A handcycle is a special kind of bicycle that you ride using only your arms instead of your legs. It's a fun way to exercise and explore the outdoors for people who can't use their legs or have trouble walking.
To ride a handcycle, you sit in a special seat that is low to the ground and has a backrest. You reach forward with your arms and grab onto two handles that are attached to the pedals. You then use your arms to pedal the bike, just like you would use your legs on a regular bike.
Handcycles come in different shapes and sizes, depending on what kind of riding you want to do. Some handcycles are designed for racing, so they are very light and aerodynamic. Others are designed for cruising around town or on bike paths, so they are more comfortable and stable.
One cool thing about handcycles is that they can go really fast! Some people who ride handcycles have even raced in competitions against regular bikes and been able to keep up.
Overall, handcycles are a great way for people who can't use their legs to enjoy the freedom and fun of biking. And who knows, maybe one day you'll get to try one out for yourself!
