Weight and range are crucial. That’s why we created AMXXPRO: the world’s lightest full-power e-bike system, from just 6.1 kg.

The new AMXXPRO system, powering our entire new 2026 Kellys e-bike range, combines ultra-light components: a carbon battery and a high-performance magnesium motor.

• PANASONIC GXM AMXXPRO motor: Co-developed by Kellys and Panasonic, with a specialized magnesium construction and weighing just 2.56 kg, it delivers powerful performance with up to 105 Nm of torque.

• KELLYS K2 AMXXPRO carbon batteries: Weighing up to 3.5 kg, available in 900 Wh, 820 Wh, and 725 Wh versions. With an energy density of up to 257 Wh/kg, they are up to 20% lighter than competing solutions while offering higher-capacity options.

AMXXPRO delivers more power and longer range with less total e-bike weight. No compromises - just a better riding experience.
