I need help buying an inner tube online. I have a Scott e-bike with 28×2.00 tyres and Presta valve. I live in UK and I'm very confused by the options.
I have attached a picture of the tyres and one of the options I see from a local online shop for a Specialised inner tube with Presta valve.
Please help me understand.

Since your tire is 50x622mm, I’d go with the 700×32-50C. 700 is the same as 622mm, the latter number is width in millimeters. They’re just different standards.
You have 29*2.00 or 700*51 mm tyres, as they’re 622mm bsd. None of the tubes listed fit. Ideally go into lbs (local bike shop) and they’ll give you what you need
I’m just gonna say it’s wild that the bike industry hasn’t figured out how to make this process much, much easier.
