⚠️ Dubble eBikes are set up to comply with NSW electric bike regulations, with a continuous rated power of 500W and a top assisted speed of 25 km/h. This qualifies them for use on public roads, shared paths, and bike lanes under EPAC (Electrically Power Assisted Cycle) rules.
Each bike includes a throttle isolator switch, which is off by default when first powered on. Throttle use is for private property only and must remain disabled in public.
Speed unlock options, if available, are intended only for off-road or private use. Public use of the bike outside its legal configuration is not permitted and may impact insurance or legal liability.
Electric bike laws differ by state. In some areas, only 250W continuous output is allowed. It’s your responsibility to ensure your use complies with local road laws.
For more information, refer to our FAQ and Terms of Service.
