Ibis Mojo 4 – 27.5 Ain’t Dead! The Ibis Mojo Gets Major Update

This colour Mojo 4 is ‘Dirty Whiteboard’ apparently

After the new 29in Ibis Ripmo appeared in 2018, followed by the revamp of the Ibis Ripley last year, it perhaps is no surprise that the venerable Ibis Mojo gets pulled into the new decade with the launch of the Ibis Mojo 4. In line with just about everything these days, it has a slacker head tube, longer reach, a steeper seat angle, accommodates longer droppers and gains suspension tweaks pioneered on the Ripmo. But the new Mojo 4 retains the 27.5 wheels of the previous version and it continues as the flagship Ibis trail bike, even if the pesky 29ers have been stealing the limelight recently.

What’s in a Mojo?

The Mojo name is an important one for Ibis, having first appeared on a (steel) Ibis frame back in 1994 and it was the name that helped re-launch the company in 2005 when it introduced its first, full carbon monocoque bike – the (26in wheeled) Ibis Mojo. Since then, the Mojo has gained 27.5in wheels and remained in the line, even while other models were getting radder (like the MojoHD) or going all 29in enduro (like the RipMo)

What’s new?

So, what’s new with the Ibis Mojo 4? Well, a lot of what was new with the recent Ripley v4 really. The geometry has been tweaked to bring it up to date – so it now has a slack 65.4° head angle with a steep 76.7° seat angle. The reach has been increased across the board, so a Medium gets a 460mm reach and a Large, 485mm.

Smaller and nippier wheels on a playful bike make for fun times.

The wheel size remains at 27.5in and the travel is 130mm of DW-Link travel out back, with a 140mm fork specced up front. There are four sized, from Small to XL, fitting riders from 5ft to 6ft 6in. In keeping with modern demands, a full size bottle will fit in all frames while the standover has been reduced so that longer (170mm+) dropper posts will fit size Medium and above (125-150mm on the Small).

Goes sideways well. Goes in a straight line even better!

It’s been four years since the launch of the Ibis Mojo 3 and much has changed. For a start, the 27.5 x 2.8in tyres that the Mojo 3 accommodated have fallen out of favour on trail bikes, so the new Mojo 4 ‘only’ takes a 2.6in tyre. Other changes on the Mojo 4 over its predecessor is the newer style, metric shock and a change to the suspension links – the lower one now gets an IGUS bushing, as it only moves a few degrees and this is better suited to a bushing, reckons Ibis. The upper link retains bearings and this has worked well since the RipMo came out. There’s a lifetime warranty on the bushings if you’re that concerned, as well as a seven year warranty on the frame.

You wanna see my IGUS bushing? Well, that’s where it is. Threaded bottom bracket shell too.

What else? The frame weighs 5.9lbs with a Fox DPS shock, with complete builds starting at 26.7lbs. There’ll be two different colours available: Dirty Whiteboard and Blue Dream and a range of builds, from Deore up to SRAM AXS XX1

And now, it must be time for a feel-good family-friendly film!
