Three-wheeled bike / Tricycle in Japan

Hi!

I would just like to ask where I can buy a Three-wheeled bike / Tricycle in Tokyo ?

And what are the usual prices for this kind of bike? Just one speed and nothing fancy.

They look like this:

Thanks!

If nothing fancy, they should be in the range of 35,000 - 60,000 yen or so.

You can ask at your nearest bicycle shop.

Thanks so much for the reply! :D

Wow, they're quite expensive, aren't they?
I better check out the recycle shops first, hopefully they have this kind of bike.

Thanks again!
