We introduced the concept of ”Sectionalized design” in the Spear model, where each frame section serves a specific purpose.

6 advanced materials from TeXtreme and Mitsubishi Chemicals, including the next-level ultra-high modulus Pitch-based carbon fiber ever used in the bike industry. 350 pieces of carbon fabrics stacked to its position, delivering ultra-high stiffness and lightweight agility.

All together, consolidate with True-One-Piece molding technology, no joint, no weakness, and a truly integrated frame body.

Computational Fluid Dynamics（CFD）

Based on Computational Fluid Dynamics (CFD) simulations for developing and iterating tube shapes, it is regarded as an important tool in Spear’s design updates. CFD analysis enables rapid direction clarification and quantifies benefits, reducing trial and error in the development process.

Even faster than aero bikes

We collaborated with the AeroCoach team to conduct extensive wind tunnel tests at Silverstone Sports Engineering Hub in the United Kingdom, simulating real-world riding conditions and optimizing using 280,000 sets of data.

Spear It leaps in aerodynamic benefits. Compared to the Exceed, it reduces drag by 6 watts on a 40-kilometer undulating ride with 800 meters of total elevation gain and 40 km/h relative wind, shaving 15.27 seconds from the finish time.

Wind Eye

What makes Spear stand out from all other bikes.

The iconic Wind Eye structure expelled turbulence air created from pedaling and suppressed the low-pressure zone. Saves you additional 2.66 watts at a relative wind speed of 40kph.

More Aerodynamic
More Comfortable

17mm maximum seatpost deflection distance effectively reduces severe vibrations from rough roads while mitigating road surface bumps. Compared to the Exceed, the Spear increases vertical compliance by 23%.

Powerful Bike
Pure Riding Pleasure

Providing the pure riding experience is written in our DNA, each bike we build not only is to increase your riding performance but also pushes you across the boundaries. SEKA Bikes hears your voice and infuses them into your dream bike build. To help you go faster, smoother, and have more fun!

All new Rapier integrated handlebar

Utilizing True-One-Piece molding technology, designed to a perfect match for Spear. 5mm narrower on hood, 25mm flare on the drop, incredible ergonomic grip, and tailor built for combat field racers. Compared to the Exceed Gen 2 monocoque handlebar, stiffness increases by 5.2%. Weight decreases by 20g, with a weight of only 310g (375mm-100mm, without hardware).
