Dear Han:

Congradulations! That is wonderful news. I don't know the website but a popular crafts store that usually carries everything is Michaels. At least here in the states its very popular. You have gotten a lot of wonderful ideas including one I was going to suggest. As far as wedding toppers goes, its really easy to get a base and customize your own. I did that for our wedding eight years ago and my husband was so impressed. A lot of people don't even use typical wedding toppers so you could go that route and just look for a small figurine of two people riding a bike and use that as a cake topper. Stores that carry collectibles or decorative figurines would probably be the best place to find one. Depending on what kind of material a figurine like that is made of, it might even be possible to repaint the two figures to resemble you and your fiance. I painted the wedding couple on the cake topper I made to resemble my husband and I. I felt it was really important since all the usual wedding cake toppers have a blond bride and I have very dark hair. If I find out any good websites for crafts I'll email them to you.
