Re: Newbie here
Howdy Jruck, welcome.
Given that you will be riding in the dark and the speeds you want, a scooter might be better suited. I in no way mean to dissuade you. motorized bicycles are a blast but as yet do not have adequate intrinsic lighting and even 40 MPH on a stock bicycle is pushing it most especially on a dark road. Sand, potholes, glass can all make for a real bad day that night.
Just my thinking and don't want ya to have trouble commuting and certainly don't want see ya hurt.
But can be done. Post lots of pics on what ever you decide and again, welcome.
