[Fleet 500]

I found the figures for my other bike.

This one is (I still have it) a "dirt bike" from about 1974. A Schwinn frame and I put it together using other components (rims, seat, tires, handlebars). See photo.

A single-speed bicycle with a coaster brake. Front tire 20"x1.75" and rear tire 20"x2.25".

Here are the figures I got back in the mid-to-late '70s:

0-10 mph-------------- 3.2 seconds
0-15 mph-------------- 4.2
0-20 mph-------------- 6.5
0-25 mph-------------- 10.0

Passing: 5-15 mph------ 4.3 secs.
--------10-20 mph------ 5.2

Top speed-------------- 27-28 mph on level ground

No 1/4 mile time, but I did do a 400 foot run... 14.2 seconds.

The 10-speed bike, of course, was faster off the line. The single-speed bike took a few seconds to gather some speed, but did well in the mid-range (10-20 mph).
