Green bike of the future

With this "green" movement in full swing now, what will the bike of the green future look like? . I would imagine there will be new products to replace the nasty oil related products in use now. I suppose the cable housings, tires, bar grips and wraps, plastic/carbon frames and paint will all be made of new products.
I'll be holding out for levitation regardless of the finished product. lol

Maybe get rid of carbon fiber parts and frames? They're not recyclable when no longer usable, and the fabrication process involves resins made from petrochemicals. Maybe use something recyclable, like . . . steel, or . . . aluminum?

Tires and tubes - rubber can be recycled, not sure if bicycle tires are included in the automotive-centered scrap tire recycling process.

Bicycles are already pretty efficient vehicles, so not sure there are any appreciable gains that can be made in the use of recyclable materials to either make new bicycles or in the scrap from worn-out bicycles. .

Whenever I see some smug looking Prius driver when I'm riding my 20? year old bike that's been faithfully helping me get around for years I look at them and notice they rarely look back. They know their carbon footprint is way higher than mine but don't want to admit it.

Listening to Bubba and Bubbette make fun of the Prius is depressing. You can imagine what comes out of their mouths . Bicycles will make the species extremely irate for no reason. Interesting phenomenon....

i don't think there will ever be any bicycle (or anything else) that's truly green. it may be the best we can do is drastically reduce our disproportionate production and rampant consumerist tendencies. besides, it's hard to improve on a second hand steel bike if speaking purely in terms of being "green"

The bike itself it pretty ‘green’ already. However the manufacturing process and lifecycle has a pretty linear model. To be more ‘green’ bicycle manufacturing itself needs to be greener.

Kale bike frames. Hey, it's been done with bamboo. When you're done riding it, toss it in the blender for a smoothie.

We need to rebuild cities to be energy efficient.

Part of that will be transportation, of course. Bikes will be a big part of that. Look at what the Netherlands has done. But there will be a lot of niches. Needs R&D, but small vehicles weighing at most a few hundred pounds, will play a role.

Aluminum almost certainly has a much higher carbon footprint compared to carbon fiber. Also, because of structural concerns, I would guess only virgin aluminum is used for frames or components. Titanium would be even worse. Steel would also have a high carbon footprint, but depends on how much recycled steel is used. Overall carbon fibers lifecycle carbon footprint is probably similar or lower than metal frames and parts.

OK so steel is out, aluminum is out, and CF is out... pretty much brings us to this:

Now if they can just do something about all those pesky wheels and components... SIGH.

I'd like to see a small electric vehicle that uses the same tech as the E-bikes we're seeing. These vehicles would bridge the gap between electric cars and electric bikes. Obviously, the tech would need to be beefier to haul more weight, operate in adverse conditions, etc. Maybe I'm dreaming, but it'd be nice to have an enclosed vehicle that I could run out for shopping and not have to pay the high dividends we're seeing for the electric vehicles coming out on the market.

At the moment, it's a cottage industry. What's needed is some R&D money to develop purpose built parts, like a scaled down version of what you see behind the front wheel of a front wheel drive car.

The technology already exists, and I'm pretty sure they'd sell like hotcakes in Europe, and for us once we start acting sane (you don't have to say it). There is a new generation of batteries coming, they'll be cheaper, and that will help with the cost, since 2 to 4KW of storage is quite expensive using lithium.

Leather seats and bigger tires for rougher roads, which will be more dirt and cobblestone and less asphalt. Maybe shaft drive. More utilitarian and practical designs, less sporty toys.

a few hundred pounds wouldn't be safe or durable in most cases of transportation. there's a lot to be said for the old vehicles made of steel and road like a boat. mainly, they're repairable and could last the lifetime of it's owner. new cars in part are repairable, but if wrecked, for example, they're hugely expensive to do so and in many cases simply have to be totaled. while they're better at fuel consumption, they still draw on a lot more resource and industry operation for production (mostly foreign in both cases) than the old cars. iow's, the materials needed to produce the old were far fewer and were sourced and assembled right at home with far less transport.....which is another huge...really huge....carbon factor. so, if you really start thinking about it, the carbon print with "greener" cars is a bit of a toss. and, i'm not trying to be a debbie downer, either. it's something i've given plenty of thought to.

it may have been in the 70's, but there was a fellow through methods and modification was able to derive near or over 100mpg's on a carbureted vehicle. it may have been less, but still....even if it was say only 70mpg's, that's still better than any hybrid/green car in existence or that could be produced with current "allowed" technology (ie...not suppressed).

In my opinion a true green bike of the future would need to replace a car for the majority of users for the majority of their needs.

To accomplish that it would need to do the following
  1. Cover a 20 mile commute in under an hour.
  2. Provide comfortable riding in all weather conditions
  3. Get the user to the destination with minimal sweating
  4. Carry groceries and other small items.
In my opinion the only way to do this is an electric assist velomobile. And it would still struggle with acceptance since many people would want the ability to carry a child or grandchild.

I believe they would sell very well in Europe and possibly Japan. I think that if these little vehicles are slow enough, light enough, and strong enough, the USA would need to relax their safety standards enough to allow them on the roads in quantity.

Jane Jacobs liked to say that roads are city killers. You'd need to read her work to fully understand.

If you limit larger vehicles to what is absolutely needed, safety isn't an issue. You can limit trucks to the night, limit where cars can go, basically shoving most of them out of the city, and limiting the rest to the outskirts.

Cities are for people.

Driving is only one part of the energy cost of suburban living. Others are electricity loss as waste heat over miles of steel wire, pumping water for many extra miles, maintaining many extra miles of roads, mowing lawns, heating big drafty houses, etc. Bikes won't save the burbs. Farmers may bike 20 miles, but urbanites are more likely to ride in the single digits.

There is nothing that can save the burbs, and you just laid out why. The costs exceed what the tax base can afford in most places.
