| Fork | FOX 38 Performance GRIP, 170mm 29 |
|---|---|
| Shock | FOX X2 Performance Elite, 205x60mm |
GX AXS Transmission Suspension Details
The Ibis Oso GX Transmission build features a FOX Performance Float 38 fork with a GRIP damper.
The rear shock is a FOX Performance Elite X2. The Performance Elite utilizes the same damper as the FOX Factory X2 but with the black ano shock shaft.
A very popular upgrade to the Oso GX Transmission is to swap the GRIP damper for a GRIP2 damper. This creates essentially a Performance Elite fork. Like the rear shock a Performance Elite fork provides high and low speed compression as well as rebound settings. These four adjustments as well as volume spacing produce the widest setup range available.
You can read more about the advantages and setup of the Factory and Performance Elite 38 and X2 by following the links below:

GX AXS Transmission Wheel and Tire Details
Ibis spec’s the Blackbird Send with Ibis hubs for the Oso GX Transmission build. These are great wheels for riders looking at higher volume options.
Some eMTB riders will upgrade the wheels to more robust hub systems such as Chris King, Industry Nine or Onyx. If you’re shopping hubs it’s a good time to consider whether you’ll prefer aluminum rims like the WTB, RideFast or Factor or whether the improved power transfer and tracking of carbon like NOX or Ibis Carbon suit your riding.
BikeCo offers a selection of the best components built by our in-house experts. This allows us to fine tune your wheelset to compliment your riding style nad needs.
With the addition of the Bosch motor the eMTB Oso specs tires known for great performance in burly terrain. Both front and rear tire are spec’d with 3C MaxxGrip rubber and Double Down sidewall technology.
Some riders will prefer a rear tire with a bit more bite than the Aggressor to compliment the Assegai front tire.
Have a favorite tire combo? Let’s get you dialed in. Tires are a very personal feel and if you prefer an EXO Plus rear, or a Double Down front, or a DHF, Dissector, Aggressor, whatever – let’s get you setup right, right out of the box.

The Oso features great eMTB brakes: the Shimano XT M8120 4-piston and 220mm rotors. However, many riders may prefer a different feel – particularly on an eMTB that’s heavier and will require some additional braking compared to a standard bike.
Popular Brake Swaps & Upgrades to the Ibis Oso GX
We offer the best brakes from Shimano, TRP, Hope and Magura.
Getting brakes that compliment your riding style is important for your bike’s performance.
Riders looking for great power with snappy performance gravitate to Shimano SLX, XT and XTR brakes.
TRP offers even a little more power with slightly improved modulation compared to Shimano.
With the Tech 4 Hope has increased their total power in-line with Shimano and Magura without compromising their amazing modulation.
Magura continues to be the most popular aftermarket brake, especially installed on new builds. We will credit you for any part swaps and with the variety of Magura price points most riders find the MT5 and MT7 brakes provide unbeatable value. Magura brakes offer great total power and top tier modulation without feeling soft. Magura offers a variety of brake levers to help riders fine tune their performance.

Ibis Oso Geometry

Ibis Oso Geo
For Oso geometry details or to compare the Oso with other class leading Enduro e-bikes use these tabs.
The Ibis Oso GX Transmission Build is available in sizes Small, Medium, Large and X-Large. As the Small and Medium are Mullet bikes, 29 front and 27.5 rear wheels while the Large and X-Large are 29 front and rear riders between Medium and Large have personality differences as well as sizing variations.
With a 64 degree headtube angle across all sizes the steering performance and trail measurements are well behaved regardless of size. The effective seat tube angle varies across the sizes as the saddle moves further from the bottom bracket. This gives the Oso a well balanced position for technical climbing.
Standover between the Large and X-Large is similar however the seattube length and top tube have expected differences.
Like most enduro bikes the Oso fit is going to be based around riders height, inseam, shoulder width and arm width.
Inseam and leg length make a large difference in sizing options. Longer legs typically will upsize while riders with longer torsos will review saddle height, stack and reach to determine which size will fit their riding styles.

Ibis Oso with X0 Transmission AXS Custom Build
Check out some pictures of this banger custom eMTB. Ibis Oso with X0 Transmission AXS drivetrain, Magura brakes, Handbuilt King/Nox wheels and more. Built by the team here at BikeCo.com.
Magura MT7 with HC3 levers paired to 223mm Galfer Shark rotors provide the stopping power.
The HC3 lever is adjustable which allows for riders to fine tune the leverage ratio. This adjustment shifts the length between the lever pivot, the lever “action” arm and your finger tip. Want the power to come on a little quicker? Drive the adjustment further towards your finger tip. Looking for more modulation? Reverse the adjustment.
The HC3 is the most adjustable lever on the market. It allows riders to utilize the larger diameter rotors, great for eMTB setups like this Oso, without being jumpy.
Ibis Oso with X0 Transmission
Yes, this Ibis Oso with XO Transmission takes advantage of wireless shifting. But there’s many more advantages to the X0 Bosch Transmission AXS Groupset on an eMTB setup.
Between the additional weight as well as the mileage and technical climbing eMTB drivetrains are under more stress than we’ve seen before. This tends to lead to wear issues and replacement at a more frequent basis than riders might be used to on their MTB setups.
With the SRAM X0 Transmission riders are purchasing the strongest and longest lasting drivetrain built. Period. The most notable changes on the SRAM Transmission include the unique Flattop chain (which, just plain looks cool) as well as updates to the rear derailleur.
The Transmission derailleur is a robust piece utilizing a double shear mounting on the SRAM UDH capable rear end. With a precision initial installation the Transmission derailleur is ready to go for a long time without requiring much from a rider.
With eMTB riders climbing technical tracks it’s also great that IF you manage to damage the derailleur you can replace individual bits on the derailleur. They’re built to take a hell of a beating, so this may never happen to you…
Questions on which Transmission kit is right for your project? Chat with our team and we’ll get you the right bits to take you trail experience to the next level.
OneUp Components E-Bar: Simplified Controls
A clean cockpit is provided by both the Transmission wireless pod as well as OneUp’s Carbon E-Bar.
The 35mm Carbon E-Bar allows clean control wiring for the motor. Bosch and Shimano systems can take advantage of this.
The ANVL Swage Stem is used to compliment the E-Bar’s wiring.

Another look at the cockpit on this custom Ibis Oso.
Deity Lockjaw Grips, the new Wolf Tooth ReMote Pro and Chris King Headset provide nice touches across the board.
Heavier bikes, like eMTB builds, as well as bikes that tend to be ridden a lot and hard, like eMTB bikes, benefit from top tier headsets like Chris King or the Cane Creek 110 options.
Ground level looking at the Headtube and fork crown.
You can peak at the SQ Labs saddle and get a detail look at the NOX Kitsuma Enduro rim shape.
eMTB Carbon Wheel Option
Another angle with more of the NOX Kitsuma Enduro rim.
With a relatively wide internal width the Kitsuma provides a lot of tire volume to maximize grip. This is important climbing and descending the Oso to take advantage of its traction.
Chris King hubs with DT Swiss spokes and nipples are laced to the carbon Kitsuma rims. Our expert wheel builders have a good understanding of rider requirements prior to build. This allows fine tuning of both product as well as actual build setup. In turn this produces a rim that balances incredible service life with excellent, personally tuned, performance.
Here is the Chris King rear hub with the SRAM Transmission cassette.
We’ve learned an important aspect on SRAM Transmission installation is ensuring the mounting surface is free of any finishing buildup from the frame. Our team checks the UDH area for any anomalies so our clients have the best on trail performance.
One last look at this custom Ibis Oso build.
This rider has spec’d DH tires front and rear. DH sidewalls have a weight penalty, but provide notably improved damping. With the heavier eMTB bikes and especially with aggressive riders this is important.
Riders find extra support from the suspension critical to performance. Finding the additional damping in cockpit (like the OneUp Carbon Handlebar) and tires is critical!

Ibis OSO eMTB: 155mm DW Rear Travel with 170mm Fork
Ibis launched their long awaited entry into the eMTB realm with the Ibis Oso! With 155mm of Dave Weagle rear suspension paired to a 170mm fork and powered by the powerful Bosch Performance CX motor this is a bike that lives up to its marketing of #DownhillBothWays
Enjoy some detail shots and descriptions of some of the stand out design of the new Ibis below.
Ibis Oso
The Oso has a divergent rear triangle design philosophy than you see on the Mondraker Crafty or the Yeti 160E – more like what we’re used to seeing on a motorcycle – however once you look closer you’ll see familiar details.
The Ibis eBike isn’t a single pivot rear end, instead you’ll see the upper and lower linkage that makes it a DW eBike.
DW eMTB
eMTB puts additional stresses on drivetrain and suspension for a variety of reasons. The bikes are heavier for one, they have the capacity for more power, but even more than that as the Ibis marketing mentioned earlier – they tend to make the riding “Downhill Both Ways” allowing riders to attack climbs previously out of the question.
However this requires another consideration to the suspension and drivetrain interaction as riders are now using more power, much deeper into the rear travel. Top tier designers have to factor this into the functionality of the bike. The stresses on the chain, cassette and freehub body have to be managed as well as ensuring eMTB bikes don’t have drivetrain forces that “lock” or resist fluid suspension movement.
Designed for Riders
Ibis designed the Oso around the rider. With a size range capable of stretching from about 5′ to 6’6″ chances are we can get you fit on the Oso.
To improve performance for smaller riders the Ibis eBike features “mixed” (I guess that’s the new, new term for Mullet?) wheels with a 29″ front and a 27.5″ rear.
The larger diameter 29″ front wheel provides the best roll over with a minimized angle of attack over terrain. Smaller riders will appreciate the smaller rear wheel when cornering or jumping the bike as it provides additional room to move behind the saddle.
BOSCH Performance CX
Medium, Large and X-Large Oso eBikes feature the 750wh battery. The Small Oso features a 625wh battery due to size and weight considerations – but – most small riders are lighter so the performance tends to even out when looking at mileage…
We’ve highlighted the BOSCH Performance’s performance (is duplicating words still considered alliteration? I’m not sure…) but we’ve talked about how the BOSCH mode selection provides riders with unrivaled capacity to balance the power output for their riding needs.
The setup on the Oso is no different in that manner.
Dialing in the Details
It sounds simple – but – you know, umm, simple isn’t always a thing anymore: but I love that the Ibis Oso features “integrated” front and rear lights. Now, for night riding, etc you’re still going to want a bit more (at least a headlamp in my opinion) but why not have the ability to increase your visibility and draw on the battery you’re sure to remember to charge!?
Custom Ibis Oso?!
Of course. It’s one of the things that sets BikeCo apart. Well, that, attention to detail, unmatched after sales service to help you fine tune suspension, tires, cockpit, etc, etc but back to the Custom Oso: Yes, we can do it!
Some common upgrades we’ve seen include upgrading to the Factory Kashima 38 or X2 shock. (Another popular update is to drop the GRIP2 damper into the Performance fork producing a Performance Elite fork with high and low speed compression as well as rebound)
Other riders may prefer Hope or Magura brakes. Not a problem.
AXS anyone? Of course. From GX AXS to XX1 we’ve got you setup with #thebestinMTB
