Built for wheelies, ready for more

This bike was designed for one thing first, riding on one wheel. The geometry makes it easier to find and hold balance, so learning wheelies feels more natural from the start.

At the same time, the 10-speed drivetrain turns it into a fully usable city bike. You can cruise, commute, or head out of town without feeling limited.

What makes it feel so easy to ride

The riding position is comfortable and upright, which helps with control. Large 27.5" wheels roll smoothly, the drivetrain keeps things efficient, and the 3-piece crank adds strength where it matters.

The FAT seat is built for longer sessions, so you can ride further without feeling it. Hydraulic disc brakes give you clean, predictable stopping power, even off-road.

Designed for balance and control

Lagos Snakeskin tires were made specifically for wheelie riding. At 2.5" wide, they give you grip and stability while still feeling responsive.

This setup helps you stay in line, control your balance point, and keep your flow going, whether you're practicing or just cruising through the city.

Fit and adjustability

The BOMMA 27.5" 10S is recommended for riders around 160 cm and above, but fit depends on your body proportions.

The handlebar position can be adjusted, and the seat is fully adjustable, so you can fine-tune the setup and keep the bike comfortable as you progress.

More than just a wheelie bike

If you want one bike for tricks, commuting, and everyday riding, this is it. It handles combos, daily rides to school or work, and relaxed cruising without compromise.
