i:SY Skyfly S10

At just 16.9 kg, the i:SY SKYFLY S10 is the lightest i:SY from our company. With the new, super quiet and light BOSCH Performance Line SX motor, you won't hear anything other than the wind. The Skyfly S10 is equipped with the sporty SHIMANO Tiagra 10-speed derailleur gears.

The new, modern frame shape made of carbon with the round tubes that are flattened inwards takes the i:SY design to a new level. To save weight, the Skyfly S10 was designed without a luggage rack, but this can be retrofitted.

The motor support is switched on and off via the system controller in the main pipe. Complemented by the Mini Remote on the handlebars, the range of functions is expanded, including the pushing aid and the light switch. Additional functions can be controlled on the KIOX 500 color display.
The i:SY SKYFLY S10 is available in two battery strengths: the BOSCH PowerPack with 400 Wh or 545 Wh.

i:SY Skyfly E5 ZR

An absolute highlight! The new i:SY Skfly E5 ZR is the first e-compact bike made of carbon. At under 20kg it is a real lightweight. The new built-in BOSCH Performance Line SX with 55 Nm is not only extremely light, but also very quiet.

The i:SY SKYFLY E5 ZR is equipped with the 5-speed hub gear from SHIMANO and the low-maintenance GATES® CDX Centertrack timing belt.

With the KIOX 500 color display you can see everything clearly. The BOSCH Smart System ensures that the display, control unit and motor are cleverly linked.

Editorial conclusion

Only at second glance do you recognize the special feature of the i:SY in the top version: the frame and fork are made of carbon instead of aluminum, which brings a significant weight advantage. The elegant city bike weighs less than 20 kilos, which of course makes handling noticeably easier. In terms of technology, it is impeccably equipped with Bosch CX, e-bike-specific five-speed gearbox and strong four-piston brake at the front.
