Advent Speeder Bikes: 2023 vs 2018 vs 2014. Speeder Bikes have also appeared numerous times over the years. The 2014 version is done up as Santa’a sleigh complete with toy sack. (Fun fact: the 2018 speeder was photographed in the Amazon rain forest!) There was another bike in the 2021 calendar, but that year I must have been overwhelmed by life and never photographed anything past day 5.
