Mountain bike is the best choice for beginners. Because mountain bikes have very low requirements on the ground, they can ride on any ground, and it is not easy to have a flat tire.
The frame of mountain bike is rougher, stronger and has better shock absorption performance. Generally, there are front forks and some rear ones, so the seat is wider and the ride comfort is higher. Generally, a wider straight handle is used for better handling, but when riding, the resistance is greater and the speed is slower.
Road cars are more suitable for experts than novices. Because the road car has very high requirements on the road surface, it is possible that the tire of the road car will burst after only a few gravel, and if the road surface is too slippery, the road car is more prone to deviation than the mountain bike, and the novice may not be able to control such a car.
