I think Scout is perfect - as are many of the other names that show people's creativity.

I am very boring by comparison. I tried naming my bikes eg my flat bar Avanti Blade was Ava (not very original and even then it didn't stick and she is usually referred to as 'the Avanti). My Cannondale Synapse is 'the Synapse' and my Specialized Amira is 'the Amira'.

Azfiddle - I'm clearly not one to give advice on this topic but I like Sapphire for your bike. Perhaps because I have a blue burmese cat that I named Sapphire.
