My Fiido Titan ebike came with Dyisland 4 piston hydraulic brakes fitted. The brakes are really good, but Fiido swapped hoses over for UK market, resulting in them being too short for safe use. I ordered 5m Dyisland hose and fitments to make up hoses long enough to raise my handlebars and allow free movement in steering. The items arrived very quickly and well packaged.
When set up correctly, Dyisland hydraulic brakes are very effective and match the quality of much more expensive brakes. The brake sensor for motor cut off and brake light initiation also works very well.

I recommend Dyisland products and will be buying consumables from them for the life of my current bike.

DYISLAND Brake Hose

I modified my brake lines to accommodate higher handlebars. I found the Dyisland components easy to work with and they appear to be durable and reasonably high quality.

So, typically when you are able to replace a hose you also have the tools to put the olives etc. on it, so I’d prefer an option where the ends are not preinstalled so I could cut it to length.
