Assume everyone else is an idiot and out to kill you.....I'm always amazed at the number of people walking/cycling around who are quite happy to trust other people with their safety, personally I wouldn't trust a soul
It's a more advanced system than that. It uses bifocal light sensors coupled with an intelligent*, self aware and self learning data processing unit to detect when pedestrians are in proximity to active the noise generator. The system is portable and can even be powered by a varity of energy sources although there have been concerns about the units high consumption of the dangerous and sometimes deadly chemical dihydrogen monoxide.Which operates all the time below 18mph?
I doubt it's a different motor, but you can get a simple de-restriction device which ups the power to allow speeds up to 28 mph.The reason he’s legged it is possibly because he’s fitted it with a larger electric motor than is legal in the U.K. Effectively driving an unlicenced, unregistered, untaxed, uninsured motorbike. There are more of these thing appearing on the streets to get around the associated costs of motoring with riders thinking they’ll never be stopped as it’s pretty impossible to detect without an actual stop and search.
