  1. Dear Qmwheel,

    I have the V20 and I have a few questions:

    – P03 01: Can I change the maximum speedlimit for example to max 28 km/h?
    – P04: When P03 01 is on I can change P04 for example to 28, but maximum speed is not changing to 33 km/h
    – P06 01/02: When I chance this setting the bike give error E 20, how can I fix?

    – Can I install the throttle to maximum speed 6 km/h? That’s legal in The Netherlands

    – The PAS response very slow is it possible to get it faster?

  2. My display doesn’t show when I switch on my head light nor when I use my turning signals. Does this need additional wiring from the unit on the steering wheel to the display? Or is there just something wrong with my display?

    • Hi Grizzly, does the cable connection correct? If the cable connection correct, you display might have problem, please contact the seller get replacement parts.

    • From day one these things don’t show up in the display, i have put a new display on, and the signals and lightin the display still not working, mayby new update of the software???

    • This happens when you have the settings set to where you NEED a gas padel. The most probable fix is to put setting “P6” to 0. This should fix the error code
