Universal lcd display

Lukasso · Mar 28, 2021

Hihi.
Trying to conect one of those universal lcd speedometer.
Voltage is working and i see speed corectly only when i spin the wheel with pedals but anytime i apply throttle it goes right up to 60km/h and stay there until released throttle.
How can i resolve this?

What is the exact wiring you have for the speedometer input, from your ebike system, and exactly what motor and controller are you using, and how does the motor drive the wheel?

What is it using for a speed sensor? If it's coming off a motor hall, the voltage may be out of range.

of course. That's what i want to find out myself.
when connect to hall wire we see 0 speed increase, value on display does not change when riding.
when connect to phase wire than speed increases in increments, 20, 50, 70, 99.
