Well maybe this is an option and you get another use for your bike pump; making an espresso with your bike pump. Not sure if this product is actually on the market or not. If you know do let us know via the comments section.
Well this product does not look that polished so a bit of search online brought up the Handpresso Wild Ground Espresso Maker but it has an Australian price of $200!
The operation but does seem rather simple â€¦
you pump it just like a bike pump to gain pressure, add hot water and real ground coffee. Then press a button. This is followed by the coffee emerging, a sudden ‘sphssssh’ sound and a final layer of crema. Magic
