jhilden, Right, wrong or ”it depends”?
From the perspective of a non-technical user, an e-bike that is built and designed to use a motor will generally be superior to a regular bike turned into an e-bike with a conversion set.
At least in Finland conversion sets are fairly rare. Arguably there are obvious issues with the vendor lock-in that major brands like Bosch push on their users, but the reliability is okay and there are certified maintenance shops. #ebikes
