Link to comment Share on other sites More sharing options...
Paradox Posted January 2, 2021 Share Posted January 2, 2021 (edited) I have heard of this problem in the past with other wheels. It might be from a cracked inner shell. Or a loose power control board. Edited January 2, 2021 by Paradox Quote Link to comment Share on other sites More sharing options...
mike_bike_kite Posted January 2, 2021 Share Posted January 2, 2021 As Paradox says, it's usually just a loose control board so just check for any loose screws in that area. Also check there aren't any loose bolts on the pedal hangers. This video shows where the screws are on the motherboard. Quote Link to comment Share on other sites More sharing options...

Went out on it today and it only happens on decelerating. there is no reboot or shut down. I’ll check board connections tomorrow and report back Quote Link to comment Share on other sites More sharing options...
Rake Posted January 3, 2021 Author Share Posted January 3, 2021 Checked all connection and they were fine. Board firmly in place too. pretty stumped 🤔 Quote Link to comment Share on other sites More sharing options...
litewave Posted January 3, 2021 Share Posted January 3, 2021 (edited) Don't panic; it should be fine. This happened to me on my first E+ a couple times during the first 1-200km, as well as a strange grinding noise that occurred on two occasions. It did not happen again in eight thousand kilometers, and the wheel has been rock-solid and reliable.

Rake Posted January 5, 2021 Author Share Posted January 5, 2021 Well I think I fixed it - recalibrated the wheel and now it seems fine 2 Quote Link to comment Share on other sites More sharing options...
