I have no experience of a Roodog Bliss (just the sister ebikes - Striker and Avatar). However we have two Volt Metros and they are solid, reliable ebikes that easily cope with cycle paths. We got the bigger batteries. They also have a lever- not a throttle - that will take you up through the assistance settings without having to press the buttons. They are quite heavy ebikes - but they do feel very stable. Another company that provides really good after sales service.Roodog Bliss or Volt Metro ? any advice on both models would be appreciated please
