  10. 4iiii Fliiiight
    £479.99

    With almost silent operation and the ease of setup, the Fliiiight Smart Trainer raises the bar for your next sweat-inducing session on your favourite training app. The battery powered operation of Fliiiight’s zero contact induction technology means your workout can be anywhere, at any time. Its lightweight and sleek design makes it easily stored away to avoid clutter in your home.

    Real out of the box thinking from 4iiii. This is the only wheel on trainer which doesnt touch your wheel so you can use it with race tyres or tubs. You need to use an alloy rim or at least one with an alloy braking surface. There are strain guages built into the resistance mechanism so it is also a powermeter. This is also the only battery powered trainer so you can use it when warming up or on holiday or away on business. It folds flat for easy storage.

    Fliiiight can only be supplied to customers in the UK and  EU
