Description

The Conway Cairon C 4.0 B is an electric SUV bike built around everyday practicality. The step-through aluminium wave frame makes mounting and dismounting effortless, and the bike is available in sizes S through XL to suit a wide range of riders. The adjustable Satori stem lets each rider dial in their preferred riding position.

The Bosch Performance Line PX mid-drive motor produces 90 Nm of torque, providing natural, responsive support from the first pedal stroke — whether you're climbing a hill, battling a headwind, or carrying a load. The Bosch PowerTube 800 Wh battery sits neatly inside the frame, keeping the bike's weight centred and its silhouette clean. Everything is managed through the Bosch Kiox 300 colour display, part of the Bosch Smart System ecosystem.

The Gates CDX belt drive paired with the Shimano Nexus SG-C7000-5D internal 5-speed hub eliminates the usual chain maintenance: no oil, no rust, no skipped gears. Gear changes are made via the Shimano Revoshift twist shifter, either rolling or at a standstill. Schwalbe Smart Sam 27.5" tyres (60-584) handle varied surfaces, supported by the Suntour XCM34 fork with 120 mm of travel.

Standard equipment covers the practical bases: Conway MIK rear rack with spring clip, Curana Apollo 75 mudguards, battery-powered Contec Prisma 90 E+ front light, Contec Z-Stripe rear light, and an Ursus Mooi Plus kickstand. Maximum system weight is rated at 140 kg.

Bosch Performance Line PX - 90 Nm

Between power and fullness. The Bosch Performance Line PX is Bosch's newest motor, designed for everyday adventurers and frequent bike travelers. With 90 Nm of torque and up to 700 W of power, it is positioned between the Performance Line CX and the classic Performance Line — offering the best of both worlds: power for demanding terrain, silence to enjoy the journey. Developed specifically for trekking and touring bikes, the PX is distinguished by its remarkable acoustic discretion. The engine fades away to let you hear nature, towns and paths - while being there, silently powerful, as soon as the road gets rough. eShift technology automatically manages gear changes to maintain optimal cadence, while Bosch ABS ensures maximum safety, even on wet roads or with heavy luggage.

Bosch PowerTube 800 Wh

Uncompromising autonomy. The Bosch PowerTube 800 Wh is the battery that frees cyclists from the constraint of mileage. With 800 Wh of capacity, it pushes the limits of every outing — whether it's a long commute, a weekend getaway or a multi-day wilderness adventure. Integrated directly into the frame tube, the PowerTube disappears into the silhouette of the bike for a clean aesthetic and optimal protection against shocks and bad weather. Light for its capacity, it recharges quickly and pairs perfectly with all Bosch Smart System motors for intelligent energy management in real time.

Bosch Kiox 300

Information, without compromise. The Bosch Kiox 300 is the connected screen that strikes the right balance between readability, compactness and functionality. Mounted on the handlebars, it displays all the essential data of your ride on a clear and readable backlit screen - even in direct sunlight - without cluttering the cockpit. Connected to the eBike Flow app via Bluetooth, it provides access to software updates, personalization of riding modes and detailed monitoring of your performance. Easy to use, it is aimed at both urban cyclists and demanding hikers who want to keep an eye on their data without complicating their lives.
