the furthest i ride mine with any regularity (about once a week on the riverwalk) is about 15mls. i have a messenger type bag hanging on my main one, with maybe room for a small grocery bags worth of stuff. another has a rack, but i haven't finished the bike. all mine are bikes i made though (not from scratch, from other cut up bikes i mean), so i try to add some carrying capacity into the idea.
i just got the bag i want for this one off ebay this morning
same bike as the last pic. i'm just picking them out of my photobucket and didn't realise i has a pic with a bag on it
the one a made a rack for. it's only braced on one side so it won't hold a lot. another one or two projects should end up with racks too.
10-15...ish? some were never finished and some of the first tries left some to be desired. it's fun for me though, like rideable creativity.
harbor freight has their lowest price welder for sale periodicly for under $100. i've never done a complete bike with mine, but i'm getting better i think. the 29er cruiser i posted in the show your cruiser thread i stretched and tacked together at home, but just yesterday i decided finish up the welding at work. i know plenty of people do all the work with them and i'm meaning to get to that point myself eventually.
i wouldn't say i've ever built a burrito. there's a little more to them. i've got an idea in mind for one, but i'd say what i've built are just stretch cruisers.
