Co-Motion – Java Rohloff Tandem

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.

“Our Tandems are all built to your own specification, starting from £1600 for the minimum required equipment to then add onto any of our Tandem framesets.  The final equipment price will depend on the style of the complete Tandem.

The Co-Motion Java frameset prices are shown in the blue column on the right.

All of our Tandems accept racks, mudguards and our regular builds include some of the following equipment choices:

SON dynamo with USB charging, Belt drives, Shimano Di2 and Sram E-Tap transmissions along with Drop & Flat bar controls for Rohloff.”
