http://www.flickr.com/photos/[email protected]/sets/72157621753599086/ These are some pictures of my 1975 Panasonic Tourist-10 road bike and 1970 era Raleigh Sports bike. The original speedometer that was on the Panasonic broke so I replaced it with the one shown. I found the speedometer on Ebay. The Trek light that is on the Panasonic bike I bought at my local bike shop. The Panasonic road bike is especially cool because the overrunning clutch is located in the front on the crank set. This design allows the chain and crank set sprockets to be in constant motion with the cassette and wheel set, while the cranks are stationary. The design was made for 3 years but then ditched due to it's low amount of strength. The Raleigh bike uses an internal 3 speed hub. Basically it's a planetary gear set and single cog instead of a cassette and derailleur.
