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 45km/h. 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 150km, 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.




You can always recognize a Stromer at first glance. With its elegant but compelling styling, it stands out wherever it goes. The unmistakable Stromer design has undergone further refinement on the ST2; even minute details have been optimized and perfectly coordinated with an eye towards ease of servicing, comfort, operation, performance and style.
The Stromer’s designers have striven for maximum integration by following the principle of “less is more”. All the cables are neatly out of the way inside the frame. The U-shape daytime running light is subtly integrated into the frame and makes sure other road users can better see you when you are out and about. The ST2 is a real eye-catcher that only reveals all its design secrets at second or third glance.




Stromer is making and writing history when it comes to digital connectivity. The ST2’s revolutionary new user interface provides remote, wireless interaction between the bike and other touch points such as the Stromer Portal and your smartphone. This allowed our engineers to develop useful features such as remote locking and unlocking. The bike’s performance settings can be fine-tuned from your phone, wireless firmware update, remote acces to bike informations and control functions, remote bike performance tuning via Smartphone App and lock and unlock ST2 via Smartphone App.   

All of this is possible thanks to Omni, Stomer’s proprietary cloud-based platform. Omni not only enables anti-theft protection, it also stores your Stromer’s service records - making life for you and your local Stromer dealer much easier. 




The ST2’s SYNO Drive motor is a brushless, direct-current motor located in the bike’s rear hub. Since the motor is fully integrated inside the hub, the only mechanical contact is between the industrial-quality ball bearings, resulting in an incredibly quiet, ultra-efficient, and virtually maintenance-free system.

If 35Nm of torque isn’t enough to put a smile on your face when you first put pressure on the ST2’s pedals, then its 500 Watts of power as you tackle hills or race to get to work on time, surely is. The ST2 provides pedelec assistance up to 45kmph, so you can save energy even above cruising speed. To handle all this power, the ST2 is equipped with  front and rear thru-axles for increased rigidity and security. 




The ST2 opens up new dimensions with its operating range. Thanks to an even more efficient motor and a larger battery, you can now cover up to 180 kilometers before your ST2 will need fresh energy. Despite its capacity of up to 983 watt-hours, the lithium-ion battery is housed discreetly in the down tube of the frame.
You can choose where and how to recharge the battery of the ST2. It can either be charged inside the frame via an external charging socket. Or the energy storage unit can simply be removed from the frame and recharged wherever you wish, using a charger. And the recuperation mode means you actually generate energy when you brake; that energy is then fed back into the battery.

The ST2 is available in Sport and Comfort versions. In the Sport version, the ST2 comes with either a 20 or 17-inch frame. The Comfort version, with its 17-inch frame, is easy to climb onto and off thanks to its lower top tube. Both versions are equipped with 20-speed Shimano gears.
The ST2 is available in high-gloss white or matt black, and fitted with an elegant City Kit tailored exclusively to the requirements of Stromer riders. Alloy fenders, carrier and the powerful headlight and rear light all match the overall design of the ST2.




The ST2 is accessorized with everything you need to make your ST2 experience safe, smooth and comfortable.

  • Disc Brakes: All Stromer models are equipped with hydraulic disk brakes. The brake performance is tailored to the high speed and weight of the bike so that you can always brake safely and under control.
  • Tires: The ST2’s tires have integrated puncture protection. Schwalbe’s BigBen tires weredeveloped especially for Stromer, to offer increased shock absorption for the most comfortable ride.
  • Carbon Fork: Carbon gives you lightness and performance combined with the flexibility to muffle bumps and vibrations. Put the rough road behind you and the smooth one ahead.
  • Saddle: A custom made saddle has been created to fit the ST2, in-line with its sleek design yet not compromising ergonomics and comfort.
  • City Kit: Custom-made Stromer fenders blend in with the overall aesthetic,  yet protect you in the most adverse conditions. Our Stromer Racktime carrier has been specially crafted to fit snugly above the rear wheel; it’s streamlined, functional and sturdy. The ST2’s customized Supernova headlight packs 165 lumens into an impressively small unit, while its rear light is highly efficient - guaranteeing you get seen.
