Can We Make Bicycles Sustainable Again?

First, solve bike theft.<p>(Then, don&#x27;t demonize the e-bike. It allows longer journeys by bike, makes a bike a realistic option for older and less healthy people who couldn&#x27;t get around by pedal power alone, and makes it a more fun&#x2F;appealing option for healthy people)

Amen to that! An old steel bike like that, aside from lasting almost indefinitely if you don&#x27;t let it rust to pieces, is a platform.<p>I could take the bike shown at the top of the article and upgrade it to a modern 2x11 road geartrain, with external bottom bracket bearings, hollow shaft bottom bracket, brifters, the whole works. Longer axles on modern rear wheels? No problem to bend the frame slightly - it&#x27;s steel! - to make them fit perfectly. I&#x27;ve done it. I have a 40 year old steelie that is currently at 2x8 and could go to 2x10 without changing the rear hub again. It rides at least as nice as a modern carbon fiber marvel. It is of course heavier (12kg all up).<p>Another of my road bikes has the drive train from a similar vintage mountain bike. I wanted a triple, and the simplest way was to just transplant the long cage derailer to go with it.<p>Modern bikes that I see in the bike racks at work? Carbon fiber marvels with integrated e-bike drivetrain. They&#x27;re only a motor failure, or even a worn out battery pack (assuming not available any more from the manufacturer as spares) away from being e-waste just like all other modern gadgets. Retrofit to different brand stuff? Forget it. The frame is an integrated design with the drivetrain.<p>But how do you roll back time and get people to ride &quot;sensible&quot; bikes again? When the modern marvels can be manufactured just as cheaply and they&#x27;re just so much cooler? Good luck with that.

The author points out that China produces 55,000 bikes a day in factories using robotics with a certain energy and CO2 impact -- but should compare that impact to that of laborers producing the same amount of bicycles the old-fashioned way, including the impact of transporting them to and from the place of work.

Very frustrating to have an otherwise well maintained mountain bike and bombproof wheelset with a snapped fork. To get a new fork I need a new frame and front wheel. 20mm-thru axles are no longer popular. Headsets similarly have changed design.<p>At this point I have a room of partial bicycles just collecting dust.<p>When new some of these bicycles were more valuable (retail price of all components) than a cheap used car. Then there&#x27;s the problem of importing them, dealing with customs shakedowns or traveling abroad to purchase them.<p>Internal gearhubs and fat chains are a good choice if you are looking for longevity. Avoid the latest fads where possible. For my usage weight savings is secondary to overall durability.<p><a href="https:&#x2F;&#x2F;www.sheldonbrown.com&#x2F;internal-gears.html" rel="nofollow">https:&#x2F;&#x2F;www.sheldonbrown.com&#x2F;internal-gears.html</a>

Bicycle shaped objects[1] should just be banned.<p>They&#x27;re a major contributor to the reason that people think that cycling is some sort of sweaty uncomfortable grimness, because they&#x27;re sold some sort of double-suspension chinesium thing that barely even moves before it breaks a few months later.<p>Literally everyone who rides these, you introduce them to a 300 quid hybrid or road bike and they&#x27;re dumbfounded by how smooth the experience is.<p>[1]<a href="https:&#x2F;&#x2F;www.thecyclingexperts.co.uk&#x2F;get-cycling&#x2F;buying-a-bike&#x2F;the-bicycle-shaped-object&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.thecyclingexperts.co.uk&#x2F;get-cycling&#x2F;buying-a-bik...</a>

I am all for reparability, but personally I don&#x27;t want to go back to some of the ways things were done 30-40 years ago and bikes are still great for the environment compared to the alternatives. My old car which I purchased used and had for 17 years is equal in weight to about 150 bicycles!<p>It&#x27;s true that modern cycling uses more disposable assemblies than in the past, but I&#x27;ve never had any problems finding parts to repair old bikes. I recently restored a 90&#x27;s flat-bar mountain bike for a friend of mine. It had an integrated brake&#x2F;shifter lever that I replaced with generic 3x7 shifters. Most flat-bar bikes with Shimano-compatible drive trains use Shimano index shifting (SIS) for both the front and rear derailleurs. The drive trains on bikes with higher-end drive trains are serviceable. Even when a part is not designed to be serviceable, there are often ways to service it. RJ the Bike Guy on YouTube does this a lot.<p>All that said, the market is headed towards single-derailleur drive trains with a large cassette on the back. It&#x27;s a change in technology. It simplifies the operation and maintenance of the bike. I prefer it. So, I may upgrade by road bike with a 3x7 drivetrain to a 1x12 drivetrain at some point in the future. I am sure tech will continue to improve so there will probably other upgrades I&#x27;ll want to make in the future too.<p>The amount of waste generated by these upgrades and part-swaps is inconsequential in the grand scheme of things.

Shared bikes should be at the top because they will actually be ridden for that 15K or 50K miles, whereas a personal bike gets no where near that mileage.

I&#x27;m surprised there aren&#x27;t greater economies of scale for bicycles, especially bikeshare bikes. A rough approximation... Bikes are almost 3 times more expensive per pound than cars while being much simpler.<p>A citibike weighs 45 lbs, costs $1000 which equals $22&#x2F;lb<p>A Toyota Corolla weighs 2950 lbs, costs $20,000 which equals $7&#x2F;lb<p>I would think that we could have quality bikes for $500-$800, and high end bikes for $1000-$2000. Citibikes might be cheaper because they are contract manufactured for motivate, lower economies of scale, but probably cutting out a distributor&#x2F;bike shop middleman.

As people noted in previous thread about it being invalid on thru-axle measurements, it&#x27;s also invalid on cross-compatibility. All shimano road drivetrain components are cross compatible if they share the amount of gears <a href="https:&#x2F;&#x2F;productinfo.shimano.com&#x2F;#&#x2F;com?cid=C-453&amp;acid=C-455" rel="nofollow">https:&#x2F;&#x2F;productinfo.shimano.com&#x2F;#&#x2F;com?cid=C-453&amp;acid=C-455</a>. I can replace components on my 2015 11 speed shimano with ones from this year if they are also 11 speed.

I do think that old bikes are generally just better.<p>I&#x27;m finally on a modern road&#x2F;commuter bike, after two decades of only ever being on 19070s&#x2F;80s steel road bikes, and it&#x27;s just not as good. I paid more than three times as much for it, it&#x27;s heavier, and it&#x27;s harder to maintain, what with things like pneumatic disc brakes.<p>When this one finally goes, I&#x27;ll go back to craigslist like I always did and pick myself up an old road bike for $200.

Shimano Cues was recently announced and might help with some of the compatibility issues moving forward. <a href="https:&#x2F;&#x2F;bike.shimano.com&#x2F;en-US&#x2F;product&#x2F;component&#x2F;cues.html" rel="nofollow">https:&#x2F;&#x2F;bike.shimano.com&#x2F;en-US&#x2F;product&#x2F;component&#x2F;cues.html</a>
