2021 Ibis Mojo 4 Review

Ibis is an adventure cycling brand from California that started life in 1981 and now sells a wide variety of XC, gravel & CX, mountain, and trail bikes aimed at the high-end market ($3,000 – $10,000+). It stocks five dual-suspension MTBs in both 29” and 27.5”, a 29” hardtail, and a 700C solid fork bike. The Mojo – self-described as an “All-mountain play bike” – is the brand’s flagship product.

The Mojo series first saw the light in 1994! Back then, the first Ibis Mojo was equipped with Mavic 230 rims, Specialized Auto-Pilot grips, and loaded with XTR components. You had the choice to choose the forks between Manitou 3 or Rock Shox Mag 21/Mag 21 SL Ti.

BEST FOR Trail, All-mountain

It’s no surprise that the modern Mojo has seen a ton of moderation in every department, and their newest 2021 model carries a strong tradition into the trail-mountain biking industry.

Full-Carbon Mojo Origins
Comments from a 2015 interview by Scot Nichol, the owner of Ibis Cycles, when the first carbon FS Mojo was released.

  1. We wanted to build a dual-suspension carbon fiber mountain bike 
  2. We wanted to do a long-travel bike that pedaled very well when the long travel was all about the gravity
  3. By knowing that carbon fiber could be built into these gorgeous organic shapes.,” we decided let’s not have an engineering design our bikes. Let’s have designer design our bikes and then engineers verify these shapes

The carbon Ibis Mojo is designed by Roxy Lo

The new IBIS MOJO 4 2021 review

Ibis recently released its fourth iteration of the full carbon, dual suspension Mojo. The new model has 27.5” wheels with 140mm travel up front and 130mm on the rear, making it ideal for both park tricks or aggressive downhill riding. Ibis has added Traction Tune to maintain smooth yet aggressive riding performance over long distances. The geometry is also known by having superb climbing capabilities!

Light, live and nimble

The Whole 2021 Ibis Mojo 4 series is based on:

Ibis Mojo 4 Deore – 2021

ibis mojo 4 deore 2021 full suspension bikeThe Deore built kit for the Mojo features a 12-speed Shimano Deore drivetrain and 2-piston 180mm disc brakes. It’s the entry-level Mojo so has some slightly lower quality components like an aluminum handlebar, which adds a bit of weight. However, with the incredible Mojo frame and FOX dual-suspension, this is still a killer bike.

Ibis Mojo 4 SLX M7100 – 2021

27’5″ x 2.6″ / Shimano SLX M7100 Groupset / Carbon frame / 12-speed / 2-piston hydraulic disc brakes / Fox Float rear shock & forks

ibis mojo 4 slx 2021

The Mojo 4 SLX build features a 12-speed Shimano SLX drivetrain with SLX 2-piston 180mm disc brakes. It features the slightly improved BikeYoke Revive dropper seat post with an additional 35mm of vertical movement, which really offers a lot of room to move. 

MSRP $5,399
>> JensonUSA

  • Front Fork – 140mm travel Fox Float 34 Factory Series GRIP 2
  • Rear Shock – Fox Float Factory Series, DPS with EVOL, 210 x 50mm
  • Wheels – Ibis S35 Aluminum, Ibis hubs TLR
  • Tires – TLR Schwalbe Hans Dampf (f) / Nobby Nic (r)
  • Rear derailleur – Shimano SLX M7100 Shadow Plus
  • Headset – Cane Creek 40 ZS44/ZS56
  • Dropper Seatpost – BikeYoke Revive
  • 10-51T Shimano SLX M7100 cassette
  • Shimano SLX BB52 bottom bracket

The rest of the build on the SLX is comparatively similar to both the Deore and the next build-up, the SRAM GX Eagle. It SLX groupset definitely gives the bike a smooth, tighter feeling but it is still lacking in some of the finer finishing that the higher builds offer.

For SRAM fans, the GX build of the Ibis Mojo 4 is the most affordable of the SRAM builds, coming in just under $6,000 and only slightly more expensive the SLX. Other than the very attractive addition of the 12-speed SRAM GX Eagle groupset, it is kitted out almost identical to the previous two models with the same suspension, wheels, and tires.

Ibis Mojo 4 2021 Torque Specs (At the very bottom – right tab)




The Ibis Mojo 4 is the ideal all-rounder bike as it handles serious downhill charges, fast trail riding, and park tricks all equally well. It’s best suited to riders who enjoy a bit of everything and find they don’t have space (or the budget) for any more bikes. With the Mojo 4, you may never need to buy another bike – just hop on, start riding, and feel as it adjusts itself to your current mood. It’s like the Swiss army knife of mountain bikes!

Ibis Mojo 4 CONS

  • Some owners of Mojo 4 claim that the lower link on the rear shock doesn’t have too much cover from the rocks and mud which might eventually damage the paint in the long run.
  • You might want to invest in proper chainstay protection on the frame to prevent paint damage.
