DIY Waterproof Oilcloth Bike Seat Cover

DIY bike seat cover tutorial oilcloth

Last year, as a birthday gift to myself, I bought a vintage women’s bicycle. A green, 3-speed, Raleigh Sport, made in England in the 1970’s. It’s crowning glory is it’s leather Brooks saddle seat!

My bike is a prized possession, but it’s also a functional one! What good is a cool retro bike to anyone if it’s just sitting in a garage gathering dust? Since I do ride my bike around, I try my best to keep it protected and in the best condition possible. So, I decided to craft up a cute and fitting waterproof cover for my seat, to keep it protected from the rain and sun.

I used a fabric called oilcloth, which is waterproof, inexpensive, and comes in tons of cute patterns! If you’re making one yourself, you will also need some nylon cord, a sewing machine, and some plastic cord stops (optional).

Trace around the top of your bike seat and cut out a piece in a matching shape. Then, using a piece of yarn or string, find the length around the outer edge of the piece you’ve just cut. Cut out a long strip of oilcloth measuring that length by about four inches wide. Cut that strip in half lengthwise.

Working with one strip at a time, pin the edge piece to the top piece with right sides together and stitch around. Join at each end with a straight stitch. This can be a bit tricky since the oilcloth is somewhat stiff, but just take your time!

Turn right-side out, then fold down about three inches of the edge strips all the way around, pinning down as you go. I did this based on the shape and size of my own bike seat, so you may want to slip the cover over your own seat at this point to double check how much to fold over. Stitch around where you’ve placed the pins, creating an open canal for the drawstring to thread through.

Cut two slits in the back end of the cover, on either side of the back seam. Then, using a safety pin as your guide, thread the cord all the way through.

Use a lighter to melt the ends of the cord slightly so that they don’t fray. Here you can add two small or one large cord stop if you like, or you can simply tie the cords together.

Slip the cover over your seat, pull the drawstring until snug, and off you go! Rain or shine, you and your bike will be happy and looking fly!

I have some extra oilcloth leftover, so maybe I’ll make a matching storage pouch to attach to my handle bars!
