XEF 1.8 Sport

This MTB speed measure favors setups that roll efficiently without sacrificing too much traction. In day-to-day use, it's tuned for reliability and control rather than maximum speed. The biggest contributors are wide, grippy tires that trade speed for traction, wheel momentum that helps it carry speed between pedal strokes, mid-size wheels that balance agility and momentum, and a more budget-friendly drivetrain...

On steep roads, it comes in at 6.3/10. Within e-mountain bikes, it lands around the middle. It’s set up for steady spinning on climbs. The easiest gear works out to about 18.7 gear inches. In its peer group, it lands around the easier ~44% for low-gear climbing. We use “gear inches” as a shortcut for climbing gearing. Lower numbers mean you can spin more easily when it gets steep. The motor support helps you keep rolling when the slope kicks up. You’ll be able to keep a steady spin even when it gets steep. Build kits can differ by size and spec level, and not every detail is published by every brand, so use this as a practical guideline.

Suspension performance: 9/10. It’s grouped into “Extreme rough-terrain ready”. It’s designed for aggressive rough-terrain use where hits are large and frequent. Full suspension helps the bike stay calmer under braking and cornering on rough sections. This level is meant for the most demanding roughness, staying stable through repeated big impacts.

Balanced fit - a versatile position for long rides and faster efforts. Based on full geometry data.

Fit adjustability is shaped by a few key choices: This front-end is not locked into a one-piece system, which helps adjustability; The front-end is easier to work on, supporting fit tweaks over time. That is why we tag it Moderately Adjustable.

Ride comfort is 8.9/10 — on a real ride it feels very smooth. That’s the reason it lands as Comfortable. It’s running about 127 mm tires on 27.5" wheels, and the high-volume tires add a lot of damping and grip on roots, rocks, braking bumps, and repeated hits. The posture is neutral (posture 6/10), which keeps it balanced — not overly aggressive, not overly relaxed.

This bike is made for very rough terrain, big hits, and bike-park riding. It has about 180 mm of suspension travel (how much it absorbs bumps), which is useful for big hits and steeper descents. Suspension type (Full) fits this kind of terrain.
