Bikes benefit a lot from pneumatic tyres, pressure pumps, smooth asphalt (not cobbles), precision engineering of chains, chemistry of oils and lubricants, rust-proof steel, rubber brake pads with compounds that last long enough and resist rain, spring steel for suspension, cables that don't stretch. Without those things you get a wooden boneshaker hobby-horse, large, heavy, energy inefficient, incovenient: https://duckduckgo.com/?q=hobby+horse+victorian+bike&t=ffab&iar=images&iax=images&ia=images https://duckduckgo.com/?q=hobby+horse+victorian+bike&t=ffab&...
(And internal combustion engines; how are you going to distribute them around the Roman Empire by the tens of millions without trucks or ships?)
- Alex3917 4y agoThe key invention that made them possible was ball bearings. This is why the modern bicycle and the modern car were invented within a year or two of each other.
- alt227 4y ago...and roads, which were created for use by horses and carraiges.
- B1FF_PSUVM 4y agoYep, 90% materials, and so are other things like windsurfing, paragliding, etc. Very little of the "modern stuff the ancients didn't figure out" could be done without modern materials. If dumped back in time, maybe you could make rent teaching swimming or doing accounting. Medicine would probably be too dangerous.
- blululu 4y agoYeah. Surfing is a great example of a Stone Age sport that has been radically changed by Space Age technology. Koa wood gets you a longboard that is hard to steer and can only surf long smooth waves. The modern surfboard is very much born out of California's aviation industry and its fixation on light, strong materials and aerodynamics. Surfing Pipeline is only possible with modern plastics, fins and shaping.
- Khoth 4y agoTo expand on one of those things - bike chains get slightly longer as they wear out. Once it's about 1% longer than it started, it looks about the same as it always did, but it's starting to damage the drivechain and you need to replace it. An ancient Roman blacksmith has no hope of making a chain with anything like that level of precision.
- convolvatron 4y agoyou would have used leather belts. it would have been a pita, they stretch pretty fast...but its feasible I think.
- loeg 4y agoYeah. The vast majority of parts on a bicycle are the individual links in a chain. Manufacturing these to sufficient tolerance is quite challenging. Romans might have been able to do shaft-drive. Or Penny-farthings (direct pedal-wheel drive).
- thinkling 4y agoI believe you only have this problem if your bike has gears based on a set of sprockets (different size chainwheels and a derailleur to move the chain from one to the other). In Europe (Holland in particular), people ride single gear city bikes (or internally geared hubs) for decades without replacing chains or cogs. When you only have one chainring and one cog, they wear along with the chain, and it takes a very very long time to encounter problems. It's when you have the sprocket cluster with multiple cogs that are not all wearing equally, that you get problems. Or often the problem on geared bikes doesn't appear until you replace your worn chain and the new chain no longer meshes well with the cogs worn to match the old chain.

- sharkweek 4y agoAnd now of course some of the most prestigious races in the professional cycling world are across predominantly cobbled roads as a form of torture for those racing. https://cdn.mos.cms.futurecdn.net/hD4Vtdmow7B4Jf4XiWPH5g.jpg https://cdn.mos.cms.futurecdn.net/hD4Vtdmow7B4Jf4XiWPH5g.jpg

- temporarara 4y agoWell, I've got a bike from the 30s and it's perfectly fine for everyday riding. While I agree that most of those things you listed are valuable and convenient, good enough is often just good enough. Like I've got no use for any cables and I don't need precision engineered chains.
