Co-Motion – PeriScope Torpedo Tandem

This tandem is ideal for getting your young child started cycling early, yet can stick with your family as your child grows and take you places you never imagined.

“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 PeriScope 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.”
