The non-electric Montague Paratrooper is used by the US military. This version with the BionX electric bike kits can be found at http://www.greenspeed.us/bionx_montague_paratrooper_electric_bike.htm
I like this idea. You could fold it up and take it into work with you or even on a plane when you travel. At the Montegue web site they have bags that you can put the bike into to transport or store it. http://www.montagueco.com/bikes/accessories.html
