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 Sportstech SX175 ist ein leises, ordentlich verarbeitetes Einstiegs-Speedbike für Ausdauer- und Videotraining in der Wohnung. Der Tritt blieb in Tests trotz 4 kg Schwungmasse rund, der Sattel ist breit und bequem. Der Haken: höchstens 250 W bei 80 U/min, keine Watt- und Trittfrequenzanzeige, und Apps können den Widerstand nicht steuern. Wer nach Leistung trainiert, plant besser eine Klasse höher.
Pros
- Leiser Riemenantrieb, laut Hersteller rund 30 dB
- Runder Tritt bis zum Höchstwiderstand im Test
- Breiter, dick gepolsterter Sattel mit 18 cm Breite
- Bluetooth FTMS für Kinomap
- Flaschenhalter, Tablethalterung und Transportrollen ab Werk
- Einfache Bedienung per Drehknopf mit Notstopp
Cons
- Höchstwiderstand nur 180 bis 250 W je nach Trittfrequenz
- Keine Watt- und keine Trittfrequenzanzeige
- Apps können den Widerstand nicht steuern
- Lenker nur in der Höhe verstellbar
- Kundendienst nur per E-Mail und Chat, Antwort nach Tagen
Der Wenoker JC318 ist ein leises Einsteiger-Bike mit Magnetbremse und Riemen, das per Bluetooth FTMS Tempo und Trittfrequenz an Zwift oder Kinomap sendet. Für regelmäßiges Training in der Mietwohnung taugt er gut. Der Haken: Den Widerstand stellst du immer von Hand ein, Watt schätzt nur die App, und mehrfach wird ein verrutschender Sattel beschrieben.
Pros
- Magnetbremse und Riemen laufen leise und wartungsarm
- Bluetooth FTMS sendet Tempo und Trittfrequenz an Zwift und Kinomap
- Kein Abo für das Gerät nötig
- Rund 80 % vormontiert, Aufbau fällt leicht
- Transportrollen und integrierte Tablethalterung
Cons
- Sattel rutscht laut mehreren Berichten trotz Klemmung nach hinten
- Widerstand nur per Drehknopf, keine App-Steuerung oder Steigung
- Keine Wattmessung, Leistung in Apps nur geschätzt
- 27,2 kg leichter Rahmen federt bei Sprints im Stehen
- Nur Korbpedale, Lenker nur in der Höhe verstellbar
