Considering all the riding I expect to do today, I doubt I'll see even one other MB. That's really sad considering Texas is so MB friendly.
In the last few years I have noticed a drastic increase in 2 wheel vehicles though. Especially low end chinese scooters between 50 and 150cc. Some of them are cheaper than a good MB. Honda Ruckus's have appeared out of nowhere, and none of them are stock. The Sport bike seen has exploded too, right along with big cruiser doosiers.
But motor bicycles? Nothin!!! Never used to see them, and still don't. Well, almost never. Except mine. Dallas needs a VMB bad. A low end shop might work, but Dallasites would probably be more attracted to high end stuff, at least at first. I think the uptown area would be a good point of attack. There's a lot of young people, and money, plus it's a good area for short distance travel. That's a important consideration in Dallas. A little success would breed competition from lower end shops.
The most important thing is, people need to see motor bicycles riding on the streets. Right now there's no awareness we even exist. Typical first builds won't get it done. We need high end builds to attract high end buyers. Dallasites are suckers for anything expensive that nobody else has. This could be anybody thinking about buying a new 50cc, $2500 Honda Ruckus, and then spend another $2500 customizing it.
I think one of the main motivations for getting a Ruckus is they're not scooters, or motorcycles, but they're cute, and different. MBs could fit in there somewhere, plus we have the advantage of no license, registration, or insurance, and we're a lot faster than a bicycle.
