This video is an unboxing and hands-on review of the Cyrusher Zenith e-bike [00:32]. The blogger had previously completed long-distance trips on less cost-effective e-bikes, and this time, sponsored by the brand, tested the higher-spec Zenith.
After riding over 30 miles across various terrains (city roads, muddy roads, and off-road single-track tracks), the blogger gave it high praise: Although it appears large and heavy, its off-road handling is very agile, with strong torque, excellent value for money, and is extremely suitable for off-road adventures and bike packing [10:05, 18:00].
Pros and Cons Analysis
Pros:
-
Ample power and torque (especially off-road): The 95 N·m motor torque performs impressively on single-track off-road and steep slopes, with extremely fast acceleration response [03:19, 15:07]. 2. Smooth and Natural Handling: Supports torque/cadence sensing, intelligently outputting power based on pedaling effort, resulting in a very natural riding experience, unlike the abrupt “motor pulling the rider” feeling of some cheap electric bikes [01:10, 01:38].
-
Excellent Shock Absorption and Grip from Wide Tires: The wide 26x4.0-inch tires provide excellent grip on gravel and muddy surfaces, absorbing a significant amount of vibration. The hardtail design (no rear suspension) offers near-full front and rear suspension comfort [04:06, 14:14].
-
Surprisingly Agile: Despite its weight, the bike is agile and easy to handle on narrow, winding single-track trails [13:44, 18:10]. 5. Riding without motor assistance: On flat roads, when pedaling purely with the motor assistance off, the drag from the motor is almost imperceptible. The blogger was even able to easily reach nearly 20 mph (approximately 32 km/h) [09:32, 09:45].
-
Range and removable battery: The 780Wh LG battery delivers impressive range (tested at less than half power for 30 miles) and can be easily removed for indoor charging, making it extremely convenient for long-distance camping [05:06, 07:01].
-
Excellent brakes and detailed features: The 180mm hydraulic disc brakes provide excellent braking performance (very strong after break-in), and it comes with brake lights, a high-brightness LED headlight, a large color screen display, and a comfortable seat [00:51, 03:42, 06:30]. 8. Excellent value for money: Priced at approximately £1,200 under the direct sales model, its configuration and experience rival those of major brands priced at £2,400-£2,500 in dealerships [16:41, 17:03].
Cons:
-
No mudguards: The factory-installed rear mudguard results in significant mud splashing onto the rider’s back and backpack when riding on wet or muddy surfaces [02:56, 03:05].
-
The 7-speed cassette is slightly insufficient for hill climbing on paved roads: It uses a relatively entry-level Shimano Tourney 7-speed drivetrain. On steep inclines on paved roads, the gear ratios feel insufficiently close, requiring reliance on the electric assist for higher output [04:47, 17:20]. 3. No pump/pump included: Compared to other brands the blogger has purchased, this bike does not include a pump/pump (but the tool kit is complete) [02:09].
-
Slight pulling sensation when braking: Due to the single-sided disc brake and the structure of the fat tire, the front wheel feels slightly pulled to the left when braking hard [11:32].
[00:00:00 - 00:02:00] Introduction and appearance configuration: The blogger introduces the background and showcases the Cyrusher Zenith electric-assist fat tire mountain bike [00:32].
Basic specifications are introduced: front suspension, hardtail, 4-inch wide tires, 180mm hydraulic brakes, locking rubber grips, built-in battery design [00:38, 00:58].
It emphasizes its sensor modes (torque/cadence), and the pedaling feel is extremely natural [01:10]. [00:02:01 - 00:04:00] Assembly Details, Battery, and Shortcomings:
Assembly takes approximately 1 hour and includes a complete set of assembly and maintenance tools [02:01].
Complaints: The original bike lacks mudguards, resulting in getting covered in mud while riding on wet roads [02:56]; no air pump or bike lock is included [02:09].
Equipped with an LG battery, the controller is intuitive (5-level assist + push mode), and the lights are easy to turn on [02:21, 02:50].
The seat comfort is better than the average for its price range [03:24].
[00:04:01 - 00:07:28] Bike Details and Specifications:
Dashboard: A large, clear color LCD screen, like a small iPad [03:42]. Suspension and Wheels: 26x4.0 fat tires provide both grip and micro-dampening; front fork travel approximately 75mm, with preload adjustment and lockout support [04:06, 04:40].
Drivetrain and Powertrain: Shimano 7-speed gearbox [04:47]; 780Wh removable battery for convenient long-distance charging [05:06]; UK-compliant 250W rear motor (speed limited to 15.5 mph, no pure throttle) [05:40].
Frame and Safety: 30-inch stride height for good adaptability; features a dual downtube frame structure, high-brightness LED headlight, and brake taillight integrated into the rear fork [05:49, 06:30, 06:40].
Reputed range of 60 miles; the blogger’s actual test showed only half the battery was used for 30 miles [07:01]. [00:07:29 - 00:09:08] Paved Road Riding and Acceleration/Braking Tests:
Starting on Flat Road: Rapid acceleration to the 15 mph electric assist limit within seconds [07:44, 08:14].
Braking Test: With the brake pads broken in, the 180mm hydraulic disc brakes performed very well, with the brake lights illuminating simultaneously [08:41, 09:00].
[00:09:09 - 00:12:40] No-Electric Towing Test and Road Riding Experience:
No-Power Test: With the electric assist set to 0, there was no noticeable resistance when pedaling on flat roads, and it was even easy to reach 17-20 mph [09:23, 09:45].
The frame has ample space, making it extremely suitable for carrying bike packs for long-distance camping [10:05]. When climbing hills on highways, the torque sensor dynamically distributes power in real time based on pedal pressure [11:03].
A slight leftward veer is observed when braking hard [11:32].
[00:12:41 - 00:16:40] Off-road test (muddy road/single-track): The headlights’ nighttime/darkness illumination was tested; all four LEDs were extremely bright [12:42].
Off-road performance is impressive: handling is surprisingly flickable, and cornering is agile [13:44, 13:57].
The wide tires effectively absorb gravel and road bumps, feeling like riding a full-suspension bike [14:14].
The powerful 95 N·m torque is continuous on steep off-road slopes and corners, even feeling “a bit excessive” [15:07, 15:43]. [00:16:41 - 00:18:39] Summary and Purchase Recommendation: Priced at only around £1,200, its direct sales model makes it far superior in value to comparable models sold in traditional dealerships for £2,400+ [16:41, 17:03].
In summary: Although it has a 7-speed transmission and no rear fenders, its off-road performance is extremely fun, lightweight, and agile, making it highly recommended for camping and adventure [17:20, 18:10].
