Light Bulb is commonly credited as the invention of Thomas Edison. But the work on the light bulb was started 35 years before him though the product design of Thoman Edison was what was practically useful. In 1802 Humphry Davy, was the first to detect light in carbon by using electricity which came to be known as Electic Arc Lamp. This was followed by several other variations but none of them were suitable for commercial usage. Till platinum filament was introduced in the bulb by British scientist Warren de la Rue.
Then in 1850, this concept was further improvised by Joseph Wilson Swan by enclosing carbonized paper filaments in an evacuated glass bulb. But this design had a very short life span. In July 1874, Henry Woodward and his team got a patent for a new design but since they failed to commercialize their invention, it was sold to Thomas Edison. Finally, in 1878, Edison started his research on Light Bulbs using that patent as base and was able to successfully file a new design patent for light bulb on 4 Nov 1879, and began the era of light bulb's commercialization.

Bicycle was invented in 1817 by Karl Von Drais and it was meant to be pushed with your own feet as it had no pedals. The next iteration of the cycle had pedals added to it but it had no brakes. Then we saw Penny-Farthing cycles which started to become quite popular between 1870s to 1880s. Finally, in 1885 and Englishman introduced the first safety cycle which took bicycle's interest all over the world to another level altogether. 1894, Betty Bloomer's cycles, was the first woman-first designed bicycle followed by in 1920 when the first kids focussed bicycle was introduced which ended up evolving into geared bicycles and mountain bikes too.
