 The Bickerton was a portable bicycle launched when folding bicycles tended to be step-through frames with a simple hinge, such as the folding variant of the Raleigh Twenty.The bicycle was made entirely of aluminium profiles, without any welds.In its weight (under 10 kg) and folded package size it broke new ground
 and it is cited by Andrew Ritchie as one of his inspirations in creating the highly successful Brompton bicycle.
