In Sioux Falls, bike lane and trail rules are determined by the type of device you operate and the specific path you choose. The city’s 36-mile Recreation Trail system permits Class 1 and Class 2 e-bikes but enforces a mandatory 15 mph speed limit for all users. Conversely, Class 3 e-bikes, electric scooters, and electric one-wheels are prohibited on the shared-use trail system and are generally restricted to on-street bike lanes and roadways. Under South Dakota state law, bicycles are classified as vehicles when used on public highways, meaning riders must adhere to the same traffic signals and signs as motor vehicles.
The Sioux Falls Recreation Trail System
The Sioux Falls Recreation Trail is a dedicated 36-mile loop that circles the city. Because this is a shared-use path utilized by pedestrians, runners, and cyclists, the City of Sioux Falls Parks & Recreation department enforces specific safety mandates:
- Speed Limit: A strict 15 mph speed limit applies to all trail users.
- Passing: Riders should announce their presence (e.g., "passing on your left") before overtaking other users.
- Flow of Traffic: Always stay to the right except when passing.
- Stationary Rules: If you need to stop, you must move entirely off the paved surface to avoid obstructing the trail.
E-Bike and Micromobility Classifications
Access to the recreation trail depends on the classification of your e-bike or micromobility device. While Class 1 and Class 2 e-bikes are permitted on the trail system via city ordinance, higher-speed devices remain restricted to the streets.
| Device Type | Trail Access | Street/Bike Lane Access |
|---|---|---|
| Standard Bicycle | Allowed | Allowed |
| Class 1 E-Bike (Pedal-assist, max 20 mph) | Allowed | Allowed |
| Class 2 E-Bike (Throttle-assist, max 20 mph) | Allowed | Allowed |
| Class 3 E-Bike (Pedal-assist, max 28 mph) | Prohibited | Allowed |
| Electric Scooters | Prohibited | Allowed |
| Electric One-Wheels | Prohibited | Allowed |
Note: Restrictions on motorized devices do not apply to Other Power-Driven Mobility Devices (OPDMDs) used by individuals with disabilities, in accordance with ADA guidelines.
Roadway Rules and South Dakota State Law
When riding in on-street bike lanes or on the road, cyclists must follow South Dakota Codified Law, which treats bicycles as vehicles.
- Traffic Signals: Riders must stop at red lights and stop signs.
- Direction of Travel: You must ride in the same direction as motor vehicle traffic. Riding against traffic in a bike lane is illegal and increases the risk of collisions at intersections.
- Equipment: Riders should ensure their devices are equipped with front white lights and rear red reflectors or lights when riding between sunset and sunrise.
Trail Etiquette and Safety
To maintain safety on the shared-use system, the city requires specific trail etiquette. Groups are permitted to ride or walk no more than two-abreast. If the trail is crowded, users should move into a single-file formation to allow others to pass safely.
Because Class 3 e-bikes and scooters are prohibited on the trails, riders using these devices for commuting should plan routes that utilize the city's network of on-street bike lanes. Always verify your e-bike's classification by checking the manufacturer’s label, usually located on the frame or near the motor, before entering the recreation trail system.
Verification Checklist for Riders
- Identify your Class: Check the sticker on your e-bike frame to confirm if it is Class 1, 2, or 3.
- Monitor Speed: Use a bike computer or GPS app to ensure you stay under the 15 mph limit on the Recreation Trail.
- Check Lights: Ensure your front and rear lights are functional if riding near dawn or dusk.
- Yield: Always yield to pedestrians on shared-use paths and at crosswalks.
