About the MAPFOUR N1 AIR ST 250W E-Bike

The ENGWE N1 Air ST offers all the performance benefits of the standard model, but with a convenient step-through carbon-fibre frame for easier mounting and dismounting. This makes it an ideal choice for commuters, riders wearing everyday clothing, or anyone who prefers a more accessible frame style. It uses the same 250 W MIVICE motor with 40 Nm torque and features a removable Samsung battery capable of up to 100 km on a single charge — all fully compliant with UK e-bike regulations.

With a Shimano 7-speed drivetrain, torque-sensor assistance and mechanical disc brakes, the N1 Air ST delivers confident control and a smooth, natural ride. Its 700×38C tyres and lightweight frame make it easy to handle in busy urban spaces, while maintaining excellent comfort on longer routes. The step-through geometry ensures maximum convenience without compromising stability or performance, making it a versatile choice for riders of all levels.

The carbon-fibre construction further enhances riding comfort by absorbing road vibrations, while maintaining stiffness for efficient pedalling. Its modern design and user-friendly frame make the N1 Air ST especially popular with city riders looking for a dependable, stylish and easy-to-use e-bike that fits seamlessly into daily life.
