I think every boy should have a bike. They love the feeling of freedom and opportunity to go places on it. So that's why I have a view on Boy Mongoose Montane Mountain Bike 24-inch wheels. Boys will be boys, and a bicycle for nine years must have certain qualities if it is going to survive!
I do not know about you, but I raised two boys and can destroy everything in site! So if you're considering a bike for nine or ten year old boy, you get one that will be able to stand abuse that will come in the way. Later, when the older and more responsible, it will be time to buy him his dream bike.
On the other hand, you do not want to buy complete garbage and say, oh well, when it breaks I'll just buy a new one. He at least understood that he must be careful with it. The ideal is somewhere between a cheap boxed type can be obtained at discount stores and "real McCoy" came in specialist shops.
This is where this bike comes in. It's good quality gear, so he can learn to use them properly, which is very important for his future enjoyment of sport. If you enjoy biking himself, he will be able to go on a ride with you and when it is ready you can get him the best.
Another thing that is important to bear in mind that it will become a bike within two years or so. So, spending a fortune on it is really not a good idea. So, if you my personal opinion, look at the Boy Mongoose Montane Mountain Bike 24-inch wheels is well worth a look.
