You enjoy mountain biking and want your children to enjoy it as well. There’s nothing like ripping some singletrack with your favourite small person or seeing their face light up when they reach the bottom of a tough drop to make you grin.
The performance of your child’s bike is one of the most important elements in how much fun they will have mountain biking. It doesn’t have to be the most expensive or fanciest mountain bike to be enjoyable, but it does have to be lightweight, fit properly, and perform effectively.
In terms of how well a bike would function for a youngster, weight, in particular, is a major distinction. Many children’s mountain bikes are HEAVY; in fact, they’re probably heavier than your mountain bike.
And because your children are much lighter than you, the bike-to-body-weight ratio is wrong. If your child is riding a heavy kids mountain bike, he or she may become exhausted soon, frustrated easily, and may abandon the sport altogether.
