MILWAUKEE — Milwaukee County is moving toward a 15 mph speed limit on busy portions of the Oak Leaf Trail, as officials respond to safety concerns involving e-bikes, scooters and other fast-moving devices. The County Board’s Parks, Recreation and Culture Committee voted unanimously Tuesday, Sept. 29, to advance the proposal. It now goes to the full board for consideration; no final countywide rule has been approved. The limit would not mean uniform enforcement across the trail system. Milwaukee County Parks officials say they would focus on crowded areas where trail users cross paths, including the South Shore Beer Garden and the Brady Street bridge over Lincoln Memorial Drive. The proposal would also allow Parks to set lower limits where additional safety concerns arise. James Tarantino, deputy director of Milwaukee County Parks, said some trail sections are only 8 to 10 feet wide and were designed for walkers and conventional bicycles. The growing range of speeds among users, he said, can create hazards in those constrained spaces. Parks officials have said electric devices also make trails more accessible and expand transportation options, while emphasizing the need for people traveling at different speeds to share the paths safely. For now, the department is prioritizing education over new fines. County officials separately raised concerns about e-motos — electric vehicles resembling e-bikes or dirt bikes that do not fit Wisconsin’s three regulated e-bike classifications. Parks considers them motor vehicles, which are already barred from trail pathways where motor vehicles are prohibited. Officials said riders may not know their devices fall outside the state’s e-bike categories. The committee also approved a request for Parks and the county’s Office of Corporation Counsel to examine whether the County Board can set specific penalties for misuse of high-speed e-motos, and whether parents could be held responsible for violations by minor children. Officials are expected to report back in December.
