This video is a detailed review of the Cyrusher Flex e-bike. The video blogger comprehensively evaluates the performance of this e-bike through actual riding tests (including steep slopes, narrow off-road tracks, and roads) and detailed explanations of the bike’s features.
Below is a summary of the video, an analysis of its strengths and weaknesses, and a breakdown by time period:
I. Core Summary of the Video
Model Positioning: The Cyrusher Flex is an “economical off-road e-bike,” priced at approximately £1,400, and complies with UK/European street safety standards (speed limit 15.5 mph / approximately 25 km/h).
Key Highlights: Equipped with both a torque sensor and a cadence sensor for dual-mode operation, it offers rapid power response, excellent full suspension, and extremely high value for money.
II. Advantages and Disadvantages Analysis
Advantages (Pros)
Sensitive Power Response: Equipped with a torque sensor, power is delivered instantly with a single pedal stroke, linearly adjusting to pedal force, resulting in an excellent start and climbing experience [01:09].
Strong Suspension and Comfort: Full suspension design (DNM rear shock + lockable front fork), combined with 27.5×2.6-inch wide tires, effectively filters rough road surfaces [02:35], [11:00].
Safety and Abundant Accessories: Logan hydraulic brakes offer excellent braking performance [03:40]; the seat is very comfortable [04:33]; it comes with a brake taillight [14:44]; an air pump and tool kit are included [18:30].
Reliable shifting and range: The Shimano 8-speed gearbox shifts smoothly [06:36]; the 48V 15Ah high-capacity battery provides an estimated range of 30–40 miles (approximately 48–64 km) [16:50].
High value for money: It features high-spec components for its price range (around £1,400) [13:26].
Cons:
Slightly noisy motor: The motor emits a noticeable high-frequency “humming” sound during riding [09:55], [11:12].
Cadence mode has a delay: When switching to Cadence cadence mode (cruise mode), there is approximately a 2-second delay in power output, resulting in a poor hill start experience [08:38].
Some accessories require additional purchase: Mudguards and a rear rack require extra payment [06:21]. III. Video Content Summary by Time Segment
[00:00:00 - 00:01:20] Initial Riding Impressions
Introduces vehicle legality (compliant with UK 15.5 mph speed limit) and sensor type, pointing out that the torque sensor provides a more natural response than a standard cadence sensor.
[00:01:21 - 00:05:40] Off-Road Slope and Narrow Track Testing
Conducted on steep slopes and a technically challenging narrow track (Singletrack). Successfully climbed the slope using 3-level assist mode; tested the braking power of the Logan hydraulic brakes and praised the comfortable seat.
[00:05:41 - 00:07:45] Mid-Route Stops and Initial Configuration Overview
Showcases the vehicle’s exterior, introducing the 48V 15Ah embedded battery, DNM rear suspension, 27.5×2.6 off-road grip tires, Shimano 8-speed derailleur, and optional rear rack and mudguards.
[00:07:46 - 00:10:35] Road Top Speed and Cadence Mode (Cruise) Test
Top speed was tested on flat roads (automatic power cut-off at 15.5 mph). Cadence mode was tested (triple-click power button to activate), and the noticeable delay was observed; torque mode is recommended instead. The motor noise was also noted to be a bit loud.
[00:10:36 - 00:13:00] Advanced Off-Road and Overall Riding Evaluation
Riding on potholes and dirt roads, the tire grip and suspension’s ability to absorb vibrations were praised. Aside from motor noise, there were almost no significant shortcomings.
[00:13:01 - 00:19:28] Detailed Disassembly and Function Demonstration in the Workshop
Back in the workshop for a detailed full-bike demonstration:
Suitable for riders of various heights: Adjustable seatpost, suitable for riders of 5’2"–6’0"+ [13:56].
Lighting and Instruments: Demonstrates front and rear lights and a high-brightness taillight, and shows how to operate the color display (mode switching, push assist, etc.) [14:44], [15:55].
Battery Removal: Demonstrates how to use the key to remove/install the lower tube battery, explaining that it supports charging on the bike and separately [17:47].
Unboxing Gifts: Showcases the included air pump, tool kit, and charger [18:30].
Summary and Conclusion: The blogger believes the Cyrusher Flex is one of the best motorcycles he has ever ridden, highly competitive in its price range, and strongly recommends it to riders who need to balance daily commuting and light off-road riding [19:05].
