An odd yet cool little trike

I've come across this rather odd little tricycle. It was donated to re-Cycles, and when it came in we stared at the rusty frame and noticed the missing parts and went "what the heck are we going to do with this?". So I took it home to assess what was needed, and decided it could be revived.

It's a bit of a mystery as to who actually made this thing, but more on that later. For now we look at photos!

Here's how it looked when it was donated:

Nice, eh? The interesting thing about this little beastie is that the front half of the frame tilts! The pivot for the tilting mechanism (situated on the axis of the two rear wheel axles) was quite seized up, and the rear drum brake was also stuck.

Here's the back end:

Oil was applied to the tilter in a few doses, and after a few days and some wrestling it eventually broke free.



The 16" drum brake wheel was replaced with an identical unit, as through a stroke of goofy luck I'd had one lying around for a few years. It had come from a similar trike whose owner had left its parts at re-Cycles while he took the frame home to repaint, and never came back (one reason re-Cycles had to adopt a policy against bikes or parts being left overnight) .

Yes, that is a Shimano 3-speed hub with extra-long axle. Both chains had to come off for a good scrubbing.

Here it is all apart, ready for some sanding and painting:

Since I was only painting with a spray can, I was not going to be anal retentive about making the finish perfect. I got most of the rust off, and the downtube is still a bit bumpy under the paint. I decided to go wit two strong colours, and settled on a dark green frame, with yellow fenders and chainguard. Of course I realize when I'm about to paint that those are also the factory colours for John Deere tractors...

So here is everything painted and awaiting reassembly:

The only original paint showing its robin's egg blue is the steerer tube, and a bit underneath the U-joint area.

And here's the assembled little beastie:

Yes, the entire front end tilts!

Halloween pumpkin and groceries fit nicely in the big Wald basket (it was missing its original one):

Now, back to the mystery. The head badge said "Sears" (of course the trike was not actually made by them), while the front fender flap says "Miyata". But there are no photos of a Miyata leaning trike to be found on the Net, outside of a few photos taken by my friend Richard of another local one here in Ottawa:


Note the design of the rear basket, as we'll refer to it later.

There IS a similar trike called the Bridgestone Picnica Wagon (and a newer Picnica that is a 2-wheel folding bike), and its rear frame, fenders and chainguard look to be identical to this Miyata / Sears. But the drivetrain is different, and from what I can tell this one does not tilt.

Here are two photos, one from eBay, and the other from random surfing (they look like twins, don't they? Maybe it's even the exact same trike in two different places.)



Now, recall the basket on the blue Miyata. It looks identical to the one on the above trikes! And so the plot thickens and I'm still going to presume that Miyata made my trike. Of course maybe Bridgestone made this trike for Miyata (not uncommon in the bike biz), but that does not explain the differences in the frame and drivetrain.

Mike Plummer and Kundstadt Sports recently confirmed for me that this was inded built by Miyata in the mid to late 1970's, as they sold a few of them back then. Since there's no info on the Net about a Miyata trike I'll perhaps become the main web resource for this little thing, just as my website seems to have the only info on the Auto-Mini folding bike (Google it and you'll see!). :)

I'd like to keep this trike for oddity's sake if nothing else, but it's way too small to ride comfortably. Its design really doesn't make much sense to me, but someone (or a design committee) put a lot of thought into it, and it got corporate approval to be manufactured. The tilting feature is cool, so it doesn't act like a regular trike and one can go around corners with ease, but then you also lose the stability while stopped that a conventional trike offers (because of course the frame will flop to either side if you're not paying attention). So all I can figure is that one gets the cornering of a 2-wheel bike, with the ability to carry a small load out back, and that's about it.

Oh, and just to make life interesting, Bridgestone makes a trike called the Minna, with two wheels in front!
