Java Rohloff

With its ultra-rugged frame and big 29” wheels, the Java is equipped to take on extremes. Getting away from vehicle traffic has never been easier or more fun. The Java’s rugged frame and specially-built fork are designed to get you to your most exotic destination grinning widely. This great-fitting tandem with big tires can also perform a more civilized role with conventional 700x32mm or larger road tires.
  • Co-Motion-design super-sized zonally-butted cro-moly tubing.
  • Excellent choice for touring with the 29” wheel’s amazing versatility.
  • Plenty of clearance for large tires and fenders.
  • Front and rear racks mounts.
  • Can be equipped with 700c tires for road rides when riding “civilized”- disc brakes make it easy.
  • Larger than life hand-built 29” tandem fork.
  • Hand built wheels with Rohloff Speedhub with 14 internal gears.

  • "Took the tandem on an awesome ride this weekend. 130 km in two days. Got up some trails that really a tandem has no place on... rocky single track, lots of mud, steep climbs. The Java does it all, and all with my 7 yr old son on the back enjoying every minute of it! I seriously love this bike." - Simon D.
