Hey whats up everyone! Brand new to bikeforums

. So im 15 years old and my birthday is in a month and ive decided i want a new bike. Right now im deciding between a hybrid, and a single speed (fixie). I will mostly be using the bike to ride around town, nothing to hardcore. What differences will there be between the two types? Thanks for any info! Also does anyone know if the SE Lagor is a good bike? And the Khs urban soul?
