Ex­pand­ing bike frames

BEN COXWORTH ex­tends his reach on frames from Hick­man and Brook­ly­ness

The Witness - Wheels - - BIKING - — Giz­mag.

TWO bike frames from op­po­site ends of the At­lantic dis­played frames that prom­ise to fit all hu­man body shapes at the re­cent North Amer­i­can Hand­made Bi­cy­cle Show in San Fran­cisco.

From the UK, frame- builder Mike Hick­man cre­ated the Hick­man Bike, which Hick­man says will fit any rider off the shelf, and will also be able to adapt to dif­fer­ent types of rid­ing.

Sec­tions of the frame tele­scope or pivot over a wide range and the han­dle­bars move for­wards or back­wards.

Only the head tube an­gle, chain­stay length and bot­tom bracket drop can­not ad­just.

The frame is made from TIG-welded chro­moly steel. Hick­man is ask­ing £ 2 000 ( over R43 000) for a frame, with­out wheels or sad­dle.

In the U. S., New York Ci­ty­based Brook­ly­ness built a Uni­ver­sal Bike for the one- frame fits all so­lu­tion.

When they first get the bike, rid­ers start by en­ter­ing their height and weight, along with the length of their legs, arms and torso, on the Uni­ver­sal Bike app.

They can also se­lect their de­sired ride style, from a list that in­cludes road, tour­ing, ur­ban, fixie, com­fort, pista and hy­brid.

The app re­sponds by dis­play­ing the num­bers that the bike’s frame length, seat height, seat an­gle, han­dle­bar height and fork an­gle should be set to.

The bike it­self fea­tures a car­bon fi­bre frame and fork, 24inch wheels, and the buyer’s choice of a Shimano Nexus rear hub trans­mis­sion ( in three or seven speeds) or a sin­gle- speed/ fixie con­fig­u­ra­tion. The make of most of the other com­po­nents is un­spec­i­fied at this point.

The whole thing weighs a claimed 6,8 kg as a sin­gle- speed, or 8,6 kg with the Nexus hub.

Brook­ly­ness is cur­rently rais­ing pro­duc­tion funds for the Uni­ver­sal Bike on Kick­starter. As­sum­ing the fi­nan­cial goal is met and things go ac­cord­ing to plan, a pledge of U. S.$ 895 ( over R13 600) will get you a sin­gle­speed, with $ 1 195 for a three­speed and $ 1 695 ( over R25 800 for a seven- speed.
