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.

STEPDOWN FRAME

The S-Electro Stepdown's most noticable feature is the lack of a top tube. This design feature is to improve stand over clearance and make swinging a leg over the bike easier, also perfect for people wearing suits or skirts.

FAQS
  • FAQ

  • Can I use the Stepdown on trails?

    The Stepdown is primarily designed for urban environments. Pathways and light trails are fine, but don’t hit jumps, drops or technical sections.

  • Can I modify my electric motor for more speed?

    No. We do not recommend modifying your motor. Any modifications will void your warranty, promote premature component wear and could compromise structural integrity of your frame.

  • Can I fit bigger wheels on my Stepdown?

    If you want to fit bigger tyres, we suggest dropping the rim size to 27.5 wheels. Then you can fit a selection of bigger tyres for more comfort and grip.

  • Can I ride the Stepdown as a classic non assist pedal bicycle?

    Yes, you can, you will notice the extra weight associated with the electric drive system, but other than that, you can pedal and ride the bike as normal.
