How about Hummer mountain bike?

Let's just say that all Hummer bicycles on the market are assembled in Shenzhen from the main parts imported from American General Motors and then sent to all parts of the country. What foreign imports you see, what Montessori stragglers are all fake, and nothing is purely imported from the United States. Of course, you can buy genuine products in major specialty stores, and the body has the unified code of General Motors. The specifications are roughly the same as those of the military. Of course, they are definitely not military specifications. You can't buy military ones in America. Of course, your relationship with the US military is another matter. You won't fall apart if you buy genuine products. Hummer bicycles are very strong, and the quality is absolutely guaranteed. Other famous mountain bike brands are: Specialized, BMC, Huffy, Marin, etc. Of course, they are all expensive. If you really can't, buy domestic ones, such as: permanent, giant, flying pigeon, phoenix and so on. Especially if your driving environment is not particularly harsh, just buy an ordinary folding lightweight bicycle for comfort, because more professional bicycles give priority to comfort for performance, such as hard seats and heavy mountain bikes for off-road and firmness.
