    Sur-ron creaks when breaking front - Stem bearing??

    @calab: So you think it's simply "normal"? Any Ideas how to fix it anyway? Maybe I can finetune the out of specs, if it's something adjustable.

    Sur-ron creaks when breaking front - Stem bearing??

    @amberwolf: But how can the tube itself creak? The clamps to the stanchions? Where do I find them? How to they look like? I am not this familiar with this part of the bike. Do you have a picture or anythink that helps? Thanks Timo

    Sur-ron creaks when breaking front - Stem bearing??

    Hi, my Sur-Ron creaks when breaking strongly with the front brake. The creaking noise comes NOT from the brake. It comes somewhere from the handlebar bearing or next to it. I already checked the stem bearings but found nothing wrong (see pictures in video). Also set the bearing clearance but...

    Cyclon 3000w Motor Problem

    OK, I checked all the wires. Also I checked the hall sensors again. It seems there is a problem with one of the hall sensors after all. Does anybody have the specifications of the hall sensors? I need to buy a new sensor but I don't know the exact type. The whole board seems not to be available...

    Surron throttle not usable for slow speed

    throttle zero is fine. No need to change this. Is it possibble to switch to torque command with the x controller? Or is the only way to try another throttle. Do you have any recommendations for a good one (thumb or wrist)?

    Surron throttle not usable for slow speed

    Do you know any thumb controller compatible with the surron? I searched but did not find one with is definitly working. I am able to solder cables. No problem. But the voltage an signals must be compatible with the surron.

    Surron throttle not usable for slow speed

    Thank you for the reply. This is exactly what I am experiencing. I really thought the x-controller is smoother compared to the standard controller. Or was that issue even worse with the standard controller? Or was that issue introduced with the digital wrist throttle? In the past it was a cable...

    Surron throttle not usable for slow speed

    Hi, I purchased my surron a few days ago. The 2021 street legal model. I life in germany. It's limited to 45km/h. It has the X-Controller. Overall the bike is good. I expected a bit more range from the battery. But anyway. But a real big problem is the throttle. It's ok for idle and full...

    Cyclon 3000w Motor Problem

    Hi, thanks for the reply. Unfortunatly I do not have the possibility to swap controller/motor. I have only this bike, nothing else. Also I don't have a buddy with a similar bike around. Your idea is good. I will swap phases and play around with the cables a bit more to eliminate most sources of...

    Cyclon 3000w Motor Problem

    I don't notice any smell. It smells like elektroniks. No really burned. But what is that black ash (last photo) The dark spots seem to be ok. Nothink burned through. The resistance of all 3 phases is 0.1 Ohm. All of them. No matter which direction. Is that normal for such a motor? When...

    Cyclon 3000w Motor Problem

    Hi, I managed to open the motor. It looks ok to me. There are some small black spots. I don't know if that means anything. Instead of posting several photos I made a 4K-Video of the motor. What do you think about it? https://youtu.be/nTHF-tGoBQQ cheers Timo

    Cyclon 3000w Motor Problem

    Hi, no, max input is 2450w with a 60v battery. But it gets hot if running this current for several minutes. Normally I check by hand the temperature of the motor. If it's too hot to touch I let it cool down. Normally the hall sensory overheat first - but I am not sure. I will open it up and post...
