The Domane + is fabulous. You might be surprised how well it handles. I don't find the weight troubling, and that is after years of riding a 17 lb Specialized S-Works carbon Roubaix. My only complaint is the drag of the gearing at low speed when the motor is off. Once up to speed that is not an issue, and I usually turn if off on flat ground, but it does make it hard to climb significant grades at lower speed with the motor off. For anything at more than 6-8% it doesn't matter to me as I have the motor on (otherwise I would be on my Roubaix), but lesser grades are a chore. But by using a Nyon I have custom modes that can add just enough assistance to neutralize the gearing resistance on lower grades. I think that is critical, and I would never buy a road e-bike (and this is my second; I had a Haibike Race S 6.0 for 1 1/2 years) without the ability to customize the assistance levels. The standard levels with Bosch motors are too high for most fit road bikers.
One of the things I like about the Creo specs is assistance up to 28 mph. I read many road bikers saying they don't need assistance at speeds greater than 20 mph, that they can ride at those speeds without assistance. I would respectfully submit that most of those folks have not ridden a bike like the Domane +. Yes I don't "need" assistance then either--I can ride even the 38 lb Domane + with the motor off at speeds in the low to mid 20's mph range on flat roads and frequently do. But the fact is it is just dang fun to ride at 28-30 mph using assist, either to move with traffic coming back from my ride through urban areas or as today when coming back on the windy roads after climbing Mt. Tam north of San Francisco. It's also great in the strong headwinds that can be common here especially along the coast. In my view once one has experienced that the benefits outweigh the disadvantages of the bike weight.
