I notice my bike makes a rough sounding noice when barely applying power, like when I’m riding with my son. On the stand where I can spin the wheel freely, if I very slowly rotate the rear wheel, there’s a pretty rough feel and sound coming from the electric motor area. Is this normal? I’ve got a vid, but figure I’d just ask first before having to post it to YouTube to then link it here. Thanks in advance!
PS I know the chain is tight, I’m in the process of adjusting it now 👍

You will hear a lot more noises compared to normal dirt bikes. Without the ICE engine you will pick up on chain noise, chain slap, cogging and a "darth vader" type noise which is the switching noise coming from the inverter. All are normal. EVs are the best!

Yeah, both mine sound like rock crushers when I'm barely creeping along. Although I swear my MXR is a bit worse than the MX. Going to take off the side cover when I change the gear oil this weekend, I think. I was going to check for that loose bolt that was recently posted about at the same time, I guess.
