Quickest way to get a bike flat tyre fixed in Oxford Watch
Barring that, where could I buy spare inner tubes and a bike pump?
I am sure plenty of students in Oxford have this issue, what did you do?
If you're in North Oxford, the bike shops on Walton street will fix it for 15GBP. If you insist they may be able to do it while you wait.
Apparently Bike Zone on St Michaels will sell you an inner tube and pump pretty cheaply.
Also, if you like being prepared, a bike pump is 3GBP delivered on Amazon, and an inner tube is about 4GBP delivered. You may need those plastic splints to take off the tyre edge easily, those are incredibly cheap as well. I've stocked up, so next time it happens it shouldn't be as much of a hassle.
