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 Merach S38 ist ein leises Einsteiger-Indoor-Bike mit Magnetbremse, Riemen und offenem Bluetooth FTMS für Zwift und Kinomap. Er taugt für lockeres bis zügiges Ausdauertraining im Sitzen in hellhörigen Wohnungen. Der Haken: Der Widerstand beginnt bei über 100 W und regelt sprunghaft, Watt sind nur geschätzt, und bequem passt das Rad nur bis etwa 185 cm. Für Training nach Watt und viel Wiegetritt halten wir es für zu leicht und zu ungenau.
Pros
- Sehr leiser Betrieb durch Magnetbremse und Riemen, laut Hersteller unter 25 dB
- Offenes Bluetooth FTMS für Zwift, Kinomap und QZ
- Kostenlose Hersteller-App ohne Abo mit Kursen
- Guter Q-Faktor von 18 cm für gerade Kniestellung
- Im Sitzen trotz 6 kg Schwungmasse runder Tritt
- Knapp 30 kg und Transportrollen, leicht zu verschieben
Cons
- Grundwiderstand in Tests schon über etwa 100 W
- Drehknopf regelt nicht linear, Last springt nach einer Umdrehung
- Bequem nur bis etwa 185 cm statt der genannten 188 cm
- Rahmen gibt im Wiegetritt nach, einhändig leicht kippelig
- Unbeleuchtetes LCD ohne Stufen- und Wattanzeige, Watt nur geschätzt
Der YESOUL G1M Plus ist ein leises Fitness-Bike mit Großbildschirm: Auf den drehbaren 21,5-Zoll-Schirm spiegelst du per Kabel dein Handy, ohne Abo. Magnetbremse und Riemen laufen in Tests nahezu geräuschlos. Den Haken sehen wir beim Training nach Zahlen: Widerstand nur von Hand, keine Wattmessung, und mit 34 kg ist der Rahmen eher leicht für harte Sprints.
Pros
- Drehbarer 21,5-Zoll-Bildschirm in Full HD, auch für Training auf der Matte
- Handy per Kabel spiegeln, kostenlos und ohne Abo-Zwang
- In Tests nahezu geräuschlos dank Magnetbremse und Riemen
- Widerstand in 100 feinen Stufen, in Tests als präzise beschrieben
- Sattel in Höhe und Länge verstellbar, Polsterung in Tests gelobt
- Eingebaute 6-W-Lautsprecher mit klarer Sprachwiedergabe
Cons
- Widerstand nur manuell, Zwift und Kinomap regeln nichts nach
- Keine Wattmessung, Leistung in Apps nur geschätzt
- Mit 34 kg eher leicht, im kräftigen Wiegetritt wenig Reserve
- Haltegriffe nur in der Höhe verstellbar, eng bei langem Oberkörper
- Yesoul-App mit wenigen Trainingsplänen, mehrfach kritisiert
