How much weight can the M-81 carry?

Addmotor rates the total payload at 400 lbs, including the rider and cargo. The integrated rear rack is the main place to strap bags or a seat.

What is the real-world range?

Addmotor claims up to 105 miles in the lowest pedal-assist level with the 48V 20Ah battery. Expect far less at higher assist or on throttle, especially with a heavy load.

Is it legal as a Class 2 e-bike?

Top speed is limited to 20 mph, which fits the Class 2 definition used in most US states. Check your local rules for cargo bikes and passenger seats.

Can I carry a child on the back?

The rear rack and 400 lb payload support a child seat or cushion accessory. Addmotor sells compatible passenger setups, and a shop should confirm the fit.

How does it compare with a standard commuter e-bike?

It is heavier and slower-handling than a commuter, but it hauls far more and rides more stably under load thanks to the fat tires and long frame.

Does it come assembled?

It ships mostly assembled, with handlebars, pedals and front wheel to fit. A local bike shop can check brakes and torque if you are not comfortable doing it.
