Components and Features


The Legion series usually come with U-brakes, which are known for their strong and dependable stopping power. These brakes are simple to take care of and give you good control over your bike, which is important for safety when you’re riding hard and pushing your limits.


Most Legion bikes have just one gear, which makes them easier to take care of and is pretty standard for BMX bikes. Having a single gear is ideal for BMX riding because it lets you speed up and slow down super fast, just like you need to.


The tires on the Mongoose Legion are designed for versatility. They offer a good grip on various surfaces, from concrete parks to dirt tracks. The tread pattern is designed to give you a good mix of speed and grip, so you can go fast and still feel in control.


Legion bikes aren’t built for mountain trails, so they don’t have fancy suspension systems like mountain bikes do. But don’t worry – they’ve still got you covered. The frame and fork have built-in shock absorbers that soak up small bumps and keep your ride smooth. This simple design also makes the bike lighter and easier to move around, which is perfect for BMX tricks and jumps.
