Lightweight and flexibility are the hallmarks of the Upstreet SL. Equipped with powerful lights and a luggage rack, you are well-prepared and safe for your journeys, both day and night. The smart drive system from Bosch features a 400-watt-hour battery that is optimized for weight and provides more than enough power and range for your daily needs. If you plan to cover longer distances, the optional additional battery, shaped like a water bottle, can support you. This battery can be charged directly on the bike, or removed easily for external charging. The frame design, along with the high-quality carbon fork and tidy cockpit with integrated cables, gives the Upstreet SL a stunning appearance. Can the lightest FLYER E-Bike to date make your daily routine e-asy too?
