The latest bike blender has a stainless steel frame with a friction wheel rubbing on the tyre that turns the blades of a blender at the front of the bike. There is an oversize chain ring so you do not have to spin the pedals at quite such a manic pace to get the perfect brew. It takes about half a minute of vigorous pedaling and you are rewarded with a delicious smoothie. A good healthy recipe is frozen bananas slightly thawed (nice and creamy), a few frozen berries and milk. Pre-peeling and cutting the bananas before freezing makes life easier. They are available for loan in Christchurch for a donation or you can buy one for $1400 (some options for reducing cost available).
