The "Cairon TR 4.5 Wave" model from Conway, launched in 2024, offers a balanced blend of comfort, performance and functionality at a price of 3599 EUR. The frame is made of aluminium and is specifically designed as a ‘Wave’ variant with a frame height of 42 cm, allowing for easy mounting. The maximum load capacity is 130 kg, whilst the bike itself weighs 29 kg, which is attributable to its robust construction and extensive range of features.
The Cairon TR 4.5 Wave’s braking system is fitted with TEKTRO “HD-T280” brakes, which provide reliable stopping power at both the front and rear. The brake discs measure 180 mm at the front and 160 mm at the rear, ensuring effective deceleration. The gear system consists of a 5-speed SHIMANO “Nexus” RBN with the SHIMANO “Alfine SL-C7000” gear lever, which allows for easy and precise gear selection.
Suspension is provided by the RST “Blaze ML” fork with 80 mm of travel, ensuring a comfortable ride even on uneven terrain. In terms of lighting, the bike is fitted with the CONTEC “DLUX 50 E+” front light and the CONTEC “CTL 335 E” rear light, both of which ensure good visibility in the dark.
Power is provided by a third-generation BOSCH “Performance” mid-drive motor with an output of 250 W and a voltage of 36 V. The battery, a BOSCH “Powertube 625” with a capacity of 625 Wh, provides sufficient power for longer rides. The BOSCH “Kiox” display, featuring four levels and a remote control, allows for easy control and monitoring of ride data.
Comfort is ensured by the SELLE ROYAL “Vivo Moderat Ergo” saddle and the HUMPERT “Ergotec SP10” seatpost. The HUMPERT “Ergotec Ladytown” handlebars and the adjustable HUMPERT “Ergotec Octopus” stem also contribute to a comfortable riding experience.
With CONTINENTAL “Contact Urban” tyres fitted to CONWAY hollow-section “X17” rims, the bike offers a stable and safe ride. The ATRAN “Cummute Pro” luggage rack with spring-loaded flap and the AXA “Bock XXL” lock are practical additions for everyday use.
Overall, the Cairon TR 4.5 Wave is a well-designed e-bike that stands out thanks to its high-quality components and powerful drive system, making it ideal for commuters or leisure cyclists who value comfort and reliability.
