    pizza delivery bicycle

    I would like to build a pizza delivery bicycle from scratch I have built bicycles in the past but I have never built one from scratch I have always cut up other bikes to use parts off them to build something cool.

    I think the only problem I am going to run into is the size of the head tube.

    Dose anybody know what the mesuerements would be for these bikes and what size tubing I will need?

    I am 5'7 I am planing on useing bmx parts to build it must go fast I am going to have a 24'' single speed free wheel on the back with a 20'' front wheel and a one piece bmx crank and bottom bracket.

    Here's a guy who's has done it a few times Alex Wetmore is always busy with something? Cycle Truck just check out everything that has to do with "cycle truck" and you'll have a really good idea of what's involved as well as some excellent pointers on design.

    if you want fast, use gears, and a crank with bigger rings than what can be had with a bmx crank. For a bike to be fast in travel, it has to be able to maintain a quick pace.
    The speed is break neck, faster than a high speed dual cassette tape deck.

    Are you going a few blocks or a few miles? If I was doing this I would keep the bmx stuff for the shortest deliveries, and convert an old steel road bike (with a nice set of wheels) from the 1990s to a flat handlebar bike and use that for longer/multiple deliveries.

    BMX gearing doesn't seem like it would be a problem to me. 44x15 with a (407-44)-ish rear tire should be workable. It's about 67 GI, which will be OK for a bike of the weight I'd guess this is gonna be.

    Head tube length would depend on how high you'd like your bars. You could grab a BMX fork and cut off the threaded bit, then weld a long steerer to that (maybe from a cheap olde 25" Raleigh Sports clone).

    get out a big sheet of paper 20" front 26" rear perhaps bodge up an old cruiser frame clone

    machine a head tube extension ..[time to buy a Lathe)

    Load to be heavy, up front ? maybe a low trail will be good .

    My bike friday is low trail works well [pannier rack carries the load,
    I can carry pizza boxes home under a stretch net hooked into D rings on the pannier lid.]

    While I haven't ridden the bike, I've been told by a guy who makes deliveries on one of these that they work very well. The downtube extends forward from the headtube and supports the load without having to deal with a flopping fork.

    those are the best ones, unless you like the cargo tossing you in a turn like an angry girlfriend.

    I have been looking into gearing I love single speed with free wheel or coaster brake a 52T front chain ring with a 16T or a 14T free wheel would give me the gearing I would be looking for.

    I am still trying to figure out what tube thickness I need for the tubeing any help woul be great.
