Kellys Theos R30 P 29"/27.5" 36V 20Ah 725Wh steel blue electric bike (76117)

Whether you are a mountain biking enthusiast or someone who wants to combine pleasure with efficiency, Kellys Theos R30 is a bike that can exceed your expectations and enable you to conquer routes that once seemed unreachable.

The mind and heart of the Theos R30 lies in the PANASONIC GX Ultimate motor, one of the lightest, most compact, yet powerful in its class. Weighing only 2.9 kg and delivering up to 90 Nm of torque, it is equipped to handle both rough off-road trails and demanding climbs. With the exceptional AUTO mode, which intuitively adjusts the level of support to your riding and trail conditions, the unit provides both powerful assistance and optimal energy use.

The KELLYS Re-Charge K1 Li-ion battery was co-developed by Kellys and BMZ to deliver a solid, efficient, yet subtly integrated power source. Offering a significant capacity of 725 Wh and 20 Ah, it not only powers the motor but also enables longer trips with less frequent charging.

The color Bluetooth® display on the Theos R30 bike not only provides all the key data about your ride but also allows navigation use, which is invaluable when exploring new terrains and routes.

The bike frame, manufactured in Europe, provides not only durability but also precision and stiffness, thanks to technologies such as the Think Link® suspension system and the use of BOOST standards. Made with advanced, robotically welded 6-series aluminum alloy, it was designed with performance and durability in mind, no matter how demanding the terrain.

The use of ROCK SHOX suspension, both in the forks (35 Silver TK, 150 mm travel) and the rear shock (Deluxe Select R, DebonAir+), makes the ride smooth, shock-resistant, and comfortable, even in the most challenging off-road conditions.
