I know this thread is a year old, but I figured I'd add my 2 cents worth anyway. I own the Phantom X2. Here's why I bought it. I wanted a sturdy and tough E-Bike with no frills. I wanted to pay under $1,500. (Actually, my wife set that stipulation) The Phantom X2 fit my criteria. I purchased my bike from Crazy Lenny's E-bikes in Madison, WI. They are amazing to work with!
I use my bike to commute back and forth to work if the weather cooperates. My commute is 14 miles round trip. I always pedal along with the bike, and I average 19mph. I can get two trips out of this bike no problem. Keep in mind, your mileage may vary. I'm a 5' 10" 160 pound guy, so keep that in mind. I have had no problems with this bike, but I feel I use it for what it is intended for. It has a nice front shock, but I would never take this bike off road. I feel the front shock is more to make the commute more comfortable. You do feel the extra weight on the back from the battery, but it has never bothered me. The one and only thing I don't like is having to hold the throttle for the entire 7 miles. My hand sometimes gets sore. Fortunately there is now a pedal assist device available that I plan to add.
If you are looking for a good bang for the buck E-Bike I would take a look at the Phantom X2.
