Zehus Bike+ all-in-one is an innovative Italian product that in a compact rear hub - which wheighs less than 3 kg - hosts a brushless motor, battery, sensors, control unit and Bluetooth interface.

The all-in-one hub is controlled via  Bluetooth by a smartphone App (iOS and Android) to select different power modes and manage your trip data. Customisation allows to set up different parameters such as the level of motor assistance, intensity of brake regeneration and so on. 

When set to BIKE+ power mode, you have the first e-bike that does not need to be recharged! Helping when you need it and recharging the battery where your body can deliver it, BIKE+ technology seamlessly optimize your efficiency while riding, decreasing your effort by 30-40% (in an urban trip). It is the first non-plugin parallel hybrid bike.

WITH THE ADOPTION OF ZEHUS' ALL-IN-ONE HUB, WE BRING ITALIAN DESIGN AND SKILLED CRAFTMANSHIP TO ELECTRIC BIKES.
