Yep, Bikes are popular. That's good.
Bikes were here before cars, and will be here after cars.
The bicycle is a perfect invention. It's like rock and roll. Once you hear it you feel like it's been here forever.
It'll never die (rock and roll), and neither will the bike. 500 years from now the bike will still be in use. Imagine getting to 20mph easily on a flat surface with little effort.
It needs no fuel, doesn't eat or poop, and has cheap parts that are easy to replace.
