In 1997, Montague won a two-year grant from the Defense Advanced Research Projects Agency (DARPA), who recognized the importance of the folding technology, to work with the United States Marines in developing the Tactical Electric No Signature (TENS) Mountain bike.
For this project Montague developed a new folding design, enabling the bike to fold faster for Paratrooper exit from military aircraft while also increasing its load bearing capacity. This gave rise to the Paratrooper, Montague’s non-electric Military Mountain Bike.
