Pure Flux One resets expectations, recapturing the joy of cycling. Comfortable, lightweight and reliable, it delivers up to 25 mile / 40km assisted range. Carefully-designed around the innovative Gates Carbon Drive™ – a powerful, smooth rear hub motor for low-maintenance and much less mess with a convenient bottle-style battery system you can charge anywhere.


A to B Just Got Easier

Pure Flux One is the stripped back, built-to-last e-bike that gets you there, without a hitch. With a robust lightweight frame, 40km assisted range and durable Gates Carbon Drive™, it’s got everything you need to take on the road ahead. Enjoy the ride with the best value-for-money e-bike you’ll ever own.


The Easiest E-Bike Experience

Pure Flux One is the easiest e-bike you’ll ever ride. Powerful pedal assistance makes hills a doddle to climb and accelerating from lights faster – putting you ahead of the traffic. Meanwhile, the simple controls, comfortable ride position and familiar, classic design makes Flux One the e-bike that you’ll want to hop on time and again.


Comfortable Reliability

Come rain or shine, smooth roads or potholed lanes, Flux One is the mode of transport you can rely upon. Its aluminium frame is strong, durable and rust-resistant, it rides incredibly smoothly, with a rider position that maximises comfort without sacrificing efficiency or speed. In short, it’s the e-bike that you’ll want to ride day-in, day-out.


Powerful Assistance, Tuned to You

The 250W hub-drive motor delivers three uncomplicated power modes for powerful pedal assistance up to 15, 20 and 25km/h, enabling you easily tune your ride to suit you. Its seamless power transition and low resistance are hallmarks of outstanding quality – always there, but never holding you back.


Easy Charging, Ready To Go

Flux One’s battery is extensively tested and can deliver up to 40km / 25mi of assistance on a full charge. When you do want to top it up at home or at work, simply remove it from its unlockable housing and take it with you. It’ll charge up to 80% in just three hours (and fully charge in five), meaning you’ll be going again in no time.


Safe and in Control

Whatever the conditions, Flux One delivers control to your fingertips, coming equipped with powerful disc brakes. Compared to traditional rim-style brakes, disc brakes offer more reliable stopping power in wet weather. Combined with the comfortable handlebars, you’ll always be in control no matter the situation.


The Lightest E-Bike in its Class

Worried about your e-bike being too heavy? Pure Flux One is light enough to be nimble and fun to ride, and easy to carry when you need it. It strikes the optimum balance for an e-bike of its type, bucking the trend with a class-leading 17.5kg weight.


More Grip. Less Punctures

From broken glass to thorns and potholes, hazards can lurk behind every corner. But Pure Flux One tackles this head-on. Carefully chosen for their combination of durability, puncture resistance and grip without feeling like a drag on the road, Flux One is fitted with tyres from high performance specialists, Maxxis.


Stand Out and Be Seen

The Flux One has been designed to help you ride safer. The 360-degree reflective decals mean that you're easily seen by others, and the wheel rims also feature bright reflective markers to create a rotating visual cue to draw the observer’s eye.
