People said no-one would use the Smith Street bike track but council data claims thousands of riders are taking advantage of it.
The controversial pop-up bike path sparked opposition because it changed most of Smith Street into a one-way street.
Wollongong Lord Mayor Gordon Bradbery said council had been collecting data on the number of people using the path since it was completed a few months ago.
"What we've found is that the number of cyclists using the Smith Street pop-up cycleway has increased over the past couple of months with a total of 1983 trips recorded in June and 4333 trips recorded in August," Cr Bradbery said.
"It's wonderful to see so many people use the stay at home orders to re-evaluate how they travel when making shorter trips around their community."
Cr Bradbery said data will continue to be collected and reviewed in case the pop-up path needed some fine-tuning.
"What we hope to see in the long-term, as we move out of lockdown, is people continuing to include active transport options such as cycling in their usual mix of exercise and travel," he said.
"In the meantime, we'll continue to collect data along Smith Street and at other places along the pop-up cycleway routes to build a clearer picture of how people use these new facilities."
