There are a lot of differences between the 2019 model ebr reviewed and the 2020 model for 2020. Motors seem different as 2020 they say goes only to 18, versus 20 mph for the 2019 Sondra (sp ?) motor. The 2019 model had fat 4 inch tires while the 2020 has narrower tires without reflective strip or reflectors. Imagine the 2020 model is lighter. Lot of other differences. Pluses for 2020 is adds back rack with rear light and better, bigger front and rear fenders. Perhaps better Vela saddle. Also 2020 you can access full throttle at any assist level and has a red on and off safety button for shutting off motor. The 2020 seems to have inferior front fork compared to 2019, as well as other changes listed above. Both have 10 amp battery. Perhaps these changes (less powerful motor, thinner tires, inferior suspension fork) explain price difference. Of course, some people may prefer a lighter bike with non fat tires.
