The "Robert/a HD I-F5" model from the Hercules brand from 2024 is a high-quality eTrekking bike that is characterised by its robust construction and modern features. The frame is made from the eTrekking R22-Series AL6061, an aluminium frame designed for durability and stability. The permissible total weight is 180 kg, while the bike itself weighs 28 kg. It is designed for a height between 160 cm and 170 cm, making it ideal for a wide target group.
Safety is ensured by the Shimano MT410 hydraulic disc brakes, which are equipped with 180 mm brake discs at both the front and rear. The brake levers are also from Shimano, model BL-MT401, and offer reliable braking performance. The gear system is a Shimano Nexus 5-speed with freewheel, which is operated via the Shimano SL-C7000-5 gear lever.
The SR Suntour MOBIE E-25 fork with 63 mm travel and air suspension ensures a comfortable ride, especially on uneven surfaces. The lighting is optimally equipped with the Hercules FF-100 front light, which has a daytime running light sensor and high beam and offers up to 150 lux, and the Comus RZ-100 rear light with COB LED technology.
The drive is provided by a Gates CDX system with a 30T sprocket and an FSA CK-220 crankset. The handlebar is a Trekking Zecure made of aluminium with a 35° backsweep and a width of 640 mm. The grips are ergonomically designed and have an integrated clamp. The adjustable stem, model Zecure UP2+, allows you to customise your riding position.
The tyres are Schwalbe Marathon Efficiency tyres with RaceGuard and Performance features, which are mounted on Ryde Andra 40 rims. The hubs are from Shimano, with the front hub being the HB-TC500 model and the rear hub SG-C7000-5D.
The Selle Bassano Suprema 3Zone City saddle together with the BySchulz G2 seat post with 30 mm suspension travel provide additional comfort. Practical features such as the SKS EDGE AL 66 R mudguards, the ABUS IT3 battery lock and the Monkey Load pannier rack round off the overall package.
The bike is powered by a Bosch Performance Line CX Smart System motor with 250 watts and a torque of 85 Nm. The Bosch PowerTube battery has a capacity of 750 Wh and is charged via a Bosch 4A charger. The Bosch Intuvia 100 display provides all important information during the ride.
