Hello. Does anyone have a good recommendation for a bike bag that will work well on the rear rack of a Lectric XP 3? I've tried multiple bags, both with velcro attachments and the plastic clip-in fasteners. These "normal" size bike bags don't seem to want to work well because of the width of the bike rack. i.e. the plastic fasters of the clip-ins and the plastic loops in for the velcro types are positioned in such a way that the straps can't easily be tightened down without getting in the way of the rack and pulling the bag off center. Interestingly, Lectric doesn't sell a bag for the rear rack and I've not been able to find anything online that seems to work.
