    Big Dummy vs. Yuba Mundo frame sets

    A Big Dummy frame set retails for $950 where as a Yuba Mundo frame set retails for $550. Is the Big Dummy frame really that much better? What are you paying for besides name, marketing, etc?

    I've been riding (and loving) my Big Dummy for several years. Last year a friend of mine was looking to get a long tail cargo bike and asked the exact same question. Neither of us had seen a Yuba in person (nobody carries them in Hawaii), so I told her the things I read online that swayed me to pick the Big Dummy: frame weight, quality of components, frame geometry, frame material. In all aspects the big dummy is way ahead. In the end, price won out and my friend got the Yuba. She has been riding it for a year, and I can tell you that is is a fine bike - but the big dummy is much better. The yuba is HEAVY, and the front fork is nowhere near as strong as the Big Dummy. You don't notice it hauling kids or light loads - but throw an adult on the back and the fork flex will freak you out. Same goes for the brakes - the Yuba does not have disk brakes, and stopping can be terrifying with big loads. The components are cheap, and will need a lot of attention to keep them running smoothly. That said, if you are hauling light children on short trips, the yuba should be fine. I do feel that even though it is more expensive, the Big Dummy is a better value when you consider quality and long-term use.

    I agree with much of what Vantiki says about the Big Dummy pros, but wanted to point out that the Mundo frame is disc-ready and if you're building from the frame up, you can choose your components to be as high-quality as you please. As for the price difference, I attribute part of that to the QBP tax. So many of their bikes are 10-20% more expensive than they should be (IMHO). Not sure what your end use will be, but have you considered the Edgerunner? I don't know if they still offer it in frameset only, but it's the best longtail money can buy in my book, assuming general cargo bike duties.

    I find that the dummy is sportier, like a mountain bike and the Mundo is more like a city bike. I have ridden a Yuba with an (total 250lbs) adult and a child on the back, and it was very comfortable, but the upright position is clearly designed for those who like to take their time.
    Since the V3 Yuba frames, the Yuba is lighter than the Surly. I have not witnessed the flexing noted above and the one I have ridden extensively had disk brakes that were reasonably effective. I would rate the Yuba better for carrying heavy loads and the Surly better for general use.
    In short, if you are a mountain biker, you will want the Big Dummy.

    One big plus I'd put in the Mundo's corner is the Bread Basket. So much focus goes to the rear cargo on these bikes, but I really appreciate the front cargo that you can handle with the frame supported basket up there. The new Edgerunners will have a similar frame mounted rack system too.

    I was thinking of a frame up build, so both bikes would be built up with the same components.

    One thing I like about the BD is that the rear is built to the xtracycle dimensions, if I'm not mistaken. That means all the xtracycle accessories should fit. There is not one dominant standard in the longtail cargo bike world, but the closest thing to one is xtracycle. So a bike with those dimensions out back would be a plus to me.

    It's super easy to remove/replace the wideloaders, etc, on an xtracycle. Takes seconds.

    I agree with what a poster said above. The BD is probably a better bike more of the time. If you are hauling ultra heavy loads the majority of the time, I give the Mundo the nod.

    Since you're building either bike with equivalent components, the end result price will only basically be the difference in frame cost up front. So is a complete BD worth $400 more than a complete Mundo? Yes, I'd say so. You're basically paying half the difference in what the bikes cost new, complete. A bargain if you build yourself and only have a $400 difference.

    The Edgerunners look appealing to me. I don't know what a frame costs, assuming you can buy just a frame.

    I don't necessarily buy bikes for resale value, but it is one small factor to think about. Selling a BD later would probably be a piece of cake, and you'd likely get good coin for it. I think you'd have a more limited audience for a Mundo and hence get less out of it later and have less people responding to your CL ad. But just my off the cuff opinion there, have not done the research to be sure. I think a BD build would be more desirable in my neck of the woods, anyway.

    Thanks for this assessment. I looked around and saw somewhere selling the frame only for $900 (same as the Big Dummy). The Edgerunner looks very appealing to me! Honestly, I hated when Surly changed all of their bike designs to have the stupid top tube brace in ~2012. I loved the old Big Dummy Frame with the curved top tube. I'm wondering how the 20" rear wheel on the Edge Runner would fare - stronger, lower center of gravity, but not as good over bumps?

    I had a friend with a Madsen, and on my own CETMA, I find that the 20" wheel makes little difference except that it goes through bearings about twice as fast as the 26". The 20" rear wheel gives you lower gearing if you leave everything else alone. I like big apple tires for cargo bikes since they roll well, provide a little cushion, and can handle big loads.
    I have not ridden an edgerunner to give an opinion about it, but it looks like a good longtail option.

    I have about 700 miles on my Xtracycle Edgerunner and love it. Responding to your comment about the BD's straight top tube, the ER has the nice sloped one. Also, I find that the 20" rear wheel has no drawbacks and only positives. Mine has a BionX rear motor built into it and so the spokes are quite short and stout. The bike has had 450 pounds on it (my DW and two kids - all between 5'7 and 5'10) without issue. When you really load it up you start to think of how much is on that rear wheel.

    I do not know if the frame is stronger on the BD or ER, but the lower center of gravity with the 20" wheel has got to help, especially on starting up. Once you are moving at speed it probably has less affect. MSRP on the ER is about $1,500*. Your local dealer may be able to drop that a tad.?. That comes with disks and has decent quality components. I usually go with higher end stuff on my bikes, but have found these to operate flawlessly thus far. In other words, I don't think an extra $600 to the upgraded ER is worth it.

    If you add bags that is more $$.

    Pondering on an Xtracycle Edgerunner, with a Stoke Monkey Kit ... already have a 20" R'off wheel, they're super rugged in that size rim. .

    putting a crossover tandem road crank a chain tensioner
    and a 39-53 chainset would give a low climbing ratio , range and a Higher crusing the flat lands range too .

    got a 4 mile long bridge across the Columbia north with a steep corkscrew approach to get over the shipping channel on this end.

    and the Moved the Costco 7 miles away.. in the other direction West.

    Good on that 53 chainring, as my 48 x 13 spins too fast at 20 mph for a cargo bike (fine on the road bike). Also, the Stoke Monkey is recommended for hilly areas.

    Update on the Xtracycle vs. Big Dummy. I'm probably getting a Big Dummy to add to the heard. On weekends I go out to get on the Xtracycle and one of the 4 other family members has it, and returns near empty on the battery. So, I'm getting a good deal on the BD and will look forward to building that up. I still think the Xtracycle is a better design for hauling, but the Big Dummy should be fine. It'll get the same motor and hub and I will look forward to comparing them.

    An old thread, but thought I'd put in my $0.02. I have had my Big Dummy for a few years now. I love it and the kids love riding on it. While I have no regrets, if I were to buy today, I would go with a Yuba. It's just a better value for the money and does the exact same thing. Plus, the accessories are cheaper as well. The only advantage I see for the BD is the ability to take the rear racks off (for whatever reason you'd want them off...). The Yuba can carry more cargo as well.

    Either way, you'll get a nice bike. The Edgerunners look nice as well.
