One of the largest multi-brand vendors in France released reliability statistics for the various EUC vendors and models, see https://store.urban360.com/2017/04/04/comparatif-mono-roues-electriques-gyroroues/ . They scored it from 1 (less reliable) to 10 (most reliable) based on their maintenance logs. Needless to say which brand trails behind, but what makes me worried is that the newest the model for Gotway, the less reliable it gets....
