They had several models available to demo... not sure exactly which ones because I was focused on the Crossrip+ and the Super Commuter+ 8S. Took them both for a spin. My first time riding an e-bike. That first pedal stroke in the parking lot was magical

. Barely touched the pedal and off it went.
They are both great bikes, and I preferred the Crossrip+, but I was already biased toward it based on everything I read. My personal preference is the drop bars, and the test rides confirmed that it's the right style for me. My main motivation in considering an e-bike is all about speeding up my commute to work. I would say that being down in the drops is marginally faster at high speed... it's just a little bit easier to keep it in the 28mph spot. For me, it was a little unsettling in the upright position at those speeds because it just felt like I was exposed to the wind a bit too much. The Super Commuter is more relaxed and comfortable for casual riding... the Crossrip+ fit my more aggressive style.
Great bikes, and the Trek folks were friendly, knowledgeable, and helpful. Now I just have to decide whether to spend the money or not
