Either my googlefu has failed me, or I've just discovered a new niche! Little Model Bikes (TM)…

Does anyone know where I could get a model bike or (better) a model tandem?

A nice looking diecast one would be ideal – it's for our wedding cake.

Finger Bikes, but they're all BMXs.

Iv see the small metal ones around a fair bit usally about 4" tall but might be too bid/wrong look.

We were given this as a christmas present.

Think it'd be a bit heavy to go on a cake though. 😉

put, del prado metal model bicycle, on a ebay search £19.99 buy it now from france, the only one i've seen
EDIT or google del prado model bicycles, i think there's loads
you could have a chopper 😀

This is a titanium keyring. muji do a similar one

use a lego one

I have a chum who does fimo cake toppers. She has done a kayak for me with my folks in.

There are a couple here (USA though) – they have an ebay store too.

Google search for 'diecast tandem bicycle' bring up a few others.
