I just took delivery of my new Aventure. My first impressions are that it's very very heavy but pedals easily. The build quality appears to be excellent. It rides like a dream and is smooth as glass. The shifters took a little bit of getting used to but function superbly. There is just a little bit of a lag when you start paddling before the motor kicks in but I quickly got used to that. My experience has only been on the pavement but I hope to get it off road very soon. All in all, the bike is bad to the bone.
