Thanks everyone for the feedback. In speaking to someone at the bike shop yesterday, an opinion was shared that the difference between a bike like the EVO Race and the Stromer ST1 is that the Stromer would be a much more solid and comfortable ride, versus the BH which would feel every part of the road, especially on the thin tires. So from what I gather, even if I got close to the same speed from the Evo Race, the ride would be much less comfortable, and for someone like me who has a long commute, this seems a considerable issue.
As for the Nitro series, what stands out to me in comparison to the ST1, is that the MSRP is about the same, yet the Nitro has a much lesser battery. One positive seems to be that the Nitro has the throttle, where on the ST1, you have to hold the stupid button to throttle (for the life of me, I cannot understand why the make of such a greatly designed bike, would make a throttle where you have to hold the button on the display, instead of a real throttle).
