The “Robert/a F7 Active Plus 400” model from Hercules, released in 2022, is a versatile and robust e-bike that stands out for its well-thought-out features and solid build quality. The frame is made from Aluminium Trekking City, AL 6061, which gives the bike stability and good balance. With a maximum load capacity of 135 kg and a kerb weight of 27 kg, the bike is well suited to everyday use.
The Magura HS-11 hydraulic rim brakes ensure reliable braking performance, whilst the Shimano Revoshifter gear levers allow for precise and easy gear changes. The SR Suntour CR85-E25 P fork, with 63 mm of travel, offers additional comfort on uneven roads and is also adjustable. For road safety, the bike is fitted with a Comus F16 LED front light, which provides up to 20 lux, as well as a Comus R-232EB rear light for the luggage rack.
The bike features non-slip Wellgo C-157 pedals and an FSA CK-220 crankset. Power is transmitted via a KMC Z1EHX chain. The handlebars – a Kalloy Tour AL with a width of 660 mm and a 37° backsweep – ensure a comfortable riding position in combination with the Ergo 2D grips. The Kalloy AL-822 stem is adjustable to facilitate customisation to individual needs.
The DBM-2 rims are fitted with Supero 50-622 tyres, which impress with their Optima safe puncture protection. The front hub is a Formula OV-31 with a quick-release mechanism, whilst the rear wheel is fitted with a Shimano Nexus 7-speed hub and freehub. The DDK City DDK-225A2 saddle and the rigid Kalloy SP-F102 seatpost provide comfort on longer rides.
Other practical features include plastic mudguards with V-struts, a Horn Catena 18 chain guard, a Standwell SW-RA031J kickstand and an AXA battery lock. The i-Rack system carrier with spring-loaded flap offers additional transport options.
Power is provided by an Active Plus GEN3 motor with 250 watts and 50 Nm of torque, powered by a Bosch carrier-type battery with a capacity of 400 Wh. The Bosch Intuvia display allows for easy control and viewing of key riding information. The bike comes with a Bosch 2A charger.
Priced at 2599 EUR, the Hercules Robert/a F7 Active Plus 400 offers excellent value for money for anyone looking for a reliable and comfortable e-bike for urban use.
