Needed a water bladder for a new Evoc bag (didn't come with one), looked around for one, everywhere was way too expensive, saw Biketart and thought lol thats a great name for a company. Was around £10 cheaper than another big bike shop that sucks (not naming names, but they are owned by Halfords).

Super happy with the product, my only gripe is that Evoc assume you know how to open the bladder to fill it, took me about 10 minutes to work that out, I nearly ripped it apart in the process - I have left a negative comment on Evocs social media, seems I'm not the only one without a masters degree in 'opening a water bladder'.

Again, Biketart are a great service, with a great name.
