The right frame size for your bike.
You might be asking yourself what standover height, stack and reach mean? Here’s an overview of the key terms and their meanings.
-
The frame size is crucial when choosing your bike. With Riese & Müller bikes, the frame size is measured from the middle of the bottom bracket to the upper edge of the seat tube.
Our cargo bikes and the Tinker and Birdy models have universal frame sizes. Thanks to the comprehensive adjustment of the stem and seatpost, the bikes fit heights of 1.50 to 2.00 metres.

The standover height describes a vertical line going from the middle of the pedal to the upper edge of the top tube. The standover height is crucial, especially in urban traffic. When standing astride the bike, there needs to a minimum “crotch clearance” of 5 cm between the top tube and the crotch.
With low step-through bikes (frames without top tube), the step-through height indicates the lowest point of the upper edge of the frame.
Note: With frames with a shorter top tube length (see E), the top tube generally has a steeper angle than frames with a longer top tube length. This leads to a smaller frame having a greater standover height than a large frame.
-
The stack describes the difference in height between the middle of the bottom bracket and the middle of the upper edge of the head tube. The higher the stack, the more upright the seating position will be.
-
The reach is measured by a vertical line from the middle of the bottom bracket to the middle of the upper edge of the head tube. The greater the reach, the more your upper body will stretch forwards.
-
The top tube length describes a horizontal line from the middle of the upper edge of the head tube to the middle of the seat tube. The top tube length is used to determine the seating position and seating comfort. The stack and reach enable detailed conclusions to be made.
-
The wheelbase describes the horizontal clearance between the middle of the front and rear axle. This has an impact on riding dynamics and affects the smooth running and agility of the bike. The longer the wheelbase, the smoother the bike will travel. The shorter the wheelbase, the more agile the bike will be.
-
The overall length describes the total length of the bike from the rear edge of the rear wheel to the front edge of the front wheel. This figure is useful, for instance if the bike needs to be transported, whether in a lift, on a train or on the rear carrier of a car.
-
The bottom bracket height is measured from the middle of the crank bearing to the ground. As the tire width can affect this figure, often more than one figure may be given.
