The host tests the Cyrusher Flex electric mountain bike (VTT) in the Pyrenees mountains [00:00]. He first unboxes and assembles the bike with the included tool kit, noting that it comes very well packaged and includes a helpful French manual [02:25].

Bike Specifications & Features:

Battery & Range: The 4 kg, 15 Ah battery provides an estimated range of up to 90 km (around 70 km in practice depending on assistance levels and terrain) [00:54]. It takes about 7 hours for a full 0–100% recharge [02:08].

Motor & Transmission: Features a 250W motor and an 8-speed Shimano transmission [01:23].

Assistance Modes: Offers two pedal-assist modes—cadence (assists as soon as you pedal) and torque (assistance scales proportionally with how hard you push the pedals) [01:40].

Mountain Testing & Performance:

The host takes the 34 kg bike on steep, rugged mountain roads [05:18].

He praises the excellent front and central suspension systems, disc brakes, and comfort, noting that despite the bike’s heavy weight, it handles very well and feels agile [05:31].

He highlights the difference between the torque mode (which requires more physical effort on steep inclines) and the cadence mode (which makes climbing much easier with minimal effort) [08:31].

Battery Consumption & Practicality: After riding about 30 km through grueling mountainous terrain, the battery only dropped by about a quarter, demonstrating solid real-world efficiency [10:18].

Conclusion: The host concludes that the Cyrusher Flex is an unexpectedly comfortable, highly fun, and versatile leisure electric mountain bike that handles rugged terrain well while remaining practical [10:54].
