>>1209976super cool.
I don't blame you for wanting more gears since your commute is so long, but I agree with the other guy about annoying-to-find french parts and from what I understand Peugeot has both good and crap-tier bikes, it is not a quality brand in-and-of itself so you have to research the models.
The original look is smooth as fuck but there are some practical upgrades I'd personally make i.e.
>nicer, lighter platform pedalsmaybe with some pins for good grip in wet conditions.
>treking or butterfly bars or some bar-endsfor a more forward position when you want one, useful for speed, climbs, and a mild aero position in high wind
>maybe a different saddle and postsaddle looks like it may weigh a lot but if you really feel that saddle fits you, don't touch it! that post looks like it's heavy-as-shit steel, an alu one is an easy upgrade and I find modern 2-bolt designs are just way easier and faster to dial in adjustments, especially small increments.
However, once you buy quality upgrades you may as well have invested in a whole bike like you say. $150-$200 can usually get you something great if you know what to look for (or use

either way I love that bike.
