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 S1 ist ein einfaches Speedbike mit App-Anschluss: 13 kg Schwungmasse sorgen ab etwa 60 U/min für einen runden Tritt, Zwift und Kinomap empfangen das Tempo. Den Widerstand stellst du aber per Drehknopf ein, Watt und Trittfrequenz fehlen. Der größte Haken: Die Sitzposition passt nur bis etwa 180 cm, im Wiegetritt zeigen Sattel und Lenker Spiel.
Pros
- Bluetooth-Anbindung an Zwift und Kinomap, Verbindung in Tests stabil
- Gleichmäßiger Rundlauf ab etwa 60 U/min dank 13 kg Schwungmasse
- Hoher Maximalwiderstand, Notbremse per Knopfdruck
- Wartungsarmer Riemenantrieb ohne Schmieren
- Nur 98 x 48 cm Stellfläche, Transportrollen vorne
- Aufbau allein in rund 45 min
Cons
- Sitzposition trotz Angabe von 190 cm nur bis etwa 180 cm passend
- Keine Wattanzeige und keine Trittfrequenz am unbeleuchteten Display
- Apps können den Widerstand nicht steuern, Watt nur geschätzt
- Spiel in Sattel und Lenker im harten Wiegetritt
- Hörbares Reibgeräusch, Filzbelag verschleißt
