Evil OfferingvsIbis Ripmo

The Evil Offering V4 sits on a radical 79-degree seat tube angle that makes it look like it's perpetually trying to climb a wall, while the Ibis Ripmo V3 introduces a rare "Extra Medium" size to fix the fit gaps most brands usually ignore. One is a dedicated jib machine that refuses to plow through rocks, and the other is a refined efficiency king with internal storage and size-specific bottom bracket heights.

Ibis Ripmo

Overview

Evil and Ibis have taken two paths to the 150mm travel category. Evil's Offering V4 sticks to its guns with the Delta-link suspension, now finally ditching the polarizing SuperBoost 157 spacing for a standard 148mm rear end to please the wheel-swapping masses. It remains the more opinionated of the two, eschewing the trend of making every bike a miniature enduro sled in favor of something that feels like a big BMX bike. The Offering is intentionally more active under pedaling to prioritize climbing traction, a choice that reflects its boutique, rider-focused roots. Ibis, meanwhile, overhauled the Ripmo V3 to be a modular platform. By swapping a clevis and shock, this frame can transform into a shorter-travel Ripley, a level of versatility the Offering simply doesn't match. While Evil focuses on a specific, poppy ride feel, Ibis added "Stow" internal storage and custom Cotopaxi bags, signaling its intent as a bike for riders who want to spend eight hours in the woods without a backpack. The Ripmo is the more calculated, broad-appeal machine, but it lacks the "soulful" mechanical quirkiness that Offering fans crave.

Ride and handling

Descending on the Offering feels like playing on a trampoline. There is a specific point in its 151mm travel where the bike wants to throw you into the air, making it arguably the easiest bike in its class to jump. It is not a plow; if you try to monster-truck through a root garden at high speed, the rear end can feel harsh and less composed than a dedicated racer. You have to ride it offensively. If you get tired and start riding defensively, the Offering stops helping and starts feeling twitchy in the chunder. The Ripmo V3 handles with a more neutral, intuitive balance that makes it feel like it's doing most of the work for you on the climbs. It earns the "hoverbike" label for its ability to mute square-edged hits while you're grinding uphill, though some reviewers noted the rear end can feel bouncy if you don't spend time perfecting the shock's rebound. On the way down, it maintains more mid-stroke support than the previous generation, yet it hasn't completely lost that "busy" sensation in deep chatter. While it is more stable than the Offering at high speeds, the Ripmo isn't quite the "terrain flattening monster" found in the Ibis HD6. Evil's stiff rear end allows riders to drive hard into corners and compressions, converting trail features into speed. In contrast, the Ripmo V3 has been characterized by some as torsionally softer than the outgoing V2S, giving it a more compliant but less rigid feel when pushing hard into high-load turns. This makes the Ibis easier to ride for longer periods without fatigue, while the Evil demands full commitment and a high heart rate to unlock its potential.

Specifications

Evil has standardized on a heavy-hitting RockShox and SRAM Maven build kit. Using Maven Silver brakes with a 200mm front rotor means the Offering has significantly more stopping power than the stock Ibis builds, which often ship with anemic 180mm rear rotors. This is a real weakness for the Ripmo; a 150mm bike being pushed on long descents needs 200mm rotors at both ends to avoid heat fade and lever pump. For a bike that Ibis claims is EWS-capable, the 180mm rear rotor is a frustrating concession to weight. Ibis provides more drivetrain diversity, offering everything from Shimano Deore to SRAM X0 Transmission. Their in-house Blackbird Send alloy wheels are a standout for durability, featuring internal hollow sections in the bead walls to prevent pinch flats without the harshness of carbon. Evil’s choice to spec BikeYoke Revive droppers across the line is a premium touch, matching Ibis’s move to the 34.9mm seatpost standard. While Ibis includes custom Cotopaxi bags for their internal storage, Evil sticks to a more traditional frame design, though they did add a small fender to keep rocks out of the linkage—a much-needed reliability update.

Geometry and fit comparison

Sizing is where these two really diverge. A Large Offering V4 actually has a shorter reach (481mm) than many modern "medium-large" frames, keeping it compact and easy to whip around. Ibis has gone the opposite way, with their Large reaching out to a massive 506mm and even their Extra Medium (XM) sitting at 478mm. If you usually ride a Large, you will find the Ibis feels like a limousine compared to the Evil, which might feel a bit like a monkey bike for taller riders. The Offering’s 79-degree seat tube angle is one of the steepest in the industry, which is a dream for technical, seated climbing but can feel slightly cramped on flat terrain. Ibis uses a more moderate 76.5 to 77.5-degree angle that scales with frame size to keep the weight distribution consistent. Most interestingly, Ibis raises the bottom bracket as the frames get larger to maintain clearance on the longer wheelbases. Evil keeps a low 351mm BB height across the board, which keeps the center of gravity low but demands more precision to avoid pedal strikes in the technical stuff.

Who each one is for

Evil Offering

The ideal Offering rider spends more time sessioning a jump line or looking for "bonus features" on the side of the trail than chasing a Strava segment. It is for the person who wants a bike that rewards an aggressive, active riding style and doesn't mind a little extra suspension movement on the climbs if it means maximum traction in the roots. If you treat the entire trail as a playground and prefer pop over plowing, the Evil is the clear winner.

Ibis Ripmo

The Ripmo is for the pragmatist who wants a high-quality all-rounder that disappears underneath them. It fits the rider who needs one bike to be efficient enough for a 3,000-foot fire road climb but capable enough to handle a trip to a bike park. It is the better choice for the rider who values integrated frame storage and a lifetime warranty on bushings over a specific suspension personality.
