here we go: I own a 1910 boyscout handbook:
Cycling

To obtain a merit badge for cycling a Scout must:
1. Ride a bicycle 50 miles in 10 hours
2. Repair a puncture
3. Take apart and clean a bicycle, and put it together again properly
4. Demonstrate how to make reports, if sent out scouting on a road.
5. read a map; and report correctly verbal messages.
