The SB20 is an extremely solid smart bike that is great fun. The driving experience in particular is much better than what I was used to from the smart trainers. The buttons alone are a bit small and the switching process is virtually free of feedback. In addition, due to the high flywheel mass, the ERG mode is not as responsive as with roller trainers.

Das SB20 ist ein enorm solides Smart Bike, das viel Spaß macht. Insbesondere das Fahrgefühl ist wesentlich besser, als ich es von den Smart Trainern gewohnt war. Allein die Schaltknöpfe sind ein bischen klein und der Schaltprozess quasi rückmeldungsfrei. Zudem ist aufgrund der hohen Schwungradmasse der ERG Modus nicht so reaktionsschnell, wie bei Rollentrainern.
