Re: Rental vs privately owned
It's a relatively easy bit of modification to make an electric bike that will go faster than 15mph, if you're capable of tinkering, but it shouldn't be done. If you really want to go faster than 15 mph, get a licence, an electric moped and insurance. Or alternatively, ditch the motor, and get a decent quality bike, which will be quicker than 15 mph after you've done a few weeks of riding.
