• Weight: 33.4 kg.
• Motor and battery: Rear 250 W motor with 95 Nm of torque, paired with a removable 52 V, 15 Ah battery. The manufacturer claims a range of up to 96 km for a 75 kg rider. Charging takes around 7.5–8 hours with the included 2 A charger.

• Weather caution: The reviewer describes the bike as IP4-rated and advises against riding in heavy rain or pressure washing it.

User Experience

Assembly was straightforward: the handlebar, pedals, and front wheel needed to be fitted. The wheel uses two small bolts rather than a conventional axle rod. The bike arrived well packed, and the reviewer found no need to adjust the gears or brakes. The tires did need inflating.

The bike felt very powerful and responsive, especially with assistance engaged. It climbed steep hills easily, and the reviewer found it comfortable on trails and roads despite the lack of rear suspension. The front fork, soft saddle, and tire pressure help absorb bumps.

The motor was quiet, the brakes worked well, and the gears shifted smoothly. Despite its size and weight, the bike was described as maneuverable and enjoyable to ride. On smoother roads, locking the front fork was said to improve pedaling efficiency.

The reviewer preferred torque-sensor mode, which felt more natural and provided better control. Cadence mode can launch the bike with only a small pedal movement, so both reviewers advised caution—particularly when handling the bike or riding near hazards.

The fat tires were considered suitable for paths and the trails tested, but not especially aggressive off-road tires. The reviewer cautioned against riding in very wet or muddy conditions.

Without assistance, the bike’s weight makes it hard work to pedal, especially uphill.

Pros

• Strong acceleration and excellent hill-climbing, helped by the 95 Nm torque.
• Natural, controllable assistance in torque-sensor mode.
• Comfortable and capable on roads and moderate off-road routes.
• Effective hydraulic brakes, smooth shifting, and a quiet motor.
• Useful display, removable battery, and practical accessory mounting options.
• Considered good value by both reviewers at around €1,200–€1,249.

Cons and Cautions

• Heavy at 33.4 kg and difficult to ride without assistance.
• Cadence mode can engage abruptly and may surprise the rider.
• No rear suspension; comfort depends partly on the fork, saddle, and tire pressure.
• The tires are not intended for especially demanding or muddy off-road riding.
• Avoid heavy rain and pressure washing, according to the reviewer.

Comparisons and Verdict

The reviewers compared the bike’s 52 V setup with the Cyrusher Comoda Pro, describing both bikes as particularly lively and powerful. They also contrasted the Zenith’s 26-inch fat tires with the Comoda’s 20-inch wheels.

No formal numerical score was given, but the father and son both called it a favorite and recommended it enthusiastically—“100%” approved—especially for riders seeking a powerful, comfortable fat bike for trails and general riding.

Different Speakers’ Views

• Tom, the father: Emphasized the bike’s power, hill-climbing, comfort, and off-road enjoyment; he struggled to identify any major drawbacks.
• Lucas, the son: Praised the responsiveness, brakes, shifting, riding position, and handling, and highlighted the need for caution with cadence mode.
