I still think it's geared too high for even the small hills around here -- you just reminded me I snapped the chain last summer standing on the pedals on one of them.

Combination of raw strength and a 55 year old chain!

I will have to mention that to my nephew. He's more likely than me to use brute force than finesse.

If I had parts on hand, I would have changed the rear gear by now.

A 48/19 T combination is common and I have used a 40/19T with a 3 spd hub for stop and go city commuting.

End of season upgrade: generator powered headlight!

I just scored a fantastic bauble for the old girl:





Working condition! Milton 6 volt, 3 watt generator. Circa late 60's or early 70's.

It has spots for 3 bulbs, but only one works so far (fortunately that's the "high beam"). One is for a tail light, but the bulb & red lens are missing (broken).

The fun part is it uses the bike frame as the ground. Knurled knobs on the terminals secure the positive wire at the lights and generator.

I rode this bike more than usual this summer. Still don't like the gearing, but I'm not going to bother changing it - I resigned myself to standing up on the pedals on all hills & when starting out from a stop.
