No, it can't be a motorcycle if it has 4 wheels. By definition, a motorcycle has 2 wheels. I've been thinking, though. Of course, when I start thinking, I always discover a dozen or more questions. Maybe someone here on the Vine can either shed some light on my thoughts and help them develop into grand things, or help me see where it would be completely unfeasible to see this idea come to life.
There are motorcycles on the market today that get what, 60mpg? These engines can go 70 mph, and are available for $4000 or even less, new. Add 2 wheels to that machine, and what happens? I have sense enough to know that added weight would decrease mpg and mph. I also understand that the expense of axles and 2 more tires would increase the price a little. So, theoretically, this machine, or one similar, could provide at least 30 mpg and potentially go 40 mph (or more) for $6000....or so. No, it wouldn't have the power of a hemi, or even a 4-cylinder engine, but couldn't it be an affordable alternative for people who don't need to go 70mph? (That's too fast anyway, for my taste.)
Imagine a dunebuggy with blinkers....one that I can drive on a city street, running errands much more efficiently than ever before...one that can be used to taxi people to the market, or the doctor's office, or even to the community coffeeshop affordably.... Why not? It shouldn't be all that complicated or expensive to make the minor modifications that would make it street-legal.
Well, there's a safety issue. All-terrain vehicles are not meant for roadways because they fall short of highway safety standards. When I think about that, though, I remember: A. this vehicle shouldn't be intended for major highway use, B. motorcycles don't have rollbars and seatbelts, and C. most every mode of transportation is subject to significant damage upon impact.
Granted, it would be slower, but if we look around our country today, we have to agree that life is going to slow down whether we want it to or not. Fuel efficiency would be great. It could considerably lessen emissions that are slowly killing the air we like to breathe. It would be affordable, much more so than the little $15,000 'economy' cars that the auto industry has been saddling us with. The sales tax would be more affordable. The insurance would be more reasonable.
I think I like this idea. Now, how do I get someone to build me one?
