Powerful, lightning fast and designed for city life, at just 39.7lbs the Voya E+ is our lightest ever commuter e-bike. It might look like a regular bike, but it's anything but. With a slim, integrated battery and small but mighty 3.7lbs hub motor, the Voya E+ will take your commute to the next level. Its intuitive one-button controller on the top tube makes selecting assist mode, changing modes and checking your battery totally hassle-free. The ultimate lightweight electric commuter bike that makes hills a breeze, and leaves gas in the tank for a full day in the office, is the only way to get to work this year.

SyncDrive Move

Powerful SyncDrive Move rear hub motor, with 25Nm of torque, is designed for all urban terrain and hits speeds of up to 20mph with minimal pedal effort.

Smart Assist

Our Smart Assist function uses 4 sensors to factor in ride speed and pedal power to automatically deliver seamless support from the motor as you pedal.

Powerful Battery

Developed in partnership with Panasonic, the powerful EnergyPak 250 lithium ion battery is slim enough to stylishly conceal in the frame. The 4A charger guarantees lightning recharge in 3.4 hours, with an 80% charge achieved in just over two hours, and when fully charged, the battery offers 250 watt hours and up to 45 miles* (72 km).

Disc Brakes

Hydraulic disc brakes provide reliable and stable brake control power and are easy to maintain for daily commutes.

One Button Controller

The one-button RideControl Go controller on the top tube makes it easy to activate assist mode; select from 4 ride modes and check the battery power status.


The lightest E-bike in the lineup just 39,7lbs (18kg) –you can ride it easily even without pedal assistance.
