The new Ibis Mojo 4 frame is here. The word Mojo refers to a magic spell or charm, and more broadly - a magical power. Since its introduction in 1994, the Mojo has delivered a wicked combination of fun and all-mountain prowess. The newest version is a super-fun 27.5" wheeled ripper.

Purchasing as a frame only makes a lot of sense, not least because Ibis UK famously hold so little stock of the set build kits. If you need any help or a quote for your dream build drop us an email at or call us on 01227 832582 and we'll help get it together for you.

Ibis Mojo 4 Frame Features

Geometry: The Mojo V4 fea­tures a 76.6-degree, get-you-up-that-hill seat tube angle, our short­est chain­stays, and a spa­cious reach with a 65.4-degree head­tube angle. This enchant­i­ng com­bi­na­tion rolls on 27.5” wheels, to deliv­er that hov­er­bike feel with on-trail confidence.

DW-Link Suspension - Since 2005, we’ve part­nered with sus­pen­sion guru Dave Wea­gle on the dw-link sus­pen­sion plat­form. It pro­vides an unpar­al­leled com­bi­na­tion of climb­ing effi­cien­cy and down­hill per­for­mance, which has been proven repeat­ed­ly at the high­est lev­els of racing.

Traction Tune - Our cus­­tom-tuned sus­pen­sion fea­tures extra light high-speed com­pres­sion and rebound damp­ing to deliv­er unpar­al­leled trac­tion. When paired with our dw-link sus­pen­sion plat­form, Trac­tion Tune allows the Mojo to track like a big bike with­out com­pro­mis­ing crisp ped­al­ing per­for­mance. To learn more about our Trac­tion Tune phi­los­o­phy, click here.

Short Fork Offset - Reduced-off­set forks give the front wheel greater sta­bil­i­ty at speed and an addi­tion­al sense of steadi­ness at slow speeds too. The Mojo is designed to excel in tech­ni­cal, demand­ing ter­rain, and the 37mm-off­set gives that extra bit of con­fi­dence and con­trol in the most chal­leng­ing situations.

Tyres - The Mojo has clear­ance for 27.5”x2.6” tires. You can run over­built, chunky tires; you can run light, big vol­ume fast tires, but what­ev­er you run, know that you’re not lim­it­ed by width.

Bushings - Tired of hit­ting “pur­chase” on anoth­er set of bear­ings each sea­son? So were we. That’s why we use bush­ings where they make sense, and bear­ings where they don’t. The IGUS bush­ings in our low­er link are lighter and stiffer than bear­ings, and vir­tu­al­ly main­te­nance free. We believe so strong­ly in them, we back them with a free life­time replacement.

Carbon - All our bikes are built from the high­est grade mate­ri­als and opti­mized for the best strength, weight, stiff­ness, and ride per­for­mance — no mat­ter how much you spend. The Mojo weighs a svelte 5.9 lbs with an inline shock and com­plete builds start at 26.7 lbs.

Internal Cable Routing - Bikes that look pret­ty on the out­side, should look pret­ty on the inside. We use car­bon fiber tubes mold­ed with­in each frame. Push the cable in, watch it pop out, a beau­ti­ful moment indeed.

Frame Protection - A poly­car­bon­ate down­tube pro­tec­tor deflects debris, while mold­ed rub­ber swing arm pro­tec­tors keep things qui­et and clean. Sim­ple-yet-ele­gant link­age pro­tec­tors stop mud and rocks thrown by the tire, keep­ing your beau­ti­ful bike beautiful.
