Custom built for the Oregon Manifest Contest. Made to use the stokemonkey motor and the xtracycle system of bags, etc. For a cargo bike, I love this thinking. Check it out...

Small wheels are strong, light (all else equal to bigger wheels), convenient to park and store, and they offer gearing benefits to e-bikers. But there is no getting around the fact that every small increment downwards in wheel diameter yields a much larger reduction in ride quality. 27" wheels can be pretty awful and still ride relatively nicely. 20" wheels can be top quality and still ride relatively poorly.

20 inch wheels are what I have settled on when strength and low axle height were paramount, but ride quality had some value.

The Madsen cargo bike uses a 20" rear wheel with a 26" front wheel, to reap some benefits of both sizes.

Voicecoils - the photo on the bottom, when you say "custom frame" do you mean it is totally custom, or can it be bought somewhere? That is a really interesting looking frame to me, curious if it can be bought or where it came from.

Actually, custom is the wrong word... it was a production bike but sadly just 2 were made! :lol:

You can see a whole bunch of construction photos here: http://www.moz.geek.nz/mozbike/build/binbike/

One lives in Canberra now, if you ever want to check it out in person I'll let Jeremy know. It really was a great design, never intended to be electric but plenty of space for all sorts of drive configurations. The other was sold last year by Maurice to a Sydney local.
 
vodid - thanks for the post. Very interesting design. I need to pay more attention to the Oregon Manifest bikes. For those that don't follow the link in the 1st post of this thread, here is picture of the bike:

Yea I really like that first bike. Is the stokemonkey a dd motor ? I thought it was no longer available as well.

Thanks for sharing.

The Xtravois 2.0 was built by Clever Cycles (manufacturer of Stokemonkey) for Clever Cycles. Todd (the proprietor) can still have a Stokemonkey setup whenever he wants one.

Working at an ebike/cargobike shop for the past two years. I have seen and used most configurations of cargo bike on the market, the Bullit made by larry vs harry is hands down the best I have ever used.

Nice bike. But judged only by cargo capacity, it's far from one of the best around. For some riders, an 8Freight. a big ol' bakfiets, or even a pedicab trike might be preferable because they can carry larger loads.

And of course, its riding characteristics can't touch those of a normal bike, while a Big Dummy or Xtracycle comes closer.

I think the Bullitt has a very good balance of features, though. If I had $3500 burning a hole in my pocket, I might get one for my wife. I was charmed by this customized version I ran across recently:

I disagree with that, IMHO It handles much better than a longtail, maybe beat only by the kona minute, which is a very short wheelbase long-ish tail bike. IMHO Its the best handling per weight/volume carried bike out there. After sampling all of the cargobikes we have had thru the shop, my boss sterling rides a bullit, the front counter guy nelson has one, and ill be building a home-brew 20" rear 20" front one shortly. They do have there disadvantages, they are heavier than a typical longtail of similar capacity for sure. plus, with a 26" rear wheel, its harder to make them electric. Plus, they are IMPOSSIBLE to grab in a bike stand, as the top tube is very thinwalled.

Put the clamp on the seatpost and let the front wheel sit on the ground.

I'll have to take your word for it about the handling. I've never ridden a linkage steered bike, a front loader, or a small-wheeled bike that rode nearly as well as the real thing. This one's all three, so it would have to be pretty ingenious to beat those odds.

My friend Jeremy (who builds front loaders as part of his living) points out that a $100 department store trailer will allow you to do almost anything a cargo bike can do, using the bike you already have. That's consistent with my own experience. I have some trailers in my fleet, including a couple I built that are much bigger than any cargo bike capacity-wise.

Here's Jeremy's cargo bike page:

Certainly there is some charm to cargo bikes, but they have already begun to seem a bit like the luxury SUVs of the bike world. (Probably because urban yoga moms are all over them like stink on poopy diapers.)

Based on my experiences so far with trailers of three types (two custom built and one Bell kid's trailer converted to flatbed), vs various ways of mounting cargo on regular bikes, vs my CrazyBike2, I'd have to say that for really big loads (several hundred pounds), the trailers generally "feel" safer and allow better riding on teh bike itself, even when pulling a trailer behind CrazyBike2. The smaller wheeled the trailers are, the better they carry stuff, becuse their load platforms are lowered--if I simply lowered the load platforms they'd probably ride better with bigger wheels, but that's one experiment I haven't tried.

CB2 itself can haul up to at least 300lbs or so of cargo, plus rider/etc., but depending on how it's loaded it can be a beast to ride and it si VERY hard on the rear wheels (gone thru a lot of them because of unavoidable potholes and too much load and no suspension). Up to 80-100lbs or so of cargo, and it's not so bad, especially if a third of that is up in front of the seat, below my legs in the middle triangle. Would probably be even better if the battery itself was in the front triangle or mounted to either side of it, but I haven't ever made up a mounting for that test yet. But overall, it's not an ideal cargo-hauler because of weight distribution. It does ride better than any other bike I've had or tried, even when those are loaded down with only 50lbs of stuff, vs CB2's 100lbs, but I can't say that any of them were a good or fun ride. :lol:

I have seen so many cargo bikes of various types and imagined putting my loads on them (usually stacks of big bags of dog food, sometimes just large collections of Freecycled items), and most of them would probably either not survive that very well (either frames aren't made for the loads I need to carry, or they don't have suspension and the wheels would break on our roads), or they would probably wallow, or otherwise not ride well.

I have been considering partially copying something like the Bullitt or one of the similar designs, but as a semi-recumbent and with suspension to deal with the unavoidable potholes in traffic here, rather than breaking wheels on them when heavily loaded. But before I build it, I wonder if someone who has a motorized or motor-assisted one or access to one would be willing to load it up with at least 7 or 8 large (30-40lb) bags of dog food, and see how it rides in traffic on marginal to decent flat roads at 20MPH, including having to stop and start a lot. I havent' seen anyone around here with anything even remotely similar. Probably, I'll just have to build it and see what happens.

Wait till there's millions of them everywhere and most are electric with many barely able to be pedaled. It's going to drive you crazy. AFAIC it will be great. :mrgreen:

Hey, as long as they're replacing big gluttonous polluting cars, I'm happy with that. At the moment, they seem to be replacing cheap versatile unpretentious cycle trailers-- which is neither laudable nor objectionable except as a matter of taste.

Fortunately, I have yet to come across a cargo bike that wasn't fully functional as a pedal machine.

A friend of mine just bought the juiced bike and is super happy with it.

This is one of my favorite production bikes right now...seems like a really great bike for the money.

Notice the double length 36v lithium battery :)

Cargo bikes vs trailers; my experience.

This is from my own practical experience of owning and using these two cargo systems only.

1. A bicycle pulling the B.O.B. brand single wheeled trailer.
2. A Surly Big Dummy longtail cargo bike.

Both move things you couldn't normally transport on a bike, and both are far better than just a set of panniers on a regular bike.

But I prefer the Big Dummy for practicality...here's why...

1. It's much shorter than a bicycle with a trailer...it's smaller.
2. You can walk it backwards without "jacknifing" a trailer rig...consider the reality of backing a trailer down stairs...that's a fairly normal thing that one does with a bicycle.
3. Locking...the trailer is pretty easy to unattach from the bike, and that's a good thing—but it also means you've gotta lock up the trailer, not just the bike frame.

As a negative for the Big Dummy, when you unleash the trailer from whatever bike you're riding, you've got your unencumbered bike, and it's back to its normal riding charectoristics. Also, you can attach the trailer to any of your bikes. And buying a trailer that you can add to your regular bike is a whole lot less expensive than buying a whole new bike.

I'm not attempting to dissuade/persuade anyone either way. They are both very useful ways to transport stuff. Either way, you'll be amazed at what you can transport, and it won't cost all that much in the larger picture of thing. Especially so if it allows you to get rid of a car, or one of your cars; insurance, upkeep, etc, etc.

Once you have any cargo system it starts to be fun when you see how useful it is, and how much you can transport with it that you never considered.
 
you can always hitch a trailer to your cargo bike if you really need to carry more than the bike can hold...
:wink:
