I really only need one and that's my 2003 GT Karakoram with the Xtracycle long frame. SO here's my list of "must haves" if money was no option:
2. Terratrike Rover with the tandem addition and Nuvinci hub
3. 4 person pedal surrey
4. Monkey bike (already have but it's hard for me to ride)
5. **********
