Issues with front hub motor on aluminum shocks.

Are there issues with mounting a front hub motor on aluminum bike with suntour shocks. Would regular torque arm work?
The bike is a Specialized step-thru. My other bike has a rear hub motor and it is such a complete hassle to change flats!

I bought this battery pack for my hub motor ebike. I am guessing that the red and black bare wires will connect to the

Re: Are Scooter LG 36V 4.4AH battery packs good for Ebike?

When I measure the voltage at the XT-60 connector, it reads zero volts but when I measure on the circuit board, it reads 34.9V. Does this mean that the BMS has cut off the power? I'm going to try charging one of them with my ebike 36V charger to see what happens. I bought six working packs from ala...
