dgk02, I believe none of the Trek + bikes has a throttle (99% sure). That is the case for my Trek FX+. My biggest issue is the bike's weight. It alone necessitates the use of power assist level 1 most of the time. That said I do ride with a local club on rides up to 40 miles.
Oldsid, I hope the wife is feeling better and Yumadons, yes the controler is weird in that is shows MPH but will not show distance in miles.
