I bought two Autobikes, his and hers, about 10 years ago new from Seattle Traders, the outfit that bought the leftover inventory from the original sellers.
Paid about $160 total. The only bikes we owned until I bought another for spare parts only to discover that the derailleur was slightly different. the hills have gotten steeper this year and We need more gears. The three Auto bikes are free to a good home, but you must take all three, I need the room for our upgrades.
