MORE WAYS TO RIDE: INTRODUCING THE KELLYS THEOS AX SERIES

24. June 2026
For years, KELLYS e-bikes have been built around one principle: giving riders reliable, efficient and enjoyable assistance - wherever their adventures take them. For 2027, those possibilities just got bigger.
We are proud to introduce the THEOS AX series - a new KELLYS e-bike platform powered by the AVINOX drive system. Raw power, instant response, advanced connectivity. Built for riders who want more from every meter of trail.

A NEW FORCE IN THE KELLYS LINEUP

The THEOS AX is not here to replace. It is here to expand.
Our Panasonic AMXXPRO-powered range remains the backbone of the KELLYS e-bike portfolio - refined, efficient and built for riders who think in kilometers. The THEOS AX series is something different. A new option for a different kind of rider, and a different kind of ride.
More ways to ride. That is what this is about.

BUILT AROUND THE AVINOX DRIVE SYSTEM

At the heart of every THEOS AX is the AVINOX M2S motor - a compact unit weighing just 2.59 kg, delivering up to 130 Nm of torque in standard operation and up to 150 Nm in Boost mode. Steep climbs, demanding terrain, technical trails - the system responds instantly and holds nothing back.
An integrated 800 Wh battery provides ample capacity for long sessions in the saddle, while keeping the frame clean and balanced. A full-color OLED display, wireless handlebar controls and advanced connectivity complete the package — giving riders full control over how they ride and how they monitor their performance.
Powerful. Responsive. Connected.

READY FOR TECHNICAL TRAILS

The THEOS AX90 is the flagship of the series — and it shows exactly what this platform is capable of.

Its aluminum frame is built around a proven Horst-Link four-bar suspension design, delivering 160 mm of rear wheel travel. Up front, a 170 mm RockShox ZEB Ultimate fork handles whatever the trail throws at it. A SRAM GX Eagle AXS Transmission drivetrain brings precise wireless shifting, Shimano Deore XT brakes with Galfer 200 mm rotors deliver confident stopping power on steep descents, and Schwalbe Magic Mary tyres provide exceptional grip when conditions get demanding.
This is an e-bike built to be ridden hard.

TWO SYSTEMS. MORE WAYS TO RIDE.

With the THEOS AX series, KELLYS riders now have a genuine choice.
Our AMXXPRO-powered models continue to set the benchmark for efficiency, low system weight and outstanding range — the long game, done right. The THEOS AX series brings a new dimension: maximum power, sharp response and deep digital integration for riders who want to push further on technical terrain.
Different technologies. Different riding experiences. The same KELLYS commitment to quality, innovation and adventure.
Because every rider is different — and there should always be more ways to ride.
