Fly like the wind

I have been riding to work whenever I can. Sadly that turns out to be once a week, maximum, but there is time to work on that. I have been borrowing a bike that is great in every respect except that it is too big for me. I almost took a spectacular fall on a roundabout because my feet don't even nearly touch the ground when my bottom is on the seat. So, today we bought a bike that is especially for me! I think bikes on the whole are a bit of a man thing because the good ones don't come in a range of colours. Still, my bike is a delightful silver and now I just need a name.

As I rode it home from the bike shop I was thinking Flash. Too obvious? Then I thought it had to be Shadowfax. Too nerdy? There is also the fact that it will be ridden by me and will not, therefore, be flashing along or worthy of the name of Gandalf's horse. Any ideas?
