The "Cairon S 629" model from Conway, launched in 2021, is a versatile e-bike equipped with a wide range of technical features that make it suitable for both everyday use and more demanding tours. The frame is made of robust aluminium and seamlessly integrates the Bosch Intube battery, giving the bike a clean and modern look. With a maximum load capacity of 130 kg, the bike is stable and robust.
The Cairon S 629’s braking system utilises tried-and-tested Shimano technology. The ‘BR-MT410’ hydraulic disc brakes, with 203 mm front and 180 mm rear rotors, ensure reliable stopping power in a variety of conditions. The bike is fitted with the SRAM “SX Eagle” 12-speed drivetrain, which enables precise gear changes. The “SX Eagle Trigger” shifter assists the rider with a single-click function.
Comfort and control are provided by the ROCKSHOX “Recon Silver RL” suspension fork with 120 mm of travel, which effectively absorbs bumps on rough terrain. The bike is fitted with VP “VPE-506” pedals and an FSA “CK-745” crankset, which features a 38-tooth chainring configuration. The SRAM “PG 1210 Eagle” cassette offers a range from 11 to 50 teeth, allowing for flexible adaptation to different riding conditions.
The handlebars are CONWAY risers with a diameter of 31.8 mm and a width of 720 mm, complemented by CONWAY “Sport fix” grips for optimum grip. The stem also has a diameter of 31.8 mm. The sturdy CONWAY “X18” hollow-section rims are designed for use with disc brakes and fitted with SCHWALBE “Smart Sam” tyres, which are mounted in size 65-622 at both the front and rear.
At the heart of the Cairon S 629 is the powerful fourth-generation BOSCH mid-drive motor, the “Performance CX”. With a voltage of 36 V and an output of 250 W, it provides powerful assistance when needed. The accompanying BOSCH PT lithium-ion battery, with a capacity of 625 Wh, ensures an impressive range. The BOSCH “Kiox” display allows for intuitive control via four assistance levels and offers a push-assist function.
The price of the Cairon S 629 is €3,399, which represents excellent value for money given its high-quality specifications. The model impresses with its well-thought-out combination of performance, comfort and functionality, making it an excellent choice for e-bike enthusiasts.
