How to get around Siem Reap and Angkor Wat on a bicycle

While most tourists in SR tend to take the Tuk Tuks to get around, I found biking to be waaaay better if you're not in a rush
It's only 6km from the city centre where your hotel is probably gonna be to the cluster of temples around Angkor Wat. Took me about 30 minutes to ride it
It's also cheap: I rented a pretty decent mountain bike for around $11 usd for the whole day. You can get a "shitty" bike for $2 a day. Your hotel may also have some bikes on loan so ask them first
Arrange it the day before you plan visit Angkor Wat. You should go check out the sunrise at Angkor Wat (even though it's gonna be packed with tourists), and no shop is open at 5am when Angkor Wat opens
Bikes are readily available. Just walk around the city centre and you'll find a bunch. I used these guys called Aing Kimsang as their shop looked legit and the bikes were in very good condition. I know there's a non-profit bike rental company called The White Bicycles that supports local education and clean water initiatives and their bikes are cheap ($2 per day), but they don't have good quality mountain bikes
Road condition:
Siem Reap is flat, very easy to ride
Roads are narrow, and there's no bike lanes.
Traffic can get crazy. You'll need to learn to be a bit aggressive especially when making turns. But I haven't seen other cyclists getting into accidents so don't worry too much about it. I got the hang of it after about 30 minutes
Lots of trees cover and shade once you get to the temple area
Other tips
It's hot. Bring lots of water and dress very light
The bike shop will give you a lock (mine did, so). At first I tried to find rack to lock my bike to at the temples, but after a few unsuccessful attempts I just locked the wheel and that's that. Didn't have any issues. I've seen some bikes locked against the fence, so you can try that as well
