It's electric, and it's a mountain bike! A little bit too traditional of a mountain bike for our my tastes, if I'm being honest; it's rocking a 27 speed Shimano drivetrain, but the reality is that no electric bike needs to have that many gears, so it's just extra weight and complexity. The TX19 is rocking a 500 watt rear hub motor, which is undoubtedly fun to cruise around on, but again it's not a great fit for a mountain bike; most MTB trails don't allow a motor that powerful, and hub motors are just not great at climbing, which of course is something mountain bikes have to do frequently. Still, it is full suspension with hydraulic brakes, and should perform pretty well provided you can find good places to ride it.
