Addmotor Soletri II M-366X Etrike
The Addmotor Soletri II M-366X is a full-suspension electric trike built around an extra-long banana saddle that seats two adults.
A 48V 750W rear-mounted motor and a 48V 20Ah Samsung UL-certified battery deliver up to 85 miles per charge at pedal-assist level 1, and a torque sensor across 7 assist levels matches the power to your own effort. Addmotor rates it for a 350 lb rider plus 100 lbs of cargo.
The 17-inch step-through frame is built for easy mounting, paired with an ADDSHOX dual-crown oil-spring fork with 80mm of travel, Tektro Aries mechanical disc brakes on 180mm rotors with motor cutoff, a parking brake for holding it on a slope, and a rear differential so the back wheels turn at different speeds through a corner.
Kenda GIGAS puncture-resistant 20 x 4.0 fat tires, a 7-speed Shimano Altus drivetrain, aluminum front and rear fenders, and EB 2.0 lighting with turn signals and a brake light. Fits riders from 5 ft 2 in to 6 ft 2 in.
