Visit WTMJ.com for Summerfest transportation options, where they share the following about biking options to the Festival Grounds:

"If you want to avoid traffic completely, biking may be the easiest way to get close to the gates.

Henry Maier Festival Park sits near the Oak Leaf Trail and Hank Aaron State Trail. Summerfest says bike parking is available at the North Gate, Mid Gate and South Gate.

Bublr Bikes are also available near the grounds, including a station near Discovery World.

...

According to Eleni Jacobson with Bublr Bikes, there’s no problem handling the influx of riders near the fairgrounds. They’re staffing up Discovery World from one p-m to midnight daily, with dedicated crews constantly shuffling bikes back into the city so the supply doesn’t dry up."
