Welcome June

You'll find reasonably priced hydraulic brake sets on Amazon, Ebay, and AliExpress.

Just do a search for Shimano Hydraulic Brakes and you'll find sets like Shimano's MT200 for about £75 and equivalent sets from Clarks for about £60 - sometimes a bit cheaper.

These come ready filled with mineral oil: Generally, the hose lengths are quite generous. On a short/small ebike like the Onebot S6, you may need to shorten the hose(s) for which you'd also need to buy a cut and bleed kit and mineral oil to refill the system. Ditto if the hoses need to be routed through the bike frame internally.

The other thing you need to consider is that mechanical brakes on an ebike usually have safety cut-outs to cut power to the motor on the brake levers. You generally don't get that with hydraulic brake levers unless you add them.

There is a lower-cost alternative that also avoids the fitting issues above which I'm currently trying on my own Fiido 20" folding ebike. You can read about my exploits here.

Why is it that you feel you want to change your existing brakes?

Cyclebuddy, thank you so much for the info and I just read your threads regarding the callipers alone and not going to full hydraulic system!!!
“Why is it that you feel you want to change your existing brakes”
I have another bike with hydraulic brake system and I always want that feel and it works really great compare to mechanical system on my Onebot S6.
Maybe I will try replacing the callipers for now with the hydraulic ones and see how it goes. And also I don't want to mess about with the safety cut outs. Will keep you posted and you again Sir!

The zoom hb100's look like they are worth a shout for the money.

Will definitely order online and thank you for the support Sir!
Don't do anything rash just yet. The Jury is out at the moment as far as I'm concerned. Neals predictions on the other thread are bang-on the money... but I'm not totally convinced.

I'm comparing to full hydraulics on my other two full-sized e-bikes. I've only just bedded these HB-100 calipers in today. I'm going on a full ride tomorrow and will update t'other thread early next week and tell you why!
