Hey All, Is it normal when not using the motor or when coasting to feel like you are slowing down way too fast? I hear something rubbing when I just walk the bike but can't see anything obvious. Maybe the disc brake isn't centered enough on the front tire? Anyone else have this issue? It's such a beast to pedal without the motor. BTW, I own the Aventure 2. Just bought it last week. I love the bike except for that.
