For the ultimate indoor cycling experience.
The hassle-free option to indoor training.
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 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.
Best for: Virtual training experiences, workouts, climbs and endurance sessions.
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.
Best for: cross-functional training, interval sessions, customised workouts, off-feet training, weight management
