Mongoose Legion Intermediate
When the bike arrived at my doorstep, I was eager to get my hands on it. The packaging was solid, and I could immediately tell this wasn’t a run-of-the-mill BMX bike. It shipped with a straightforward assembly process that didn’t take too much time or effort. Inside the box, the bike came neatly packed, ensuring that no parts were damaged during transport.
Quality Build and Design
Upon seeing the Mongoose Legion L20, I was impressed by its sleek black design, complemented by the sturdy Hi-Ten steel frame. The design is unmistakably BMX, with a focus on strength and durability, but with a modern touch. The frame feels solid and substantial, which is a crucial factor when you’re out performing tricks or riding over rough surfaces.
What sets this bike apart from others I’ve ridden is the meticulous attention to detail. The frame material, Hi-Ten steel, strikes the perfect balance between strength and weight, offering durability without feeling too heavy. The bike’s build inspires confidence, which is key when you’re looking to tackle any BMX challenge.
Performance
The Legion Intermediate excels in performance with its strong drivetrain, responsive crankset, durable wheelset, reliable braking system, and precise steering. Whether you’re cruising, performing tricks, or tackling off-road trails, this bike offers smooth and controlled rides for any freestyle BMX rider.
Drivetrain and Crankset
One of the highlights of the Mongoose Legion Intermediate is its drivetrain. Equipped with a 25x9T gearing, the bike delivers a seamless riding experience, whether you’re cruising the streets or executing intricate tricks. The one-piece forged steel cranks are strong enough to handle the abuse of freestyle riding while still feeling responsive.
The 170mm cranks provide ample leverage, allowing for smooth pedaling even during high-intensity rides. I found the power transfer to be excellent—each pedal stroke felt effective, and I didn’t notice any slippage or delay. Whether performing a quick burst of speed or riding casually, the drivetrain delivers exactly what you need.
Wheelset and Tires
The 20” x 2.3” tires mounted on aluminum single-wall 36H rims provided a great balance of grip and durability. I noticed that the tires offered solid traction on both flat ground and when riding on dirt trails. This was particularly useful when I took it out for a few off-road sessions; the wheels held up well even on uneven surfaces.
The wheels are sturdy, but not too heavy, which means the bike doesn’t feel sluggish when performing tricks like bunny hops or slides. The front hub is equipped with a 3/8” female axle, while the rear hub comes with a 9T cog sealed bearing cassette, which ensures smooth operation without any unnecessary friction.
Braking Power: Single Rear U-Brake
For someone like me who’s always experimenting with speed and trickery, a reliable brake system is a must-have. The Legion Intermediate comes with a single rear aluminum U-brake that provides excellent speed control. While you might think that a single rear brake might not be enough, I found it more than adequate for freestyle riding. Whether I was doing tricks in the park or navigating tight corners, the brake gave me precise control over my speed.
The brake levers are made of lightweight aluminum, ensuring that I could adjust the pressure easily without tiring my fingers. As an intermediate rider, having a brake system that offers reliable stopping power is important, especially as I get bolder with my stunts.
Handlebars and Fork: Precision Steering
The handlebars of the Mongoose Legion L20 are an absolute game-changer. The 8” Hi-Ten steel rise handlebars provide excellent control while keeping you upright during those high-flying moments. They feel strong and stable, ensuring you maintain balance no matter how aggressive the trick is.
What really sets the bike apart, though, is the fork. The Hi-Ten steel BMX fork with a 1-1/8″ threadless steerer and taper legs provides excellent handling. The tapered leg design is not only visually appealing, but it also contributes to better control and stability, especially during fast turns or landings. The 50mm stem adds another layer of stability, giving you the confidence to tackle obstacles with ease.
Comfort and Handling
Riding the Legion Intermediate for extended periods didn’t leave me sore or uncomfortable. The ergonomics are well thought out, with the bike’s geometry designed to offer comfort even on longer rides. The 50mm stem and 8” rise handlebars ensure that I can ride without straining my back, and the rigid suspension is ideal for smooth control during freestyle maneuvers.
I also appreciate the weight of the bike. Weighing in at around 34.4 pounds, it strikes a great balance between being sturdy enough for tricks and light enough for quick maneuvers. I’ve used bikes in the past that were too heavy to perform certain tricks, but the Mongoose Legion L20 feels like the perfect weight to execute everything from wheelies to grinds.
Built to Last
The Mongoose Legion L20 is built to withstand the wear and tear of BMX riding. I’ve taken this bike on numerous street and park sessions, and after a couple of months of use, it still feels like it just came out of the box. The Hi-Ten steel frame has shown no signs of damage or wear, and the wheels remain true despite some rough treatment.
The removable brake mounts are another feature that adds to the bike’s long-term durability. They allow for customization and adjustments, giving you more flexibility as you improve your skills. Additionally, the aluminum single-wall rims and sealed bearings in the hubs have held up without any issues.
Assembly and Setup
If you’re new to BMX bikes, you may appreciate that the Mongoose Legion L20 ships with a simple assembly process. While it doesn’t come pre-assembled, the instructions are clear, and all the necessary tools are included in the package. I was able to get it ready to ride in under 30 minutes without needing additional help, which is a huge plus for anyone looking to get started quickly.
Warranty
Another great thing about the Mongoose Legion L20 is the warranty. The frame comes with a 5-year limited warranty, while the parts are covered for a year. This added security ensures that I can enjoy my bike without constantly worrying about it breaking down after extensive use. It’s also nice to know that Mongoose stands behind their product with such an extensive warranty.

If you’re looking to buy the Mongoose Legion L20 BMX bike, you’re likely interested in a bike that offers performance, durability, and versatility for freestyle riding. Whether you’re an intermediate rider or a beginner aiming to grow, here are some factors to consider before making your purchase.
Rider Height and Age
Before you make a purchase, ensure that the Legion Intermediate is the right size for the rider. This bike is designed for riders between 4’8″ and 5’4″ in height, which typically corresponds to older children or teens.

The bike’s tires are perfect for street riding, but they’re not built for extreme off-road terrain.
Durability and Materials
The Hi-Ten steel frame and components like the alloy rims ensure that the bike is both durable and lightweight. These materials are designed to withstand the rigors of BMX riding, whether you’re jumping ramps or doing tricks. The one-piece forged steel cranks and sealed bearings add longevity to the bike, reducing maintenance needs in the long run.
Assembly and Ease of Use
Lastly, keep in mind that the Mongoose Legion L20 ships mostly assembled. You’ll need to make final adjustments, but the process is fairly simple and should take under 30 minutes for most riders.

Maintenance Tips for Mongoose Legion L20 BMX Bike
To keep your Mongoose Legion L20 BMX bike performing at its best, regular maintenance is essential. Here are some tips to help you care for your bike:
Check Tire Pressure Regularly: Ensure your 20″ x 2.3″ tires are properly inflated. Low tire pressure can affect performance, so use a pressure gauge to keep them at the manufacturer’s recommended PSI.
Lubricate the Chain: Keep the chain well-lubricated to reduce wear and prevent rust. Clean it occasionally with a chain cleaner and apply a good-quality chain oil.
