bike bodge #2- no pump

You need air but have no pump, or a broken one. Answer- beg or borrow air from an inflated car tyre. Tape two connectors together and connect the car valve to your bike valve and use the escaping air to inflate your bike tyre. Even works for inflating a car tyre too. If you have a single connector its harder but using plastic bags and tape try and seal the gap at the other end between the bike valve and the wrong end of the connector.
