Got the bike last week and it is extremely well built and runs like a dream. I also backed the original AM bike (Step+) back in 2018 that I (well, my wife) have been very very happy with, however there were some things that could make it even better that I believe have been implemented in the AMX. The wider tires is a very good addition when you ride with full battery support (25+ KM/t) and it feels more sturdy. The “gear/support” changer is also much more well thought through. Easier to get it turned on and change battery support level while riding with a single hand. The integrated lights connected to the battery is so obvious it’s surprising it was not already implemented in the original AM bike. The front fork seems/feels also much sturdier. The way the battery support kicks in when you start up your ride is a lot more smooth than the original AM, and you don’t get the same “chock”/tailwind as with the AM. I do, however, find that when you hit cruising speed with e.g. Level5 battery support, the way the motor “stops” supporting is a bit abrupt. It simply feels “wrong”.
I do miss the handlebars with integrated basket that was on the original (this I believe was not an option for the AMX)
All in all, this is SUCH a nice eBike. I would buy again.
