Cyrusher Flex, a full-suspension electric mountain bike featuring front and rear suspension, a clean frame design with hidden welds [18:45], and a unique dual-system option allowing riders to switch between a torque sensor and a cadence sensor for the electrical assistance [00:20].
Key Specifications & Price:
Motor & Battery: Powered by a 250W rear-hub motor (delivering up to 87 Nm of torque in Europe) [01:33] and a 48V, 720Wh (15 Ah) removable lithium battery [01:58].
Weight & Price: The bike weighs 31 kg (with the 3.9 kg battery) [02:36]. It is priced around €1,499 on promotion (normally €1,799) [19:33].
Features & Performance:
Dual Sensor System: Riders can easily switch between a torque sensor (for natural, effort-proportional assistance, ideal for hills and rough paths) and a cadence sensor (for effortless pedaling on long, flat stretches) [05:07].
Comfort & Handling: Equipped with front and rear air suspension (DNM rear shock), Logan hydraulic disc brakes with 180mm rotors [03:18], and an 8-speed Shimano drivetrain [03:03]. The suspension offers an exceptionally smooth ride over cobblestones and rough trails, though the rear shock may feel a bit bouncy/soft out of the box and requires proper air-pressure adjustment for the rider’s weight [11:44].
Pros and Cons:
Pros: Highly versatile and exceptionally comfortable on varied terrain (roads, cobblestones, and trails), excellent build quality and finish with hidden welds, natural-feeling torque sensor, and the flexibility to switch to a cadence sensor.
Cons: Heavy at 31 kg (making it harder to carry without power or transport), basic battery indicator lacks precise percentage readouts, and the rear suspension requires initial pressure tuning to prevent pedal bobbing.
