TENWAYS Longtail Duo Electric Cargo Bike

Carry More. Go Further.

The Longtail Duo is built around an extra-long rear carrier that gives you plenty of room for passengers or cargo. TENWAYS has designed the bike to accommodate two children, while the versatile MIK-compatible rear system opens up plenty of options for carrying bags, shopping and other essentials. Family accessories including guard rails, seat cushions, spoke protectors and stepping boards make it ready for family adventures, while the front rack gives you another handy place to carry your everyday essentials. With a maximum permissible weight of 220kg including the bike, this is an electric cargo bike designed to handle serious everyday loads.

80Nm of Mid-Drive Power

Loaded up with children, shopping or both? No problem. The Longtail Duo uses a Bafang M410 250W mid-drive motor producing up to 80Nm of torque, giving you the assistance you need when pulling away, tackling hills or riding with a heavier load. Unlike a basic hub-motor setup, the mid-drive motor works through the bike’s drivetrain, making it particularly well suited to a cargo bike designed around carrying people and gear. An integrated torque sensor also helps deliver assistance naturally based on how you’re pedalling.

720Wh Battery for Bigger Days Out

A family cargo bike needs enough battery to keep up with family life. The Longtail Duo comes with a 720Wh removable lithium-ion battery, giving you a claimed range of up to 100km on a single charge under suitable conditions. The battery is neatly integrated into the frame but can be removed for convenient indoor charging. That means you can charge it at home without having to find a place to park the entire bike next to a socket.

Gates Carbon Belt + Enviolo Hub: Less Fuss, More Riding

One of the standout features of the TENWAYS Longtail Duo is its low-maintenance drivetrain. Instead of a traditional greasy bicycle chain, it uses a Gates CDX carbon belt drive, giving you a clean, quiet and durable way to transfer power to the rear wheel. It is paired with an Enviolo stepless hub, allowing you to change your gearing smoothly and continuously rather than jumping between traditional gears. In busy town centres, school runs and stop-start traffic, being able to adjust your gearing while stationary or under load is seriously useful.

A Cargo Bike That’s Actually Comfortable

Cargo bikes aren’t much use if every journey feels like hard work. The Longtail Duo features a suspension front fork to help smooth out bumps, 4-piston hydraulic disc brakes for controlled stopping and a comfortable Selle Royal saddle. The low-step design makes getting on and off easier, while the adjustable cockpit allows you to fine-tune your riding position. There’s also a heavy-duty kickstand to keep the bike stable when loading passengers or cargo.

Smart Security for Peace of Mind

The Longtail Duo isn’t just smart mechanically. Its TENWAYS Smart Connect system adds connected security features including GPS tracking, motion detection and a Notice Zone function, which can alert you if the bike moves outside a designated area. There’s also an ABUS frame lock for an additional layer of physical security. For a premium electric cargo bike that may become part of your family’s daily routine, those extra security features are a welcome addition.

School runs, supermarket trips, nursery drop-offs, commuting, weekend adventures and those journeys where the car normally gets the call – this is where a longtail cargo bike can really earn its place.
