The Greattan D from Addmotor brings an aggressive approach to electric cargo trikes, combining oversized 7-inch rear fat tires, a 750W motor with 1,400W peak output, and a heavy-duty axle designed for serious hauling across unpredictable terrain.
Fat tires are a staple of Addmotor’s all-terrain lineup, but this model takes things further. Up front is a 4-inch tire, while both rear wheels sit on aluminum rims wrapped in extra-wide 7-inch rubber. The trike is built to maintain grip and balance whether the surface is pavement, loose dirt, or rocky trail. Supporting it all is a rear axle that’s been reinforced and thickened by 20%, aimed at preventing flex when carrying larger payloads.
The Greattan D is rated to handle up to 500 lb (227 kg) in total, with the rear cargo platform alone supporting up to 150 lb (68 kg). The rear rack spans nearly the full width of the trike, making it suitable for larger gear, deliveries, or worksite tools.
Power comes from a rear-mounted motor supported by a torque sensor, with assist levels adjustable through seven modes. Riders can also engage a half-twist throttle to move without pedaling. The motor tops out at 20 mph (32 km/h).
The system includes a downtube-mounted UL-certified battery, and an additional seat-tube-mounted pack can be added to expand capacity. No estimated range is currently provided.
Designed for control under load, the Greattan D includes a speed differential, front suspension, and a cushioned seat with integrated backrest. Riders also benefit from a Shimano 7-speed transmission, mechanical disc brakes, a manual parking brake, and built-in lighting for visibility, including turn indicators.
Addmotor lists the Greattan D at $4,399 MSRP, with a pre-order price of $3,799 for the single-battery version. The second battery can be added for $699, bringing the total to $4,498.
Etrikeco’s Take on the Greattan D
Addmotor has packed the Greattan D with features that push it beyond the limits of most cargo e-trikes.
From the oversized tires and stiffened rear axle, to its expanded cargo capacity and torque-sensing drive, this model is built for riders who need more than just basic transport. It’s positioned for those hauling gear across mixed terrain, not just asphalt.
Where many cargo trikes top out in stability once weight increases, the Greattan D responds with structural reinforcements and traction-first design. Add in the option for dual batteries, and it’s ready to go farther — even if exact range details remain unclear.
Rather than aiming for sleek or minimalist, this trike leans hard into practicality. It’s not trying to blend in — it’s made to handle jobs that demand more.
