If any of you members can help me I would greatly appreciate it. My wife has a first edition Aventon Pace 500, and likes the bike well except for the behavior when under power. She feels that any setting is too abrupt on take off, and she needs an assist setting that is less than level 2. She rarely uses any power, which is great, but I think she would use it more if it was more intuitive. Suggestions?
