How we verified this: We focused on legal use—what helps riders follow posted rules. We reviewed each platform’s official documentation (offline maps, trail status/closures, and routing behavior), plus federal land-manager guidance (NPS/USFS/BLM). Verified as of . This page is informational and not legal advice; always follow on-site postings.

Most “best app” comparisons chase features and social clout. Our lens is narrower: which app helps you ride where you’re allowed to ride, avoid closed segments, and carry the right map when you lose signal.

Short version: Trailforks is strongest for finding MTB trails, conditions, and closures in many regions; MTB Project is a solid free option in many areas; Strava excels at recording, segments, and social but is not a trail-access authority. Use them together—the right stack helps you stay on legal routes and avoid closed segments.

Our Criteria: Legality & Compliance First

Trail Access Signals

  • Shows trail status/conditions and closure cues where networks publish them
  • Notes on bike/e-bike allowance where provided (still verify locally)
  • Clear trail directionality and difficulty notes

Offline Reliability

  • True offline downloads (not just “recently cached” tiles)
  • Readable trail labels and junction context
  • Battery-friendly navigation behavior

Local Rule Awareness

  • Encourages reliance on land-manager postings and designations
  • Handles seasonal closures and status updates where available
  • Avoids implying access where none exists

What Each App Does Best (for Riding Legally)

Trailforks

  • Strong for MTB trail discovery and trail-network management tools used by many trail groups and regions.
  • Offline maps and offline trail data support.
  • Conditions/status and reports are surfaced where networks and users contribute updates.

Use it when: You need a dedicated trail map with offline options and status/condition awareness.

MTB Project

  • Free, curated trail guides with descriptions and photos.
  • Offline support (downloaded trails work offline), but background map behavior can vary when you’re fully offline.
  • Good backup map in many classic U.S. MTB zones; community-driven.

Use it when: You want a no-cost backup map and a second opinion on routes.

Strava

  • Recording, training history, and route planning for mixed-surface rides.
  • Heatmaps show where people ride—but heat ≠ legal access.
  • Offline route maps exist for downloaded routes, but it still isn’t a land-manager legality source.

Use it when: You want tracking and routes, then confirm access/closures with a trail map + land-manager postings.

Critical: Following a Strava heatmap onto an unmarked trail doesn’t make it legal. Heat ≠ access rights. Always confirm access with the land manager or posted signs.

E-bike nuance: Many trail systems treat e-bikes differently by class (or ban them unless designated). Apps may not consistently show class-specific access—always check posted rules and the land manager.

One Source Has the Final Say: The Land Manager

Apps help you plan, but the sign at the trailhead and the land manager’s page always win. U.S. federal agencies publish e-bike guidance and often rely on unit-level designations and posted maps. City and county rules can be even more specific.

National Park Service

NPS policy enables e-bike use in the same manner as traditional bicycles where traditional bikes are allowed, with local restrictions and designations by park units.

U.S. Forest Service

USFS guidance treats Class 1–3 e-bikes as motor vehicles and allows them on motorized roads and trails. Non-motorized access depends on designation through travel management.

Bureau of Land Management

BLM generally allows e-bikes on OHV-open roads/trails/areas, and permits non-motorized-route access only when a BLM manager issues a written decision authorizing it.

Tip: Apps are helpful, but land managers have the final word. See our Federal Lands E-Bike Guide for NPS, USFS, and BLM context before you ride. And always carry at least one true offline map. Cell signal is not a plan.

Editorial Standards & Verification

What we verify

  • Offline capability and limitations using each app’s official documentation
  • How each platform describes trail status/closures and user reporting
  • Federal land-manager guidance for e-bike access (NPS/USFS/BLM)

What we avoid

  • No claims that override posted rules or land-manager designations
  • No “heatmap = legal” assumptions
  • No price/plan claims without linking a current official source

Disclosures

  • This page is informational and may change as apps and agencies update policies
  • Always follow on-site postings and official land-manager designations

Use a trail app to confirm status and offline coverage, then record with your favorite tracker. When in doubt, the sign at the trailhead is the rule.
