Mountain wheel diameter is generally 26 inches, the limit wheel diameter is slightly smaller than 24 inches. If you are daily cycling, should choose 26 inch mountain bike is more suitable, this size is the most common, accessories are easy to obtain, cycling efficiency is higher. 24 inch except for show cars, generally only suitable for teenagers transition size.
