    Infineum Extreme Electric Mountain Bike

    An entirely British concept and design, the Infineum Extreme Electric Mountain Bike. With it's rugged outdoor looks ably complemented by a powerful, yet lightweight, motor which is driven by a unique patented stackable Lithium Polymer battery system. This provides the bike with an unrivalled performance.

    Battery Technology

    The Extreme Electric Bike like all Infineum bikes use a Patented Stackable Battery System

    The Motor

    The Epicycle Friction drive motor weighs only 1.82Kg and is situated in the front wheel hub, making it easier to remove than the usual rear position, where gears may get in the way. The lightweight technology gives 200 watts of pure power, ensuring perfect balance for an effortless and enjoyable journey

    Modular Connectors

    Modular connectors allow the components to be attached to a central wiring loom, which is housed and hidden inside the frame. This offers an aerodynamic, streamlined, aesthetically pleasing design as well as protection from the elements. Consequently, servicing is made as easy as possible, giving the rider the ability to simply unplug the components at source.


    High quality branded components such as Shimano Alivio gears and Rock Shox shock absorbers enhance the performance and ride experience of the Infineum Extreme. 24 gears operated by Rapidfire trigger gear shifters and quality V-brakes make the Extreme ideal for both recreational and conventional cycling.

    Really pleased with my choice!
    I did my research on electric bikes before settling on the Infineum Extreme. I booked a test ride with Matt on the phone and had a go on quite a few other bikes.

    Extremely happy and will be recommending to my friends!
