Aluminum Rear forks & Torque arms

Hi Everyone
I have been planning on installing this kit, http://ebikes.ca/store/store_ezee.php It is a rear wheel, 26", # 400 watt internally geared eZee brushless hub motor laced in a double walled rim
# A 180mm disc rotor
Was thinking of going with this battery 37V 14Ah Polymer pack, or even to a 48V battery.
Now I go an check the bike ( Marin, Coast Trail) and find it all aluminum, a magnet does not stick at all, anywhere.
So, question is, 1. For a Rear Wheel Kit is it a real no no, to install this on an aluminum frame?
2. The torque arms just mention Front Wheel, guess there is no torque arms for the rear?
3. Could I, or should I use the Front Wheel Torque Arms on the Rear?
Hate to spend almost $2000, and find I can't this kit together, kind of a NOOB here,

Aluminum frame for a real wheel hub should be fine. Torque arms are cheap so I'd use one just to be sure. They are about $25. Actually, I don't know of any rear torque arms or if you can use front ones on the rear because I've only had front wheel hubs. That's a really good hub motor and I've heard it's very easy to pedal because it's a geared motor.

Some people with rear hub motors have used the universal torque arm sold by Amped bikes. Some have used one sold by ebike guy. Here's a photo of the one sold by ebike guy.

I have an EZEE rear wheel kit installed on an aluminum mountain bike and it works great. It has a 36V 10Amph LIPO battery. I have over 1500 kms on it now with no problems. I don't have a torque arm just the big nut supplied by EZEE.
