A lot of folks here have commented on the stiffness of the Stromers without any suspension. The carbon fork on my ST2 allegedly helps absorb vibrations better than aluminum, but that's not saying a whole lot. Even though I got a spectacular deal on my ST2 (Thank you Crazy Lenny's!!) I spent more than I had planned. After I bought the necessary little things like extra inner tubes and tire liners, chain lube, a better headlight, panniers and locks, I was out of money.
Lots of folks here have Thudbusters or Bodyfloat seat posts which are quite pricey. Even the less expensive Suntour version isn't cheap. Then I found the Satori Animaris parallel- linkage post on Amazon:

It's gone up a bit in price since I got it, but for the money I don't think you'd find something that works nearly as well. Even large irregularities in the road are smoothed out.
I didn't want and couldn't afford to buy the front suspension kit offered by Stromer dealers. But my hands have been numb since the day I got the bike. Gloves help a bit, but I really wanted a Sta-Fast suspension stem. But they cost a lot. I tried a less expensive RedMotion Shockstop stem, and that was good for minor road chatter. It would probably be fine if it were my only option, But then I stumbled on these suspension handlebars from Baramind (a French company):

They make three different versions: a City version with quite a bit of rise and back sweep, an MTB version with adjustable amounts of deflection which are flat bars, and a Trek version which is halfway between the first two. I got on the mailing list and ordered it last week when they began to ship. It took only 5 days from Paris to Vermont which was impressive, but not nearly so impressive as the handlebars themselves. They are amazing. At $100 they're not exactly cheap, but they're still cheaper than the available suspension stems, and the design makes more sense to me and from my experience, they work better.
For $150 I went from numbness in some very vital body parts to feeling like I'm riding on deflated fat tires, but the handling hasn't changed. If anything, being more comfortable improves how the bike handles.
Stay comfy and wear your helmets-
