2023 All-City Big Block (Night Sky / Smoke) 49cm

Built for city shenanigans and curious escapades, Big Block is a fixed-gear steel machine powering low-maintenance lifestyles that want fast with their fun. A responsive yet comfortable frameset and generous tire clearance allows for top-tier handling as you soak up road chatter and good vibes with the gang.

Stock bikes are set up fixed gear with front & rear hand brakes. Ask us about customization including handlebar options or a Singlespeed Freewheel to allow coasting on hills.
