http://www.newwheel.net/vektron The Tern Vektron combines a serious folding commuter bike and the more powerful Bosch Performance Line (Gen 3) drive system to create a bike that customers have been asking for: a folding electric bike with ample power and a ride quality that defies logic - the Tern Vektron rides like our favorite electric bikes, it just happens to fold. Vektron is ideal for carrying small kids, fitting a wide range of riders, or as a "first car" for teenagers looking for more vehicular independence.
