I bought a bicycle, unassembled, and found stuart on gumtree. He charged me $70 to assemble my…read morebike. He asked me to try it out, so i went around in a small circle and said i thought it was fine. He left, with my $70. When i rode it to work the first time the gears wouldn't sync, i have 3 out of the 6 on the lower cog, and one of those keeps jumping out. Then, my back brakes went from ok to nonexistent and my front brakes were no better. I txt stuart the problems, asked him to come and fixed them, without paying another $70, and he txt me back to tell me to call him after work and HE WOULD TELL ME HOW TO FIX IT....Yes, that was his response, i have the txt on my phone. Im not a bike mechanic, i have no tools, arthritis in both of my hands and i am on my own. How on earth Stuart thought id be able to fix these problems by myself, is beyond me. Very unhappy. Cant ride my bike, cant get it to someone elsr to fix properly, and shouldn't have to.
