You may lose your license. It is illegal to ride a drunk bike, with the fine two penalty units – $100. They receive the same penalties as when they drive a car – they do not play with up to a year in prison and 30 penalty points for a first offense; doubled if you get caught again. As you can see, when someone says that e-bikes are illegal in Australia, they obviously don`t know what they are talking about and have just made their decision based on myths. Washington State has no laws specific to motorized bicycles. Since mopeds are by definition the closest vehicle, it is best to be safe and refer to moped laws so as not to accidentally break the law. Current laws in some states/territories allow the use of motorized internal combustion bicycles, as long as they do not produce more than a certain number of watts of power. In Tasmania and the Northern Territory, this limit is 200 watts. Queensland, New South Wales and South Australia have banned the use of ICE motor bikes.
For example: «In New South Wales, all petrol bikes are prohibited on New South Wales roads and in road-related areas such as walking trails, shared trails, cycle paths and cycle paths. The ban, introduced on October 1, 2014, covers bicycles that: More and more designers of motorized ICE bicycles and other small-engine off-road vehicles are turning to four-stroke gasoline engines that consume less fuel and oil and tend to be quieter while producing fewer emissions.  Honda 49 cc GXH-50, Shandong HuaSheng 49 cc 142F, Robin/Subaru 25 cc and other small four-stroke engines are commonly used as part of an engine-transmission combination to fit a variety of bike frames. According to Russian law, no one under the age of 16 is allowed to ride a gasoline-powered bicycle (defined as a moped with a gasoline engine below 50 сс) with a maximum speed of 50 kilometers per hour (31 mph)). The moped rider must wear a helmet and respect the correct limit. Bicycle motors are not registered. Since 2014, the moped driver must hold a category «M» driving licence or a higher diploma. But as of 2015, there is no official procedure for obtaining the «M» license, so moped riders are still not under control in practice. The first motorized bikes were ordinary service bikes equipped with an additional motor and gearbox to support the normal pedal drive, and it is this form that distinguishes the motorized bike mainly from a moped or motorcycle. At a time when gasoline and transmission engine designs were still in their infancy and the power-to-weight ratio was low, a dual-use propulsion system seemed particularly beneficial. Over time, pedal drive has been increasingly replaced by the constant use of a two- or four-stroke gasoline engine.
Nevertheless, the concept of using an engine mount for the ordinary bike has proven its worth, and the concept has resurfaced regularly over the years, especially in times of austerity measures or fuel shortages. In countries where cars and/or fuels are prohibitive, the motorized bicycle continues to enjoy great popularity as the main means of transportation.  In Greece, bicycles supported by an electric motor up to 0.25 kW are clearly allowed by the Highway Code and are still considered normal bicycles. Therefore, all laws for bicycles also apply to electric bikes. No license is required to drive them. In Belgium, the Minerva company, later known for its luxury cars, began manufacturing standard safety bikes in 1897 before expanding into light cars and «motorcycles» from 1900. They produced lightweight clip-on motors mounted under the front tube, specifically for Minerva bikes, but also in kit form suitable for almost any bike. The motor drove a belt that rotated a large gear that was attached to the opposite side of the rear wheel like a chain. Until 1901, the kit engine was a 211 cc unit with 1.5 hp that ran comfortably at 30 km/h (19 mph) at 1,500 rpm, reached a top speed of 50 km/h (31 mph) and achieved fuel consumption of the order of 3 L/100 km (94 mpg-imp; 78 mpg-US). These kits were exported worldwide to countries such as the United Kingdom, France, Germany, the Netherlands, Australia and other British territories of the time.  The pedals of a motorized bike must be the main source of energy, with the motor providing only support. Regardless of the power of the motor, the electric motor, if it is the main source of energy, is illegal and cannot be driven on roads or paths.
For example, if you can turn a throttle and finish a ride with only the power of the bike`s motor without using the pedals, it`s illegal. Individuals have built bicycles powered by steam and air engines, and there are many well-known jet bikes. There is no known large-scale production of these (although the jet bikes were developed by hobbyists, as seen in some homemade videos on sites like Google Video and YouTube). In Canada, eight provinces currently allow the operation of low-power electric motor bicycles that reach a maximum speed of 32 km/h as defined as electric bikes. The Province of Ontario launched a three-year trial that ended in October 2009 for these bikes, which are now officially defined by the Ontario Ministry of Transportation as electric bikes with certain parameters.  In Japan, only the following exceptional electric vehicles are considered normal bicycles or pedestrians in the law. Cycling for all ages on hiking trails is legal in Western Australia. Anyone can ride a bike on a trail, but there are a few conditions. For more information, visit the Road Safety Commission website.
In the 1930s, the United Kingdom and its former colonies also developed «clip-on» engines for bicycles (35 to 49 cc), followed by the «Autocycle» with a custom frame with pedals and a two-stroke engine (often a 98 cc Villiers engine), but without a gearbox (e.g. Malvern Star). Motorcycle manufacturers were well established in countries like the United Kingdom and Australia before World War II. The legal status of a motorized ICE bike in the United States is currently determined by the laws of each state and/or local jurisdiction. Several states allow the use of ICE motorcycles on roads without registration, taxes or permits in the same way as bicycles, provided certain restrictions are respected.  Many jurisdictions use maximum speed and/or engine displacement limits to determine whether motorized internal combustion bicycles require registration and licensing – sometimes as mopeds, sometimes as motorcycles.  Some states prohibit the use of motorcycles on multi-use recreational trails or limited-access high-speed roads, while others require additional safety equipment to travel on public roads, such as wearing a helmet.  Many cities in the United States and other local jurisdictions may impose additional restrictions on motorized ICE bikes when operating on public roads. Rules and regulations for bicycles, including e-bikes, can be found on the Websites of the Road Safety Commission for Cycling. In 2003, the production of the French gasoline VELOSOLEX in Hungary was stopped. However, production in China will continue and resume in France. In the United States, Velosolex America distributes VELOSOLEX worldwide.
In South Australia, there are 2 categories of servo bikes that are legally allowed to be used on our roads. In 1896, E. R. Thomas of Buffalo, New York, began selling gasoline engine sets to power ordinary bicycles. After founding the Thomas Motor Company, he began selling full motorized bicycles under the name Auto-Bi. The Auto-Bi is widely regarded as the first motorized production bike to be manufactured in the United States.  Vehicles that are not considered bicycles are wheelchairs, recreational equipment on wheels such as Segways, toys on wheels such as scooters, skateboards or skates, or any vehicle with an auxiliary motor that can generate more than 250 watts of power (whether the engine is running or not). In the 1960s, moped madness arrived in the United States, Britain and other countries. Mopeds were produced for years in France and Italy, but were largely unknown in other countries. The increase in the popularity of the moped was motivated by the arrival of new machines made in Japan by Honda, Yamaha and other manufacturers that could be used without a driver`s license and with minimal effort to comply with existing regulations of the authorities. The new models of mopeds were low-power motorcycles equipped with pedals to meet legal requirements.
Most of them were difficult to pedal for short distances on flat ground. Ultimately, an electric bike can save you tons of money. It may be that the acquisition cost is slightly higher than normal compared to conventional bikes, but even that is not a sure thing. In addition to the initial purchase, electric bikes are also relatively inexpensive to maintain, especially compared to automobiles and motorcycles. -Powered by any type of internal combustion engine.  All state legislation favors electrically assisted bicycles over internal combustion engine bikes.
