    Hydro formed step down frame

    S-Electro Stepdown features a double butted hydro-formed full suspension alloy frame with integrated motor mount and internal battery. The step in the frame is designed for improved clearance during use - easier mounting as well as a more comfortable bike to use in traffic. Hydro forming means that the frame can have thinner sidewalls, complex shapes and curves that makes it stronger and lighter than comparative alloy frames with regular tubing. Hydro forming is the process of forcing tubing into a negative mold with internal pressurised oil and or water, resulting in stronger - lighter tubes. The combination of oversize downtube and hydro forming, makes for a very strong frame.

    Drive system, power and display.

    S-Electro Stepdown is designed around a Shimano Steps E8000 motor. This motor is paired to a high capacity 720Wh internal battery giving the Stepdown an unrivalled range of pedal assistance. The Shimano Steps LCD display is intuitive and easy to use, also indicating battery levels and shows all info needed for the electric system.
