I’m in the process of rebuilding my gravel bike it’s a Canondale Caadx with hydraulic disc brakes. Thinking of a midrive system. Has anyone converted such a bike.

I would watch doing any Cannondale as their bottom bracket shell isn't BSC THREADED its a totally different bearing system so while i expect a skilled bike engineer could work his way around it it wouldn't be a job for a pilgrim.. and if you are looking a fitting a mid motor be aware that in both the popular motors the bracket outer shell has to be flat with little or no swelling or plastic/nylon brackets eg to guide and control gear inner steel cabling.. how do i know... called experience.. have done 25 to date the 26th didn't work mainly because Whyte had swelled the bracket to allow internal cabling and hydro hose to come through...

Hydraulic brakes - how do you plan to connect the brake cutouts?
I guess the battery options are downtube or a frog fitting? Any thoughts?
What size are your rims? 26"/700c rims are common, I was told 29er rims were same diameter as 700c but wider (but I've not confirmed)
Not relevant if you go for mid drive, but for info rear drive might be tricky - the alloy framed bikes I've looked at often have very shallow rear dropouts so making the axle & anti-rotation bits secure needs thinking about.

I've not tried any mid-drive conversions so I'll let others give suggestions about that area :)

Most (not all) mid-drive systems are torque sensor, so no need for brake cutouts.

It's easy to find adaptors if you do need them. eg
or you can probably find them cheaper elsewhere or even make up your own.

Use the e10 chain for electric bikes and you will be fine with your 10-speed. I have done 30 or so such conversions. Yours will be better than new eBikes from stores. You will likely want to mill the inside of the bottom bracket shell to remove burs. You have a beautiful bike!

https://www.aliexpress.com/wholesale?catId=0&initiative_id=AS_20210225012913&SearchText=ebike+hydraulic+brake+cut+off Hydraulic brakes have a different power cut off than the normal kit so you would need to either chose a seller that will sell the option or buy separately.

Going mid-drive because? ...
