What kind of fuel should a power-assisted bicycle use?
4 Answers
Power-assisted bicycles use 93-octane gasoline. A full tank can typically cover about 150 kilometers, with slight variations depending on driving habits and road conditions. According to the national standard GB17284-1998 for gasoline-powered bicycles, a gasoline-powered bicycle refers to a special type of bicycle equipped with a gasoline engine, two wheels, and capable of both pedal and motorized functions. Introduction to fuel-powered bicycles: A fuel-powered bicycle includes a frame, front wheel, rear wheel, a bottom bracket at the lower end of the frame, and an engine. The frame of the bicycle is composed of interconnected hollow tubes containing fuel oil. The top front and rear of the frame are equipped with a fuel filler hole and an air vent, respectively, and an oil pipe connects the lower part of the frame to the engine. The utility model of the power-assisted bicycle is simple in structure, compact in size, lightweight, safe, reliable, and aesthetically pleasing. Reference standards for fuel-powered bicycles: In the "Traffic Law," there are clear regulations classifying electric power-assisted bicycles as non-motor vehicles; however, there are no explicit regulations for fuel-powered bicycles. According to the "Technical Specifications for Motor Vehicle Safety (GB7258-2004)," fuel-powered bicycles should be classified as light motorcycles.
I used to ride a gasoline-powered moped that ran on 92-octane fuel, but it's best to check the manual for confirmation. Some older two-stroke models require mixed oil, typically at a 20:1 ratio – using the wrong mixture can cause engine seizure. My neighbor's moped got scrapped because of incorrect oil mixing, and the mechanic mentioned that modern four-stroke engines generally don't need premixed fuel, just unleaded gasoline. Always turn off the engine and stay away from open flames when refueling, and avoid filling the tank completely to allow for expansion. In winter, adding antifreeze can prevent fuel line freezing, though this isn't necessary in southern regions.
In our student days, we often used mopeds for transportation, mostly filling them with 92-octane gasoline. Nowadays, new cars can also use 95-octane, but it's a bit more expensive. For engine oil, it's recommended to buy specialized small bottles; the motorcycle-specific oil sold at gas stations works fine. Once, I forgot to add oil and rode for half a month, causing the engine to squeak. Later, I spent over 200 yuan at the repair shop to fix it. The refueling cycle depends on usage frequency. If I ride 10 kilometers daily, I refuel every two weeks and change the engine oil once a month. Don't be tempted to use cheap, low-quality fuel, as it can easily cause carbon buildup in the engine.
With over a decade of motorcycle repair experience, fueling mopeds is straightforward: use a 25:1 gasoline-oil mixture for two-stroke engines, while four-stroke engines can directly use 92-octane gasoline. Choose motorcycle-specific SL-grade oil, opting for higher viscosity in summer. A common mistake is using car engine oil or diesel, which causes premature piston ring wear. Once, a customer mistakenly added diesel to their moped, completely clogging the carburetor and costing over 300 yuan to clean. Always pay attention to fuel grade and avoid filling up at small, unreliable stations—low-quality fuel with impurities can clog the fuel system.
