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 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
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
