Biking in Singapore's humid heat does not sound pleasant at all.
It's actually really nice to bike in Singapore, provided you can shower at work. I cycled every day for a month along a mix of park connectors (cycle paths) and two and three lane roads. I only had one close pass from a car because on nearly all roads they have a whole extra lane to use to pass you in so if you ride assertively (in the middle of a lane) they just go around you. And the park connectors are beautiful,…
- warm: Sure, no argument here. Very warm..
- fast: No. Maybe. Let's hope that you don't ignore traffic lights: There are so many places that don't even care about bikes (underpasses/overpasses exist, but are hard to reach or less friendly to bikes by requiring you to ... wait for an elevator). You can understand the layout of the city, start riding and you will end up stranded. You will need to backtrack. The city hates bikes.
- safe: Yeah ... No. Singapore is not insane, but it's crazy enough. People don't understand turning signals. Drivers instead like to push into the direction they want to go, expecting everyone around them to follow along. This is, with no pun, in traffic terms a Little India.
I personally am fine to drive a bike here and being a nuisance, but most people don't do that. Literally everyone on the road is an asshole, some of these assholes drive Ferrari, Maserati, Lamborghini or whatnot. You do NOT want to scratch those stupid idiot's cars with your bike.
Traffic in Singapore is a huge and utter mess. Do not ride a bike here unless you're convinced that it's a good idea...
