THE KELLYS’ WAY
There are several ways how to make an e-bike lighter. Since the battery is the heaviest component of e-bike system, the easiest way is to just reduce battery capacity to lower its weight. This results in poor range, because strong, energy-thirsty motor would deplete the battery very quickly.
To achieve at least an acceptable range, some companies decrease the torque of the motor to fewer newton meters, but at the end of the day, this approach results in just low-performance e-bike with weak motor and small battery.
That is why KELLYS has chosen a completely different strategy. We wanted to create the lightest full-powered e-bike with strong motor and high-capacity battery. Because those are the elements creating true e-bike riding experience. Full power for the ultimate performance while climbing and long range for more kilometers and more fun.
To create the lightest full-powered enduro e-bike with high-capacity battery, KELLYS needed to make also the lightest full-suspension e-bike enduro frame. That is why KELLYS developed all-new THEOS F-series frame version, oriented on even lower weight while keeping the strength of the frame at the unprecedent level.
All-new frame is fully made in European Union, using new Carbon-Aramid composite structure which KELLYS have developed in cooperation with R&D automotive composite facility which researches and develops composite car monocoques for well-known hypercar manufacturer.
HIGHEST ENERGY-DENSITY BATTERY ON THE MARKET
To make all-new KELLYS THEOS F100 even lighter, KELLYS introduces the next-generation of KELYS RE-CHARGE K1 battery. Battery with mighty 825 Wh (23 Ah) and low weight of just 3.9 kilograms achieved by the highest energy density per kilogram from all the e-bikes in the world. Capacity-to-weight ratio for all-new KELLYS RE-CHARGE K1 battery totals unprecedent 211 Wh/kg (Wh per kilogram of battery weight). More powerful than ever and lighter at the same time!
For comparison, newly introduced 750 Wh battery from BOSCH is having energy density of around 174 Wh/kg and with the total weight of the battery at 4.3 kilos and 725Wh KELLYS RE-CHARGE K1 battery is having energy density of 193Wh/kg.
As other THEOS F-series e-bikes, the F100 utilises Retractable Battery System. This unique solution allows retracting the battery by sliding it out of the frame’s downtube with ease (only one 6-mm hex bolt needs to be removed) while keeping the structure of the frame untouched. None of the mechanical properties of the frame was sacrificed during the designing process, no extraction hole needs to be made in the tube wall, which would drastically reduce general stiffness of the frame. Thus, THEOS F series frame is much stronger, and because of that, it gives you better riding experience in the terrain.
SUSPENSION SYSTEM AND GEOMETRY
The suspension utilises latest 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 due to Think Link’s virtual pivot point placed in the centre of bottom bracket axis achieving constant chain length during the travel.
All-new KELLYS THEOS F100 utilises progressive enduro geometry with 150 mm travel at front and 140 mm at back, combined with mullet layout with 29” front, and 27.5” rear wheel for swift cornering, much better handling and speed.
To complete the picture of the next generation e-bike THEOS F100 is powered by the latest 85 Nm full-magnesium Shimano drive unit.
