I have had my Peugeot Urban Express for almost 25 years. It's still in good condition. Due to the fact that I am now 25 years older I've realized the handlebars need to be higher to reduce stress on my hands. But I can't get them to budge. I've loosed the nut on top and hammered down on it with a rubber mallet. But the bars refuse to move in any direction.
Would love any suggestions.
