What are the advantages of the rear single shock compared to the traditional rear double shock absorber

The double shock absorber will cause instability of the frame due to wear and tear of the drops after use, spring fatigue return inconsistency, damping difference and other factors, and the cost is too high to achieve. Single shock absorbers do not produce the above factors, so double shock absorbers are mostly used in low-speed cars, and single shock absorbers are used in high-speed cars or sporty cars.

With the use of rear monoshock, the car's maneuverability and sense of traction is strong, anyway, there are a lot of benefits, but there are also disadvantages, related to money.

Summarizing, using a rear monoshock is good for maneuverability and traction, but there is a prerequisite that the fork must be strong, otherwise it's not as good as a monoshock. There have been cases where the fork was bent due to the lack of strength of the single reduction, forcing the buyer to strengthen the fork themselves.
