How Many Kilometers for the Break-in Period of a Power-Assisted Bicycle?

Generally, the first oil change is at 500 kilometers, and the second at 1300 kilometers. Maintenance is crucial for power-assisted bicycles. Oil Change for Fuel-Powered Bicycles: The engine oil of fuel-powered bicycles must be changed regularly, with the interval adjusted based on driving conditions and vehicle status, usually determined by various factors. For new vehicles, due to the higher amount of metal shavings during the break-in period, the first maintenance must be done within three months (1000 kilometers), including changing the fuel and oil filter. Subsequently, depending on various working conditions, the fuel and oil filter should generally be replaced every 2000–3000 kilometers.
I've been riding motorcycles for years, and the break-in period for a new bike is no small matter. Typically, the initial period should be controlled between 500 to 1,000 kilometers. This distance allows the engine components to gradually wear in, reducing friction and avoiding premature wear. It's recommended to keep the speed below 60 km/h during this time, avoiding sudden acceleration or steep climbs to prevent excessive stress on the parts. When I first bought my bike, I didn't know better and took a long trip within the first 500 kilometers, which led to early engine noises and cost me thousands in repairs later. A properly broken-in bike will be more fuel-efficient, durable, and have a longer lifespan. Remember to regularly check the engine oil and chain tension; thinner oil is better for new bikes. In short, don't rush to speed—drive gently for the first few months. It's good for both the bike and the rider.
As someone who frequently repairs cars, I remind everyone to pay attention to the mileage issue during the break-in period of a new car. Most vehicles are designed with a break-in period of around 500-1,500 kilometers, during which new internal engine components need to run smoothly to reduce friction heat deformation. In practice, I've seen many cars suffer from cylinder scratches or a sudden increase in fuel consumption because the owners didn't break them in properly before driving at full load. It's recommended to limit the speed to 40-60 km/h for the first few hundred kilometers, avoid sudden braking and acceleration, and check the oil level once a week. Don't underestimate this—it directly affects the engine's lifespan. A well-broken-in new car means fewer repairs over ten years, saving both money and hassle. Also, pay attention to pre-warming the engine at startup—let the cold engine run slowly for a few minutes before accelerating.
