What type of performance should I expect from putting a Crystalyte Brute 48v rear wheel setup on my Diamond Back Hybrid? I weight 215 and my terrain is mainly flat with 2 overpasses (one for railroad and the other is longer for a highway). My goals are for around 20 to 25 mph modestly with little pedaling. I can maintain a steady 16 mph non-assisted. I want this so when I ride to work (7 miles) I'm not sweaty as I sweat like crazy when I ride.

You should meet your goals with that setup.

If you want to cut costs a 36v system will still meet your needs. Just make sure you have at least a 12amp/hour battery. Preferably LifePO4 of course.

For some feedback:
1. The Crystalyte "Brute" 5305 is a hill-climbing oriented motor. If your ride is mostly flat, with just one or two climbs such as your overpasses, you may enjoy a more all-round motor like a "Phoenix" 5304. Smaller, lighter motors are also capable of reaching these speeds without difficulty.
2. Here is a motor simulation program, which has some fairly good data relating to your questions. It should help you to find out what you could meet your goals with.

On the simulator, the names of the 5 series motors correlate to their numbers as follows:
Brute: 5305
Phoenix: 5304
Racer: 5303
As to your initial question, what sort of performance?
The 5305 Brute at 48v would provide a top speed output of approximately 28mph. The torque output on this model at this voltage is quite respectable, even with a 20a controller. A 35a controller would provide exceptionally high torque output.
There are many motors other than the 5 series which could meet your needs, as others have mentioned. It all depends on what you would like to get out of your system - I suggest looking around on ebikes.ca in the motors section, they have some very good resources to look through.
If you decide on an X5... run it at 40 amps to get the most out of it.. otherwise you are better off saving money, weight, etc.. and going with a 4 series and a 20amp controller for easy 20 mph and 25mph is not out of reach either..
The X5's are fun, but they cost more, weight more, need a bigger battery that adds cost and weight.. etc.. depends on what you want to do..
