XEF 1.8 Sport

For mountain riding, it captures how the bike carries speed when you're pushing the pedals on less technical surfaces. The score is largely shaped by wide, grippy tires that trade speed for traction and a more budget-friendly drivetrain that focuses on value. All combined, they influence momentum - how hard it is to get moving and how hard it is to keep moving.

Climb score: 6.6/10. Within e-mountain bikes, it lands above average. It’s set up for steady spinning on climbs. The easiest gear works out to about 18.4 gear inches. Compared with similar bikes, this low gear is easier than about ~49% of them. Gear inches is basically “how easy is the easiest gear”. Lower numbers help you keep your legs spinning on steep bits. E-assist can take the sting out of steep ramps, especially at lower speeds. Good for keeping cadence steady on climbs without overcooking it. 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.

For suspension control, it lands at 9/10. Category: “Extreme rough-terrain ready”. This level targets big hits and very rough trails, prioritizing stability under repeated impacts. Both ends absorb impacts, improving how consistently the tires can follow rough terrain. It’s tuned for steep, rough terrain where keeping the wheels tracking under hard hits is the priority.

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

In E-bikeMountain, Overall, it is Moderately Adjustable. Why this fit flexibility rating: Standard cockpit parts make it simpler to fine-tune your position over time; Less routing complexity makes swaps and adjustments more practical. In practice, it is about how easy fit changes are with normal parts and service work.

Comfort comes out to 8.9/10, which usually translates to a plush ride. That’s why it’s labeled Ultra Smooth. 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 setup is designed to stay stable and grippy on softer surfaces. Tires around 5.0 in usually mean it’s more confident on loose, soft surfaces (for example sand or snow). Even though it’s tagged Enduro, the setup fits Soft Terrain better.
