The Buzz Centris is a Class 2 folding electric bike that performs extremely well in braking, acceleration, and assisted hill climb tests, though it falters somewhat when it comes to range, unassisted cruising, and control response tests. Its battery capacity is on the lower end, too, so you shouldn’t expect the Centris to travel as far as the other electric bikes we test. Still, it’s fairly inexpensive compared to the competition.
