Hi everyone. New commuter here. I am starting out with multi-modal, hopefully eventually getting to commuting all the way to work (about 25 or 30 miles). I bought my first set of panniers today to go on my rear rack, and will be taking the bus tomorrow. The bus has one of those front loading racks for your bike. the question I have is whether or not you should / could leave the panniers on the rear bike rack while it is loaded on the front of the bus (outside, obviously). will the panniers come off during the ride? They are not sturdiest panniers. Just a few velcro attachments and one strap on the bottom. It will be a pain to take them off before and after the bus, so I am trying to decide if the messenger bag is a better idea when going multimodal. Thanks, as always, for your assistance.
