What is the difference between an Atom and a Wattbike?

With the introduction of the Atom there is now a choice of two bikes to enhance your training. The decision of whether to purchase a Wattbike or an Atom is completely dependant on the type of training you are looking to complete, and how you are wanting the bike to perform.



- With the launch of ANT + and Bluetooth FE-C compatibility the Atom now offers unrivalled connectivity to several popular training applications such as Zwift and the Wattbike hub.

- FE-C technology now allows 3rd party applications to control the resistance automatically to simulate climbs and gradient changes.


- The Wattbike will continue to offer connectivity to 3rd party applications, although resistance changes will not occur automatically.

- Rides can still be recorded and uploaded through to popular training tools Strava and Training peaks.


The different methods of applying resistance to the Atom and the Wattbike is key in understanding which bike is suitable for you.


- The Atom utilises a step motor and dynamic resistance system.

- The step motor electronically controls the load on the flywheel and moves in discrete steps, controlled by the user, to affect the magnet position and control resistance.

- Resistance can now be adjusted through the use of shifters to simulate a real road bike change in gear.


- The Wattbike has two forms of resistance, Air and Magnetic.

- The air resistance allows for the most optimal road bike feel whilst using the bike. The nature of the lever allows for the application of immediate resistance. This simple and quick method of adjustment will allow a rider to instantly reach the desired resistance without any incremental steps in power output.

- The magnetic resistance simulates climbs and inclines through a magnetic column providing resistance against a flywheel. It allows access to very high-power outputs and low cadence sessions

Power Source


- The Atom will need to be plugged into a mains power source to be utilised, this is due to the internal step motor.


- The Wattbike can be run without a power source, the internal dynamo also charges the performance monitor whilst the bike is in use.

Head Unit


- The Atom does not come with a head unit as standard, all control must be run through a compatible smart device such as an iPhone or Android device able to run the Wattbike app.


- The Wattbike comes with its own Bluetooth compatible headset. This can be connected to your smart phone or tablet to run 3rd party application as well as the Wattbike hub.

- The monitor can assess and relay information on 40 different parameters in real time.

- The polar graph assists in finding the optimal technique for pedaling.

Heart Rate Belts


- The Wattbike can now be connected to Bluetooth Heart rate belts as well as ANT + and Polar coded.


- The Wattbike can be connected to ANT + and coded Polar heart rate belts. We have a choice on our website.

Types of Training


- The Atom has been designed for Cyclists, this is reflected by the types of training that can be completed on the bike.

- Steady state same resistance work is perfect for doing on the Atom through the use of the ergo mode, in which you can set a desired resistance and the bike will match your cadence accordingly.

- The incremental step motor allows for the simulation of hill workouts and steep climbs.

- Through FE-C compatibility the bike is able to adjust the resistance to match the set workout through the Wattbike app and other 3rd party applications.


The Wattbike is perfect for hitting precise power outputs through the use of the air resistance lever.

- Very low cadence sessions and strength work can be accessed through the use of the magnetic resistance.

- High intensity interval training is best performed on a Wattbike as it allows for an immediate change in resistance.
