[True / False · Hard]

Answer: ✕ False

Explanation

The Rules of the Road, Chapter 3, Section 1, 2(1) states "the length must not exceed 190 centimeters and the width must not exceed 60 centimeters." The length standard is 190 centimeters, not 180 centimeters.

Hikari

So 180 cm long and 60 cm wide—that sounds about right for a small bike.

Momoka

Close, but that's false! The length limit is actually 190 centimeters, not 180. Width is correct at 60 cm, though!

Hikari

Ah, I was off by 10 cm! Easy mistake to make.

Momoka

Totally! Just think '190 and 60'—say it together and it'll stick!
