Kalkhoff offer something that's unusual in the world of electric bikes. Rather than make bicycles in one size and hope for the best (like most ebike manufacturers) they produce bikes in the full range of sizes and styles.

If you're not sure which size is the best fit for you, the tables below will help you decide. We've produced the table for both metric and imperial measurements.

Inside leg measurement
It's important to make sure you have the right stand-over height, the space between your crotch and the bike's crossbar (if it has one) just in front of the saddle. This is measured by standing barefoot with your feet approximately 20cm (8 inches) apart and then measuring from the floor to your crotch. Knowing your height which is also useful for frame sizing.

Kalkhoff state their frame sizes in centimetres so this is how we display the options on 50cycles. Many British cyclists will be more familiar with frame sizes in inches. Here are the equivalents. Please note that the 45cm frame size is available with different size wheels, depending on the model. From 2010, the Pro Connect Alfine, Pro Connect LX and Pro Connect S models are available with a 45cm frame and 28-inch wheels. The 45cm frame Agattu and Tasman and all Sahel frames come with 26-inch wheels.
