About this product
La Plaga wanted an accessible bike to help more riders get into bike life. The Bomma La Plaga ST takes the geometry of the alloy 27.5" Bomma and pairs it with a hi-tensile steel frame and a simple single-speed setup built for wheelies.
Integrated peg mounts let you bolt pegs to the dropouts instead of the rear axle. The bike also comes with a La Plaga wheelie seat and pad set, a Shimano hydraulic rear disc brake and wide Lagos Snakeskin tyres for swerving.
Key features
- 27.5" hi-tensile steel frame with integrated peg mounts
- Single-speed drivetrain with 170mm chromoly crank arms
- Shimano hydraulic rear disc brake with 160mm rotor
- 27.5" × 2.5" Lagos Snakeskin tyres
- La Plaga wheelie seat and pad set
- Front brake supplied in the road kit
