Keep the Gotway quiet

The buzzer on my Gotway 14″ MCM 2S 340Wh is very loud. It’s a piezzo device, powered by a 25% duty cycle 3.3 khz square signal. The signal’s amplitude is 65V (the battery voltage !), no wonder it’s loud, and super duper annoying for you and certainly much more for pedestrians.

Unfortunately, as it has been said at length on the forum, the buzzer can’t be cut off because the GW has no tactile warning like tilt-back or vibrations on any other wheels. Without the beeping, you can overspeed (which can happens even at… 6km/h when the battery is near flat) and then, the wheel WILL shut the power down and throw you off. Yeah, as unbelievably stupid as it seems, it’s totally true : the wheel shuts the power down when riding to… protect you, nice logic, no ?

To reduce the volume and to make a Gotway ride more bearable, I don’t do the 100 Kohm potiometer-series-connected mod, it’s has been out there since the Gotway exists as a testimony of the super duper annoying buzzer (Gotway, please, do something !!!).

Here is my way to tone down the buzzer : a screw.

    Hey,

    What does that small screw do? Does it actually make the sound slightly quieter? And it should be placed exactly where you have it, below the center? Thanks!

      the sound is more or less reduced depending on how tight you screw. Screw at the same distance from the center as in my picture, angle is not important. A screw at the center is ok too, just less pratical to do.
      Apply hot glue once you get the desire level.
