    According to his own description, he designed a bike around a rack which can carry "normal" bags.

    I would have just designed a different rack. But, what do I know.

    You can carry a ton on existing folding bikes...I wasn't even trying hard in this photo!

    Reminds me of this Japanese Bridgestone "Josis WGN".



    Seems to be marketed to housewives, I often see these parked outside the local supermarket - but if they change the design a bit, extend the frame and rack, it`d probably be capable of carrying a decent sized load.

    He did design the rack/basket specifically for the bike. I think the point he was trying to make was that any purse, briefcase, shopping bag, etc. would fit in the rear basket so that bike specific panniers would not be required for short errands. That is certainly not a revolutionary concept, but I think the design was executed pretty well. As with the Bridgestone posted above, the lower center of gravity from the 20 inch wheels makes for an easy to handle 'shopping' bike for a non-enthusiast rider. I would love to see more bikes like that here in the U.S.

    Might work in Sydney or Taipei, but not in a city that has snow. The pot holes that appeared in London roads over the winter means that my handbag or shopping would be bouncing out of that rack within minutes of setting off.

    And frankly, I wouldn't want an unsecured bag containing anything of value out of my sight in any city. A passing chancer could delicately remove it while I was waiting for the lights to change.

    Not too thrilled with the design. Rearward sloping rack -- will be interesting when someone uses bungee cords to try to carry any decent size load...

    Using an Xtracycle? You're using a non-folding R20 right? cuz I wonder if the folding joint would be strong enough

    And the integrated top tube gives it a classic/retro look and keeps it from looking like a BMX bike with a big rack. Also small wheels are stronger/hold more weight (if built for it)

    IMHO the Twenty's "hinge" is what gives it extraordinary strength compared to the typical "sideways-swing" type hinge as used on many folders. It works on the same principle as mounting 30ft street lamps on a relatively narrow threaded mounting base. A great deal of the stress is transfered as tension load on the bolts instead of a shear load on the hinge pivot of a vertical hinge.

    I'm certainly not an engineer but that's my take on the matter from experience in fabricating two wheeled vehicles.
    I plan on living forever... so far so good.

    I beleive the hinge joint will be strong enough. The rear section I plan to use is from a 20" suspension bike. Who knows when i will get around to it. Too many other bikes to tinker with.

    i love minivelos, but for me one of these does the job on any rack that fits a small wheel bike... don't wanna be a party pooper, but
    it aint the size of your wheels, its the rhythm of you cadence. And I got powergrips too.

    If its such a big "design flaw" why does Brompton's rack sit at a similar sloping angle? its just a frame that you fasten a basket to, or a trunk or panniers....none of these would "fall off" if properly installed/fastened to the rack. Look at a wheel barrel, it hauls stuff and its not flat, its sloping.....does this make it a flawed design?

    The first photo now shows a profile view with a basket... A wheelbarrow shaped basket. There's also another shot with a bag. Perfectly useful. But I don't think I noticed the polished wooden (extremely slippery) deck on that rear rack before, either. Some clear skate grip tape would go a long way toward saving that from form over function design miscue...

    The Brompton rear rack is a design flaw. It's made that way to keep the folding size small but as you can imagine, most people do not use it to carry anything. In fact, 95% of people use the front bag and attachment when carrying products. The reason people buy the rear rack on the Brompton is to attach larger wheels onto the rack so they can roll the bike like shopping cart. Very useful.

    ive seen dozens of Bromptons with trunkbags on racks here in L.A. What happens when you ride your Dahon up a steep hill? does your trunk bag fall off? Do you know how to tie a knot?

    I've never seen any Bromptons using a Trunkbag and this is New York City. I have a Brompton and a trankbag with interfere with the folding. Not the case with Dahon. The trunk bag on the Dahon works because the rack is level and the bike folds in half having no effect. I used this kind of bag for years on my Dahon but would never use on a Brompton.

    That's a pretty bike. But it's basically a fashionably retro-looking bike designed to look like it is addressing a problem that does not exist.

    Most people do not need to carry a "regular" bag around (whatever that is; I'm assuming he means a suitcase) very often...and certainly not on trips of less than 5km. What most people need on trips like that is the ability to carry groceries - and the basket he provides has such large holes that grocery bags would most likely fall through the holes in basket. Baskets (like Wald folding baskets) attached to the sides of a regular rack on a folder (or at least a BF) will give you much more functionality - and that would still allow you to strap a suitcase across the top of the rack if you needed to.

    And building a specific cargo bike without a front porteur rack large enough to carry a pizza on is just a wasted opportunity IMO.

    Loaded Moulton

    It's not a cargo bike but my Moulton TSR was carrying a big load on my recent ride through the Himalayas.
