I believed that they did do some exaggeration.
It may well do 100 MPH, but it won't do 100 MPH and have a 60 mile range.
Low tech? I don't think so. Just because it uses an integrated controller module and Charging system - I would not call it low tech. On the contrary. When considering the very basic ICE world of Choppers, this is a very hi-tech piece of work.
