Bobbin Metric is a cool bike with lots of potential.

Don't laugh but as a space-efficient person...how about a multi-gear children's bike? It would be used as the beater bike. 20 inch multi-gear kid bikes are much easier to find than mini-velos. And plenty on CL too.

You may find the crank arms are wery short (low BB), and if you install longer ones they will hit the ground when cornering.
Not that I need another bike...

yes. i have to agree. also, i think the best of them all was the sillgey piccolo. wow. such a nice full cromo bike with very nice details. the mk2 had scalloped seat tube, custom dropouts and seatstay pins. that this platform hasn't really succeeded in the US yet is down to marketing.

Thank you all for the replies, there are some nice looking rides. I like the looks of of Biria Mini 20 and also the Bobbin Metric, the Bobbin looks to be from the UK, are there any dealers in Canada or US that have these?

That is a beautiful bike, but why did they put the rear brake where they did? Under the seatstays would have avoided that extra loop on the brake housing and would have made the rear brake housing (+ brake wire) much shorter..
Possibly you get less flex in the brakes by putting it before the supporting stays than after but then another option is on the chain stays like the NWT. Looks like a city bike so that would have been fine.

I tarted up my Nano to make it a decent fun bike, and with some different equipment priorities, it could be a very decent commuter as well. It's fitted with fender and rack mounts, and cheap enough it can be customized for duty for not a lot of money.
As noted upthread, it's pretty crappy out of the box, but it has the basic elements of a decent bike, you just have to double the spend on it and do it yourself!
For me, I just wanted something unusual and fun, and that's what I got!

935 is also the wheelbase for the sillgey piccolo and i think, if i recall correctly, is also the respect mini 2.0 measurement as well. i think this is too short for an everyday commuting bike. fine for an urban trick/ skateboard park bike, and that's how the respect mini velo was marketed.

i think soma got it right with their mini. the 55cm size had a wheelbase of 1010mm. for reference, a brompton is 1050mm and that's a very important factor in smoothing out the ride and improving the handling on 16" wheels, in that case.

I find that the sizing isn't the issue. The issue is the stigma attached to an adult riding a bike with 20" or smaller wheels. I've gotten many positive comments, but I'd also gotten the crass individual who tells me to get an adult sized bike,... before I breezed past them on their supposed adult size ride.
It's all about acceptance, and people in the USA think smaller wheeled bikes are for children only.

When I saw adults in London riding around on 16 inch Bromptons for the first time it looked comical to me. 20 inch wheels are the pretty much the standard for folders and mini velos. I think 20 inch wheels are fine though, anything lower and you're getting into micro territory. A pothole could swallow a 16 incher. The diamond frame of the mini velo makes it look more like a regular bike.

I have been commuting on a Bike Friday diamond-frame New World Tourist: 20" wheels, derailleur replaced with an Alfine 11. I added bar-ends and a high-pressure rear tyre. (I rather like the whirr of the low-pressure front tyre, and it absorbs bumps well.)
Fast, stable, fun to ride. I have no hesitation in recommending commuting on 20" wheels.
If I didn't have the dNWT, I would buy a 20Something or this fine-looking Bobbin about which I learned here today. Confound this site for inspiring too many bicycle purchases. (o;

Here's a picture of the dNWT. (Not my bicycle; picture from the InterWebs.)

If I didn't need my bike to fold, I'd be looking towards a Vanmoof T series

I first saw it on the amusing Bike Instructor's Guide to Cycling in Amsterdam video

it's ok, you can round up to 935mm, no one will hold you to a machinist's standard of accuracy.
935 is also the wheelbase for the sillgey piccolo and i think, if i recall correctly, is also the respect mini 2.0 measurement as well. i think this is too short for an everyday commuting bike. fine for an urban trick/ skateboard park bike, and that's how the respect mini velo was marketed.

The Soma was a nice, handsome frame! I wasn't sure a minivelo was going to be of durable interest to me, so I went cheap with the Nano just to see, but had Soma fitted sidepulls rather than canti brakes, and I'd been able to catch one at $750, I'd almost certainly have done that rather than Nano, but I'm not unhappy with the situation.

Those are very cool bikes. Maybe a litle upscale for a commuter, maybe not. If not, how about Ti?
