Treehugger, which claims to have 4 million page views per month, tried to educate it's readers on the subtleties of the small wheel bicycle today.
Many think that any small wheeled bike is a folder, but it ain’t necessarily so. But it is true that small wheels do help a bicycle collapse into a neater package. That’s not to say these are toy bikes. Some ride theirs everyday to work (for years), others tour whole continents, while yet others have set world records for upright bicycles.
And in the list of featured "folders":
What: Pashley-Moulton TSR8
Where: Pashley; in the US, try Angle Lake Cyclery or North Road Bicycles
Why: From the original designer of front and rear suspension small wheel bikes, this eight speed hub geared, British-made spaceframe swiftly separates into two halves.
How much: $2,595
Nice touch: Front and rear carriers carry low, and have very stable centre of gravity.
