The 2021 Conway Cairon S 627 is a versatile e-bike that stands out for its high-quality components and robust construction. The aluminium frame elegantly integrates the Bosch Intube battery, giving the bike a modern and clean-cut design. The maximum permissible weight is 130 kg, making it a solid choice for a wide range of uses.
The Cairon S 627 is powered by a powerful fourth-generation Bosch mid-drive motor, the Performance CX, which operates at 250 watts. The battery has a capacity of 625 Wh, providing sufficient power for longer rides. It is controlled via the Bosch Kiox display, which is equipped with a 4-level remote control and a push-assist function.
Safety is ensured by Shimano’s BR-MT410 hydraulic disc brakes, which, in combination with the BL-M4100 brake levers, deliver reliable braking performance. The brake discs measure 203 mm at the front and 180 mm at the rear, ensuring effective deceleration even at higher speeds.
The drivetrain consists of a 12-speed SRAM SX Eagle system, operated via an SX Eagle trigger shifter. This drivetrain offers a wide gear range, making it suitable for various types of terrain. The FSA crankset and Bosch bottom bracket contribute to the efficiency of the drivetrain.
The suspension is complemented by the RockShox Recon Silver RL fork with 120 mm of travel, ensuring comfort and control on uneven terrain. The wheels are fitted with Schwalbe Smart Sam tyres, mounted in size 65-584 at both the front and rear, which impress with their foldability and versatility.
Other features include a Conway Riser handlebar with a diameter of 31.8 mm and a width of 720 mm, as well as Conway Sport fix grips. The saddle is a Selle Royal Vivo Athletic Ergo model, mounted on a Conway Patent seatpost with a diameter of 31.6 mm.
Priced at 3,399 euros, the Cairon S 627 is an attractive option for anyone looking for a high-performance, well-equipped e-bike that is suitable for both everyday use and sporty rides.
