Back in the '70s, I did some acceleration times with my '74 Huffy 10-speed bicycle because I was curious.

Me on the bike and a brother doing the timing using a watch.

Here were the results:

0-10 mph--------- 1.4 seconds
0-15 mph--------- 3.2
0-20 mph--------- 5.0
0-30 mph--------- 18.0
0-35 mph--------- 33.0

Passing: 5-15 mph- 4.0

Actual 1/4 mile---- 33 seconds @ 35 mph
Top speed-------- Approx. 37 mph

I don't think I could match those times now, being about 30 lbs heavier and 30+ years older.


I also did a similar test with my early-'70s dirt bike, but I can't find those figures. They are around somewhere.
