Laptop bag for back of bike
I normally take my bike to the station to catch the train to work, and tie my bag on top of the luggage carrier. This means that the main force acting on a laptop in there would tend to try and bend the laptop, and I don't trust a laptop to stand up to that sort of abuse by itself. Especially since the streets and bike paths tend to be somewhat bumpy.
I am wondering if the hard sides in the Brain Cell will protect my laptop from bending forces and stand up to this type of pounding for an hour or so each day. I would use the Brain Cell inside another bag, so there is some extra padding.
Or should I give up on this idea, and look for some bags to attach to the sides of my luggage carrier?
Thanks in advance.
