Let’s take straddle bikes as an example. The most common one is chain drive. A few domestic cruisers and Harley-Davidson use belt drive . Let's take a look at the advantages and disadvantages of these two transmission methods.
The chain drive can be used for more direct maintenance and the power transmission can be more quickly and easily. Kilometers. But the biggest advantage is actually cheap and wide applicability. After driving for a certain number of kilometers, some riders directly replace the chain without even having to do maintenance.
There are many shortcomings, first of all, maintenance is troublesome. Because it is exposed, a thick layer of dirt sludge will accumulate every 2.3 thousand kilometers. If it is not cleaned in time, the life of the chain will be affected, and the driving sound will become louder, resulting in a decrease in driving texture. Failure to maintain may result in the risk of corrosion, which will affect driving safety.
How to maintain is also a troublesome thing. First of all, ordinary cleaning agents can’t dissolve the sludge very well. You need to buy a motorcycle chain cleaning agent. A bottle is about 30 yuan. It can be used twice. If you want to clean it easily, you have to buy it. It takes more than 100 yuan to set up a frame.
After you have finally washed the chain, you have to apply special chain oil or chain wax. Of course, you can also use waste oil , but...waste oil It is easy to get dust and oil,The duration is short, so many agricultural models generally add a chain cover, which can greatly reduce the dirt attack!

In addition, the chain will be stretched and loosened after being used for a certain number of kilometers. The chain needs to be tightened in time, otherwise the chain shakes too much and there is a risk of breakage. The number of kilometers for maintenance varies according to personal use. For the Buddha, you may drive 4.5 thousand kilometers every time; if you drive too hard, you may have to tighten the chain for 2,000 kilometers.
Of course, if the oil seal chain is used, the above maintenance period can be greatly extended, but the oil seal chain is not equipped for ordinary models, and the price is not cheap, a better oil seal chain At least 300 or more.

Belt drive
Belt drive
is generally more common on pedal and cruising vehicles. There are many advantages. First of all, it is easier to avoid dust, no need to tighten the chain, almost no maintenance, low vibration noise, and good smoothness.
The disadvantage is: high cost, currently there are two brands of Continental and Gates on the market, the price of a belt is close to 2,000 yuan; in addition, the transmission efficiency is not as good as the chain, which resists overload Poor capacity, so the applicability of belt drive is not good.

Summary: The chain is cheap and has wide applicability.But maintenance is troublesome; the belt is quiet and hassle-free maintenance but expensive. Both methods have their own advantages and disadvantages. How to choose depends on personal preference and budget.
