I live in the Tonghua Street area of Taipei. It's busy and noisy, and some days I get the urge to get out as quickly as possible. Fortunately there is a road nearby that does this. The city very rapidly transforms into a serene village and the road becomes a winding lane through a vast cemetery. You can then either head down into the Taipei Zoo area, and follow the river back, or take the much nicer route through the valley behind the Four Beast Mountains, and back along the Keelung River.
I drew this route as a map back in 2014, but I didn't scan it, and it was framed and exhibited until this year. I'll let the drawing cover the details of the route and the sights here. Please feel free to download and use it (non-commercially). I've put a high enough quality file here: http://imgur.com/rqfEfjF
The route is usually very quiet with few cars and scooters, especially in the cemetery. I guess this is a combination of ghost fear, and the road not really leading anywhere important. I've seen a couple of other cyclists along here, and the road behind the Beast Mountains forms part of a wider Taipei loop. I mapped that on the Hidden Taiwan Map too.
A couple of notes since the map was made. At one bend there are always birds sitting on a wire above the cemetery. A friend of mine found exhumed skeletons on top of some graves here. According to his wife's student this is part of a little practiced ghost month ritual. The ancestors are given the chance to feel the sun and fresh air on their bones once a year. Near to the Nangang Train Station is the Nangang Bottle Cap Factory. This was built in the 1940's. It was used partly as an events venue, and was a good place to view graffiti. The city recently tried to demolish it but got halfway before it was stopped. However it is now mostly destroyed.
