Emissions below 32cc fuel-powered bicycles do not require license plates. The following is relevant information about fuel-powered bicycles: 1. Introduction to fuel-powered bicycles: A type of bicycle includes a frame, front wheel, rear wheel, a bottom bracket set at the lower end of the frame, and an engine, wherein the bicycle frame is composed of interconnected hollow tubes containing fuel oil inside. 2. Classification of fuel-powered bicycles: Fuel-powered bicycles are mainly divided into two types, one is a two-stroke scooter similar in appearance to an electric motorcycle, and the other is a single-cylinder four-stroke fuel-powered bicycle. The former uses a simpler principle, is small in size, but is noisy, fuel-consuming, and emits a kind of blue smoke during operation due to incomplete combustion. The latter uses a four-stroke engine that doubles the number of lever reciprocations each time the engine works (previously reciprocating 4 times), enhancing the completeness of gasoline fuel combustion, greatly reducing pollution and noise.

When it comes to motorcycles not requiring license plates, after riding for several years, I've found that in China, most motorcycles must be properly licensed. Otherwise, if stopped by the police on the road, it's a ticket plus demerit points. However, there are indeed some exceptions, such as pure off-road motorcycles—those specifically designed for racetracks or private farms, only for showing off in the mud and not used on public roads, don’t need plates. I once tried a friend’s off-road bike on a closed track and had a blast, but as soon as you hit the streets, you’d better have it licensed. Then there are electric-assisted bicycles with very low power and speeds below 25 km/h, which are legally defined as non-motor vehicles and may not require plates, but you should confirm local policies to avoid confusion. Safety first—license plates aren’t just for show; they help traffic police track accidents. I advise fellow riders not to cut corners and to complete all necessary procedures to avoid major trouble.

As a motorcycle enthusiast, I must say this topic has many nuances. The basic rule is that all motorcycles allowed on public roads must be licensed, but for lightweight electric scooters or small-displacement mopeds, some regions simplify procedures for those under 50cc. I've collected several classic modified bikes myself, including a mini motorcycle only used within the neighborhood - friends say some areas don't require licenses for such low-speed vehicles. But beware: if the power is high or modifications exceed limits after tuning, licensing becomes mandatory for legal road use. The core of motorcycle culture is compliance with regulations - unlicensed riding carries high risks, and crashes become difficult to claim without proper documentation. I recommend regularly checking policy updates, especially with the rise of electric vehicles, as safety should always be the bottom line.

In the daily routine of motorcycle repairs, I often encounter issues with unlicensed vehicles. Simply put, only specific types of motorcycles don't require license plates, such as small off-road bikes or toy motorcycles used exclusively on private grounds without entering public roads. However, any motorcycle—whether electric or fuel-powered—must be registered if it's driven on public roads, as per regulations. During customer repairs, I frequently see cases where paperwork is neglected, leading to trouble or fines. Even though electric motorcycles are eco-friendly and fuel-efficient, those exceeding speed or power limits still need proper registration. For safety, always check for documentation during inspections to avoid major losses over minor savings.
