Wattbike Comparison guide
Trying to choose between the Wattbike Atom and the Wattbike Nucleus?
This useful guide will help you determine the right Wattbike for your training environment and goals you’re trying to achieve. Chosen by the best, all Wattbikes have unrivalled accuracy, reliability and rock solid stability to help you push your power targets. So, let’s dive in to each model to see which one will suit you and your training aspirations best.
Wattbike resistance explained
When it comes to Wattbikes, there are two different resistance types to train with - electromagnetic or air resistance.
To help you decide the best option for your training, the type of resistance you train with should be driven by your fitness goals, the type of training experience and environment you’re looking for. Let’s debunk our two resistance types for you:
ELECTROMAGNETIC RESISTANCE
Best for: Virtual training experiences, workouts, climbs and endurance sessions.
Electromagnetic resistance is determined by how much electric power flows through the magnets - so the higher the current, the higher the resistance. Our smart bike, Wattbike Atom has an electromagnet resistance which offers a power range of up to 2500W and 22 gears (when in ‘gear mode’). When in ‘ergo mode’, the electromagnet resistance can automatically adjust, so you can jump into any workout and the bike will take control of the resistance levels for you.
Air resistance
Best for: cross-functional training, interval sessions, customised workouts, off-feet training, weight management
Air resistance is determined by how much air is reaching the fan (by manually adjusting the lever on the side of the Wattbike). The more air you allow in and the faster you pedal, the more resistance you’ll have. Training with air allows you to have full control of the power load on your muscles, and reduces the impact of stress of running taking your training ‘off-feet’.
The trainer also has a manual magnetic resistance adjustment (by turning a dial on the Wattbike) which can be used in combination with the air, providing additional resistance for those more powerful sessions.
- Electromagnetic resistance offering a power range of up to 2500W with an high accuracy of +/-1%.
- Virtual indoor cycling experience that connects to a range of compatible training apps. Race friends in Zwift or ride real routes in Rouvy, the Atom automatically simulates gradients in the virtual worlds.
- Structured workouts and rides using our free Wattbike Hub training app.
- Ergo mode allows the smart bike to control the resistance changes for you, allowing you to focus on your training workout or pedalling technique with our unique industry measurement.
- Replicates your road bike set up with easy multipoint adjustment, dropped handlebars, a race saddle and gear shifters.
- Quiet riding with a small footprint, great looks and perfect for the home.
- Air resistance offering a power range of up to 2000W with an accuracy of +/-2%.
- All the same technology, accuracy, reliability and pedigree of our legendary air bike, but with an upgraded touchscreen that makes it perfect for cross-functional and hassle-free training.
