Named eBike routes and access checks
1. Neal Smith Trail: Des Moines to Big Creek
The Neal Smith Trail is the longest corridor in this guide. It runs from Des Moines north to Big Creek State Park. A 13-mile section is a National Recreation Trail managed by the U.S. Army Corps of Engineers at Saylorville Lake, so the Corps, not the county, sets the rules there. The Oralabor Gateway Trail, 4.25 miles, links the Neal Smith to Ankeny. That makes it useful for riders who want to connect to other routes. Sources disagree on total length: TrailLink and the National Recreation Trail listing give about 24.5 to 26 miles. Treat any figure as approximate and plan your battery with room to spare. Because more than one agency is involved, check the Corps page for current guidance before you ride.
Distance: About 24.5 to 26 miles, per TrailLink and the National Recreation Trail listing, which differ; start: Des Moines and Big Creek State Park are the ends; check the manager map for access points; surface: Check the manager page for current surface.
eBike access: The Corps manages a 13-mile section, so check its page for eBike rules there. County paved-trail rules cap eBikes at 20 mph on county sections. Etiquette and planning: Carry enough battery for the full out-and-back, since the route is long. Keep right, pass with a call, and slow where the path is shared. Managing source: USACE Saylorville Lake, trails page.
2. Gay Lea Wilson Trail, paved county trail near Ankeny
The Gay Lea Wilson Trail is a paved Polk County trail in the Ankeny, Altoona and Pleasant Hill area. It has a west section of about 7.5 miles and a 5.9-mile east spur. That makes it a manageable ride for a shorter outing, or a link between neighboring towns. Polk County Conservation manages it, so the county park rules apply directly. eBikes that meet Iowa's definition are allowed on this paved trail at or below 20 mph. That includes Class 1, Class 2 and Class 3 bikes, though a Class 3 can assist up to 28 mph and must hold to the trail limit. Check the county page for closures and trailhead details before you set out.
Distance: About 7.5 miles west section plus a 5.9-mile east spur, per Polk County Conservation; start: Several access points; check the manager map; surface: Paved, per Polk County Conservation.
eBike access: Allowed under county rules for eBikes that meet Iowa's definition, at or below 20 mph, because the trail is paved. Etiquette and planning: Hold to 20 mph even on a Class 3 bike. Slow at road crossings and when passing walkers, and check the county page before you go. Managing source: Polk County Conservation, Gay Lea Wilson Trail.
3. High Trestle Trail: Ankeny toward Woodward
The High Trestle Trail runs 25 miles from Ankeny to Woodward. Polk County manages 9.6 miles of it. The famous half-mile, 13-story lighted trestle bridge is in Boone County near Madrid, so it lies beyond the county section. Riders who want the bridge should plan a one-way or out-and-back trip that goes well past the county line. That is a long day on a single battery, so check your range. On the county section, the county rule applies: eBikes that meet Iowa's definition may ride the paved trail at or below 20 mph. Rules in other counties may differ, so confirm them with the manager of each section before you leave.
Distance: 25 miles total, with 9.6 miles managed by Polk County, per Polk County Conservation; start: Ankeny is the Polk County end; check the manager map for access points; surface: Check the manager page for current surface.
eBike access: County rules allow eBikes on paved recreation trails at or below 20 mph. Check other counties' managers for rules past the county line. Etiquette and planning: Plan battery range for a long ride and carry a charger plan. The trestle bridge is a popular stop, so slow down and share the space. Managing source: Polk County Conservation, High Trestle Trail.
4. Great Western Trail: Des Moines to Martensdale
The Great Western Trail runs 16.5 miles from Des Moines to Martensdale, according to the county parks portal. It heads south and out of the city, which makes it a good option when you want a different direction from the northern corridors. The county parks portal does not list its surface, and that matters for eBikes. County rules allow eBikes only on paved recreation trails, with Sycamore Trail and Fourmile Mountain Bike Park as the soft-surface exceptions. If the Great Western is not paved along your stretch, an eBike may not be allowed. Confirm the surface with the manager before you ride, and bring a charger plan for a one-way trip.
Distance: 16.5 miles, per the mycountyparks portal; start: Des Moines and Martensdale are the ends; check the manager map for access points; surface: Check the manager page for current surface.
eBike access: County rules allow eBikes on paved recreation trails at or below 20 mph, and not on soft-surface trails except two named exceptions. Etiquette and planning: Confirm the surface before you go. Plan a return or a ride home, since the route is one-way in length, and keep to 20 mph. Managing source: mycountyparks, Great Western Trail.
5. Sycamore Trail and Fourmile Mountain Bike Park, the soft-surface exceptions
Most soft-surface trails in Polk County parks are closed to eBikes. Two places are named as exceptions in the Polk County Conservation park rules: Sycamore Trail and Fourmile Mountain Bike Park. The park rules do not give lengths, trailheads or surface details for either, so this entry is a rules note rather than a route description. If you ride mountain bikes with a motor, these are the two places to ask about. Call or read the county page for current conditions and any closures. Elsewhere, assume that unpaved trails in county parks are off limits unless the county rules say otherwise.
Distance: The manager page does not list a length; check it directly; start: Several access points; check the manager map; surface: Soft surface, per the county rule that names these as exceptions.
eBike access: Named exceptions to the county ban on eBikes on soft-surface trails. The 20 mph limit and Iowa's eBike definition still apply. Etiquette and planning: Check conditions and closures before you go. Yield on narrow trails, and stay off any soft-surface trail not named in the county rules. Managing source: Polk County Conservation, park rules and FAQs.
Planning a Polk County ride
The manager pages do not list charging details for specific trailheads, so charge at home and plan for range. Long routes such as the Neal Smith Trail, at about 24.5 to 26 miles, and the High Trestle Trail, at 25 miles, can strain a battery on a round trip. Ask any shop you visit whether it will charge bikes. Check each manager page for closures before you go.
The manager pages list no ferries or transit options for Polk County trails, so this guide does not cover them. Des Moines BCycle has bike sharing stations, including one at 2nd Ave & Court Ave. The manager pages do not give trail crowd data either. Expect shared paths to be busier on pleasant weekends, and slow down when you pass.
Half-day and full-day eBike plans
Half day: Ride the Gay Lea Wilson Trail. Its west section is about 7.5 miles and its east spur is 5.9 miles, both paved. You could ride one section out and back and still have charge left. Check the county page for access points and closures first.
Full day: Take the Neal Smith Trail from Des Moines toward Big Creek State Park. It is about 24.5 to 26 miles one way, so plan a charge stop or a one-way plan. Check the Corps page for rules on its 13-mile section.
Rainy-season backup: Rent from a Des Moines BCycle station or Kyle's Bikes and ride a short paved section. Check the Polk County Conservation page for closures, and stay off soft-surface trails, which are closed to eBikes.
What not to ride in Polk County
Soft-surface county trails: Polk County Conservation does not allow eBikes on soft-surface trails. The two exceptions are Sycamore Trail and Fourmile Mountain Bike Park. If you cannot tell whether a trail is paved, treat it as closed until the county confirms.
Trails above 20 mph: County paved trails cap eBikes at 20 mph. A Class 3 bike can assist up to 28 mph, so you must hold back on these trails. Speeding is a poor idea on shared paths.
Unknown surfaces: The manager pages do not state the surface of the Great Western Trail, the High Trestle Trail or the Neal Smith Trail, so do not assume pavement. Check the manager page, and do not take an eBike onto a stretch you cannot confirm.
Corps-managed sections without checking: The Corps manages a 13-mile section of the Neal Smith Trail at Saylorville Lake. The USACE trails page is the place to find its eBike rule, so read it before you ride that stretch.
When to ride Polk County
The manager pages give no hours or seasonal closures, so check each manager page before you ride. Iowa summers can be hot and humid, and winters bring snow and ice that make paved trails unsafe. Spring and fall are usually comfortable for long rides, though conditions vary. Heat and cold both drain batteries faster, so plan extra range. Weekends on shared paths are likely busier, so early starts can help.
Iowa eBike laws and route permission
Iowa defines a low-speed electric bicycle in Iowa Code 321.1(36A) and sets the rules for riding one in section 321.235B. There are three classes. Class 1 has pedal assist only and stops assisting at 20 mph. Class 2 has a throttle and tops out at 20 mph. Class 3 has pedal assist and stops assisting at 28 mph. In every class the motor must be under 750 watts. A bike that does not fit these limits is not a low-speed electric bicycle under this law. Check the class label on your bike before you ride.
Under section 321.235B(9)(a), you may ride a low-speed electric bicycle anywhere a regular bicycle may go. That includes streets, shoulders, bike lanes, bikeways and multi-use paths. Sidewalk riding is set locally, so check city rules before riding on one. Riders under 16 may not operate a Class 3 eBike, but they may ride on one as a passenger. On a bike lane or multi-use path, a Class 3 rider may not go faster than the posted limit, or 20 mph if no limit is posted. The rules came from 2021 Acts ch. 125 (HF 493).
Iowa has no statewide helmet law, so helmets are not required by the state for eBike riders of any age. Low-speed electric bicycles also need no license, registration or insurance, according to 2021 Iowa Acts ch. 125. A helmet is still a smart choice, especially on a faster Class 3. Local rules may differ from the state baseline, so check with your city or county. For a fuller walkthrough, read our guide to Iowa eBike laws.
The state rule says an eBike may go where a bicycle may go, including multi-use paths. Trail managers such as county conservation boards can post their own rules, including limits on soft-surface trails, so check signs at each trailhead. Before you plan a ride, check with the park or trail manager. Do not assume that a state-level allowance settles access on every path. Ask about your eBike's class when you check.
Your bike's label matters on the trail. Bikes made on or after Jan 1, 2022 must carry a manufacturer label showing class, top assisted speed and wattage. Iowa law bars knowingly changing a bike's speed or engagement outside its class without a new label. On a bike lane or multi-use path, Class 3 riders must stay at or under the posted limit, or 20 mph if none is posted. Class 3 riders under 16 may not operate the bike. Keep your label readable and your speedometer working.
Polk County Conservation sets the rules on county trails. eBikes are allowed on paved recreation trails if they meet Iowa's definition and stay at or below 20 mph. They are not allowed on soft-surface trails, except Sycamore Trail and Fourmile Mountain Bike Park. The source is the county park rules page.
Other managers set their own rules. The U.S. Army Corps of Engineers manages a 13-mile National Recreation Trail section of the Neal Smith Trail at Saylorville Lake. The USACE page should be checked for its eBike rule, because none is listed here. City rules for Des Moines, Ankeny and others are not listed either.
One source conflict: the Neal Smith Trail is listed at about 24.5 to 26 miles, depending on TrailLink and the National Recreation Trail listing, which differ. The manager pages show no pending rule changes as of October 9, 2026. The state rules are in our Iowa eBike laws guide.
