The AGATTU 1.B ADVANCE model from Kalkhoff, launched in 2021, is a versatile e-bike that stands out for its comfortable features and modern technology. The frame is made of aluminium and is designated Bosch Comfort V1, indicating a comfortable riding position and high stability. The bike is powered by a Bosch Active Line Plus motor with an output of 250 watts and a torque of 50 Nm, which, in combination with a 500 Wh Li-ion battery, provides sufficient assistance on longer rides. The Bosch Intuvia LCD display, featuring a control panel and Walk Assist function, allows for easy control and monitoring of ride data.
Braking safety is ensured by the Magura HS11 hydraulic rim brakes, which are renowned for their reliability. The drivetrain consists of a Shimano Nexus 8-speed hub gear system, which enables smooth and precise gear changes. The SR Suntour CR-8V HLO fork, with 50 mm of travel, offers additional comfort by effectively absorbing bumps in the road.
The lighting system comprises a Herrmans H-Black MR8 LED front light and a Herrmans H-Trace LED rear light, which ensure good visibility in traffic. The Schwalbe Energizer Active Plus tyres in size 47-622 offer good grip and puncture protection, whilst the Concept rims with eyelets ensure durability. The Concept EX Metrostyle handlebars, paired with Ergon GC10 grips and an adjustable aluminium stem, allow for individual adjustment of the riding position.
The Selle Royal Nuvola Unitec saddle and the suspension-equipped Patent seatpost also contribute to a high level of riding comfort. Practical details such as the aluminium pedals with anti-slip coating and reflectors, the Racktime System Carrier luggage rack and the protective plastic mudguards with edge protection round off the specification. Priced at 2699 EUR, the AGATTU 1.B ADVANCE offers a balanced combination of comfort, performance and functionality, making it ideal for everyday use.
