Hi Warner
I have a Smarta LX. Although these is same brand I am not sure how closely related it is to the GT. The LX ia a front motor step-through with a hub gear, the GT is a rear motor step-over with a derailleur. I cannot praise the LX highly enough. In 3.5 years it has done over 14,000 miles without any fault. I am now on my second battery - the original stiill manages 15 miles - and tyres, and third saddle, but everything else is orinal. This is a comfortable (except saddle ), robust and well priced bike. On the downside it is heavy and the motor noisy.
To sum up, if you want a serious commuter, you'd struggle to find better.
