Attaching moto seat to custom frame ebike

[Ohhmyvaler]

Hi Folks

I need some advise from someone who messed up with a welder once or twice

I have this 1/2 fat bike which I’m quite happy with
(Ignore the front wheel it’s a temp solution- original wheel does not fit the DNM fork, so I’m working on it.

All good but the seat is a giving nightmare and I do commute around 35 miles daily.
I’ve picked a seat for KLX250 from AliExpress and I’m trying to figure out how to get it on the bike.

This is the frame close up where it needs to sit

And that’s the seat from the bottom



I was thinking to weld a few horizontal steel bars to support it, what do you think?

The final result is going to look like so, I’ll trim the seat from the front and back just a tiny bit to make it “pretty “

Roast me!

Is it just me or is your original seat and bracket mounted backwards?
