Form factorBasic design according to the manufacturer: upright, semi-recumbent with backrest, or folding X-bike
Upright

Resistance systemType of brake and how it is adjusted: magnetic via rotary knob (manual), magnetic via console (motorized) or induction for the finest gradation. Manufacturers also call induction ECB, eddy current or electromagnetic brake – even when “magnetic brake” is in the name; the motorized magnet is also called SMR or digital resistance. If the resistance adjusts itself during a workout (auto resistance, auto-follow, control via app), the adjustment is motorized – never “Magnetic, manual”.

Verdict
Pros & cons
Der Hammer Cardio XT6 BT ist ein echtes Ergometer mit Wattsteuerung von 10 bis 350 W, dessen Widerstand Kinomap und Zwift automatisch regeln. Wenn du als Einsteiger, Senior oder in der Reha allein trainierst, passt er dank tiefem Einstieg und leisem Lauf gut. Der Haken: Die Wattanzeige lag im Test rund 10 % zu hoch, und ein Speicher für mehrere Nutzer fehlt.
Pros
- Drehzahlunabhängige Wattsteuerung von 10 bis 350 W
- Kinomap und Zwift regeln den Widerstand automatisch, ohne Abo
- Tiefer Einstieg erleichtert das Aufsteigen bei steifer Hüfte
- Leiser Lauf mit 40 bis 42 dB im Test
- Runder Tritt bis zur Höchstlast dank 8 kg Schwungmasse
- Sattel in Höhe und Länge verstellbar
Cons
- Wattanzeige im Test 7 bis 11 % zu hoch
- Kein Speicher für mehrere Nutzer, Daten vor jedem Pulsprogramm neu eingeben
- Puls ab Werk nur über Handsensoren, Brustgurt liegt nicht bei
- Lenker nur in der Neigung verstellbar
- Vereinzelt Knackgeräusche beim Treten beschrieben
Der ProForm 225 CSX ist ein aufrechter Heimtrainer mit motorischer Magnetbremse und 20 Stufen, die du bequem per Taste wählst. Für Einsteiger, die gern nach Video fahren, ist er ein stimmiges Paket mit iFit: Im Kurs passt sich der Widerstand automatisch an. Der Haken: Ohne Abo bleibt ein gewöhnlicher Heimtrainer, die Watt sind nur geschätzt, eine Pulsmessung nennt der Hersteller nicht.
Pros
- Motorische Magnetbremse mit 20 Stufen in Einerschritten, per Taste verstellt
- Widerstand passt sich im iFit-Kurs per SmartAdjust automatisch an
- Sattel in Höhe und Länge verstellbar, auch für zwei Nutzer
- Kompakte Stellfläche von 89,2 x 53,9 cm fürs Arbeitszimmer
- Ventilator, Lautsprecher, USB-C-Buchse und Tablet-Halter an Bord
- Laut Hersteller für Nutzer bis 125 kg zugelassen
Cons
- Automatik und Kurse nur mit kostenpflichtigem iFit-Abo und WLAN
- Wattwerte nur geschätzt, keine drehzahlunabhängige Ergometer-Steuerung
- Keine Pulsmessung in den Herstellerangaben
- Wattbereich und Schwungmasse nicht angegeben
- Steuerung durch Zwift oder Kinomap nicht belegt
