Dutch handmade recumbents
Choose the Challenge of a lifetime

Super Lights

What you don't get for your money!

In 2004, Challenge woke everyone up with the SL series of bikes. Not one, but four series of ultra light recumbents from 18-23 pounds in various formats, low racer, mid racer, high racer and level BB. 3 cockpit formats: open cockpit, USS, and preying mantis, provide the widest choice of any manufacturer.

The heart of this technology is the butted split tube frame technology combined with carbon fiber or SL aluminum seating, carbon fork, and boom technology.

On the Seiran SL and Fujin SL you will note that the frame is one piece, from boom insertion point at the front, all the way to the rear dropouts. No welded on stays!

If you want some cush along with your SL, the mid racer Hurricane SL or level BB Mistral SL feature injection molded carbon fiber rear suspensions at the same SL weights.

Compare these bikes, and you will find no lighter bikes available in their price range.
