Along with its stout chassis, long wheelbase and burly build kit, the Rail is capable of monster trucking its way down some pretty gnarly descents [...] the Bosch Performance CX Line motor is another key component to the Trek Rail’s all-round performance. In our experience, this is the best full-powered motor out there.'
