Description

Taking key attributes and inspiration from the OW BOMMA, BOMMA THRUST is the new benchmark street-bike for those who demand an all-round performer for combos and traffic work. With an emphasis on “buy it and ride-it” (no upgrades needed), We took our tried and tested geometry/know-how and packaged it into a lighter stiffer machine. We then wrapped that up in a selection of exciting new colourways to form the basis of your next individual creation.

Featuring Microshift 10-speed, Shimano Hydro (MT200), hollow tech sealed BB, hydro-formed 6061 alloy frame with CNC machined components and peg mounts as standard, SnakeskinS (Sticky) tyres and 29” alloy double wall rims. To name but a few of the impressive features.

What Is OCEV?

According to California Bill No. 1271 (SEC.2312.5(d)), certain vehicles are specifically excluded from being classified as electric bikes under this code. These vehicles are categorized as Out of Class Electric Vehicles (OCEVs) for the following reasons:

  1. Highspeed Potential: Vehicles with two or three wheels that are designed by the manufacturer to be modifiable for speeds greater than 20 miles per hour on motor power alone or exceeding 750 watts of power.
  2. Post Sale Modifications: Any vehicle that has been modified to attain speeds greater than 20 miles per hour on motor power alone or to exceed 750 watts of power.

These exclusions ensure that only properly classified e-bikes can be markets as such, maintaining safety standards and regulatory compliance. Riders of OCEV's should be aware of the different legal requirements and responsibilities associated with these vehicles.

Additionally, OCEVs are designed to offer performance and features beyond what traditional e-bikes can provide. Always verify the intended use and ensure you are compliant with local and state regulations when operating an OCEV.
