Que Vaut vraiment le Moins Cher des Fatbikes Cyrusher ? - Cyrusher Zenith - Test Complet !

Cyrusher Zenith Review Summary

Main Specifications and Features

• Price: About €1,299.
• Motor: 250 W rated, with roughly 960–1,000 W peak and 95 Nm of torque.
• Battery: 52 V, 15 Ah. The reviewer initially says 20 Ah, then corrects himself to 15 Ah.
• Claimed range: 96 km, described as theoretical rather than verified in the test.
• Weight: About 34 kg, considered relatively light for a fatbike of this size.
• Wheels: 26 × 4-inch fat tires.
• Gearing: Shimano derailleur. The reviewer considers the gearing fairly basic, noting a low pedalling cadence in first gear on steep climbs.
• Brakes: Logan hydraulic brakes with dual-piston calipers and 180 mm discs, praised for strong stopping power.
• Suspension: Adjustable, lockable front suspension. It handles ordinary rough ground adequately, but the front end struggles over larger bumps.
• Fit and equipment: Comfortable seat with a broad adjustment range. The frame is available with or without a crossbar, and the bike comes in three colours.
• Display and controls: Bright, clearly readable screen showing battery, mileage, speed and other ride information; five assistance levels.
• Lighting: Front light and frame-mounted lights that brighten when braking; no light at seat level.
• Sensors: The bike advertises both torque and pedal-assist sensors. The reviewer also notes that a throttle can be added for off-road or closed-road use, subject to local rules.

Riding Experience and Performance

• The bike feels comfortable and stable, with a good riding position and easy-to-reach controls. The testers say its 34 kg weight is not especially noticeable while riding.
• A rider weighing roughly 100 kg climbs steep gravel and grassy slopes successfully, generally at around 8–15 km/h, without needing to push hard. The motor’s assistance is considered a major strength.
• Removing the speed restriction does not appear to improve climbing performance; it mainly raises the top speed.
• In the unrestricted test, the Zenith reached about 32–33 km/h in the reviewers’ runs, with one brief reading around 34 km/h. As delivered, it is configured for the legal 25 km/h limit.
• The torque sensor responds readily: even slight pedal pressure can bring in substantial assistance. The reviewers find that the torque and cadence modes feel surprisingly similar, with little practical reason to switch between them.

Pros

• Strong climbing ability, including under a heavier rider.
• Good value for the price, with a finish and build quality the host considers particularly impressive in its category.
• Powerful brakes, comfortable seat and generally reassuring handling.
• Bright, informative display and useful lighting.
• Relatively low weight for a fatbike.
• Useful seat and suspension adjustability.

Cons and Reservations

• The torque sensor is overly sensitive, delivering near-full assistance with very little effort. This makes it feel much like the pedal-assist mode and undermines the claimed benefit of having two distinct sensor behaviours.
• The front suspension is the clearest ride-quality weakness, especially over large bumps. One tester also finds the front end heavy.
• The gearing is basic for steep climbs.
• The stated 96 km range is theoretical; the video does not establish a real-world range.
• The unrestricted speed discussed in the test is not the bike’s normal legal configuration.

Comparisons and Overall Verdict

The host says the Zenith is essentially the same bike as the previously tested Cyrusher Aura/Shera, with the crossbar and colour options being the main differences. He found the earlier bike’s sensor behaviour similarly confusing.

Compared with dual-sensor systems on some other brands, the Zenith’s two modes are described as much less distinct. The host suggests that a less sensitive torque sensor—or retaining the torque sensor and adding a throttle—would make more sense.

The Dukawey T20 Pro is also ridden and discussed. The comparison highlights differences in suspension and bike character rather than establishing a direct winner.

The reviewers regard the Zenith as a very capable, well-finished fatbike for the money, particularly for climbing and general all-terrain riding. It is a strong value choice if its highly responsive assistance suits the rider, but the front suspension and the lack of a meaningful difference between its two sensor modes are notable compromises. No formal numerical rating is given.

Different Speaker Perspectives

• Host/reviewer: Emphasizes the value, finish, braking, climbing performance and readable display, while repeatedly criticizing the overly sensitive torque sensor and the limited distinction between sensor modes.
• Test rider (around 100 kg): Confirms that the bike climbs steep terrain easily and feels comfortable, but identifies the front suspension as the main weakness, particularly over larger bumps.
