Just Bought a Cervélo S3 – First Time with Electronic Gears, Need Help!

Hey everyone,

I just bought a Cervélo S3 from BuyCycle, and this is my first time using electronic gears. After some searching, I think I’ve found the charger (near the handlebars?), but it doesn’t seem to be charging.

I’ve tried shifting gears, but nothing happens—it’s like the system isn’t "on" or there’s no power. Does anyone know what I might be doing wrong? How do I check if the battery is actually charging or even has power?

Would really appreciate any tips to get me started!
