I put 1500 miles on a Sondors Fat, then wanted a different kind of ride. I bought a Haibike XDURO Full Seven S RX. It is a class 3 bike, 28mph, but no throttle. The Bosch mid drive will actually pull the suspension forks up in Turbo mode, so don't need a throttle as long as you can just move your legs. Large dia. rotors and hydraulic brakes to haul you quickly to a stop from 28mph. Then I bought a second bike, a Haibike XDURO Trekking S RX. Same Bosch mid drive, 28mph. But it has a 500whr battery instead of the 400 on the mtb. It also has smaller gravel type tires, full fenders, a rear rack, and 10 speeds vs 11. I've now put on 2500 miles on the two Haibikes, the Sondors collects dust in the corner until snow flies in the winter. I'm crazy about the quality and precision of Haibike and Bosch.
