First, the price was very expensive, a 2 hour tour for one person costs P1,200.Despite charging such an amount, Bambike DID NOT ACCEPT CREDIT CARDS. As a result after the tour there was a long line of people at the ATM right outside. Second, the bikes were very badly maintained. Some bikes have broken brakes, others have seats that are falling apart. Third, Bamboo bicycles are just plain bad. They are not "more eco-friendly". A regular metal bike is just as eco friendly, since most are now made with 100% recyclable aluminum or metals. A Bamboo bike is less stable, in contrast to a regular bike, bamboo bikes do not absorb vibrations well, so its a very uncomfortable ride, this is exacerbated by the bad roads of intramuros. Fourth, the tour guide we had (I wont mention the name) was just plain WRONG a number of times. When I called him out on his mistakes, he would simply make excuses saying "I must know it better since I went to a better school". On every tour I expect the tour guides to be EXPERTS on their subjects. My guide on this tour was not only wrong, but masqueraded as an expert. Fifth, he presented his own opinions and political views as historical facts. I had to go up to each and every person on the tour to explain to them that the tour guide was already making mistakes, and mixing up fact and opinion. Those that rated this tour highly, I think are foreigners that wouldn't know that they are being fooled.
Take it from a local, this tour is misleading and not worth it.
