I'll get right into it.

Can a frame number on a bicycle have the letter "G" in it?

Thanks.

I need to know this urgently!

If it is a Serial number, it can include both letters and numbers, and they usually do..

Precisely like license plates on cars.. they include both..

In my case, it's a Bicycle.

This is the bike: Boardman Mountain Bike Pro 29er

SO?

He answered your question .

I have one with an "A" in it. Most Russian bikes will not have a "G", though.
