Co-Motion – Java Tandem

Find out what’s out there beyond the asphalt grid when you take a Java into the wilder parts of the globe. This great fitted with big knobby tires also can perform a more civilized role with a more conventionally sized 700x32mm touring tires for paved adventures.

“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.”
