The Wattbike Atom is a smart indoor training bike from Nottingham-based Wattbike. It uses electromagnetic resistance and reports power to training apps. This page covers what Wattbike publishes about it, so you can judge whether it fits your budget and setup.
We have not ridden this bike. Everything below comes from the manufacturer’s own specification page, which we checked on 6 October 2026. The scores and head-to-head comparison that used to be on this page have been removed because nothing supported them.

What is the Wattbike Atom?
The Atom is Wattbike’s home smart bike. Wattbike’s page lists power accuracy of plus or minus 1% across a 0 to 2,500 watt range. Resistance is electromagnetic, so there is no friction brake to adjust.
It connects over ANT+, Bluetooth and FTMS. Wattbike says it works with Rouvy, Zwift and other leading training apps. You can read the full list on the Wattbike Atom product page.

Who it suits
Worth a look if:
- You train with power and want a bike that reports it accurately to Zwift, Rouvy or the free Hub app.
- You want to avoid a monthly fee for the bike’s own app.
- You want a rider-weight limit of 135 kg and a 2 year guarantee.
Think twice if:
- You ride once a week. At over £2,000 the cost only makes sense with regular use.
- You want a built-in screen and classes. The Atom needs your own tablet, phone or TV.
- You need to move it often. Wattbike lists it at 45 kg.
Bottom line
On paper the Atom is a serious training bike. The published accuracy, the free app and the open app support are its strongest points.
The price is the main hurdle. We cannot tell you how it feels to ride, so read owner and press reviews and compare it with the AtomX on Wattbike’s site before you spend this much.
