A full-size, pedal-equipped electric dirt bike with two 48V batteries, 19-inch motocross-style wheels and a claimed 85 miles on throttle alone.
This is the bike to look at if the GT54 feels too small. It is a bigger frame with 19-inch dirt bike tires, two removable 48V 18.2Ah batteries and a 330 lb load rating, and it keeps pedals and a cadence sensor. The headline range of 85 miles on throttle and 155 miles with pedal assist is a manufacturer figure that depends heavily on speed and rider weight, and the page says so. At $1,349 it sits in the middle of the Riding'times range.
The GT73 is 73.82 inches long and 45.91 inches tall, rides on 25 x 3 inch off-road tires (70/100-19) and uses 7074 aluminum alloy rims. The product page shares one spec table with the GT73 Pro, so check the left-hand GT73 column.
The GT73 column lists a 2400W rear gear hub motor, 126 N·m of torque and a speed of 28 to 37 MPH depending on road condition and load. A 48V 30A integrated controller manages it.
Two removable UL 2849-compliant batteries with two 54.6V 2A chargers. Charging takes 9 to 10 hours, which is slow, but you can swap or charge packs separately.
Dual hydraulic disc brakes with 230 mm rotors plus EABS, front and rear LED lights, turn signals and a combined brake and turn signal light. The throttle is full-twist and there is a cadence sensor for pedal assist.
An aluminum front fork with adjustable damping and a 1200-LB S rear shock. The bike is rated IPX4 for water resistance, so splashes are fine but it is not a submersible.

The GT73 trades some power for load rating, range and price. For most adult riders on private land or permitted trails it is the more sensible of the two GT73 models.
