Remember the fun you had with your Erector Set when you were a kid? Well, now a company called Infento is making an Erector Set on steroids that can be used to build tricycles, wagons, or even full-on recumbent bikes.
There are 18 different models available, each of which requires just a hex key for assembly. All the frames are built from aluminum, while the sets aimed at teens include belt drives and disc brakes. Bonus points: several of the builds allow you to swap wheels for skis come winter.
If you're feeling truly adventurous, you can use the parts to build a unique, custom creation.
