The Doohan iTank seems like a nice combination for an old rider. It has the added stability of two front wheels that articulate like a Jeep for off-read riding. This also adds braking and stability - something older guys need. It has 3 big disk brakes that are controlled hydraulically - not by cables.
It goes about 40 MPH with a range of 50 miles on a charge. You just plug it into a 110 volt outlet for a full charge in 6 hours.
It can easily haul two adults. The batteries can be charged in the scooter or taken out and charged in the home. The price is listed at $3500. Supposed there ia a company connected with Tesla - renting them out in Vegas.
