With the Legion Series, Mongoose offers a full line of freestyle BMX bikes for riders of all ages and ability levels. The Mongoose Legion L40 BMX Bike is a fully park, street or dirt-worthy freestyle BMX bike that offers everything a new rider could need to bust their first tricks on their local ramp! A combination of lightweight but strong parts means this BMX will stand up to a beating without breaking the bank.
3-PIECE CHROMOLY CRANK
The standard for high-end BMX bikes, 3-piece cranks are stiffer and stronger, meaning you can smash it at the skate park with confidence. Made with Chromoly, these cranks are lightweight while still retaining their strength.
HI-TEN STEEL FRAME, FORK AND BARS
Made with high-tensile steel, this is the perfect bike for those looking for something strong enough to take a beating without breaking the bank.
SEALED BEARING BOTTOM BRACKET
Sealed bearings in the bottom bracket offer reliability and reduced maintenance needs so you can focus on what matters, the riding!
What is this bike used for?
The Mongoose Legion L40 is a true all-round freestyle machine and is just as at home riding dirt jumps and pump tracks as it as on the street and in the skatepark.
How is this bike different?
This BMX utilises parts normally seen on much more expensive models to ensure it's strong, lightweight and tough enough to take a knock. It has geometry that suits all-round riders riding a variety of terrains.
Who is this BMX designed for?
The Legion is a perfect entry-level Freestyle BMX for riders who want a bike that won't break the bank, but is still extremely lightweight and durable. The top tube is 20.5 inches (521mm) and suggested rider height is 5’0” – 5’6”.
