Electric Cargobike – Ultimate Curve – Mid engine

Electric Cargo Bike – Ultimate Curve – Mid Engine

The Ultimate Curve – Mid Engine is Amcargobike’s most advanced electric cargo trike, offering pedal assist up to 15.5 mph (25 km/h) – the maximum legal speed for e-bikes on UK roads. It’s powered by a robust 250W mid-drive (crank) motor delivering an impressive 120Nm of torque for a smooth, natural riding experience and exceptional hill-climbing ability.

Featuring a sleek slimline frame in matte black, a high-capacity 14Ah (504Wh) battery, and the latest Anti-Tilt steering system, the Ultimate Curve is designed for both everyday commutes and longer family outings. The battery offers a range of up to 65 km (40.4 miles), even in colder weather.

Mid-Drive Performance & Control
The centrally mounted mid-drive motor ensures optimal weight distribution and a more intuitive, balanced ride — especially when carrying children or cargo. It’s quiet, efficient, and CE approved for UK road use.

Safety Meets Comfort
The bike is fitted with BENGAL hydraulic disc brakes front and rear, along with an integrated electric brake system. This cuts motor power the moment you brake, delivering safer, smoother stops while reducing the force needed on the brake handles.

The patented Anti-Tilt steering system helps the handlebars self-straighten after turning, offering increased confidence and balance – particularly helpful at low speeds or in tight spaces.
