Big Wake is a 29er cousin of the Cojones Expert. REAL CUSTOMER says: "Dramatically exceeded my expectations....Most fun I've had on a bike in my Life" "...Even if you are a beginner...you should have no problem (putting it together)" (see Gravity Cojones dirt jumper build, ride, review video below)

LIGHT WEIGHT This bike is lighter than most any other bike in its price range AND has much higher level parts.

SWEET HANDLING
Engineered for the streets, built to fly—Gravity 29er BMX delivers pro-level control and confidence so you can ride harder, faster, and have more fun doing it.

Love the feel of $700+ adult BMX bikes? Get that same thrilling ride for nearly half the price with the Gravity 29er Dirt Jumper/Cruiser.

CUSTOMER PROVEN
The Gravity Big Wake 29er BMX is customer-proven and built for serious fun. It features a strong, lightweight aluminum frame—the same material used on nearly all high-end dirt jump and BMX bikes.

THE DIFFERENCE
Many riders compare it to the SE Big Ripper, which sells for over $800. The Big Wake gives you a similar ride and style for about half the price. With quality components and standout looks, it delivers top-tier value without the high-end cost.
