The "Cairon C 329" model from Conway, launched in 2021, is a versatile e-bike characterised by its robust construction and modern features. The frame is made of aluminium and is specifically designed for the fourth-generation Bosch mid-drive motor, which operates at a power output of 250 watts and a voltage of 36 volts. The motor is powered by a Bosch lithium-ion battery with a capacity of 500 Wh, providing reliable assistance for longer rides. The bike’s maximum permissible weight is 130 kg, making it suitable for carrying heavier loads.
The Cairon C 329’s braking system consists of TEKTRO “HD-T390” brakes and brake levers, which, together with the 180 mm TEKTRO “TR180 2.3” brake discs at the front and rear, ensure safe deceleration. The bike is fitted with the SHIMANO “Deore RD-M5120 Shadow Plus” derailleur, which has ten gears and is operated via the SHIMANO “Deore SL-M4100” shift lever. The RST “Blaze MLO” fork offers 120 mm of travel, providing extra comfort on uneven terrain.
The e-bike is fitted with a HERRMANS “MR GO 30” front light and an AXA “Blueline” LED rear light, which ensure good visibility when riding at night. Other features include VP “VPE-506” pedals, an FSA “CK-200” crankset with 38 teeth and a SHIMANO “CS-M4100” cassette with a range of 11–46 teeth. Power is transmitted via a KMC “X10EPT” chain.
The handlebars are LEVEL 9 “Low Riser” with a diameter of 31.8 mm and a width of 720 mm, complemented by CONWAY “Sport fix” grips. The LEVEL 9 “Adjustable” stem allows for individual adjustment of the riding position. The bike is fitted with CONWAY “X17” hollow-wall rims and IMPAC “Ridgepac” tyres, which are size 57-622 at both the front and rear and feature reflective strips.
Other practical features include a SELLE ROYAL “Vivo Athletic Ergo” saddle, a CONWAY patented seatpost with a diameter of 31.6 mm, SKS plastic mudguards and an URSUS aluminium kickstand. The ATRAN “Cummute Pro” luggage rack with spring-loaded flap provides additional storage space. The motor is controlled via the BOSCH “Intuvia” display, which offers four assistance levels and a push-assist function.
The Cairon C 329 is priced at 2799 EUR and is a solid choice for cyclists who value quality, comfort and modern technology.
