Ibis Mojo 4 Review — A Serious Full-Suspension Trail Ripper

2022 ibis mojo 4

Did you know that it took around 2,000 CAD hours to develop the original Ibis Mojo, and the Mojo 1 was the first carbon full-suspension mountain bike ever made?

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.

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 full-suspension 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.

Light, live and nimble

Ibis recently released its fourth iteration of the full carbon, dual suspension Mojo in June 2020. 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!

    A lightweight yet durable chassis with EVOL air spring on GRIP 2 dampers – great for going up & down the mountain

    Air spring, dual-piston damper with 3-position switch which conserves energy when you need it the most
  • 12-speed drivetrain
  • A carbon frame with a DW link suspension
  • TLR wheels
  • Tires – Schwalbe Hans Dampf (front), Nobby Nic (rear)
  • 27’5″ wheels
  • 2.6″ wide tires
  • Dropper seat post
  • Color options: Dirty White Board / Blue Dream

Ibis Mojo 4 Deore – 2021

MSRP $4,490

The Deore build 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 S35 aluminum TLR rims
  • Drivetrain – 1×12 Shimano Deore M6100
  • Shimano Deore 6100 Shadow Plus rear derailleur
  • Shimano SB-BB52 bottom bracket
  •  
  • Deore M6100 10-51T cassette
  • Removable ISCG mount
  • Polycarbonate downtube protection
  • Seat tube angle: 76.7° – Head tube angle: 65.4°

Ibis Mojo 4 SLX M7100

MSRP $5,399

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. 

  • 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.


Ibis Mojo 4 GX Eagle

MSRP $5,699

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 than 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. 

  • Forks: 140mm travel Fox Float 34 – Factory Series GRIP2
  • Rear shock – 210 x 50mm Fox Float Factory Series, DPS w/ EVOL
  • 12-speed SRAM GX Eagle
  • Internal cable routing
  • DW-link suspension platform
  • Rims – Ibis S35 aluminum on Ibis hubs
  • BikeYoke Revive dropper seat post
  • WTB Silverado 142mm saddle
  • SRAM XG 1275 – 10-50T cassette
  • SRAM DUB BSA bottom bracket
  • SRAM GX Eagle 175mm – 32T crankset
  • Cane Creek 40 ZS44/ZS56

One notable upgrade is the Ibis Hi-Fi carbon handlebars, which shave considerable weight off the bike and feel lighter to handle. 


Ibis Mojo 4 XT M8100

MSRP $6,099

The XT build is the top of the range for Shimano fans, with a lovely 1×12 Shimano XT groupset and XT 2-piston 180mm brakes. This is where the Ibis Mojo 4 gets moves into the realm of seriously high quality, breaking just above the $6,000 mark.

  • Forks: 140mm travel Fox Float 34 – Factory Series GRIP2
  • Rear Shock – 210 x 50mm Fox Float Factory Series, DPS w/ EVOL
  • Internal cable routing
  • DW-link suspension platform
  • Rims – Ibis S35 aluminum on Ibis hubs
  • BikeYoke Revive dropper seat post
  • WTB Silverado 142mm saddle
  • Shimano XT – 10-51T cassette
  • Shimano XT MT800 Bottom bracket
  • Shimano XT M8100 175mm – 32T crankset
  • Shimano XT M8100 Shadow Plus rear derailleur
  • Cane Creek 40 ZS44/ZS56
  • Industry Nine A318 stem
  • Lizard Skins – Charger Evo grips

On top of the impressive groupset upgrade, you also get a lightweight Industry Nine stem and the Hi-Fi carbon handlebars. The dropper seat post, suspension, and wheels remain unchanged.


Ibis Mojo 4 XX1 AXS

MSRP $10,699

The XX1 AXS is the absolute cream of the crop build of the Mojo 4, blasting itself way ahead of the competition (and out of the average person’s budget). With almost every component upgraded to the best available, this is a professional, competitive bike for serious contenders. 

FOX
140mm travel Fox Float 34 Factory Series GRIP 2 fork
210 x 50mm Fox Float Factory Series DPS w EVOL rear shock

SRAM
Eagle XX1 AXS trigger shifters
Eagle XX1 175mm, 32T crankset

XTR M9100 2-piston hydraulic disc brakes

ENVE
M6 Bar 780mm handlebar
ENVE MTN 31.8mm stem

IBIS

With an Enve stem and handlebar, wireless seat post, and Ibis Carbon wheels you can’t help but feel you are riding an exceptionally well-engineered piece of machinery. As with all previous builds, the XX1 maintains the FOX front and rear suspension and Schwalbe Hans Dampf 2.6” tires.

Ibis Mojo 4 CONS

  • You might want to invest in proper chainstay protection on the frame to prevent paint damage.

Conclusion

  1. B. says:

    If I purchased this Mojo 4 but wanted to add more travel to the front end on top of the 140mm, is it possible? if so, what part do you upgrade and rough price range?

    Thank you

    1. Sam Millers says:

      Hi B

      Swapping out the 140mm to 150mm is the most common upgrade many Mojo owners have been dealing with.
      Although we are talking of 10mm (3/8″) of change which is not a lot, but surely, it seems like a solution to get a smoother ride on faster sections.

      There are some things to consider though:

      1. Ibis Mojo 4 is truly one of the best bikes in its category (Price/Quality/Travel/Geometry), and it is obviously the most upgraded model from the series you can get. Which means – it is the final, 4th version of the Mojo series. I wouldn’t personally change anything about the bike, besides the compression/rebound on the fork.

      2. When swapping out the fork is your first consideration, make sure to check the warranty if that backs up the change.

      3. Rest of the bikes by Ibis:
      Mojo HD5 – 170/153mm
      Ripmo – 160/147mm
      Ripley – 130/120mm

      If that 150mm is your definite go-to factor, you want to look in for a new air chamber/air shaft assembly that is fairly cheap and easy to fit. We’d recommend asking for more information from your local bike store that deals with MTB service.
