I love mountain biking I usually mountain bike on the weekend's my favorite weather is when it is hot and dust so you can slip on a log or something. I have a trek it is a bike brand. I love biking with my friends because it is fun to have someone around if you lets just say break you leg. The best trick I have done off a jump is a no footer. That is when you go off the jump and take your feet of the pedals. I like road biking to because of the speed one time my friend and my dad road 2 miles without go lower than 23 miles per hour (MPH). Also if you get a bike I would recommend a trek.
I hope you try mountain biking because it gives you good exercise and it is fun.
