58 Tremendous Tricycles

Concept bikes aren't relegated to two-wheeled machines anymore. In fact, this list of tricycle concepts is proof there is a growing fascination with three-wheelers.

What used to be a toy bike for kids who weren't ready for a two-wheeled bike is now a legitimate object of innovation. Maybe adding one more wheel is just what bike designers need to add that extra element.

Here we see a luxurious looking royal tricycle made of metal, oak and cherry wood. It also includes 23k gold leaf, a Sony stereo, velvet accents and Swarovski crystals.

You can also pick up more than one kind of eco-tricycle concept bike. Since concept bikes in general are usually geared towards fuel efficiency, this development makes perfect sense.
