I already had a cover for the rear half of the bike (by SciCon: https://uk.sciconbags.com/products/protection/wheels/rear-bike-cover ) but needed something for the front half which would fit on the bike with the front wheel off and the handlebars flat with the frame – for sliding in and out of the car boot. This was not available ‘off the shelf’.
So I had a ‘front half’ cover made up by a seamstress (my aunt). I bought a full size black nylon ripstop bike cover from Amazon which she then cut up according to a pattern I’d cobbled together and sewed it.
This was quite cheap way to buy the fabric part of the cover. I did however splash out on chunky oversize YKK zips – so no chance of sticking or splitting. I also reinforced the cover at the contact/wear points by applying Gorilla tape on the inside with a few strategicaly placed bits of foam padding.
I’ve been using it for a couple of years now and it’s performed well – protecting the car and the bike.
