The best way to enjoy the 26km trail is in the evening when the sun is setting over the west.  And the good news - you can rent a bicycle if you do not have one either at
- Punggol Point Park in the north - map link; bus no 84).
 - Punggol Park in the south - map link; bus nos. 62, 74, 113, 119, 147, 74E; 80, 82, 87, 88, 89, 119, 89E, NR6)
 
The map below (click to enlarge) shows you the locations of these bicycle rental kiosks, thanks to Trina Chua from NParks for the information.
Both bicycle rental kiosks are open; timings:
-  Tue to Fri from 2pm to 8pm and
 - Sat and Sun from 9am to 8pm.
 
Note that you have to return the bicycles from the kiosk you borrowed it from, i.e. they are independent of each other.  A leisurely 26km ride with stops might take 3-hours (there is a 15 km/h speed limit), so do plan your ride well - come by the park and rent your bicycle by 5pm if you intend to take in the sights and grab some photos.
Now, get on that bike and ride!
