I disagree about a workbike not needing to fit as well as any other! I thought Xtracycle should make a integrated bike, too, and I floated my design as a candidate. Individual feedback was positive, but I guess the time wasn’t right. Takes a lot of capital to do a whole bike, and the cargo bike market in familiar parts of the world is, well, practically non-existent. Meanwhile, regular Xtracycles work awful good.

(though I’m not sure exactly how the relationship between the two companies is structured.)

Their response on their forums has been that they don’t want to make a wide variety of sizes, but I bet they would do very well with about 3–small, medium and large. It’s not as if a cargo bike needs to fit like a custom touring or racing bike.

I’m guessing they’ve seen your design…any reaction?

Stiffness actually a bit overkill with Xtravois, as it’s pretty heavy and rides like an empty schoolbus when not heavily loaded.

I haven’t ridden an Instigator/Xtracycle myself, but 2 people I’ve talked to who own them are very happy with the overall solid feel.

Try resizing your browser window and notice the image dimensions change. I think this coding technique confuses some browsers.

Also, I’m a great admirer of the xtravois. Imitation being the highest form of flattery, you should notice that my passenger’s handlebar borrows from your design (though it may not be too apparent in this photo).

I’m also curious how the xtravois’ lateral rigidity compares to that of an ordinary Free Radical-mountain bike combination? I find that mine is quite flexy. (This is also why I’d asked asked about the Instigator…)

I did make a point of linking the image to the place I found it, and referencing the image directly rather than making a copy. I try to do this whenever I “pinch” an image. Yours is one of the few good pictures of an Xtracycle with a passenger!

The Instigator is not mine, but that of a Stokemonkey prototype tester.

I was a little shocked to see my girls at the bottom of this post, what not having been asked for permission and all, but then I remembered that I’d posted it on a public forum, for one thing, and one with no means of contacting the poster at that.

So not that it matters, but yes, you may use it… 8-)

BTW, is that Instigator one of yours?
