This is obviously not Merida. So careless and didn’t read the trademark! ? There is a trademark in the third photo, with "MELDA" in white letters. I have never heard of it. Merida is MERIDA! (This is the case with all the side-stepping of famous brands, with similar names, such as the "Kang Shuai Fu" instant noodles incident. I guess you don't know about it, so hurry up and make up for it. "Jia Mao Wei Lie" is a trap for people like you). In addition, people with a little basic knowledge of bicycles will also find that the parts in the photos are also missing - for example, the cranks are so thin and have bumps on the surface. They are not made by a major manufacturer. Merida's, even a floor-level car priced at RMB 1,000, is manufactured by Haomeng, a large manufacturer. It is thick and has a smooth surface and sufficient hardness (it will not deform when it is crashed or bumped) (go to the MERIDA store to see all the cars for sale) How much does it cost? The workmanship and size of the crank are obviously better than this one). The rear derailleur in the third picture is "UNAGSAI", a brand I have never heard of. Even though Merida's gears cost 1,000 yuan, they are still brand-name Shimano. As for other-brand gearshifts, they are often inaccurate, have problems, make noise, etc. . . If you buy this car for the sake of bargain, it is recommended to go to a big brand car shop (such as Giant, Merida or Xide Sheng) and let the technician do a major inspection. Cheap cars from other brands may have safety hazards, such as screws that are not tightened in place or are not tightened properly. If it is too tight, etc., and if a novice does not understand care and maintenance, using it for a long time may endanger his own safety.
MERIDA: The letters "MERIDA" are printed on the frame; depending on the grade, year, and model, the color and pattern of the letters are different, but they are all MERIDA with a tilted feature. Some brands are "Merida" in Chinese, which is also fake, because MERIDA has only one registered Chinese name, "Merida", but the Chinese characters are not used on the frame.
The more common cranksets and cranks on Merida mountain bikes are Shimano (SHIMANO, all Shimano accessories will be printed with the "SHIMANO" trademark). This is a low-end crank from SHIMANO, but please compare it with the crank in your first photo.
The rear derailleur used by Merida (the cantilever suspension red wheel structural accessory in your third photo is the rear derailleur) is also Shimano. Note that it is also printed with SHIMANO.
