How fast can the Koolux X7 Electric Bike go?

Top speed depends on the model and setup. Real-world speed varies with rider weight, terrain, battery level and which speed/assist mode you’re using.

Is the Koolux X7 Electric Bike road legal in the UK?

Many e-bikes are supplied with a UK-compliant assist setting (25 km/h / 15.5 mph). If you use higher-speed or higher-power modes on public roads, it may be treated as a motor vehicle and need registration, tax and insurance. Always ride to the current rules.
