Primo gen 4 is equipped with a brushless powerful and high-torque rear hub motor. For ultimate hill-climbing power, the motor torque has increased by 50% (To 60NM) from 40NM in gen 1. It comes in 250W (500W Unlocked) and 750W variants.

Primo Gen 4 has Shimano Altus 7-speed gears, replacing 3-speed in Gen 1. Shimano Altus has smooth, noiseless gear shifting. 7 gears provide a wide gear ratio for efficient riding.

Primo's premium ride experience relies heavily on braking experience. The Primo gen 4 features best-in-class Tektro HD-E352 hydraulic brakes with self-adjusting brake pads for maximum stopping power and easier usage compared to mechanical brakes.

Primo's 26" 2.15" Schwalbe Big Ben Puncture-Resistant premium German tyres are soft and comfortable, but also durable with a long life, making them ideal for riding on roads, gravel, or mild off-road tracks.

Primo Gen 4 has a range of 60-80km and an optional 48V 20AH battery, which increases the range to 170-200km. The battery balancer automatically switches to it when the primary battery dies.

Primo Gen 4 has Suntour front suspension forks with 10 cm travel (an upgrade from Gen 1's rigid forks). These suspension forks, along with soft and wide Schwalbe tyres, provide a very comfortable ride.

Primo has a throttle allowing riding without pedalling but is limited to 6 km/h for Australian laws. It's unlockable only for off-road use, ideal for maximum speed without significant pedalling on beaches or off-road.
