1, play with the ladder-the frame of Merida 500.600 may be a bit too much, unless you only have 100 kg. But the shelves of Merida at this price are stronger and heavier than those of Giant. So from this point of view, Merida, as for 500.600, buy that one if it looks good.

2. Go out to play on weekends-of course, a lighter car has an advantage. 500.600 is almost enough. Giants are relatively light, but personal feelings have little to do with it. Personal physical strength is the decisive factor.

3, rotten road-if there is mud or something, the disc brake is still a little useful. 600 is better than 500. I don't know how strong it is ... another important point is the front fork. At this time, the damping function of the front fork can not be ignored. But 500.600 half a catty is not generally hard, and it feels quite uncomfortable when the road is a little steep. In contrast, the giant fork at this price is slightly stronger.

4, the slope is small-the disc brake is safer and it is not easy to lock the tire.

Generally speaking, from the performance point of view: 600, after all, it is still worse than 400 yuan, which has his reasons. To say the least, even if his advantage is not 400 yuan, but 300 yuan, then more 100 is equivalent to buying an experience. As an attempt, he also has a good relationship with the store, so that he can buy things in the future. From the financial point of view: if money is tight, you can forget about 500 yuan, because the money saved can buy some better equipment, helmets are necessary, and there are many things.
