If you're resolving to bike to work this year, you might want a bell like this one in our #ObjectProject. As cyclists took to urban streets beginning in the 1890s, adding to the crowd of streetcars, horse-drawn vehicles, and pedestrians, cities began regulating bicycles. Speed limits and use of bicycle bells helped cyclists navigate (and survive) "crush hour." ??? #HistoricalResolutions #RingInTheNewYear #BikingHistory #CyclingHistory
