Multi-day commutes on a single charge, comfortably.

The S-Electro Diamond Step is a commute focused electric assisted sport bicycle. Whether you are commuting to work and back or just out for weekend cruises, the Diamond Step does so in comfort thanks to the 27.5" Plus tyres and suspension fork. Accessorize with panniers and fenders, and you can commute or even tour all year round with the Diamond Step. The low standover frame of the S-Electro Diamond Step means that even if you are wearing a suit, or skirt, its easier to mount. A powerful Shimano EP8 motor and super high capacity 720Wh battery completes the very capable, very fun S-Electro eBike and gets you there with less effort. Multi-day commutes on a single charge is nothing to brag about, unless your bike can't do it. Ours can.

Hydroformed step down frame

S-Electro Diamond Step features a double butted hydroformed 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. Hydroforming 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. Hydroforming 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 hydroforming, makes for a very strong frame.


Drive system, power and display.

S-Electro Diamond Step is designed around a Shimano Steps EP8 motor. This motor is paired to a high capacity 720Wh internal battery giving the Step an unrivalled range of pedal assistance. The Shimano LCD display is intuitive and easy to use, also indicating battery levels and shows all info needed for the electric system.


















  1. Massive battery means massive assist range and many commutes on a single charge.
  2. The Diamond frame makes commuting in work attire a pleasure - hop on easily in your power suit or even that summer dress that you love.
  3. Electric assisted commuting bikes are great for getting around town quickly and easily. Less congestion on the roads, less pollution, and you get assisted exercise making it a breeze. What's not to love?
  4. Geometry and bigger plus tyres are comfort orientated, but also makes for confident handling in traffic.
  5. The suspension fork is easy to set up and a great quality fork that does an excellent job at smoothing out bumpy terrain.
  6. Rack and fender compatibility means that the Diamond Step is perfect for commuting or touring.




The S-Electro Diamond Step's most noticable feature is the unusually slanted 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.


Manitou Markhor Suspension fork

A Manitou Markhor 120mm fender ready suspension fork offers great damping and smooth movement with very little break away stiction. The Markhor is light, easy to set up for specific rider requirements and the benchmark in this class.



Geometry on the Diamond Step has been designed with focus first and foremost on commuting in comfort, and secondly on pedaling efficiency. Getting there quickly is only fun if you can be comfortable doing it.



The S-Electro Diamond Step is fitted with purpose chosen commute orientated components. This means that more than giving you the most possible bike for your money, the Stepdown will also offer full system synergy - where the whole discipline of commuting is considered, and the result is even better than the sum of the parts. A 34t front chainring, and Deore 11 speed rear derailleur is matched to a 11-51t wide range cassette, offering excellent climbing and top speeds.



SUNRingle Duroc 35 wheels are strong and relatively lightweight, and is tubeless ready from the box. Factory pre taped rims mean that you only have to add sealant and valves along with tubeless tyres and you're good to go. The 27.5" + Tyres adds traction and comfort and as a result, helps to reduce fatigue on longer rides.



The Diamond Step is focused on integration from the get go - Internal battery, internal cables, integrated motor mount, front and rear fender ready, pannier rack mounts and even features cable routing for rear lights.

  • Can I use the S-Electro Diamond Step on trails?

    Step is primarily designed for urban environments, pathways and light trails. Don’t hit jumps, drops or technical sections. Other than that, it is an MTB and can be taken on XC rides.

  • 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 29" wheels on my Diamond Step?


  • Can I ride the Diamond Step as a "normal" 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.
