Description

The Flyer Upstreet SL 3.10 is a lightweight urban electric bike that proves a city e-bike doesn't need to be heavy to be effective. Powered by the Bosch Performance SX 55Nm — the most compact motor in the Bosch range — it weighs considerably less than most of its competitors while offering more than sufficient assistance for daily urban commuting.

Its 400Wh battery sits discreetly in the down tube, giving it the appearance of a classic bike with a sporty silhouette. The sporty geometry and refined finishing typical of Flyer make it a bike you're proud to carry upstairs and park outside the office. Components are selected for their reliability and lightness.

For active city dwellers who want an electric bike that doesn't turn stair-climbing into a chore, and who want to arrive at work looking good without breaking a sweat, the Flyer Upstreet SL 3.10 is the obvious answer: light, elegant, and fiercely effective.

Bosch Performance SX - 60 Nm

Bosch Performance SX - 60 Nm

Lightness reinvented. The Bosch Performance Line SX is the motor that blurs the line between electric bike and muscle bike. With 60 Nm of torque and a featherweight, it is discreet where others are essential - for a driving experience that remains above all natural, agile and pleasant. Designed for the thinnest frames and sportiest geometries, the SX is aimed at cyclists who want the electric boost without sacrificing the lightness or feel of the traditional bike. The assistance is lively and precise, perfectly dosed to enhance your pedaling without ever replacing it.
Bosch Compacttube 400 Wh

Bosch Compacttube 400 Wh

Lightness above all. The Bosch CompactTube 400 Wh is the battery designed for bicycles where every gram counts. With 400 Wh of capacity in a deliberately compact format, it is aimed at cyclists who favor the agility and maneuverability of a light bike, without giving up electric assistance on a daily basis. Its reduced format allows discreet integration into thinner frames and sportier geometries - where a standard PowerTube could not find its place. Ideal for urban outings and short to medium distance journeys, it offers most of the autonomy in the most compact format in the Bosch range.
