Hi Alex,
While Map Maker is not yet open for editing, you can report this as an maps issue on Google Maps. In Google Maps, zoom in to the location where bike paths that you know well are obvious on the map but don't show up.
1. Right-click and select "Report a Problem".
2. From the "Which element is wrong" drop down list select "street".
3. Describe the Issue.
4. You can check the "Email me when the problem is resolved" check-box to be notified about updates on the issue.
5. Click the "Report a Problem" button to submit.
Regards,
