Downhill mountain biking is a type of bike riding where you go down a steep and bumpy hill.
First, you need a special bike that has big tires with lots of tread, a suspension that helps absorb bumps, and strong brakes. Some bikes also have extra gears to help you pedal up the hill before you go down.
When you start, you wear a special helmet and other protective gear like pads on your elbows and knees. You stand up on the pedals and hold on tight to the handlebars.
Then, you pedal hard to gain speed and go down the hill. It can be really fast, and there are lots of obstacles like rocks, roots or jumps that you need to go over or around.
You also need to keep your balance and steer the bike in the right direction. The faster you go, the more wind you feel in your face and it can be a little bit scary, but also super fun.
At the end of the trail, there is often a big jump or a ramp that you can ride off of to fly through the air and do tricks like jumps or spins.
Overall, downhill mountain biking is a thrilling and exciting sport that requires skill, courage, and lots of practice. It's a great way to enjoy nature and get some exercise while having a blast at the same time.
