I bought the Hitway BK3S and l've been having quite a lot of fun with it for the last few days. It has 3 speed settings that are L - 9MPH M - 12MPH and H - 15MPH and everything was fine until yesterday. Now L and M still work as intended but H is now around 20MPH, I don't know what I've done to uncap the speed limit but I want it back to 15MPH. I'm more concerned about the motor/battery exploding than anything, plus the bike doesn't have very good brakes so 20MPH is just to fast for me on this bike (also it's illegal l think in the UK)

Can you help me in my display Tell me everything about P01 to P16, at which low numbers they should be correct, they tell me, so that the engine runs well without failures

Do you know how to go onto settings above P08 (more specifically P10)? Mine goes back to P01 after P08. Thank you!

From the description, it is possible that one of the following three accessories may be at fault: 1. gauge problem, 2. controller problem, 3. battery problem. You can check to see if the meter is displaying a fault code. This will allow you to troubleshoot the problem based on the fault code.

hi, Even if I press the + and - buttons, "- - - -" appears and I cannot proceed to the settings. Please tell me the password. There was a problem with the display, so I replaced it with a new s866 and couldn't proceed. In the previous s866, you could proceed to the settings. The bike is ado a26s
