The Ecotric Vortexis a fast and powerful electric bike that we feel is best suited for commuting and city riding. This bike's 350W rear hub motor packs and punch with quick acceleration, a top throttle speed of 20 mph, and the highest average speed during our distance range test. The three levels of pedal assist provide a good range of support to boost your pedaling efforts. Its 26-inch wheels and smooth city tires are fast-rolling, and this bike has consistent and steady handling. It also comes with front and rear fenders, ergonomic grips, and an adjustable stem to enhance rider comfort. The user interface is relatively basic, but it is straightforward and functional. We also found it to feel a bit on the small side, and taller riders may not find the range of seat height adjustment to be adequate. Otherwise, there was little we didn't like about this zippy electric bike.
