Brand new version with LCD control panel for greater setup control and information, bigger 10AH battery for longer range and new water resistant wiring.

The Z4 is a top of the range electric MTB featuring front and rear adjustable suspension, easy folding aluminium frame with patented safety lock and 21 speed Shimano gearbox. This is a fully capable mountain bike with the benefit of being able to be folded up for convenient storage and transport. As the frame can be folded it allows the lithium battery to be stored inside keeping it safe and dry. During the week take advantage of the electric power system to nip around at a fraction of the cost of a car or motorbike and then at the weekend hit the trail for some off road fun. The 250W brushless motor has plenty of power and will push the bike to the maximum legal speed of 25KM/H making it totally road legal. Just select how much help you want from the electric system using the easy selector, start pealing and the motor will assist.

Other features include walk assist with finger throttle, digital control panel, kick stand, battery life indicator, bright front and rear LED lights, battery lock and rust resistant chain.
