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
Der DMASUN 8732B ist ein einfaches Speedbike mit Magnetbremse und Riemen, das im Test mit rund 35 dB im Sprint leise läuft. Für Fahrer bis etwa 1,80 m, die nach Gefühl trainieren, reicht das. Der Haken: kein Bluetooth, keine Wattanzeige, ein nur höhenverstellbarer Lenker und mehrfach Defekte am Widerstand – wir sehen hier ein Budget-Rad mit klaren Grenzen.
Pros
- Leise Magnetbremse mit Riemen, rund 35 dB im Sprint gemessen
- Runder Tritt auch bei Tempowechseln und Intervallen
- Ruhiger Stand im Wiegetritt bei normalem Körpergewicht
- Aufbau in rund 25 min, weitgehend vormontiert
- Batteriebetrieb ohne Steckdose, Tablethalter für rund 27 cm Diagonale
Cons
- Lenker nur höhenverstellbar, ab etwa 1,83 m zu niedrig
- Mehrfach berichtete Defekte an Widerstandsverstellung und Sensor
- Kein Bluetooth, keine Trittfrequenz- und keine Wattanzeige
- Grundwiderstand für untrainierte Einsteiger mehrfach zu hoch
- Sattel in Tests schon nach etwa 20 min unbequem
Das JASPORT C3 ist ein leises Speedbike für Einsteiger mit Riemen und Magnetbremse, das auf kleiner Fläche Platz findet. Für lockere Ausdauerfahrten reicht es, für Training nach Watt oder Zwift mit automatischem Widerstand taugt es nicht: Den Widerstand stellst du nur per Drehknopf ein, das Display zeigt bloß die Distanz. Der Haken: Geräusche nach wenigen Wochen werden mehrfach beschrieben, dazu ein unbequemer Sattel.
Pros
- Riemenantrieb und Magnetbremse, im Alltag meist leise
- Kompakte Stellfläche von 105 x 58 cm für kleine Wohnungen
- Sattel in Höhe und horizontal verstellbar
- Läuft mit Batterien, kein Stromkabel nötig
- Tablethalterung und Flaschenhalter integriert
- Aufbau mehrfach als einfach beschrieben, teils unter 10 Minuten
Cons
- Quietschen und Tretlagergeräusche mehrfach schon nach wenigen Wochen beschrieben
- Widerstand nur per Drehknopf, keine App kann ihn steuern
- Display zeigt nur die Distanz, alle anderen Werte nur per App
- Leichtes Schwungrad mit 7,5 kg, Tritt bei hoher Last weniger rund
- Sattel häufig als unbequem beschrieben, Lenker nur in der Höhe verstellbar
