The 2021 Cairon T 550 LL from Conway is a versatile e-bike which, at a price of 3,799 EUR, is positioned in the mid-range price segment. The bike’s frame is made from a sturdy aluminium Intube Wave Bosch design, which supports a maximum load of 130 kg. Braking performance is provided by TEKTRO ‘HD-T390’ brakes with 180 mm brake discs at both the front and rear, ensuring reliable deceleration.
The Cairon T 550 LL’s gear system is controlled by a SHIMANO “Nexus” 5-speed system with the “SLC-7000” gear lever, enabling precise and easy gear selection. The ROCKSHOX “Recon Silver RL” fork, with 80 mm of travel, provides additional comfort and control on uneven terrain. The bike is lit by the CONTEC “LED Aurora 100 E+ 40” front light and an AXA “Blueline” LED rear light, which ensure good visibility in low-light conditions.
The Cairon T 550 LL is powered by a fourth-generation BOSCH mid-drive motor, the “Performance CX”. It operates at a voltage of 36 V and has an output of 250 W. The accompanying BOSCH PT lithium-ion battery, with a capacity of 625 Wh, provides sufficient power for longer rides. The BOSCH “Kiox” display, featuring 4 modes, remote control and push assist, offers the rider intuitive control and key information at a glance.
Other features include the FSA “CK-745” crankset, which is 170 mm long and has a 38-tooth chainring, complemented by a SHIMANO 27-tooth chainring. The handlebars are ERGOTEC “Ladytown”, whilst the stem is an adjustable model called “Octopus”. The rims are CONWAY hollow-section “X6” discs, fitted with SCHWALBE “Energizer Active Plus” tyres for both the front and rear wheels, which are renowned for their good grip and durability.
Comfort is ensured by the SELLE ROYAL “Vivo Moderat Ergo” saddle and the ERGOTEC “SP10” seatpost. Plastic mudguards from SKS, a HESLING Move chain guard and an URSUS aluminium kickstand complete the specification. For added security, an AXA “Bock XXL” lock is fitted, whilst the ATRAN “Cummute Pro” luggage rack with spring-loaded flap offers practical transport options. The Cairon T 550 LL is therefore a well-equipped e-bike that performs well both in the city and on longer rides.
