The Mountain Bike exists in the game as one of only three bicycles in GTA San Andreas, designed more for speed and power rather than nimbleness and ability to execute bicycle tricks. Indeed, the Mountain Bike is the most capable in hill climbing; even if an incline is significantly steep, due to the fact that it has multiple gears (while other bikes only have one). The player can tap the acceleration command while on a Mountain Bike can climb its slope with less effort than other bicycles. As mentioned, the Mountain Bike is less tailored for stunting, and only allows the player to execute moderately high bunny hops when the player can hop higher on a BMX.
- In most cases, the Mountain Bike is available parked in specific locations in State of San Andreas:
- On top and at the base of Mount Chiliad. The bike on the summit starts The Chiliad Challenge, and the bike is used in challenges 1 to 3.
- The parking lot outside the Creek Safehouse in Creek, Las Venturas.
- Beside one of the buildings next to the waters in Esplanade East, San Fierro.
- In the motel where you can find the Blueberry Safehouse, beside the wall in Blueberry, Red County.
- Near house uphill from El Quebrados, Tierra Robada.
- In an open garage in Palomino Creek.
- Because of its implied off-road capabilities, the Mountain Bike is more commonly found ridden by leisure bikers in forested or hilly rural areas, including northern Whetstone (particularly around Mount Chiliad) and Missionary Hill.
- There is one hidden in Back O Beyond.
Grand Theft Auto VThe Mountain Bike returns in GTA V. It seems larger than GTA: San Andreas version. It's also featuring fenders now.
- The Mountain Bike has a glitch that only works in the original PlayStation 2 version of Grand Theft Auto: San Andreas. While reversing, rapidly tap the accelerate button (normally X), and CJ's body will twist ridiculously out of proportion.
