The bike blender runs on a dynamo on the back wheel and after a half a minute of vigorous pedaling you are rewarded with a delicious smoothie. Best healthy recipe is frozen bananas slightly thawed, a few frozen berries and milk. Pre peeling the bananas before freezing makes life easier. Available for loan in Christchurch for a donation or you can buy one for $200 which includes a new blender jug and new pannier rack which can be attached to your bike. Its best to have a 26” bike with slick back tyre and if you want kids to use it, a small frame or woman’s frame. You also have to supply the stand to mount the bike on - old wind trainers are readily available. The jug must be held in place by a second person or it will fall off. You could organize a strapping system to hold the jug in place but at events where lots of people are making smoothies its easier to get it on and off quickly with no straps.
