I really rate the bike parka one I've had for a year and a half on my bullitt. Super light, easy to put on/off, zero issues, no hint of rust at all and it's been in my front garden the whole time.
Yeah was looking at these but they’re sold out or due for delivery end of August. I picked up an XL Oxford motorbike one for now but might look into these as they look better quality
Recommended rain cover for cargo bike?
