Having a bike registry does no good unless people know about it and use it.
Notably police, and bike resellers, and buyers.
You'll need to spread awareness of your service.
There is also the question of motivation for people to use it.
The person who stole a bike and is looking to sell it obviously won't be looking up the registry, he may even peel off the decal. The burden of looking up the bike will have to be on the potential buyer. But is this person really motivated to do so? He's about to get a nice bike at cutthroat price, does he really care to look up registration and suddenly find that it was stolen? Feeling guilt aside, there's no real consequence to the buyer for accepting the stolen bike if law enforcement does not recognize the authority of your registry.
I'd say that as nice as your website is, the point is moot unless those issues can be addressed first.
P.S. sucks that you lost a bike. I personally do not expect any form of registration to work for me and instead rely on my locking strategy. Consider carrying 2 independant locks, a U-Lock and a CableLock and using them both. U-Lock controls the frame and rear wheel, cable controls the front wheel, frame, and rear wheel.
