Ibis has significantly enhanced the numbers on its proven Mojo trail bike range.
An iconic design, the Mojo popularised organic carbon-fibre frame shaping and cross-bracing technology on debut, back in 2005. Since then, it has steadily been evolving as mountain biking transitioned to new wheel sizes and geometry trends.
With its Mojo 4, industrial designers at Ibis have meaningfully progressed the bike’s geometry, without sacrificing agility.
Unlike like most contemporary trail bikes, the Mojo 4 rolls 27.5 inch wheels and they support a redesigned carbon-fibre frame with 130mm of rear suspension travel. Ibis invested in new moulds for the Mojo 4, allowing its designers to execute considerable geometry changes.
This new Mojo has a 65.4-degree head angle, which is notably slacker than its predecessor’s 67.1-degrees. Ibis Mojos have traditionally been short bikes with intuitive steering responses, especially in tight singletrack terrain, but the Mojo 4’s reach has stretched by a touch more than 40mm per size.
Ibis wished to give the frame greater high-speed tracking stability and the size large Mojo 4 now measures to 485mm reach, a significant increase over the Mojo 3’s 441mm.
The stays have also been narrowed, reducing tyre clearance from 2.8- to 2.6in and delivering a frame which weighs 2.67kg. Standover on the Mojo 4 is lower too, giving riders the option to run larger dropper seatposts. Mojo 4s size medium and up, will accommodate droppers longer than 170mm.
Supporting the Mojo 4’s DW-linkage is a 210 x 55mm metric shock, managing 130mm of rear travel, balanced by a 140mm fork. The Mojo 4’s suspension differs from the 3, by using a 37mm offset fork up front and replacing the lower link bearings at the rear with IGUS bushings, which carry a lifetime guarantee.
Ibis is offering its new Mojo 4 in a range of builds, starting at $4,499 and peaking at $10,699.
