I have a Raleigh Sprite that I got as a project bike but I've got to part with it, I've got too much on the go at the moment. It needs some adjusting in the bottom bracket and headset which is pretty easy to do at Bike Pirates or Bike Sauce. The bike needs a rear wheel and would be a perfect single speed. I've taken off the derailleur and shifter to make it a ss but they'll be included in the purchase if you wanna throw a 3 speed wheel on the back instead
with a bit of work you'll have a great summer bike
