The Hercules ROB SL F5 is light, quiet, and elegant — a sporty-clean design with maintenance-free technology. The Bosch Performance Line motor delivers 75 Nm of torque smoothly and dynamically. The compact 400 Wh Bosch CompactTube battery is elegantly integrated into the downtube and can be expanded with the PowerMore Range Extender for additional range. The Gates CDC belt runs cleanly and silently, while the Shimano Nexus 5-speed hub with freewheel ensures smooth, reliable shifting. Comfort comes from the Suntour suspension fork (63 mm travel), Tektro hydraulic disc brakes, Schwalbe Marathon Almotion Evo tires, and a Selle Royal saddle. Weighing from 21.5 kg (without pedals), the ROB SL F5 is a lightweight urban e-bike, ready for commuting, errands, and city rides.
