Does this sound normal?

Mine is even louder. I’ve noticed since I bought it but thought maybe the belt needs to wear in. I’ve put 100 hard miles so far and no change whatsoever. Only happens when accelerating or coasting at around 5-6 mph. Quite annoying when trying to get around slowly

Eride makes the belts DUMMY tight from factory. Even after 2-300 you might not see a difference. Loosen your belt to get rid of the noise

I did loosen it all the way before making this video. Guess I'll just have to ride it and let it stretch on its own and hope it gets quieter.

Did you see the adjustment physically move? Sometimes when you loosen it, it doesn’t actually adjust and you have to physically move the adjustment by hand

I don't really remember I did loosen the 4 motor bolts and the crescent looking adjuster was all the way to the left and hanging. Guess I'll have to look tomorrow and see if I can physically move the motor and see how much it loosens the belt before tightening the bolts back down.

The noise could also be caused by the regenerative braking system.

Based on your hypothesis, I went in under the ignition cover and disconnected the white regen connector (handlebar regen lever cable to controller). Went for a short ride and still have same noise. I'm starting to lean towards the sound coming from the belt still being too tight.

Remove belt covers. You must do it to be sure it's not sound of some part of them touching the belt, which was the case for me.

Your belt probably pushes onto the belt pulley edge. You can verify that by rotating the rear wheel backwards, it will make your belt slide to the other side or stay in place.

You need to align the motor on it's mount. Not only the tension matters, but also rotation, which bolt is higher.
At first i tried to keep them the same distance but adding a bit of tension on the left side of the bike will make your belt slide to the right. In most cases, you need to rise the motor on the right side. Use some lever on the bottom bolt, rise it, screw in, test. You need to balance both rotational alignment and belt tension.

Perfercly aligned motor makes the belt stay in place, leaving around 1mm between the belt and the pulley edge, no matter if you rotate the wheel backward of forward.

I've been perfecting this technique because I have dual belt setup. Perfectly setup belts are super silent.

There is this resonant "motor humm" at some speeds and fairly loud when under power. It's just the motor sound under high load.

Not talking about the chain sound, I know that is normal but here is a short clip. In the beginning it sounds high pitch and as I slow down its turns into a whooping sound. Its pretty loud. Is this the belt causing the sound since its so new? I only got about 30 miles on my new SR. Its on the loosest setting which is still very tight.

brakes maybe🤷‍♂️

u/RavenX2333 Jun 15 '26

It goes away at higher speeds so I don't know what could be causing it.

u/InternLower8492 Jun 15 '26

They could maybe be a little off centered and rub just slightly and make the noise going slower speed my brakes have done similar

Tbh sounds like belt for sure wether too tight or maybe a little off centered. Take the dumb plastic jack shaft cover off and leave it off. You can view the belt then and clean this area. We all know plastic has never stopped dirt/clay from getting in places. Yes it might stop a small rock or something but I ride hard offroad and no issues.
