No. Scooters are not allowed to ride on sidewalks or on the Riverwalk. Scooters are allowed to ride on streets, bike lanes, and trails.
Scooters may be parked in the street's parking lane or on the sidewalk. At least 4 feet of space must remain clear to allow for an accessible path for pedestrians. Scooters should be parked upright and should not block driveways, entryways, curb ramps, transit stops, parklets, loading zones, accessible parking spaces, or parking meters.
Scooter corrals are areas marked specifically for scooter parking by paint and posts, typically found close to intersections in the street's parking lane. Scooter corrals are intended to provide convenient, visible places to park scooters. Riders are encouraged but not required to park scooters in corrals.
Milwaukee has no age requirements to ride scooters. Operators are allowed to set their own minimum age requirements. Lime and Spin both require riders be at least 18 years of age.
