© 2018 Crosshead. A project by The Group Creative. All rights reserved.

The beginning

The first seed of an idea emerged in 2007, when Stuart Lambert was taking a break in Bruges, Belgium. Frustrated without a bike on hand he purchased a folding bicycle and discovered a number of performance issues. Believing there was the potential to create something better, he considered designing a bike which would satisfy the needs of a demanding cyclist yet still offer the convenience of a compact folder.

From 2009 Stuart and an experienced team of designers and engineers have developed the Crosshead bicycle through six prototypes to ultimately create this new challenger folding bike.

2009

Project started

Crosshead was founded and the project began, Stuart Lambert worked on the developing the initial concept for prototyping.

2010

CP01 completed

CP01, the first prototype was created by the engineering department at University of Greenwich as proof of concept.

2011

Patent granted 

Patent for unique Z-fold technology was granted.  

2012

CP02 completed

Working with JNDC an engineering consultancy, the CP02 prototype was created. With QR clamps, improved sand castings and early experimental glued and welded joints.

Continuing working with JNDC, CP03 was completed. With new internal front and back mechanisms this development prototype had an improved aesthetic and function.

2013

CP03 completed

2014

Moved to factory

Stuart Lambert moved into the new Crosshead factory in Kent to continue working on the Crosshead project.

2015

CP04 completed

Working with Alex Kalogroulis, a design engineer, CP04 prototype was completed. Comprising of evolved hinge mechanisms, secondary locks, investment castings and glued and welded joints.

2016

CP05 completed

Incremental engineering updates were made including, a new steering clamp, anti-flop wheel mechanism, redesign of several parts and improvements to the manufacturing process.This development resulted in CPO5, a pre-production prototype which at the end of the year was put through testing.

CP06 development was initiated and CEN testing was completed on the forks and folding steering assembly giving Crosshead a saleable bicycle by December.

2017

Passed testing

Complete CP06 bicycles are assembled for user review and a company launch at the ‘London Bike Show’ in February.

2018

Product launch
