Comfortable low step-through frame made of 6061 aluminum
The low step-through height of just 32 cm makes getting on and off effortless – also ideal for beginners or people with reduced mobility. The lightweight, corrosion-resistant 6061 aluminum frame is sturdy and easy to carry and store.
Removable Samsung battery – up to 100 km range
The high-quality 36 V / 14 Ah lithium-ion Samsung battery is elegantly integrated into the frame and offers a range of up to 100 km. It can be removed tool-free in seconds, charged externally or directly on the bike, and replaced with a second battery. It is fully charged in approx. 5 hours at any 230-V socket – keeping you always informed thanks to the integrated charge level indicator.
Powerful 250-W DynamiX-M rear wheel motor
The 250-W DynamiX-M rear wheel motor delivers up to 45 Nm of torque and supports you efficiently and reliably up to 25 km/h – whether in daily life, on your commute to work, or on tours. Arrive at your destination relaxed and sweat-free.
Clear LCD display with speedometer
The user-friendly LCD display shows all key riding data clearly and legibly – including speed, battery level, and the selected assistance mode. This keeps you in complete control of your ride at all times.
Smart BIKEGO app via Bluetooth
Via the integrated Bluetooth interface, you can pair the e-bike computer with the practical BIKEGO app. This gives you access to navigation, trip recording, and detailed real-time analysis of your riding data – connected e-biking, intuitively operated.
6-speed Shimano Tourney gears & Kenda tires
Whether a brisk city ride, a leisurely bike tour, or a climb – with the 6-speed Shimano Tourney gears, you can adjust the gear perfectly at any time. The 20" Kenda K-Shield-Plus reflective tires provide stability, puncture protection, and secure grip with their grippy tread, while reliably cushioning minor bumps.
Front & rear disc brakes
With mechanical disc brakes front and rear, you maintain full control at all times – powerful, precise, and weather-independent. Integrated brake sensors detect every activation and enhance safety with fast motor cut-off. A sturdy kickstand with a non-slip rubber foot holds the bike securely upright.
Powerful H10 LED lighting
At dusk, at night, or in rain, the permanently installed H10 LED lighting provides broad, bright illumination that far outperforms conventional bike lights. The bright rear light and additional reflective strips on the tires make you visible all around – for a safe riding experience at any time of day.
5 assistance levels & walk assist
Five assistance levels multiply your own power and let you freely adjust the intensity of your ride – even as your strength wanes, you can comfortably keep riding. The practical walk assist pushes you forward at up to 6 km/h at the press of a button without any effort, for example when pushing in an underground garage or uphill.
Folding function & compact folded dimensions
In just a few simple steps, the Stadtfalter B13 folds down to a handy 85 × 70 × 40 cm – perfect for basement, hallway, trunk, or train travel. An integrated safety lock reliably locks the folding mechanism, and the pedals fold in as well for minimal width.
Comfort: gel saddle & suspension seatpost
The padded Selle-Royal gel saddle relieves sensitive contact zones and supports a comfortable, back-friendly posture. The suspension, infinitely height-adjustable Promax seat post effectively absorbs impacts on uneven surfaces – for optimal ergonomics and increased riding comfort in the city and off-road.
