Those suddenly ubiquitous, sky-blue bikes on Atlanta’s streets are marching northward.

Livable Buckhead officials send word that a Wednesday ribbon-cutting will officially mark the launch of bike share in Buckhead, at a time when the booming submarket’s multi-use trail is expanding and talk of added greenspace is getting real.

The three Buckhead stations—including hubs at Tower Place and Piedmont Center (3535 Piedmont Road NE)—will be an extension of Atlanta’s rapidly expanding Relay Bike Share.

The official kick-off happens at 12:30 p.m. Wednesday at Tower Place Park (coinciding with a weekly food truck event) and will include Bike Share 101 lessons and test rides to PATH400.

Added bonus: New bike share users at the event can snag a promo code for a $5 Relay Bike Share account credit.

The Relay program has come far in a year.

It launched in June 2016 with just 100 bikes at 10 stations around downtown; by April, officials were celebrating the arrival of 400 more “Big Blue” eight-speeds, which have been positioned at 60 stations around the city, from West End and Vine City to Old Fourth Ward’s Studioplex and Midtown’s Colony Square.
