Hase introduced a new KettWiesel in the spring of 2007. The new KettWiesel AL has a lighter aluminum frame and lighter is always nice. The KettWiesel’s road holding, maneuverability, and stability remain unchanged.

If you want a Long-Wheel-Base (LWB) recumbent with Under-Seat-Steering (USS) and rear suspension the Hase Tagun is about your only choice. The rear suspension does a good job of soaking up bumps but it also adds a 5 to 7 LB weight penalty over other LWB USS bikes.
