Hving 4 Bosch powered bikes, I have a high degree of confidence that they are durable and I am not likely to have issues. In the case of the Delight I made my peace with not having a warranty on the motor in favor of having a snappy CX drive with no upper limit on assisted speed. It is fantastic with accurate speed info and support limited only by the gearing and how fast you can peddle. I later installed a Bikespeed RS on the motor inside the housing. It worked okay but it did so by tricking the speed sensor into recognizing every other rotation which resulted in halved speed readings.
As it had no warranty, I quickly added a badass box which is quick and easy to install without any tools or takiing anything apart. The Cube was purchased in February 2018 on ebay from a private seller. I have two bosch CX bike in the USA, one a 2017 Cube Touring Hybrid 500 and the other a 2018 Riese & Muller Delight.
