Monkey Link is a unique magnetic system that allows easy attachment of devices as well as their quick removal. This can be used for headlights, rear light and mudguards too. It is powered directly from the main battery and controlled from display
The frame is moulded in one piece from carbon fibre. This technique creates a frame that is exceptionally lightweight, yet incredibly strong and rigid. The carbon fibers are strategically layered and bonded with resin. Brake and shift cables, as well as hydraulic hoses, run through the inside of the frame. The thru-axle is a sturdy axle system used to attach the wheels to the frame and fork. A telescopic seatpost (commonly known as a dropper post) allows you to quickly adjust the height of the saddle while riding using a remote control on the handlebars or a lever.

Carbon fibre

The main advantage of e-bikes with a carbon frame is exceptional shock and vibration damping, they resist corrosion and wear very well and, compared to other materials, they excel in their low weight.
