Are you close to the shop where you bought it? From what you wrote, it sounds like your knees are hitting the handlebars. The riser, that long thing between the fork and the handlebars, should be able to be lengthened. Check with your shop about this. That way, the handlebars would be higher as you bring the bars back. You have to be careful not to bring the riser out too far. Maybe you can contact Easyracers or Sun and ask them if there are marks on the riser for maximum extension, like a seatpost on a bicycle.
