By the 1870s we'd pretty much standardised on the "Safety Bicycle", which had a couple of smallish wheels about two and a half feet in olden days measurements in diameter, with a chain drive from a set of pedals mounted low in the frame to the rear wheel.
By the end of the 1880s, you had companies mass-producing bikes that wouldn't look unreasonable today. All we've done since is make them out of lighter metal, improve the brakes from pull rods to cables to hydraulic discs brakes, and give them more gears (it wouldn't be until the early 1900s that the first hub gears became available, with - perhaps surprisingly - derailleurs only coming along 100 years ago).

Yes, something like 200 years ago.
