The ST2’s new and more compact SYNO Drive motor not only provides 500W of power, but an enormous 35Nm of torque too: that’s more than enough to put a very big smile on your face when you step on its pedals. It also comes as a big relief when the challenges of hills or steep roads lie in your path. You can control the three modes of motor support and the level of regenerative braking with the controller next to the grip on the handlebar.
The ST2’s low maintenance and highly efficient SYNO Drive motor offers assistance up to 30 mph. If you live in an urban setting, commute by bike, or just like long cruises on country roads, you’ll soon understand why we like to say that the ST2 is “faster than a car.”
With a range of up to 130km, the ST2’s new proprietary Li-Ion battery puts the ST2 in a league of its own. The 48-Volt battery contains a massive 814Wh of energy. Despite this significant increase in endurance, the ST2’s battery still tucks neatly away into the down tube.
The ST2 offers complete flexibility when it comes to recharging the battery. It can be charged through an external socket in the frame with the battery in the bike. Or, with the twist of a key and the press of a button, the battery can be removed and charged at home, at the office, or even in a café with the Stromer battery charger.
The ST2 can even be recharged while cycling. When used, the braking system of the ST2 generates energy which is then fed back into the battery: this is known as regenerative braking. Furthermore the ST2 is EnergyBus compliant. EnergyBus is an open standard for the integration of, and communication between, the components of light electric vehicles.
