Bionicon Edison Evo – Two bikes in one?

by

Taking a very particular approach to solve some of the issues that arise out of alpine riding, Bionicon have released the Edison Evo a further refinement of their variable travel and geometry approach to bike design.

140mm?

The idea behind the engineering is that a bike should be able to climb well and descend with equal efficiency. If you think about typical non lift assist alpine riding, where two hour plus fire road climbs are possible before you point your bike downhill for a nice long descent it’s easy to come to terms with what Bionicon are aiming to achieve: A bike where climb mode equates to a steeper head angle and shorter travel (like a mountain goat) and descend mode slackens the front off and increases travel. Simples hey?

Or 170mm, you’ve got the choice

All this is achieved via a neat little thumb switch that sits on the handlebar and allows adjustment of the customised Magura built shock and X Fusion Metric fork up front. The Edison Evo sees a move into single crown forks where previous models used a triple clamp.

The great thing about the system is that it isn’t binary, but offers infinite adjustment between it’s 64° headangle/180mm mode and 69°/140mm at the other end of it’s travel spectrum.

With a bit of practice, subtle body movement and weight shifts on the bike it’s possible to fine tune the stance on the bike on the fly. With the opportunity to ride the bike around the not so alpine environment of Cannock Chase, our Richard was soon pedalling and adjusting as he rode along, depending on what the trail ahead was offering up in the way of challenge.

With a 1 x11 X01 drivetrain, KS Lev dropper, DT Swiss Spline wheelset and SRAM Guide brakes the Edison Evo is available for what seems like a very reasonable €3600. According to Roger from Bionicon it weighs in at ‘around 33lb’. A 160mm model is also offered.
