I test rode a 2018 Trek CrossRip+ mid-drive a couple months ago. It only offers assist, and requires you to pedal. The best part of this eBike is that it dramatically reduces the stresses on the knees when taking off hard from a stop. Was considering getting this eBike for my wife, so it can bridge the power gap between us, while I ride my aBike (analog bike). After the test ride all I could think about was whether I could borrowing it, raise the saddle, and maybe put on an adjustable stem so I could stretch out the bars (she's 5'3" and I'm 5'10"), so I could use it to make my 15 mile commute every day of the week, even when my legs are sore from training hard the day before. Unfortunately she seems to want an upright hybrid, but I want her to get an aero drop bar, for my own selfish reasons. We are now at an eImpasse.
