The eZee Primero heralds in the latest technology advances at eZeebike, the “T4”, the first eZee model to feature a torque sensing system. Coupled with an in-frame 36V 17Ah battery and the unbeatable eZee rear hub motor, this is one classy ride. The T4 torque sensing system features 8 levels of pedal assist as well as an independent throttle for power on demand.

The Primero’s heavy duty semi-integrated cargo rack holds up to 50kg and has a much larger carrying area than standard e-bikes. It also has an “easyfit window” inbuilt, allowing GMG and Yepp branded child seats to slot right in without any mounting hardware required. This rack can simultaneously carry a pair of pannier bags as well as a child of any age.

Effective braking, safety, and low maintenance are completed with German Magura hydraulic brakes featuring a motor cut-off safety function when the brake lever is actuated. With speed up to 34kmph these are brakes you will learn to trust. Add the latest tyre technology from German brand Schwalbe, the tough balloon-bike Big Ben Plus come with a Green Guard compound layer and reinforced side walls for puncture resistance. The 2” wide comfortable tyre will provide you with low rolling resistance for great road grip, protection and it’s durability will keep you comfortable throughout the seasons.
