The 2021 "Cairon X 300" model from Conway is an e-bike that stands out for its well-thought-out specifications and robust construction. Priced at 2,999 EUR, it offers a wide range of features that enhance both comfort and performance. The bike’s frame is made of aluminium and is specifically designed to integrate the Bosch Intube system, giving the bike a modern and sleek appearance. The maximum load capacity is 130 kg, ensuring a robust construction and high load-bearing capacity.
Braking performance is provided by the TEKTRO “HD-T390” system, which is fitted to both the brakes and the brake levers. The front and rear brake discs have a diameter of 180 mm, ensuring reliable deceleration. Gear changes are handled by the SHIMANO “Deore RD-M5120 Shadow Plus” 10-speed system, which, in combination with the SHIMANO “Deore SL-M4100” shifter, enables precise and smooth gear selection.
Front suspension is provided by the RST “Blaze MLO” fork with 80 mm of travel, ensuring comfort on uneven terrain. Power is transmitted via the FSA “CK-745” crankset, which is 170 mm long and features a 38-tooth chainring. The SHIMANO “CS-M4100” cassette offers a range from 11 to 46 teeth, and power is transmitted via the KMC “X10EPT” chain.
The handlebars – an ERGOTEC “Low Riser” with a diameter of 31.8 mm and a width of 720 mm – and the adjustable ERGOTEC “Octopus” stem contribute to a comfortable riding position. The SELLE ROYAL “Vivo Athletic Ergo” saddle, together with the CONWAY Patent seatpost, provides additional comfort. The rims are CONWAY hollow-section “X6” disc rims, and the tyres are CONTINENTAL “X-King” in size 55-622. The hubs are by SHIMANO and fitted with quick-release mechanisms, making it easy to change wheels.
The Cairon X 300 is powered by a fourth-generation BOSCH “Performance CX” mid-drive motor, which operates at a power output of 250 W at a voltage of 36 V. The accompanying battery is a BOSCH PT lithium-ion model with a capacity of 625 Wh, which enables a considerable range. The BOSCH “Intuvia” display offers intuitive control with four assistance levels and a push-assist function.
In summary, the Conway Cairon X 300 is a well-equipped e-bike which, thanks to its high-quality technology and well-designed components, represents a reliable choice for discerning riders.
