Hi. I'm new to this e-bike world but have made some obversations from reading the online threads. My first observation is that there is a lot of confusion over performance and range. I think that that is probably less complicated for me in Europe as I like most other people here ride 25 km/h pedal assist bicycles not more powerful machines or those which rely on battery power for propulsion using a throttle. The range offered by any bike is very variable and is influenced by many factors including the motor power/batters size, rider weight, terrain, rider technique, fitness etc. As a newcomer I was amazed by the lack of range mentioned by other posters until I realised that many people use their bikes as electric motorcycles rather than power assisted bicycles. The second observation is the short life span of the transmission components experienced by many riders. Is that because too many manufacturers use components that are just not up to the job?
