The height of the handlebars on a mountain bike should be determined by the rider’s comfort, riding style, and the type of terrain they plan on riding. Generally, the handlebars should be positioned in a way that allows the rider to maintain an upright position, with their hands resting comfortably on the bars and their elbows slightly bent. It is important to find the right balance between comfort and control, to ensure a safe and enjoyable ride.

It depends on the type of mountain bike and its intended use. Generally speaking, 15kg is considered heavy for a competitive cross-country mountain bike but may be acceptable for a trail or enduro bike that prioritizes durability and stability. The weight may also be influenced by the materials used in the bike’s construction. Ultimately, the weight of a mountain bike should be comfortable for the rider and suit their personal requirements and skill level.

To lift your front wheel on a mountain bike, you need to shift your weight back by crouching down and then rapidly pulling up on the handlebars while simultaneously pushing down on the pedals in a quick jumping motion. This will help you lift your front wheel off the ground. Practice this technique by starting slow and gradually increasing your speed. Use this technique to lift your front wheel when going over obstacles or challenging terrain.
