Very informative 4 hour bike tour. Don't let the time on the bike put you off! There are lots of stops where information is shared and small forays into a temple, restaurant for a snack and even shopping! Terrain is very flat, so you don't have to be a super biker - we even had 2 Belgian 9 year olds join us! Tour guide was very informative, knew Singapore history, how the locals live, which restaurants to try out. We actually back tracked some of the route in the afternoon on electric scooters to visit the Asian Civilisations Museum and other areas we passed on the tour, which was awesome!
