The Karlstad is the top level bike in the Simmonsohn adventure series. We think it’s perfect for the couple who want to explore tandem paths, tracks, roads and lanes. Running on slightly larger 700c wheels the Karlstad can cover more miles than the mountain series but can still handle some extra weight and some light rough.
The Karlstad features Simmonsohn’s triple triangle aluminium adventure series frame. The new frame design results in a low step over height for the stoker position. Up front is a responsive, lightweight Cromoly fork. The upgraded 24 speed transmission system comprises of Shimano EZ fire push button gear shifters with super precise Shimano derailleurs.
The large range of gear ratios will help you cope with everything the terrain throws at you. Front and rear Tektro alloy V type brakes coupled with Simmonsohn double wall rims and Schwalbe Marathon tyres give excellent control on the road or tracks.
A combination of functional design and quality components.
