Hello!

I got a BTWIN RockRider 540 some years ago and use it for some light trails, but nowadays mostly just roads. My region is very hilly and has multiple >10º hills, which are perfectly fine for cars, but not really for bikes 😅

Since I’d like to start doing more things in the city center (which is itself also on the hilly side), I was considering either getting an e-bike or converting mine. I’m more inclined towards the latter option, since I really don’t need another bike (already have an extra all-terrain bike for trails and a vintage road bike), it would just be a waste of materials and, from what I understand, money. I’m really not sure where to start looking for appropriate conversion kits, so thought to ask here :)
My budget is flexible, but I’d like to keep it under 200€.

Any comments are appreciated!
