Don’t make the mistake of riding without a simple bicycle repair kit. You need a pump that attaches to your bicycle and a small seat bag you can strap beneath the seat. In this bag, put a spare tube (same size as what’s on your bike), tire levers (use them to remove the tire), patch kit (in case you get two flats), and a mini bike tool and perhaps some cash, just in case. Even if you don’t know how to use the stuff, the kit can come in handy because a cyclist might come along and help you out (other cyclists love to lend a helping hand).
