My husband and I try to do a bike tour in almost every country we visit. However, I am not really a comfortable bike rider otherwise (we live in NYC, my husband will bike, I do not). So I really don't go biking that often. That being said, this was one of the more challenging bike experiences we've done but I still enjoyed it, would do it again, and would definitely recommend it! First, our guide Sunchen was phenomenal. He was so kind, so accommodating, and was just a pleasure to spend an entire day with. He went at a great pace, and knew so much about the sites we saw. At one point I lost my sunglasses and he went back (it was quicker for him than for me or my husband) and found them so quickly when it would've taken me so long. He was so great to speak with and we really enjoyed speaking with him about his life and experiences.
The bikes are in great condition. First, he led us to a great spot for the sunrise at Angkor Wat. We actually ended up being the only two people on this tour! So it was a private tour for us, which is amazing. Either way I'm sure he could've handled a larger group. After Angkor Wat we went and had an amazing private breakfast with a private chef making omelettes, toast, fresh coffee/juice. Then we headed on our way. Most of the paths are very easy and flat. Some of it is a little more tricky but, again, I was able to manage. At one point it did start downpouring (we went during rainy season) and Sunchen was able to navigate us around the super flooded parts.
We had done two days of tuktuks and not only did Sunchen skip parts we already saw so we could spend more time at newer (to us) sites, but he also took us along the back roads/bike paths that you couldn't go on tuktuk or simply walking. We saw some incredible sites we could not have seen without this tour and it was such a cool way to see everything. We met up with our driver a few times for snacks and breaks, and just had a great tour overall. If you're not horrible on a bike and not afraid to get a little dirty (and I wore white linen pants so you'll be fine!), you should absolutely do this tour.
