Frame
The Nemausus is Q.ik's most compact model. It has a light, strong 6061 aluminium alloy frame. It has a tubular structure with a Z-shaped elliptical cross-section, with a cut-out and hinge in the middle. When unfolded, the bike is secured by a locking system that ensures a rigid and stable position for riding.
Folding system
The Nemausus model folding system is intuitive, easy and fast.
The folding system involves two steps. The first step involves rotating the front part of the frame 180° to position the front wheel parallel to the rear wheel. The second step involves folding the handlebar post and handlebars to sit alongside the wheels. To stabilise the bike when it's folded, it is necessary to lower the seat post until it touches the ground and becomes the third point of support.
A two-piece magnets device located on the axles of the front and rear wheels fix the folded position of the bike. It prevents the parts from moving while being manipulated or rolling on the pavements.
Battery
The Nemausus model is equipped with a 36V lithium battery with a 7,8Ah charge capacity, giving it a riding range of up to 50 km (according to the manufacturer). The battery fits neatly into the seat post, where the charging port and main power switch are also located. It can be easily removed, transported and charged anywhere without needing bike to be nearby.
The charging system features an innovative BMS, which prevents the battery from overcharging and overheating and regulates the release of energy for greater efficiency and longer use.
36V 250W motor
The Sora features a 36V, 250W motor located in the rear wheel, which is has a factory-set power limitation to stop the bike from exceeding 25 km/h. By law, when the bike reaches this speed, the motor must stop providing assistance. The motor is powerful enough to meet the demands of overcoming steep slopes.
A pedalling pressure Torque type sensor controls the motor assistance depending on which of the five levels has been chosen.
It has a clutch system that allows the bike to roll without any resistance should the rider want to cycle without any help from the motor.
160 mm Mechanical disk brakes
The Nemausus is equipped with 160 mm mechanical disc brakes on both the front and rear wheels. They offer great braking power and guarantee to stop the bike within a few metres in case of emergency in all riding conditions. In addition, squeezing the brakes automatically disables the motor, facilitating a more immediate brake response.
Shimano 7 speed gear
The Nemausus 7-speed transmission adjusts the pedalling effort without forcing the motor. The shift lever on the handlebars delivers accurate gear selection according to the gradient of the road. The derailleur is part of the Shimano 7-speed Tourney series.
Magnetic buckle
The Nemausus sets a magnetic device specifically designed to securely join the front fork and frame together when the bike is folded.
