Bionicon has been evolving its unique adjustable geometry bikes for years â and the latest Edison finally delivers on the firm's promises.
While the Edison EVO's linked suspension is the big news, the Edison frame is a decent mountain-ready chassis with an ISCG-05 chain guide mount and neat 142x12mm axle system. Cables are routed externally, except for the dropper post. It comes in 180mm (7.1in) and 160mm (6.3in) travel versions, with a choice of 650b or 26in wheels and two spec levels, plus a raw finish option too.

Bioniconâs geometry change system means a lot of cables, even with a 1x11 transmission
The SRAM X01 transmission is ideal for trail and enduro work and production bikes will get SRAM Guide RSC brakes instead of the Avid Trails of our sample. The semi-polished DT Swiss Spline Two wheels are light and tight, and the Maxxis grip-and-slip rubber combo is spot on, while the Answer cockpit is on point and the KS seatpost is a reliable favourite.
While you can buy the Edison with a conventional RockShox Pike RC fork and Monarch Plus shock, itâs Bioniconâs geometry change system that grabs innovation awards. This uses a custom Magura shock with a large air reservoir, linked to both a handlebar remote switch and a modified X-Fusion Metric fork. Pressing the switch and shifting your body weight lets you adjust the fork travel and geometry from the full 180mm stroke with a 65-degree head angle to a 100mm (3.9in) stroke and steeper head angle for techy climbs. As you reduce fork travel the system incrementally extends the shock to keep the BB height stable, and the altered linkage angle creates a mechanical platform effect.
