EVO Urban Utility Bike lets cyclists
swap clip-on accessories


This bicycle by a team of Californian designers features a frame with two symmetrical connection points, allowing cyclists to customise accessories attached to the front and back (+ slideshow).

The EVO Urban Utility Bike was designed with residents of San Francisco in mind, by a local team including industrial studio Huge Design, bicycle specialists 4130 Cycle Works and engineering agency PCH Lime Lab.

The collective came up with a bicycle that can be customised with various detachable accessories, including trays, saddle bags and child seats, that can all be clipped on and off the frame using a spring-loaded mechanism instead of being permanently bolted on.

"Current commuter bikes have bolt-on solutions for rack accessories making them more permanent," Huge Design partner Chris Harsacky told Dezeen.

"One thing we noticed is the amount of empty child seats that are on bikes around the city. Our frame allows the user to quickly change out an add-on without picking up a wrench."

A standard diamond-shaped bicycle frame has been manipulated to accommodate the connection elements at the front and back, forming one larger and one smaller triangle.

Intended to reference San Francisco's towers and bridges, the symmetrical frame is designed to support cargo loads at both ends.

Metal tubes are connected by 3D-printed steel lugs, which allow for quicker assembly than welding.

The front fork locks so the handlebars can be leant stably against a wall for loading and unloading.

Front and back lights, along with a cable lock, are integrated into the frame.

Hybrid tyres suitable for both road and off-road use are covered by mudguards.

"There are several trails within pedaling distance of San Francisco," said Harsacky. "We wanted this bike to be able to take advantage."

"The EVO Urban Utility Bike is the perfect example of designers coming to us with a concept, and together we engineered a solution – a bike that is not only beautiful aesthetically, but works to advance urban mobility within our community," added PCH Lime Lab co-founder Kurt Dammerman.

The bike was designed as part of creative platform Oregon Manifest's Bike Design Project, for which teams from five US regions were challenged with producing the "ultimate urban utility bike" for their city.

The five teams worked over six months to design, craft and fabricate prototypes, which will be judged by an online vote.

Other recent developments in bicycle design include a model that would quickly dismantle into parts to fit into a backpack and a smart bike that gives riders directions as well as providing alerts.

    The ugliest neat solution you’ll ever see. A shame because it’s a nice concept. The symmetrical frame feels incredibly wrong, and those huge bulbous connectors are just far too much.

    The lights become blocked and useless when the “clip-on accessories” are in use. A bit silly.

      Actually, you’re wrong. Take a better look.

    Uhh…’permanently bolted on’ to bikes’? Hardly. I chop and change parts and accessories on and off my bikes all the time and do most of it needing nothing more than a cheap allen key multi-tool.

    Many accessories such as panniers and child seats also have quick release latches – okay, so the rack or mounting is still on the bike but that’s hardly much of an issue, is it?

    What’s more, bolts and screw threads are international standards. My bike frame is over 12 years old, but I can still bolt pretty much anything to it, and I can choose from a wide range of brands and products.

    Like most proprietary systems, this concept is limited by what the designers produce and if any third parties adopt the system.

    Personally, I think it’s a solution in search of a problem. However, there are some very nice details and I’m sure it’s a beautifully built bike.

    Good idea and also looks cool. Full stop.

    The pedals look to be further forward, relative to the saddle, than they would typically be. It would be interesting to know whether this affects the comfort.

    The rear wheel could easily be positioned a little further backwards without compromising the area necessary for the connecter. Other than the shape of the frame I think that it looks really elegant.

    Couldn’t see in the article, but if they’re very easy to chop and change via the spring loaded system, would this not lead to quite easy theft? Pessimistic I know, but I’ve had enough lights nicked to always see the bike half empty.
