Disability Pavement Buggy -- Go Faster ?

[poynton]

Anyone know if it is possible to remove the 4mph speed limit on a disability scooter to make it go faster ?

I know that they modify golf carts in retirement villages for on the road use. They use special 8 Volt batteries in place of the standard 6 Volt ones.

My friend modified his mother's scooter to make it go slower, but I don't remember how.

Everything is possible. Or was the phrase "nothing is true, everything is permitted"? Anyway, the question is how the speed is governed. I suspect the motor controller has some way of knowing the RPM, then saying don't go any faster. The actual limit could be set with an analog trimpot, or in firmware. There might also be a simple setting (jumper?) to enable speed limiting. It's possible there's a speed limiter that operates independently of the speed controller and can shut down the power in case the speed control fails in a wide-open-throttle mode.

A place to start would be to identify the motor controller and google for information. People may have been hacking them to use in fighting robots, R/C models, or small electric vehicles like e-bikes or motorized barstools.

OK Andy - why? What mischief are you up to?

UK chariots are limited to either 4mph or 8mph.

I have seen one imported from the states with a speed of 12mph.
