Draw a simple bicycle like the picture. It has two black wheels, a blue frame, a black seat, and a black handlebar. Use a black pen that is 3 pixels wide. The background stays white.
Draw the wheels first. Each wheel is an unfilled circle with radius 40. The circle’s center is at (-80, 0) for the rear wheel and (80, 0) for the front wheel.
Draw the frame with a blue pen. Use these connected lines:
| Part | Points in order |
|---|---|
| Lower frame triangle | (-80, 0), (-10, 0), (-30, 60), (-80, 0) |
| Upper and diagonal frame | (-30, 60), (60, 60), (-10, 0) |
| Front fork | (60, 60), (80, 0) |
Draw the black seat and handlebar:
| Part | Points in order |
|---|---|
| Seat post and seat | (-30, 60), (-30, 72); then (-45, 72) to (-15, 72) |
| Handlebar | (60, 60), (55, 82), (72, 82) |
Use penup() and pendown() when you move between separate parts. Change the pen color before drawing the blue frame and the black parts.
