Heart and Soul Men's Shed chief executive Terrence Thompson said volunteers modified a recycled exercise bike from the City of Armadale's Drop n Shop, which now uses pedal power to spin a blender attached to it.
"It probably took about a week to develop," he said.
"We had to use a bit of grey matter in our heads and there's not much of that left now."

READ NOWThe unique Blender Bike was created to promote healthy living in the community.
It made its first appearance at the Minnawarrwa Festival on May 3 and was a huge success, with members of the public jumping on and pedalling away to make more than 45 smoothies.
Mr Thompson said volunteers at the Men's Shed were pleased it went for four hours straight without a break down.
