You push on the pedals to make your bike move. Wouldn’t it be nice if, while you were pushing with one leg, you could be lifting with the other? Twice as far for half the work? Sign me in!
Uh oh, the tire on the Orange Monster is flat!
How did it happen? What did you run over? What did you hit?
That’s a nifty bike you got there – too bad it’s not comfortable to ride. If only you could make it just a little bit bigger. You can! And it’s easy!
That bike is a great way to get around – and you can carry stuff in your backpack. But what if you don’t want to use a backpack, or you need to carry something a little heavier?
If you dread hills when you’re riding your bike, or if you’ve simply never quite figured out how the shifters work, this is great information to have.
You’ve been out riding all day, or you just want to take the thing out, but the tires seem gushy and squishy. Rats. Need to add some air.
