# Riddle I have no idea: “One for the front / Two for the back …”

One for the front
Two for the back
You will never need three.
What is this?

I thought it might be personality.

• Just to clarify, I thought it might be personality. is not part of the riddle right? :P – DrunkWolf Oct 22 '15 at 13:46
• To add more to DrunkWolf's question, does this mean you don't know the answer? – Aggie Kidd Oct 22 '15 at 13:51
• Rolled back because I'm unsure whether the edit removes important information, and would rather leave it to OP to decide. – user20 Oct 22 '15 at 19:38

Mirror

(one to see your front; two to see your back; you never need three)

It's the letter 'o'.
At the front of 'one', at the back of 'two' and none in 'three'.

• Clever, but I think it would be "you'll never need it for three" - the way it's written now, it makes no sense. – Deusovi Oct 23 '15 at 13:14

This is

a tricycle. 1 wheel in front, two in back. You would never need three wheels in either position.

• What do they call those things that have 2 wheels in the front and 1 in the back? – John Odom Oct 22 '15 at 19:43
• @JohnOdom en.wikipedia.org/wiki/Tricycle according to wikipedia it's called a tadpole tricycle. The more common example I references being called a delta tricycle. – Alexis Andersen Oct 22 '15 at 19:52
