Embarassing to say that after cycling for over 10 years i still don't know how to fix/replace punctured tire. Just came back from exploring Zhenghua park connector & Pang Sua connector, rear tire punctured on way back at Bukit Batok. Press ahead at slow pace with squeaking sound that's embarassing as well.
Rim is damaged anyway as is uneven on this old old clunker 1st bike of mine. Road bike i bought was stolen a few months after. Thief cut away the cable. Heartache at that time as it cost me $2k+.
Zhenghua park connector has a couple of steep slopes & narrow paths. It runs parallel to Bukit Timah Xpressway for some parts & the sound of vehicles from xpressway disturbs the peace. Pang Sua connector is 1 of the better connectors in the west in terms of scenery.
