Riley-Lowe started his career with League Two side Exeter City, where he came through the club’s academy before signing his first professional contract with the Grecians in 2014. He ended up making 14 first-team appearances for the club, in between having two highly successful loan spells in Cornwall with Truro. Following his release from the Devon side, he was quickly snapped up by the White Tigers on a permanent basis in the summer of 2017 where he starred across two campaigns and was named Player of the Year on both occasions before deciding to leave to join Bath City in 2019. He returned to City after a year away following his release from the Somerset side in 2020. He was named Truro Player of the Year in both 2021/2022 and 2022/2023. He captained the side to play off glory last season, playing every minute of every game.
