They are not sold as street-legal vehicles. Riding laws for electric dirt bikes vary significantly by country, state and municipality — it is the rider's responsibility to confirm local requirements before riding. See [Riding Laws & Compliance](https://wiki.cemotoride.com/link/381). Electric bikes (commuter, mountain and fat-tire models) are designed for on-road and improved-trail use. Always wear an approved helmet, and read the owner manual for your specific model before your first ride. --- ## Notes on this documentation **Language.** All customer-facing content in this documentation center is written in English. **Performance figures.** Top speed, range and charge-time figures quoted throughout are manufacturer-stated maximums under controlled test conditions (typically a 70 kg rider, 25 °C ambient temperature and 20 km/h constant speed for range tests). They are **not simultaneous guarantees**. Actual performance varies with rider weight, terrain, temperature, tire pressure, battery condition and riding style. **Specification changes.** CEMOTO continuously improves its products. Specifications and manual content are subject to change without notice. Where an illustration or specification in a manual differs from the physical product, the physical product governs. **Source of truth.** Where this documentation and an official published policy differ, the policy currently published on cemotoride.com governs.
