This week mine was homemade soda. Fermented sodas, citric acid + bicarbonate sodas, different juices and flavors like lime + lemon + cherry and pomegranate or mango peach or cola (homemade knock off)
I already have a pair of nice Road Bike and MTB, which I have neglected for a while. Now I want to buy a cheap MTB in OfferUp to convert using one of those bafangs wheel hub motors.
I don't need another bike, but it would be nice. Let me know of your progress/setup. I think I'll jump on buying once I find a good candidate.
