The world's fastest mobility scooter just did 107 mph.

The mobility scooter your grandparents ride around the house and the supermarket top out at around 10 mph — if they’re lucky. This one, though, just did 107.6 mph.
Built in just six months by mechanics David Anderson and Mathew Hine from the UK, this highly modified rascal broke the world record for a mobility scooter on Isle of Man last week.
In accordance with Guinness World Records regulations, the scooter was based upon a commercially available mobility aid. The two stripped down a ‘Days Strider’ mobility scooter and modified a racing go-kart frame to fit it. Clearly, the original frame was never going to be able to handle 100+ mph. They then replaced the snail’s pace electric motor with a 600cc Suzuki Bandit motorcycle engine.
After it’d been fully assembled and sprayed with a bright-green paint scheme, the two took it to the Jurby Motodrome on the Isle of Man and smashed the previous world record of 82.67 mph set in 2012. With Mathew in the hot seat, the scooter averaged more than 24 mph above the last record-setting scooter.
Unfortunately, the men’s ingenious and more than mildly terrifying design will never make it to old folks’ homes — or even the road, for that matter. That’s because the thing has no front brakes, which makes it illegal on public roadway, which is sad, really. I was hoping to see some blue-hairs burning serious rubber on the way to bingo.
