How to Master the Art of Stoppie on a Mountain Bike
To do a stoppie on a mountain bike, shift your weight forward by leaning over the handlebars as you apply the front brake. Keep your feet level and off the pedals. As the bike comes to a stop, use your body weight to lift the rear wheel off the ground. Balance as long as possible before lowering the back wheel back down. Practice in a safe, empty area before trying on trails or roads with other people.
