No ebike is perfect, this is a thread dedicated to sharing known issues or problems with electric bikes from Daymak as well as any help and solutions you know of. Sometimes that means a DIY fix and other times it can mean a recall, software update or part replacement by a dealer.

Please be respectful and constructive with feedback, this is not a space for hate speech. In many cases, representatives from the company will see feedback and use it to improve their product. In the end, the goal is to enjoy riding and help each other go further and be safer.

I'd like to know if anyone has figured out if it's possible to program the 1/2/3 Speed limit switch with different profiles.

I'd like a 15mph limit mode for when I'm in a bike line and a unlimited mode for when I'm in the street with cars.

I have just purchased a new daymak ec1 advance. It worked for exactly 2 seconds before failing. The digital screen reads a flashing " Err 24".
Does anyone have any advice or suggestions?
Terribly disappointed.

Does anyone know why the 123 speed switch won't show up on the display? Everything else lights up on the display except for the part that shows what speed is selected. Any ideas? I am driving the daymak kingston.
