Hello, just new here
Since I have a limitation in my legs (partial paralysis) I am looking for a carbon e-gravel bike.
Searching a frame to mount a Bosch Performance Line CX motor (85 Nm) or other, because I need this sort of torque.
In addition, it is important to have a 31.6 mm seatpost, so that I can mount a dropper post of at least 150 mm with control on my thumb, because I cannot stand on my toes.
Electronic shifting is preferred (Shimano?)
I would be very happy with a solution.
Thx a lot,
Luc (Belgium)

I seldom run across a carbon gravel E-bikes on Aliexpress. (Some offerings if you are looking for a Carbon Hardtail 29er E-bike frame.)
Look at Light Carbon Bikes or 4leaf. (Majority of Chinese offerings use Bafang motors, rather than Bosch.)

Chinese electric bikes are the next frontier, and still elusive every time i check. Sourcing integrated motors & batteries is a problem, there's usually high MOQ. Obviously sourcing suitables frames isn't easy either, but it's easier than sourcing the right motor kit. It gets expensive, too, so for something with a lot of unknowns, it's quite a commitment. For what i need the bikes to do, i also need a jail broken software because an electric bike maxxed out at 25kmh is entirely useless, and that is also a problem. I'd build road bikes for girlfriends and slower guys to ride up to at least 40kmh, so we dont drop people.
The only practical route i know of that involves not buying something off the shelf is a bafang kit on an aluminium frame (you risk crushing the BB area if it's carbon). JohnnyNerdOut is a great resource on youtube.

The only full e-gravel bike I came into is the 4-Leafs e-gravel complete bike from their site last year, full carbon -egravel with mid-drive bafang motor and chinese groupsets. Asking price was usd$2500. But that bike is no longer on their site this year.
