After best experiences with larger Ortlieb panniers, these are ideal in size for shorter trips with the folding bike. Absolutely waterproof without additional protective covers as with other manufacturers and very stable. Are thus also well suited to pad the trunk so that the folding bike stands firmly. The attachment to the luggage carrier and its adjustability is solved even better than my older bags. There may be cheaper, but probably no better panniers. Am very satisfied and would always buy again!
Small but perfectly formed, they really help balance the bike. Before if I rode with the rear bags and a handlebar bag, the bike wheelies very easily, but also made the steering quite a lot harder to keep in a straight-line (because of the higher weight in the handlebar bag). Having the weight down low (low-rider) makes a lot more sense. There's a reason what this configuration sells: because it works.
