Taking over an unused bicycle from friend.

I wanted a bicycle for basic use as I dont use often and buying a brand new foldie is very expensive. Asked around and a friend happened to have one that is no longer in use. Was informed that the bike has not been in use for a long time. (Rather when we received it, wasnt able to use). The joints are all stiff and requires quite abit of saving. Happy with the use of wd40, the joints are now smooth and can now be adjusted to suitable height.
