A frame proven over generations.
A frame with increased stiffness, based on a time-tested design, offering perfect handling characteristics together with an unforgettable riding experience. The drop-shaped main frame profile provides excellent aerodynamic properties and has also become an integral part of the typical KOSTKA footbike look. Increased rider space, optimal rigidity and elegant lines are the basic elements of the new generation frame.
Without the ankle brace and with functional elements.
The integrated stand hole, front brace, special welds to increase the frame's stiffness and resistance to contact with uneven ground are already a standard we are rightly proud of. To increase your comfort, we have built the footbike on a tapered frame concept with a 65mm wide hub. This solution, together with the recessed rear wheel axle, prevents the rebound leg from contacting the footbike, which positively affects the overall riding comfort. The stainless steel adhesive elements on the top of the footplate ensure long-lasting footboard life and anti-slip properties.
Wheels and hubs. With low rolling resistance.
Our own hub design was developed with high functionality and easy maintenance in mind. The innovative floating fit of high quality, low friction Japanese bearings ensures precise clearance definition and therefore no complicated hub adjustments are required. Easy removal of the hub ends allows for easy maintenance. The direct knitting with Sapim stainless steel spokes guarantees high rigidity.
When tires matter.
Schwalbe Marathon Racer tyres are the lightest tyres in their category. A special rubber layer reinforced with a double nylon membrane provides puncture protection. The SpeedGrip natural rubber compound ensures excellent handling characteristics with minimal rolling resistance. The tyres feature a reflective side stripe and can be inflated with high pressure. The choice of tyres is one of the main aspects of a comfortable and effortless ride in footbikes.
High-quality Shimano 4000 brakes together with double-wall rims with a reinforced wall and a turned braking surface for increased braking performance, guaranteeing maximum safety and precise delivery of braking force. Ergonomic levers provide perfect comfort. The brakes are also easy to maintain and adjust and are highly resistant to external influences.
Kick off. Bring it up.
The rear heel stop ensures a firm and accurate standing leg position. It is made by milling from high-strength aluminium alloy. Use is found when bouncing or elevating the footbike foot when negotiating obstacles such as curbs. Its shape is optimized for all types of footwear. It can also be completely removed. The heel stop extends the tread surface and increases the space for the rider, making it a little easier to bounce and change feet.
