This is the 17/14 version of MotoTec's 72v 8000w Pro, the wheel package built around a 17 inch front and 14 inch rear. The smaller rear wheel shortens the gearing and pulls the whole bike down a little: the seat sits at 31.5 inches with 11.4 inches of ground clearance, which makes it the easier of the two 8000w bikes to get a foot down on and the better fit for riders at the shorter end of the range. MotoTec rates this one for riders 16 and up.

Power comes from a 72 volt 8000 watt motor fed by a 72 volt 35 amp-hour lithium battery, with an IP65 water rating on the system so wet trails and puddles are not a problem. Three speed modes are selected from a handlebar switch at 28, 40 and 50 mph, and the 50 mph ceiling is the practical difference between this bike and its 19/16 sibling. Expect 40 to 60 minutes of riding per charge, with a 5 to 6 hour recharge from empty.

The chassis is set up for hard use. Hydraulic disc brakes work at both wheels, two hydraulic front shocks pair with a damped rear shock, and 70/100-17 front and 90/100-14 rear knobby pneumatic tires put the power down on loose ground. A half twist variable throttle meters the delivery, and the display reports battery level, speed, which of the three gears is selected and total miles. The bike measures 72.5 x 31.5 x 44.5 inches on a 48.8 inch wheelbase and weighs 165 lbs.

17/14 vs 19/16 Wheel Package

  • 17 inch front and 14 inch rear wheels, versus 19 and 16 inches on the taller model
  • Lower 31.5 inch seat height, against 33.3 inches
  • 11.4 inches of ground clearance, against 13.2 inches
  • Top speed of 50 mph in third gear, against 56 mph
  • Rated for riders 16 and up, where the 19/16 is rated 18 and up
  • Slightly lighter at 165 lbs, against 169 lbs
