The ST1 is available in Sport and Comfort versions. In the Sport version, the ST1 comes with either a 20-inch or 16.5-inch frame. The Comfort version, with its 16.5-inch frame is easy to climb onto and off thanks to its lower top tube. The ST1 comes in the three colors: white, black or red, and is available optionally with 9-speed or 27-speed gears. A suspension fork and a City Kit exclusively tailored to the typical needs of the Stromer rider can also be supplied.
Whether you want your Stromer for getting to work, transporting items or taking a casual spin through the countryside, with three configu- rations of motor power you can select just the right Stromer for your individual requirements.
The Stromer ST1 is equipped with a brushless, direct-current motor in the rear hub that is powered by the rider. The ST1’s motor is available in three powerful configurations: Mountain 25 which produces a smooth and strong ride while still being economical, Mountain 33 for meeting the requirements of high-torque rides that involve climbing or payload towing, and Power 48 which delivers the ST1’s maximum speed of 45kph, making small work of variable terrain.
Choose between two distinct power configurations tailored to your ride needs - the ST522 battery. The battery is discretely tucked into the down tube, and can be directly accessed for onboard charging or easily removed for added charging convenience at the press of a button.
The Stromer Interface is an intuitive control panel. Tune power dispersion and monitor ride information at the touch of a button. Monitor battery charge level, engage regenerative braking and view your current speed, how far you have traveled, and even how long you have been on the road for. Change the current mode of your ST1 and even engage boost mode - riding a bike has never been easier.
