After 3 years of development by Kellys’ R&D department and cooperation with our European partners, the time has come to introduce all-new Kellys THEOS F-series.

Kellys Theos F is the first full-suspension e-bike in the world made of new generation material called thermoplastic hybrid steel-carbon composite, a.k.a. FEATHER which we use in cooperation with our friends from Belgian technology company Rein4ced. This material combines much stronger thermoplastic binder, carbon fibers and inox steel microfibers which reinforces the material even further. Not only the material is revolutionary, but also the way the frame is built out of it. Thermoplastic hybrid steel-carbon composite frames can be built by robots in a European factory for premium quality and ultimate performance. 

Compared to carbon fibre resin composite the all-new thermoplastic hybrid steel-carbon composite is:

• 200% more impact-resistant
• 200% more durable

• Without weight penalty
• Produced by advanced robotic production for even better quality
• Recyclable

The all-new THEOS F comes in two variants: Super-Enduro with 180/170 millimetres of travel and Enduro with reduced travel of 150/140 millimeters. Despite the variant, THEOS F utilises a mullet layout with 29” front, and 27.5+” rear wheel for swift cornering, much better handling and speed. The new chassis is full-composite, which means there are no metallic inserts used to increase the durability even more and reduce weight. The suspension uses the latest custom-tuned Think Link virtual-pivot suspension platform with asymmetrical damper kinematics to achieve desired geometry while keeping all Think Link benefits such as sensitivity, brake- and drivetrain-independence and no pedal kickback. 

RETRACTABLE 720 WH BATTERY

THEOS F comes with a totally new power source. The Kellys Re-Charge K1 Li-ion battery is exclusively co-developed for THEOS F by Kellys-BMZ cooperation.

• The Kellys Re-Charge K1 offers mighty 720Wh and capacity of 20 Ah for outstanding range and performance.
• Thanks to patented internal cooling system and new-generation power cells, the battery has even better capacity-to-weight ratio than before. Now you have much more juice and the bike handling in terrain is exceptional because of low weight.
• On top of that, the new Kellys Re-Charge K1 battery comes with a totally new retractable fixation system. This unique solution allows for retracting the battery by sliding it out of the frame’s downtube with ease while keeping the structure of the frame untouched, avoiding a huge holein the side of the down tube, which would reduce frame rigidity and worsen the bike's behaviour during aggressive riding.  

DRIVETRAIN

To complete the picture of the next generation e-bike THEOS F is powered by the latest Shimano drive units.
