The guide is amazing! Sympathetic, great spirit and well informed! Only with the route I was not so happy with. I have done tours in Budapest several years ago and there we covered more of the city. So I was a little sad, how little we covered and we were standing for very long times at each spot and getting a lot of detail information, instead of seeing more in total. I personally prefer getting a good orientation and good idea of the city in total.
The tour was ok. Be aware that there is a minimum CHARGE of 50 Ringgit, up to 50 USD (!). It’s NOT a tip based tour. I think promoting it as a free/tip-based walking tour and asking for specific amount of money is misleading and goes against the principle of free walking/tip-based tours. (Even if I do have compassion for the guides, that some people don’t give a fair tips, which is definitely not cool). Also in my opinion the “suggested” minimum amount of 50 Ringgit for a walking tour in Malaysia is really overpriced. The tour guide demanded at least the full minimum price of every person. Wouldn’t recommend the tour.
The tour is AMAZING! Do it!!! You get to catch a lot of different sides of the city, because you are way faster by bike. And honeslty: I didn’t expect it to be this safe and easy to cycle in Chiang Mai’s traffic. San is a great guide. He really overdelivers. His English is very good and his knowledge is incredible. Don’t hesitate and get in the bike! ;-) Few things to keep in mind: better come well fed and stay hydrated. Women may also want to bring clothes to cover up for entering the temples.
