Lower Bike Seat For Boyfriend's Bike
To sum-up, my boyfriend got a used bike that he can't ride. For one, the inner tube on at least one of the tires is punctured, but we've ordered replacements (for both, just to be safe), but the other, bigger issue is that the seat of the bike is too high for him to sit comfortably. He can barely get on, and when he is on, he can't brake. The seat doesn't lower any more than it is currently, so we're looking into replacing it.
The bike is a Schwinn, mostly silver and green. The seat itself is black with this sort of black spring-thing just beneath it keeping it elevated. I know nothing about bikes (never learned to ride them), but I want to find out if it's even possible to swap the seat for a lower one or if it would just be more pragmatic to get a different bike.
Thank you for your time.
