2015 Montague X90 folding bike

Military Tough

The X90 is one of several bikes based on the Paratrooper folding bicycle, the bike that built Montague's reputation for producing incredibly durable folding bikes. Designed with a grant from the Pentagon so troops could move in silence behind enemy lines, the Paratrooper was made to withstand the impact of being dropped by parachute (hence the name). Thus, the X90 is a folding mountain bike you can take on punishing slick rock trails over the weekend and pot hole pocked urban streets during the work week.

Standardized Parts

The Paratrooper rides like any hard-tail mountain bike with a suspension fork, using standard mechanical parts that are available in virtually any bike shop. When you eventually wear out a tire, brakes, etc, you'll have no problems maintaining it.

Military Frames W/Better Components

Like all Montague mountain bikes, the frame on the Paratrooper is the same as those used by the US military for close to 20 years. Made to withstand high altitude parachute drops, these frames are exceptionally sturdy and can endure riding on any surface. What sets the X90 apart from the Paratrooper are improved components like a lock-out fork with more travel, more gears, better derailleurs and better brakes.

How It Folds

The frame is composed of the rear triangle and a single, oversized top tube. The top tube is pressed onto the seat tube. Open a quick release and bearings within the top tube allow the front portion of the bike to swing back against the rear wheel. Remove the front wheel via the preset Clix quick release and the bike can fold to less than half its unfolded size.
