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 Training Bike 300 ist ein leises Rad für ruhiges Ausdauertraining: Riemen und Magnetbremse arbeiten fast geräuschlos, ein Motor schaltet die 24 Stufen schnell um. Der Haken liegt in der Elektronik: Zwift wird nicht offiziell unterstützt, Kinomap regelt keinen Widerstand, und das Display springt alle 3 s weiter. Mit 6 kg Schwungmasse und hartem Sattel taugt es aus unserer Sicht eher für moderates Training als für Sprints oder App-Pläne.
Pros
- Sehr leiser Lauf durch Riemen und Magnetbremse
- 24 Widerstandsstufen, per Motor schnell umgeschaltet
- Wartungsarm, da ohne verschleißende Reibbeläge
- Kombipedale für SPD-Schuhe und normale Sportschuhe
- Bluetooth FTMS sendet Daten an Kinomap
Cons
- Zwift nicht offiziell unterstützt, Zusammenspiel scheitert in Erfahrungsberichten
- Konsole stürzt vereinzelt ab, sobald eine App den Widerstand ansteuert
- Display wechselt alle 3 s, kein Wert lässt sich festhalten
- Sattel hart und weit vom Lenker, Lenker nur höhenverstellbar
- Leichte 6-kg-Schwungscheibe, Tritt bei niedriger Kadenz weniger rund
Das JASPORT A3 ist ein einfaches Indoor Bike, das per Bluetooth Tempo und Trittfrequenz an Zwift und Kinomap sendet. Aus unserer Sicht taugt es nur für lockere Ausdauerfahrten mit App. Die Filzbremse lässt sich kaum dosieren, das 7,5 kg leichte Schwungrad läuft unrund, und im Wiegetritt wackelt der Rahmen. Wenn du Spinning, Sprints oder Training nach Watt planst, ist es das falsche Gerät.
Pros
- Sendet Tempo und Trittfrequenz per Bluetooth an Zwift, Kinomap und Yesoul
- Leiser Riemenantrieb bei mittlerem Widerstand, wartungsarm
- 24 kg leicht, mit Transportrollen allein verschiebbar
- Sattel in Höhe und Länge verstellbar, Sattel und Pedale tauschbar
- Aufbau in rund 35 min allein, bebilderte Anleitung
Cons
- Filzbremse kaum fein dosierbar, Vierteldrehung reicht fast bis zum Stillstand
- Schwungrad mit 7,5 kg, Tritt unrund, Scheibe eierte im Test
- Rahmen, Lenker und Sattelhalterung wackeln im Wiegetritt
- Keine Wattanzeige, Widerstand per App nicht steuerbar
- Bei hoher Last laute Schleifgeräusche und Geruch nach verbranntem Filz
