Verdict
Pros & cons
Das Hammer AquaFold ist ein Wasser-Rudergerät mit Holzrahmen, das sich auf 79 cm Länge zusammenklappen und wegrollen lässt. Für mittelgroße Menschen bis 120 kg mit wenig Platz halten wir es für eine solide Wahl bei Platzmangel. Der Haken: Die Schiene misst nur 95 cm, Programme fehlen, und Kinomap empfängt nur Daten. Ein unabhängiger Fachtest liegt bisher nicht vor.
Pros
- Klappbar von 188 auf 79 cm Länge, mit Rollen verschiebbar
- Leiser Gurtzug ohne Ölpflege und ohne Kettenrasseln
- Bluetooth FTMS für Kinomap ohne Geräte-Abo
- Computer läuft mit Batterien, keine Steckdose nötig
- Laut Hersteller zu 99 % vormontiert geliefert
- Tankwasser hält laut Hersteller 1 bis 3 Jahre
Cons
- Schiene mit 95 cm für große Menschen zu kurz
- Belastbarkeit laut Hersteller nur 120 kg
- Keine Trainingsprogramme, nur Zielvorgaben für Zeit oder Distanz
- Niedriger Sitz mit 35 cm erschwert das Aufstehen
- Watt und Kalorien nur geschätzt, Genauigkeitsklasse C
Das Hammer Cobra XTR Plus II ist ein leises Magnet-Rudergerät für Einsteiger, das dank 118 cm langer Schiene auch Nutzern bis 200 cm genug Platz bietet. Der beleuchtete Computer hat viele Programme und Pulssteuerung per Brustgurt. Der Haken: kein Bluetooth, Kinomap nur per Kamera, und für ambitionierte Ruderer ist der Widerstand auf Dauer zu schwach.
Pros
- Sehr ruhiger Lauf durch Magnetbremse und Riemenzug, auch abends wohnungstauglich
- 118 cm lange Schiene, laut Hersteller für Nutzer bis 200 cm
- Beleuchteter, verstellbarer Computer mit laut Hersteller 20 Programmen
- Pulsgesteuertes Training mit Brustgurt und fünf Nutzerprofilen
- Klappbar mit Transportrollen, Aufbau in Tests in rund 30 Minuten
- Hammer-Workouts laut Hersteller ohne Abo nutzbar
Cons
- Kein Bluetooth, Kinomap nur über die Tablet-Kamera
- Widerstand für ambitionierte Ruderer zu schwach, untere Stufen sehr leicht
- Programm bricht nach 1000 Ruderschlägen ab
- Kunststoffpedale und Computerhalterung, die sich in Tests lockerte
- Schwacher Displaykontrast, keine Anzeige der 500-m-Zeit
