My joints can't take daily riding in the "typical" efficient biking position. I have to sit fairly upright.

On my last two e-bikes, I have replaced the stem AND the handlebars, for a total of 4" of extra height. However, the Serial 1 handlebars have the brake lines routed inside them, and the stem looks non-standard - very large and square. Perhaps I was just looking at a stem cover? I can't find a manual online, and the assembly videos show that the handlebars and stem come pre-attached to the bike.

I went to the local Harley dealer, and they say they don't have a manual yet, printed or online. They also didn't want to take apart the stem for me to look at. I did note that the handlebars are higher than the seat; probably because this is more cruiser/commuter oriented. My last two bikes were mountain bikes where the handlebars seemed to be at the same level at the seat. So maybe I won't need to raise the handlebars...but it's hard to tell, especially since the shop didn't have the bike in my size.

Does anyone have access to a manual, or a bike you can examine the stem with? Thanks!
