About

Sump and Spoke is run by Little Jam Jar Ltd.

Pieces. Mechanics and riders record them and send photos. We edit. They approve the edited version before it is published under their name.

Frame builder. Design a custom bike in 3D, from the frame geometry to the engine, the bodywork and the controls, save it under your name and share it in the gallery. The spec sheet it exports is for talking to a builder; it is not a drawing.

There are no stock photographs, no generated images and no tracking scripts. Road and Bench are two colour schemes for the same pages; the switch is remembered in your browser only.
