Haojue chooses chain drive. Here are the relevant details: Chain drive predominates: Haojue 150 models equipped with pushrod engines are likely quite rare, and currently none are available. Haojue models primarily feature chain-driven engines. Advantages: The main benefits of chain drive lie in smoother operation with minimal vibration, fluid acceleration, and higher top speeds. In contrast, pushrod engines excel in strong burst power, simple structure, and easy , but their significant drawback is excessive vibration which reduces user experience and riding comfort. Haojue's extensive use of chain-driven engines prioritizes stable performance and reduced vibration, making chain drive the preferable choice for vehicles ridden on flat terrain.

As a Haojue owner, I commute daily. The chain-driven engine is fast, quiet, and smooth, but is annoying—the chain keeps needing adjustment. The pushrod engine is simple and reliable, great for city riding. The pushrod engine has quick starts, while the chain-driven engine is smoother at high speeds. Choose based on your riding style. Haojue has good quality, and with proper maintenance, it can last long.

Chain engine enthusiasts prefer overhead engines for their lighter weight and lower maintenance, while overhead valve engines are favored for their simplicity and ease of upkeep. The Haojue chain engine is great for high-speed riding, while overhead valve engines are more suited for everyday commuting.

Beginners find overhead valve engines easy to use but chain difficult, with low oil consumption.

The chain mechanism with top rods is cost-effective for riding Haojue, with a low total cost.

Old-school pushrods are more durable than chain-driven engines, as chains are prone to breakage and pushrods last longer.
