👋 Hello, Welcome to Electrified Motors UK. We offer high-quality electric conversion kits for bikes with rear dropouts of ≥135 mm and HG cassette drivetrains (1–11 speed). This 250W kit is compact yet powerful for its class. ⚡ (Actual performance depends on rider weight, terrain, and weather.) Typical performance (private land): ~20–25 mph top speed (depends on rider weight/terrain) and ~15–30 miles per charge. For more torque and higher top speed, use a 48V or 54V battery. UK public roads: Street Mode limits assist to 15.5 mph (25 km/h) with pedal assist only.
