The 2023 Hercules Intero I-R8 is a high-quality e-trekking bike that impresses with its well-thought-out features and solid build quality. The frame is made from eTrekking R9-Series aluminium (AL 6061), which gives the bike a robust structure whilst keeping the weight down to 26 kg. The maximum load capacity is 135 kg, providing ample space for both rider and luggage.
The Intero I-R8’s braking system is fitted with Tektro hydraulic disc brakes, featuring a 180 mm front rotor and a 160 mm rear rotor. The Shimano BL-MT201 brake lever ensures reliable and precise braking force transmission. Gear changes are handled by a Shimano Nexus 8-speed hub gear system with a coaster brake, controlled by a Shimano Revoshifter, providing a convenient and low-maintenance solution for everyday use.
Comfort on uneven terrain is ensured by the SR Suntour NEX fork with 63 mm of travel, which also features a lockout function and is adjustable. Lighting is provided by a HERCULES FH 40 LED front light with up to 40 lux and a Busch & Müller Toplight 2C LED rear light, ensuring good visibility in the dark.
The bike is powered by a GX Force Eco FIT motor with an output of 250 watts and a torque of 60 Nm. The motor is powered by a FIT Intube battery with a capacity of 630 Wh, which provides sufficient energy for longer rides. The Fit Display Compact allows for easy monitoring of the key riding parameters.
Other features include a Selle Bassano Volare XL City saddle, mounted on a Kalloy SP-383 seatpost with 45 mm of travel, and an adjustable A-Head stem. The Schwalbe Energizer Active Plus tyres with GreenGuard technology (50-622) offer excellent puncture protection and good grip. An i-Rack system carrier with a spring-loaded flap ensures that luggage can be transported safely.
The Hercules Intero I-R8 is available from 3699 EUR and offers a balanced combination of comfort, performance and functionality, making it an attractive choice for commuters and leisure cyclists.
