The Hercules E-Imperial I-R5 from 2022 is a versatile e-bike that stands out thanks to its high-quality components and well-thought-out features. The frame is made from aluminium from the Trekking Sport Advanced series, featuring an integrated Powertube and a tapered headset, ensuring both stability and a modern design. The maximum load capacity is 170 kg, whilst the bike itself weighs 29 kg, indicating a robust construction.
Safety and control are provided by Shimano’s MT410 hydraulic disc brakes, featuring BL-MT402 brake levers and a large 180 mm front brake disc. The fork is an SR Suntour NEX-E25 HLO with 63 mm of travel, which can be adjusted and locked if required to optimise riding comfort on various surfaces.
The E-Imperial I-R5 is powered by Bosch’s third-generation Performance Cruise motor, which delivers 250 watts of power and 65 Nm of torque. The Bosch Powertube battery, with a capacity of 625 Wh, ensures an impressive range, whilst the Bosch Intuvia display allows for simple and intuitive control.
The bike is fitted with a Gates CDX drivetrain, which is renowned for its low maintenance and durability. The Samox EC38 crankset and the Gates CDX 28T sprocket complement this system perfectly. Additional comfort is provided by the Zecure HD handlebars with a 35° backsweep and 20 mm rise, as well as the ergonomic Ergon GP1 grips. The adjustable A-head stem allows for individual adjustment of the riding position.
The spec is rounded off by high-quality components such as the Ryde Andra 40 rims and Schwalbe Marathon Plus tyres with SmartGuard protection. The lighting comprises a HERCULES FH 100 LED front light with up to 100 lux and an Ivalo LED rear light integrated into the luggage rack. The Racktime luggage rack with SnapIt system offers additional flexibility for carrying luggage.
Other practical features include SKS plastic mudguards, a Horn Catena 08 chain guard, a Pletscher Comp Flex 40 kickstand and an ABUS Pro Shield 5850 lock, which is keyed alike with the battery lock. The Selle Bassano SUPREMA saddle and the Zecure HD001 seatpost ensure comfort on longer rides.
Priced at 4199 EUR, the Hercules E-Imperial I-R5 offers a well-thought-out all-round package for discerning cyclists who value quality and reliability.
