Did you know that there are about two billion bikes whizzing around in the world? A predecessor of this popular vehicle was invented in the early 19th century by a German Baron, Karl von Drais, who joined two wagon wheels with a wooden frame and put a saddle on top. Kirkpatrick MacMillan, a Scottish blacksmith, added pedals to this vehicle in 1839. However, MacMillan’s velocipede put him behind bars, as he collided with a young girl when showcasing the vehicle. There’s no risk of collision when pedalling on the invention factory’s cyclodrome, as the wheels are tiny and move along a purpose-built racing track. You and your friends can sit on life-size bikes and pedal your way towards victory!
