Innovative Geometry

There have been attempts to break from the traditional “double diamond” design that has graced bicycles for more than a century. But Italian designer Paolo de Giusti has created something truly revolutionary.

The XXXVI DG features the standard frame shape but with a unique twist that seems almost like an M.C. Escher painting. The result is an asymmetric frame that features an overlapping frame and fork, along with unconventional placement of the chainstay. This concept bicycle – and let’s be honest this will likely never see mass production – features 36-inch wheels, something that was once common once.

This bike has everything a bike should have. Two wheels, pedals, fork, frame, seat. But de Giusti has put together in a way we really haven’t seen before. What’s not to love?

Plastic Fantastic Clear Frame

One thing is clear about this bike, the frame! The German designed Clarity Bike does indeed evoke the thoughts of “clarity.” While obviously a concept bike, the folks at DesignAffairs could be on to something with this bike, which is constructed of Trivex, a transparent polymer commonly used for aircraft windscreens. If it keeps the wind and bugs out of soldier’s hair it must be good enough for a concept bike.

The result is a lightweight bike frame that can hold up against impacts and even extreme temperatures. As with carbon fiber it could probably result in some aerodynamic shapes that titanium, steel and aluminum can’t deliver, but unlike carbon fiber it could be injection-molded – and more importantly could be recycled if damaged.

Concept Ride – the MiniMum

Small concept bikes apparently on some designers’ minds. Last week we heard about the Bicymple, a small chainless bike. This week we were treated to word on the MiniMum, from Omer Sagiv, a city bike that is crafted from aluminum tubes and which uses a wire cable support with flexible tension to add stability.

The MiniMum used a back pedal break along with a Kevlar belt instead of the chain to reduce maintenance on this city commuter. It is reportedly fixed gear, so we’re not sure how that will manage in traffic, and since this bike doesn’t appear to fold we’re not sure if many office buildings would actually allow riders to bring it in.
