The turbo has long been a staple of winter training routines but indoor cycling is now more enjoyable, effective and realistic than ever, thanks to the growing popularity of the best smart trainers and training apps. The latest generation of indoor bikes takes that up a notch.

If you’re growing to love cycling in the great indoors, whether that’s to beat bad weather or make the most of limited time, a smart bike provides a dedicated training setup designed for the task in hand.

Unlike the turbo, a smart bike packages up everything you need to ride indoors in one bundle. You don’t need to worry about using your carbon fibre bike on the turbo trainer, nor do you need to be concerned about the increased wear and tear of expensive components.

On the flip side, smart bikes are a significant investment and require space for a dedicated pain cave.

Here’s BikeRadar’s pick of the indoor bikes we’ve tested, plus our buyer’s guide on what to look for if you’re thinking about splashing out on smart bike.

  • £1,899 as tested
  • Easy to set up and adjust with good connectivity
  • Lots of metrics and plenty of training routines available from Wattbike

The Wattbike Atom is easy to set up and get connected to your computer, tablet (for which there’s integrated support) or smartphone, as well as third-party indoor training apps, including Zwift. There are plenty of training routines available in the accompanying Wattbike app, too.

It’s easy to change saddle height, handlebar height and a number of bike fit adjustments, but crank length is fixed at 170mm. Although it’s heavy, you can roll the Atom around on its small front wheels.

With a chain drive for the resistance unit, there’s an outdoor bike feel to the Atom, although that does generate a bit more noise than its competitors. The drop handlebar at the front mimics the setup of a road bike but, with 22 sequential gears, set ratios and no brake levers, that’s where the comparison ends.

The Atom generates loads of data on power output, pedalling smoothness and other metrics, although when doing HIIT sessions, we found the lag when changing resistance sometimes made for awkward transitions.
