Autobike
Posted by Packard Newbie On 2020/4/28 19:50:02
Hey Guys,
I know this is thoroughly off Packard topic, but didn't want to step on Ernie's 'Packard Trips' post, (which I love, Ernie) and we had got to talking about bikes and such, and I had mentioned my Autobike, which is kind of an odd bird. It shifts through a 6 gear derailleur automatically via a 'constant-drive' counterweight concept. I believe it is 30 RPM that is the designated 'ideal pedal speed' and one starts out in 1st gear; as soon as 31 RPM's are achieved, the unit shifts up a gear, and so on. The down shifting is governed by the wheel speed, so if in 2nd or 3rd gear say, one can free-wheel, or coast and the gear does not change, until the bike speed reduces to the equivalent of 29 RPM in a given gear. Neat concept and I have to say, it works very well. I've had the bike for about 30 years and it has not given me any problems. Few pics attached at Ross' request.
