1898 Knoll’s Spring Frame Bicycle
with Pierce spring fork
28″ Wooden wheels with chain tread tubeless tyres
Perhaps the strangest thing about this rare bicycle is that despite its name, it is not actually a spring frame! The frame is rigid, there’s no pivot, and it doesn’t flex when ridden. Perhaps that’s why a Pierce spring fork has been added? Nevertheless it is one of the most curious bicycles ever made, and is one of only three surviving examples. US Collector Brant Mackley owns one, and he kindly sent me the documentation printed here.
I bought it in Europe and it’s now owned by an old friend in the US.
