These puncture-resistant tires give you the confidence to ride over challenging terrain without worrying about flats or instability.
The front shock-absorbing suspension fork further enhances the bike’s capability to handle bumpy roads and uneven trails. Whether you’re riding through urban potholes or off-road bumps, you’ll enjoy a smoother and safer experience.

You also get 7-speed gear options, controlled via a handlebar shifter, which allow you to easily adjust the bike’s performance to suit any terrain or riding style. Whether climbing hills or cruising on flat roads, you can fine-tune the speed and effort to your preference.
Folding Design for Portability and Storage
Designed with urban convenience in mind, the bike folds down to a compact size, making it easy to store in small apartments, car trunks, or under office desks. The folding mechanism is simple and secure, ideal for those who commute using public transport or have limited storage space.
This portability also makes the S16/K2 a great travel companion for road trips and RV owners looking to explore trails at their destinations.
