I didn’t even know what a Racerunner was when Hannah approached me to build this – it was an interesting learning experience, though, and worked out half the weight of her previous one. It also splits in half for transport.
Four-Person Bicycle
This was a rush job – a four-person bike built in two weeks for a marketing roadshow.
It had S&S couplings fitted to make it a little easier to transport, and a beefy stand to hold it upright with four people sitting on it.
Bernard’s Recumbent Tandem Trike
Bernard wanted a recumbent tandem trike for riding in Cumbria.
The frame was made from mostly 4130 chromoly steel tubing.
S&S couplings allow it to separate for transport.

Colin’s Tandem Trike
Colin wanted a tandem tricycle, but using a standard Rohloff hub gear, in a tadpole instead of a delta configuration for stability.
The frame was made out of Columbus steel tubing, triangulated and braced for stability.
Gavin’s Racerunner
Gavin’s Racerunner was built from thin-wall Columbus Gara tubing, for a frame weight of around 4kg, and a total built-up weight of under 10kg.
The frame was built on a custom jig to be perfectly straight, and has adjustable fore and aft positioning of the saddle, and adjustable chest plate using a seatpost.
A series of axle inserts allow different wheels to be used, and the camber can also be adjusted.
Cost was £1500 for the frame, inserts, painting and assembly.
Circe Helios Rohloff Tandem
I just finished building up this bike – the Helios is a very adjustable aluminium frame, and with the removable seat posts and stem it also packs down very well.
For this one, I had the frame repainted, and fitted a Rohloff hub and Hope disc brakes.

With 4″ tyres, the Pugsley is built to happily trundle over snow, sand, gloopy mud, small children, and pretty much anything else you point it at. This one has a Rohloff 14-speed gear in the back, and a SON Delux front dynohub powering an 80-lux Edelux light.

Built for a child with special needs, this will tow behind any bike using a standard Chariot hitch – just finished it off today after a manic weekend of building…
