G20 PRO vs G10
The two Ultralite chairs share the same overall layout: 6.5" front and 11" rear wheels, an 18" seat width, a 28" turning radius and a 300 lb rating. The G20 PRO is slightly lighter (25 lb vs 25.8 lb without battery), folds narrower (10" vs 12" wide), and lists a larger 300Wh battery with up to 12 miles of range, versus 10 miles for the G10. The G20 PRO also lists a 4.5 mph top speed and 12° climbing, against 4 mph and 10° for the G10.
Carbon F1: a flatter fold
The Carbon F1 folds to a low, flat 28" × 24" × 13" package rather than the tall, narrow shape of the Ultralite chairs. Measure your trunk or storage space against both folded shapes. The Carbon F1 lists the tightest turning radius in this group at 24".
ARK: heavy-duty and all-terrain
The ARK weighs 90 lb and is built around dual 300W brushless motors, a 24V 16Ah battery and pneumatic tires (9" front, 12.5" rear). It lists the longest range in this group, up to 15 miles, and the highest capacity at 330 lb. Plan how you will load and transport a 90 lb chair before you order.
