I'm wondering if any of you have a suggestion as to where I would find a bag for my Dahon 3-speed. The bag probably shouldn't be made for a bike. It's a regular 20inch-wheel folder, and I'd use the bag to take the bike on greyhound-type buses. Durable is good, but I'm a poor student and I'd be protecting a bike I bought for $120 and that's a 20th of what some of you paid for your bikes... any bag that costs more than I paid for the bike is automatically out.
I'm thinking about sewing a regular tarp up somehow so it'll cover the bike, but maybe there's an easier solution i haven't thought of.
