Resistance systemBraking principle according to the manufacturer: magnetic (contactless, quiet), friction (felt or leather brake on the flywheel) or electromagnetic with motorized adjustment. Manufacturers also call the electromagnetic brake ECB or eddy current brake. If a motor adjusts the resistance – it adapts itself during a workout (auto resistance, auto-follow, control via app) –, this counts as “Electromagnetic (motorized)”, even if the manufacturer only speaks of a magnetic brake; “Magnetic brake” means adjustment via knob or lever.

Verdict
Pros & cons
Das Domyos Challenge Bike ist ein schweres Indoor Bike mit elektromagnetischer Bremse, die Zwift, Rouvy und Kinomap über offenes Bluetooth FTMS selbst steuern. Damit bekommst du echten ERG-Modus ohne Smart-Bike-Aufpreis. In Tests lag die Sollleistung nach rund 5 Sekunden an, und das Rad bleibt leise und ruhig im Wiegetritt. Der Haken: Sattelklemmung kippelt, Neigung grob gerastet. Außerdem wirkt die hauseigene App unfertig.
Pros
- Zwift, Rouvy und Kinomap steuern den Widerstand automatisch per FTMS
- ERG-Sollleistung in Tests nach rund 5 Sekunden erreicht
- Rund 60 kg Eigengewicht, ruhig im Wiegetritt und Sprint
- Sehr leiser Lauf durch Magnetbremse und Riemen
- Kein Hersteller-Abo nötig, offen für jede FTMS-App
- Ersatzteile laut Hersteller mindestens 10 Jahre lieferbar
Cons
- Sattelklemmung kippelte in Tests, auch nach dem Tausch
- Sattelneigung rastet nur in groben Winkelschritten
- Hersteller-App E-Connected unübersichtlich und schlecht abgestimmt
- USB-Anschluss zu schwach, um große Tablets geladen zu halten
- Nicht klappbar, rund 60 kg schwer zu verschieben
Das NordicTrack X24 Bike ist ein Indoor Bike mit neigbarem Rahmen bis 20 % Steigung, das gefilmte Strecken leise und mit realistischem Fahrgefühl nachfährt. Es taugt für dich, wenn du iFIT Pro dauerhaft einplanst und einen festen Stellplatz hast. Der Haken: Ohne Abo bleibt vom 24-Zoll-Touchscreen kaum mehr als der manuelle Modus, und Zwift ist nicht belegt.
Pros
- Rahmen neigt sich von 10 % Gefälle bis 20 % Steigung, mit iFIT automatisch
- Magnetbremse und Riemen laufen in Tests sehr leise
- 24 fein abgestufte Widerstandsstufen, auch für harte Einheiten ausreichend
- Q-Faktor von 15 cm wie am Straßenrad
- Schwenkbarer 24-Zoll-Touchscreen auch für Kraftübungen neben dem Rad
- Belastbar bis 159 kg laut Hersteller
Cons
- Automatik, Kurse und Streaming nur mit iFIT-Pro-Abo
- Keine belegte Kopplung mit Zwift oder anderen offenen Apps
- Wattanzeige weicht in einem Test um bis zu 10 % ab
- Sattel in mehreren Tests zu hart
- 93 kg schwer, Lenker nur in der Höhe verstellbar
