Booda Bike Astro - S




















Astro
Single-speed commuter bike
The Booda Bike Astro is a low-maintenance, single-speed, belt-driven commuter bike: with one gear there is no derailleur or shifter to adjust, and the Gates CDX carbon belt needs no lubrication. It combines a steel frame, a carbon fork, a drop handlebar, hydraulic disc brakes and 28 mm Schwalbe Pro-One tubeless tires for fast, agile riding on asphalt, in sizes S, M and L.
Designed for performance
A single-speed, belt-driven bike for those who love fast-paced cycling and want an agile ride. Thanks to the road wheels, its performance is best used on asphalt. The frame geometry and the components are matched with a focus on performance. The Gates CDX carbon drive system provides efficient, low-maintenance riding. The steel frame is flexible enough to absorb uncomfortable vibrations, yet stiff enough not to degrade the riding experience.

Steel frame. The frame is the most important element of the bike, so it receives special attention in the design. Thanks to the material properties of steel, it pleasantly dampens vibrations, yet gives enough rigidity to make cornering a real experience.
Single speed. One gear and no shifting: the bike is equipped with the Possible SpinnerOne straight-pull 24-hole wheelset, designed specifically for belt-driven bikes. The lightweight rear hub produces a distinctive, satisfying buzz.
About 9 kg. The bike weighs approximately 9 kilograms without accessories, which is low for a steel-framed, single-speed bike of this type. This is thanks to the high-quality steel frame and the carbon fork. Low weight contributes to a comfortable and enjoyable ride.
Hydraulic disc brakes. The hydraulic disc brake system is one of the lowest-maintenance braking solutions. It offers high efficiency at an affordable price and can be upgraded to a higher-end braking system if desired.
Gates Carbon Drive system. The Gates Carbon Drive belt system is clean, quiet and virtually maintenance-free. It requires no lubrication, does not rust and lasts significantly longer than a traditional chain. A premium choice for smooth, reliable riding.
Internal cable routing. Every detail of the bike was carefully designed to keep it clean and good-looking, which is why internal cable routing is standard.

Possible SpinnerOne straight-pull wheelset (24-hole)
Straight-pull front and rear hubs, suited to the Gates rear sprocket on the Rohloff belt line used on single-speed bikes.

Power-tuned riding position
The frame geometry of the single-speed bikes is tuned for performance, so you can get through the city’s obstacles as agilely as possible.

Gates CDX carbon belt drive
The Gates CDX belt drive is a durable system that delivers high performance and reliability with low maintenance.

Hydraulic disc brakes
Equipped with hydraulic disc brakes for reliable safety. Whether it's emergency braking or descending a slope, you can count on maximum stopping power. We really like TRP brakes: they are highly effective and extremely reliable.

High puncture resistance, tubeless sealant
Tubeless tires come with Effetto Mariposa Végétalex sealant, which immediately seals smaller punctures from inside the tire (Schwalbe Pro-One 622x28 tires).
Who is the Booda Bike Astro for?
- City commuters. One gear, a belt that needs no lubrication and hydraulic disc brakes keep maintenance low for daily rides.
- Riders who like fast, agile riding. Performance-tuned geometry, road wheels with 28 mm tires and a drop handlebar.
- Anyone who prefers simplicity. No gears to adjust and no chain to oil.
