Ibis’s Mojo HD has long been a mainstay for aggressive trail riding and enduro racing. And of course, as that race format has evolved, so have the bikes. Ibis’s fourth generation, announced today as the Mojo HD4, is its most evolved platform yet for aggressive trail riding and racing. The mix of updated features brings the bike to the edge of what modern, long-travel full suspension is all about.
The HD4 gets a lot of new tweaks. In fact, it’s easier to list what’s NOT changing: chainstay length remains at a constant 43cm, and the bottom bracket height shifts just 1mm.

Chief among the bike’s changes: new geometry, clearly in line with the industry-wide trend toward slacker head tube angles and a longer reach and cockpit. Big updates come in the head angle, which rakes out to 64.9 degrees from the previous HD3’s 66.6, resulting in more trail and a slightly slower steering response; wheelbase grows 28-62mm, depending on the size, and reach grows 4-34mm, again depending on frame size. Ibis actually reduces the standover height across the range, and the seat tube is now bored out to accept longer dropper posts (up to 170mm on most sizes; the small fits up to a 150mm dropper).
The DW-Link suspension gets stiffer upper and lower links and a more progressive shock curve to better handle the big hits from aggressive riding styles. The redesigned links are accompanied by a new carbon fiber frame layup that Ibis says is stiffer as well. With Boost spacing front and rear, the new HD4 will clear 27.5 tires up to 2.8 inches wide. The HD4 does not have adjustable geometry, though, and isn’t marketed as compatible with 29-inch wheels.

Pricing stays the same as the older Mojo HD3: $3,000 for the frame and Fox Float shock, with complete bikes starting at $4,200 with SRAM’s NX 1x groupset and Ibis 736 aluminum wheels with a Fox Float 36 fork; Ibis’s online build configurator offers upgrade options for wheels, suspension, and other components. More shock and component options will be announced shortly. The HD4 will start shipping June 15.
