Powerful motor
With our newly developed SYNO Drive ll motor, the ST3 delivers a massive 820 W (USA 600 W) and a torque of 44 Nm to the hub. That means: You arrive at work neither soaked in sweat nor completely exhausted – unless, of course, you want to. Like all our e-bikes, the ST3 draws its energy from a very powerful battery with a range of up to 180 kilometers. This battery is not only extremely economical, but also reabsorbs the released braking energy (recuperation).
Ideal frame geometry for commuters
Short chain stays, short wheelbase, low bottom bracket: all this and more makes the ST3’s frame geometry ideal for the needs of commuters and perfectly matched to the e-bike’s 27.5” wheels. Despite its comfortable running smoothness, the ST3 is therefore extremely nimble – a must in busy city traffic.
Riding with a safe feeling
The ST3 not only makes your daily journeys fun, it also gives you an extremely safe ride. The outstanding grip of the Cycl-e ST tires from Pirelli, the specially designed LED front light with headlamp function or the Stromer brake system with four pistons at the front wheel and two pistons at the rear wheel ensure this high level of safety.
Elegant look – smart extras
Last but not least: The ST3’s visual and practical features also make it perfect for modern commuters. For example, the uncluttered design with hardly any visible cables, «seamless» locking and unlocking via Bluetooth, «keyless» battery ejection and, of course, a carrier. Optional extras such as a phone holder or a suspension fork are also available.
Individual sitting position
For the ST3, in addition to the Sport and Comfort frame in various sizes we have also developed two different stems (Urban and Urban Comfort) and three different handlebars. You can freely combine these components so that you can enjoy the unique Stromer riding experience in a sitting position that is perfect for your body size.
