Research, research, research! I'm at the point where I am telling the bike shop guy what the thing does. ;-) Of course, he admitted he was not the e bike guy so my rides yesterday allowed me to eliminate the Trek. I was surprised to find their bike just did not seem up to their usual state-of-the-art design. I also found out at the Specialized dealer in this bike centric town of mine carried e bikes for 5 years. He emphasized "carried" as they had them in stock but did not sell any. The only one they had was the super bad, mountain fatty. Not for me. So I guess the Northern Colorado market has not caught on... if there is one. I told a friend I thought e-motor bikes would be like power windows and locks in a car before long. But that same bike riding friend's spouse's first word was "slacker." She's just that way. Criticizes everything and everybody at every chance she gets. But I digress. I want to try the Yamaha system. Your points above, gents, point to the Yamaha as it has the "instant on" feature that they are claiming sets them apart. Gotta drive to Denver for that. I do want to try the Easy Motion Evo Cross that was, amazingly, not charged up, at the Longmont Small Planet shop. Maybe their sales have been that slow, don't know. Really liked the EM Evo City that I tried. Very upright, soft seat. This had the throttle. Plenty of assist going up the test hill. Easy to read/see the LCD, which is a big deal for me. Some I can't see at all. I like the Yamaha system for that reason. Sometimes its the little things. It will all have to wait awhile, though. Cataract surgery tomorrow. Hell gettin' old. ;-)
