18 kg flywheel mass & front drive for smooth motion
The centerpiece of the H21 Pro is the massive flywheel mass of 18 kg. In combination with the front drive, it ensures an exceptionally smooth, uninterrupted motion. The result is a natural, fluid pedaling feel – smooth and quiet, whether for light endurance training or intense intervals.
Quiet magnetic brake system – efficient & gentle
The resistance is electronically controlled via a magnetic motor and can be easily adjusted on the workout computer. Combined with the belt drive, the ergometer achieves optimal concentricity where power is transmitted without loss of performance. This makes training extremely quiet and effective – ideal for apartments and multi-family homes.
15.6" touchscreen workout computer with every workout mode
The 15.6" touchscreen workout computer is the control center of your training: it clearly displays speed, cadence, distance, time, watts, calorie consumption and heart rate. Right on the device you choose between manual mode with your own target for time, distance, calories or heart rate, 12 workout programs, watt-constant ergometer mode (default 125 W – the power output stays the same no matter how fast you pedal) and target heart rate at 55 %, 75 % or 90 % of your maximum heart rate – if your pulse stays above the target for 30 seconds, the console stops on its own. After training, the recovery heart rate measurement runs for 60 seconds and gives you a fitness grade from F1 to F6. Resistance can be adjusted across 16 levels, and four user profiles store name, age, height, weight and gender. For virtual rides, Kinomap is available on the console. A USB port with charging function as well as a smartphone and tablet holder are also integrated. Please note that we have no influence on the availability, compatibility and updates of third-party services such as Kinomap.
12 workout programs & precise heart rate measurement
A total of 12 programs – 4 each for beginners, advanced users, and pros – cover all needs from beginners to professional athletes. For heart-rate-based training, the H21 Pro measures your pulse via hand pulse sensors and an integrated receiver for chest straps; wireless pulse measurement is also possible via Bluetooth. A Polar T34 chest strap is already included in the scope of delivery.
Integrated sound system for extra motivation
The built-in speakers with bass system play the sound of your workout directly on the device – your Kinomap route, for example, with no annoying headphones required. You adjust the volume in the console settings.
Joint-friendly endurance training
The smooth, impact-free pedalling motion puts very little strain on knees and hips. Resistance can be dialled in finely from level 1, the low 45 cm step-through makes getting on and off easy, and seat and handlebar adjust to almost any body height. The H21 Pro is a home trainer, not a medical training device – please discuss with your doctor whether and how to train after an injury or illness. Seat and handlebar adjust precisely – for an ergonomic, joint-friendly workout.
Take-To-Carry system – space-saving storage
Thanks to the Take-To-Carry system with integrated transportation wheels, you can effortlessly move the ergometer through your home by lifting the rear and store it easily wherever you want. This allows the H21 Pro to adapt flexibly to changing workout spaces, taking up minimal space after your workout.
