An old friend recently gave me a BikeE that had been sitting in storage
for the last 8 or so years. I'm interested in knowing what model it
is. It is blue, has a Sachs 3x7 hub, and does not have air suspension.

I'm also wondering what ISO size tires it uses, since a local
shop told me there are 2 sizes for the 16" and 20" wheels, and BikeE
used both of them over the course of the product line.

Thanks,
Ryan
