I took the Gunung Batur/ ricefields cycle tour with Bike Baik - managed to book it at the last minute and it was well-worth the money. Paid Rp350K and got so much food and drink - lots of information and they took us to so many places with great views and free fruit. The group wasn't so big so there was good interaction - excellent safety measures taken and warm hospitality at the end of the day. Wouldn't go with anyone else.
