KELLYS Theos F60

The KELLYS Theos F60 is a modern full-suspension mountain e-bike that combines the latest technology, high durability and a powerful motor. This model is designed especially for demanding terrains, technical trails and mountain biking, where you will appreciate great handling and long range.

Innovative frame - carbon-aramid construction

One of the main features that sets the KELLYS Theos F60 apart from the competition is the unique carbon-aramid composite frame.

The advantages of this frame:

• Higher strength and durability - the carbon-aramid composite is up to 200% stronger than conventional aluminium frames and 50% more resistant to impacts.
• Lower weight - this material allows for a significant reduction in the weight of the bike, improving handling and riding dynamics.
• Better vibration absorption - thanks to the special properties of aramid, the frame can absorb shock better, which means a more comfortable ride on rough terrain.

The frame geometry is designed to provide stability at fast speeds while providing responsive steering in technical passages.

Powerful Shimano EP8 motor - 85 Nm of torque

The KELLYS Theos F60 is equipped with a top-of-the-line Shimano EP8 mid-motor, one of the most powerful e-MTB motors on the market.

• 85 Nm of torque - strong assistance even on steep climbs
• Low motor weight (2.6 kg) - better bike balance and more efficient power consumption
• Intelligent power management - adapts assistance power to the terrain and riding style
• Quiet operation - Shimano EP8 is 36% quieter than previous generation motors

The motor supports four levels of assistance (ECO, TRAIL, BOOST and WALK MODE) so you can easily adjust the power output to suit your needs.

Long range battery - 820 Wh

With an integrated 820 Wh battery, the KELLYS Theos F60 offers a long range, which you'll appreciate on longer rides.

• Range: up to 200 km (depending on terrain and level of assistance)
• Fast charging: approximately 4-6 hours on a full charge
• Perfect integration into the frame: sleek design and low centre of gravity for better stability

The battery is fully protected from dust, water and shocks, ensuring its longevity even in rough terrain.

Mullet setup - 29" front and 27.5" rear wheel

The KELLYS Theos F60 uses a combination of a 29" front and 27.5" rear wheel, which is referred to as a "mullet setup".

Advantages of the mullet setup:

• 29" front wheel - better stability and traction over terrain
• 27.5" rear wheel - better manoeuvrability and faster cornering response

This system combines the advantages of both wheel sizes to offer a great balance between stability and playfulness when riding.

High-quality suspension - RockShox 35 Silver (120 mm travel)

The Theos F60 is equipped with a RockShox 35 Silver fork with 120 mm travel, which provides smooth running and excellent shock absorption.

• Solo Air suspension - easy adjustment to rider weight
• Boost axle (15x110 mm) - improved stiffness and control over the bike
• Fork lock option - more efficient uphill pedalling

RockShox Deluxe Select+ rear shock for a more comfortable ride even on broken trails.

Powerful SHIMANO Deore M6120 hydraulic brakes

For safe stopping in all conditions, the Theos F60 is equipped with Shimano Deore M6120  four-piston hydraulic brakes.

• Strong braking power - ideal for steep descents
• 4 pistons for better distribution of braking force
• Large brake discs (203 mm) - stable braking performance even on long descents

With these brakes, you'll always have maximum control of your bike, even on descents on wet or dusty surfaces.

Shimano Deore 11-speed derailleur

The bike is equipped with a Shimano Deore M5100 11-speed derailleur for smooth and precise shifting.

• 11-51T cassette - wide gear range for any terrain
• Durable chain and derailleur - long life and reliable performance

With this kit, you' ll always find the perfect gear for climbs and fast straights.

Carbon fibre

E-bikes that use carbon fiber are a common choice among amateur and professional cyclists. Previously, it was mainly road e-bikes, but today you can enjoy the benefits of carbon on almost any type of e-bike. It remains an ideal choice among lovers of fast driving and off-road driving. The main advantage of e-bikes with a carbon frame is exceptional shock and vibration damping, they resist corrosion and wear very well and, compared to other materials, they excel in their low weight.

Motor Shimano EP 8

The Shimano EP8 electric motor, rated at 250W and 85Nm of torque, means 21% more power compared to the most powerful motor to date, the Shimano E8000. 10% lighter weight with a total of 2.6 kg thanks to the use of magnesium for the motor block. Redesigned bearings and gear connections inside the motor, resulting in 36% less friction and drag when pedalling with the drive off or above the motor assist speed limit.
