Mafia Bomma TTO Purple

Matt Kyle — Sat, 07 Mar 2026 14:40:50 +0000

Here is the Bomma TTO. “The Take over” is the new benchmark 27.5” single speed street-bike for those who demand an all-round performer for combos and traffic work but find the 29” bikes just a little too big. .. 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. TTO starts life as a lightweight single speed bike, but has been cleverly designed for you to easily switch to gears down-the-line. Simply change-out the rear wheel, rear dropout insert, adding a mech and shifter and you now have a geared bike like BOMMA THRUST. All cable routing is pre-installed and we offer the mech insert as an additional part.

Featuring 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.

Mafia OW Bomma Matte Black

Matt Kyle — Sat, 07 Mar 2026 14:03:08 +0000

Introducing the @oneway_corey signature model OW BOMMA. The culmination of arguably the most respected rider in the world and the most innovative Bikelife brand: Mafiabikes.

Featuring Shimano Cues 10 speed, Shimano Hydro (MT200), high engagement rear hub, quad bearing sealed BB, alloy 6061 hydro-formed frame with CNC machined components and peg mounts a standard, bespoke CNC chainring, SnakeskinS (Sticky) tyres and 29” Sunringle aftermarket rims. To name but a few of the amazing features. OW BOMMA is the ultimate out-of-the-box complete bike, built to pro-rider standards.

When Corey made the switch to Mafiabikes it was about making a statement. This was going to be the partnership to push bikelife forward.

As bike designers, we took this responsibility very seriously. This was an opportunity to make the perfect bike we had been ‘dreaming about and pushing towards’ since 2018. The result is something Corey and Mafia are extremely proud of. A lightweight, fast, hi-spec, purpose-designed combo bike you can pedal all day, hit traffic and swerve out the crate. There is no need for upgrades with our new buy it & ride it philosophy.

Every single tiny detail has been carefully considered, tested, designed, redesigned, tweaked, prototyped, tested and considered again. We pulled on 6 years of successes and failures in bikelife, along with 15 years in the bicycle/BMX Industry.

If you wanna ride the streets, this is hands down the best bike you can buy. Don’t take our word for it, ask anyone who has ridden the OW Bomma.
