Frame
The structural parts of the Brema model, main frame, rear frame and front fork are are made of magnesium alloy. This is a material that gathers excellent qualities of strength and lightness for the bike structure elements. The main frame and rear fork connection sets an articulation mechanism up which allows the rear wheel suspension device showing a high efficient performance.
Folding system
The Brema model's folding system is intuitive, easy and fast.
The folding points, where the fasten mechanisms and structure discontinuities are, are built with aluminum elements to guarantee the necessary solidity.
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 Brema model is equipped with a 36V LG lithium battery with a 10,4Ah, optionally 14Ah of charge capacity, giving it a riding range of up to 110 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 and 250W motor
The Brema 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 hydraulic disc brakes
The Brema is equipped with 160 mm hydraulic 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.
7-speed transmission
The Brema's 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.
Full suspension with front fork and rear monoblock element
The front fork is fitted with a telescopic air suspension element with adjustable stiffness. Meanwhile, the connection between the rear frame and the main frame consists of a hinged joint at the bottom and a monoblock-type spring suspension element at the top.
Both suspension systems help absorb the movements and vibrations caused by irregularities in the terrain, allowing for comfortable riding on paths and trails beyond paved roads.
Color LCD multifunction display
The Brema is equipped with a backlit display that features clear, easy-to-read graphics. It displays the data needed to monitor all riding parameters. It indicates real-time speed, lap time, distance travelled, remaining battery, motor assistance level and provides access to other functions such as the headlights and settings menu. The display is also equipped with a USB port to charge other devices such as mobile phones, smart watches and tablets. For a safe management and not having to release the handlebar while handling the device, the display buttons are set close to the left grip.
