Infineum Extreme is the first electric bike from the new Infineum brand of high-end electric bikes. Based on an innovative British design the Infineum Extreme takes a major step forward in power assisted cycling with the longest ever continuous cycling distances, a result of the unique Infineum stackable LPX battery system.

The Infineum range brings a radical new concept in power-assisted-cycling by introducing for the first time a unique patented stackable battery system that multiplies the travel distance as extra batteries are added to stack on the dedicated rear rack. For long journeys between recharges the Infineum Extreme can accommodate extra batteries on the same rack, so greatly extended distance journeys become feasible, without stopping to change the batteries or recharge.

The Infineum Extreme is built for quality, incorporating quality components throughout, including Shimano Alivio gears and brake sets, Rock Shox shock absorbers and a Cane Creek headset. A back lit bicycle computer shows battery level and speed mph. The Extreme is based on a lightweight aluminium frame and weighs just 20kg including the battery.

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.

Shock Absorbers

The Rock Shox Dart 1 aluminium and steel forks with coil springs compliment the Shimano range to give a lightweight, comfortable journey.
