Origin and Mission

Fly Bikes started in 1999 in Vigo, Spain. The company was born out of pure love for BMX and has been committed to providing the newest technologies and innovations in BMX. Their ultimate goal is to offer the best ride possible.

Technological Innovations

The company has been a pioneer in several areas, including removable gyro tabs, 'press fit' bottom brackets, and one-piece crank arms. They were also the first to introduce BMX-specific removable brake mounts. In 2005, they introduced bigger 2.25 tires and 'Silkworm' casing technology. In 2006, they brought in motorcycle-style cross-laced rims, and in 2009, they created the 'Cobra' linear tube, allowing riders to replace a punctured inner tube without removing the wheel.

Team and Products

Fly Bikes has a team of riders featuring names like Sergio Layos, Stefan Lantschner, and Devon Smillie. They offer a range of products, including signature pro model frames and bars, as well as complete bikes like the Proton, Neutron, and Electron.

Public Opinion

The BMX community generally has a positive view of Fly Bikes. Users on Reddit have praised the brand for its innovative parts and durable frames. Some mentioned that the brand seems to be more popular among older riders and is well-known in Europe.

Frame: Trimoly Meets CrMo

The Neutron's frame is a Trimoly construct. It's a blend of strength and flexibility. The 100% CrMo bars and forks add durability. The Volcano-inspired design is a visual treat.

Steering: Hydroformed Steerer Tube

The 2020 Neutron features a one-piece hydroformed steerer tube. It replaces the older two-piece design. This is a game-changer for durability, especially during hard landings.

Drivetrain: Quality Components

The bike comes with a high-quality Trebol headset. It also features a stronger 510 chain and a clean Trebol Bueno crankset. These aren't just parts; they're performance enhancers.

Bars and Standover: Stability

The Neutron has bigger bars and a higher standover. These features contribute to stability. It's a bike that wants you to take control, whether you're in the air or on the dirt.

Wheels: Ruben 2.35” Tires

The tires are Ruben 2.35”, offering excellent grip. But there's a catch. The steerer tube gets clogged on dirty tracks. Keep that in mind if you're hitting the trails.

Riding Experience: The Intermediate Riders Dream

I'm an intermediate rider, and this bike fits like a glove. It's designed for freestyle and dirt riding. The geometry is just right for park tricks, and the frame can handle jumps.

Wear and Tear: A Mixed Bag

The grips and tires wear out faster than you'd expect. I also had a chain snap during a grind. It's not a deal-breaker, but it's something to be aware of.

Customization: Make It Yours

The Neutron comes with removable brake mounts and a Springhanger brake system. Want to upgrade? Fly Bikes offers options like CNC Brakes Kit and Ruben Alu Pedals.

Price Point: Worth the Investment

At $540, the Neutron isn't cheap. But it's not overpriced either, considering the quality and versatility it offers. It's an investment in your riding future.

Final Thoughts: A Solid, Versatile Choice

In summary, the Neutron is versatile and well-suited for intermediate riders. It performs well in different riding styles. However, be prepared for some maintenance and potential upgrades.
