Gearing a Hitchhiker/Trail-a-bike
I just bought a used Hitchhiker, a Trail-a-bike wannabe. It's got a
one-piece crank with bearings, but no chain or chainwheel, just a friction pad. 20" front wheel in back. I think the short cranks are a good size for my niece, but I'd like to gear it so she can pedal with me/us. (a lot of our riding is tandem) Assuming a sustained 15mph cruise, (subtracting about 3mph for the Hitchhiker) and a 20" wheel, what kind of gearing should I have? I'm probably going to go with a 5 speed freewheel, rather than trying to scrounge up a BMX freewheel, but I might not do shifters, depending. |

You want a gear of 26/20 x (whatever gear you are using on the 26" wheel towing bike), or use 27/20 x (whatever gear you are using on a 27" or 700c wheel towing bike). It would be simplest to put the same size freewheel on both the trailer and the tow-er, and use a chainring of a larger size on the trailer. Use the above formula. -- Ted Bennett Portland OR |
