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 8711 ist ein einfaches Einstiegsrad für gelegentliches Training mit Magnetbremse, 15 kg Schwungmasse und leisem Lauf bei mittlerem Widerstand. Wir halten es für brauchbar, wenn du bis etwa 1,83 m groß bist und keine App-Steuerung brauchst. Der Haken: Stachelpedale lösen sich mehrfach, der Lenker klemmt, und Bluetooth gibt es nur in bestimmten Ausführungen.
Pros
- Leiser Lauf bei geringem bis mittlerem Widerstand dank Magnetbremse und Riemen
- 15 kg Schwungmasse für runden Tritt bei lockerem Tempo
- Schneller Aufbau in rund 45 min, zu 70 % vormontiert
- Batteriebetrieb, keine Steckdose am Standort nötig
- 3 Jahre Garantie laut Datenblatt, Service liefert zügig Ersatzteile
- Sattel in Höhe und Länge verstellbar
Cons
- Stachelpedale lösen sich mehrfach während der Fahrt, teils mit Rost
- Lenker nur in der Höhe verstellbar und klemmt häufig in der Führung
- Ab etwa 1,83 m stehen Sattel und Lenker am oberen Anschlag
- Harter Seriensattel, schon nach 10 bis 15 min unbequem
- Keine Wattanzeige, Kalorien pauschal je Kurbelumdrehung gezählt
Der Wenoker JC308 ist ein leises Einstiegsrad ohne Stromanschluss, das Fahrdaten per Bluetooth FTMS an Zwift und Kinomap sendet. Für Ausdauer nach Gefühl reicht das. Der Haken: keine Watt-, Puls- oder Trittfrequenzanzeige, Kalorien und Tempo sind nur grob geschätzt, und den Widerstand stellst du immer von Hand ein. Wer nach Leistung trainieren will, ist hier falsch beraten.
Pros
- Sehr leiser Lauf dank Magnetbremse und Riemenantrieb
- Bluetooth FTMS sendet Fahrdaten an Zwift und Kinomap
- Kein Stromanschluss nötig, Monitor läuft mit zwei AA-Batterien
- Rahmen wird im Alltag mehrfach als stabil beschrieben
- Aufbau in rund 20 min mit beigelegtem Werkzeug
- Mit Transportrollen bei 27,2 kg leicht umzustellen
Cons
- Keine Watt-, Puls- oder Trittfrequenzanzeige
- Widerstand nur per Drehknopf, kein interaktives Training in Apps
- Kalorien und Tempo gelten in Erfahrungsberichten als deutlich zu hoch
- Lenker nur in der Höhe verstellbar, nur Körbe statt Klickpedale
- Sattel auf langen Fahrten teils als zu hart beschrieben
