This is a 2016 Trek District IGH 3 700c commuter bike with a low-maintenance Gates Carbon Drive belt drive and a Shimano Nexus 3-speed internal gear hub. Includes Tektro mechanical disc brakes, a custom steel 57cm frame, and Bontrager components. Comfortable, reliable, and low maintenance. I bought this in 2016 and rode it for three years. It's been in a storage facility since.
