Hummingbird tips scales at 6.7kg and is being made by Oxfordshire-based Prodrive
One of Britain’s leading companies in the motorsport sector has joined forces with the creators of a successful Kickstarter campaign to launch what is claimed to be the world’s lightest folding bike – tipping the scales at just 6.7 kilograms.
Banbury, Oxfordshire-based Prodrive works alongside car marques such as Aston Martin, Mini and VW in rally sport and motor racing and, with Subaru, helped Richard Burns and the late Colin McRae win World Rally Championships. It is also active in sectors such as composite materials, where it supplies the automotive, aerospace and defence sectors, among others.
Now it is helping bring the Hummingbird folding bike, originally designed by London-based Petre Craciun, to market, with its composites division re-engineering it ahead of it entering production.
Conceived to minimise weight to make it more portable than other folding bikes, the Hummingbird also has what is said to be a unique folding mechanism that keeps the chain in tension once folded, and also allows it to be wheeled along the ground.
Hummingbird has a unique and simple folding mechanism in which the trailing arm pivots around the crank. Unlike other folding bikes, this ensures the chain always remains in tension, even when fully folded and also allows the bike to be wheeled along the ground.
Our tech editor Mat Brett explains how it al works in this article published when the Kickstarter campaign launched last November.
