As SW has said, it doesn't take that many minutes to remove the motor if fitting the Stealth version.
Both of my bikes had holes already in the base of the seat post/bottom bracket area, so I was able to run the hose straight through this, then just used the existing holes where the cables run. No drilling, and no hassle.
Both of mine were the 2015 version which were bought at discounted price, and both have a right hand remote that is fitted upside down to the left side of the bars. It keeps the installation much neater and tidier.
Note that I said were fitted with the 2015 version. One of them only lasted about 30 miles before blowing an internal seal. It was replaced immediately under warranty for a 2016, but it was still hassle having to do the job twice.
On the plus side, the 2016 version does feel very refined.
You will need to know your seat post tube diameter and correct length before ordering.
