  • Made for your everyday hurdles
    Hello flexibility

Lightness and flexibility are the hallmarks of the Upstreet SL. With powerful lights and a rack, you will be safe and well-equipped on the road day and night. The smart drive system from Bosch with a 400 watt-hour battery is weight-optimized and offers more than enough power and range for your everyday life. If you take longer journeys, the optionally available additional battery in drinking bottle format will provide assistance. The battery can be charged on the bike. The battery can be removed from the side for easy external charging. Can the lightest FLYER e-bike to date also make your everyday life e-asy?

Absolutely e-asy!

Leave not only cars, but also your everyday hurdles behind you. Simply carry the lightweight e-bike up the stairs, effortlessly pedal up a mountain and arrive at the office feeling relaxed. The compact “Bosch” motor is your reliable power supplier.

Neat and Clean 

Thanks to the well-thought-out cable routing in the handlebar stem, the Upstreet SL cuts a fine figure with a particularly neat look. What’s more, the latest generation of Bosch control units ensures greater clarity and control in the cockpit thanks to their minimalist design and wireless transmission.

Not a “one-night stand”

This city speedster is a reliable companion. Thanks to the “PowerMore” additional battery option, the Upstreet SL also supports you on long journeys and remains by your side thanks to its particularly high-quality components.

Stay Safe

Protected and clever in urban traffic: Thanks to the smart anti-theft functions, navigation and updates via the app, you’ll always have everything under control.

Time to shift

It takes less than 150 milliseconds to change gear – even under full load. In combination with the “Gates Carbon Drive” belt, the Upstreet SL is completely reliable and maintenance-free.
