Military-funded projects often pave the way for a much better consumer product, and although the original DARPA funding of the development of the Tactical Electric No Signature (TENS) Mountain bike for Marines and paratroopers is now over a decade old, hold onto your hats folks, because the design has been upgraded and will be sold in limited quantities with a 1000 watt propulsion system. The TidalForce M-750 x2.0 is based around the commercially available (and ingenious) Montague Paratrooper folding bike but has a top speed of over 30 mph and range on a single charge is 25 - 28 miles, using the electric power only. The E+ advanced propulsion system features nine forward power modes, nine resistance (exercise) modes, cruise control and anti-theft. It folds to 3 x 3 ft, so it fits in the boot, and the componentry is first class with RockShox Tora 302 Forks, Shimano XTR brakes, FSA Gossamer 30/38/52 tooth crank set, Crane Creek Thudbuster ST seat suspension and a WTB Speed-V Seat. Like we said - highly-desirable.
