This item is currently not available.


The ST1 T with stylish brown finish is available with a 17- or 20-inch sport frame. Equipped with the ingenious Speed Drive by Schlumpf system, it delivers a very special driving experience. A quick kick with the heel, whether at a standstill or while on the move, is sufficient for the gear unit to change the entire ratio. The gear system equipped with Schlumpf Speed Drive consequently has 18 genuine gears without overlaps. The absence of two chainrings makes the Stromer even more efficient and assures a neat, tidy look and reduced maintenance. The Schwalbe Big Ben tires specially developed for Stromer give the ST1 T a more stable driving feel, combined with ideal shock absorption. To ensure you can confidently and swiftly come to a standstill, even from higher speeds, the ST1 T is fitted with hydraulic Tektro Dorado disc brakes. For better visibility, it has powerful Supernova E3 lighting system. An elegant rear rack means you can also easily carry all sorts of cargo on the ST1 T.

The Schlumpf drive is an ultra thin planetary gearing system. Gears are changed by a push button located at the axle. Simply bump the button with your heel to shift.
