Intelligent power delivery

The Ultra Intelligent Control System (ICS) is the culmination of five years of research and development. The ICS has a 6-Axis integrated accelerometer that senses gradients and braking to engage or reduce power delivery accordingly. Utilising an advanced power output algorithm, the ICS delivers safe, reliable and effective power assistance when it is needed most.

The Bluetooth PAS (Pedal Assist System) mounted on the crank arm detects when you are pedalling to provide appropriate power assistance (not included in the Ultra-XS Kit).

The Ultra App offers five programmed power delivery options that allow you to select the exact amount of power assistance that suits you most. You can choose to have none, some, or most of the work done for you.

Integrated technology

With Ultra Ebike, all sensors to brakes, throttles and pedals are wireless Bluetooth connected.

The battery is simply placed in a subtle ‘water-bottle’ type holder, where the gyro control system is also housed.

The ride range is up to 60km on one charge.

The wheel hub motor drive unit is a state-of-the-art high-torque digital brushless motor with a power rating of UK legal 250W.

The Ultra e-bike conversion kits are beautifully integrated, super-easy to install and keeps your bike looking and riding like the bike you love.

Ultra app interface

The whole system is controlled via the free Android and iOS compatible Ultra Ebike App, where user preferences for power assist levels can be precisely set.

The app provides the rider with real-time assist level, speed, distance, charge level, ride distances and temperature read-outs, and even features a ‘lock bike’ function which disables the wheel and sounds an alarm if the bike is ridden.

What’s in the box

The Ultra Ebike conversion kits come complete with everything you need to transform your bike into an e-bike; 250w Ultra powered wheel, battery & bracket with incorporated ICU, a new tyre and inner tube, battery charger, brake disc rotor, handlebar phone bracket, instruction booklet and either a PAS device (the original Ultra Ebike Kit) or a Bluetooth Throttle/Display (the Ultra Ebike-XS kit), and all the tools you need to upgrade your bike to Ultra e-power.
