The Addmotor GAROOTAN M-81 is a step-through cargo e-bike designed for riders who want electric assistance along with useful carrying capacity for groceries, gear, commuting, and everyday trips. Addmotor currently lists a 750W rear motor, 48V 15Ah Samsung battery, up to 75 miles of claimed range under PAS 1 conditions, a 400-pound maximum payload, and a 20 mph top speed.

*Addmotor’s current product page lists the 15Ah battery and 75-mile range, while some Addmotor/CJ materials list a 20Ah configuration. Specifications should be confirmed at the time of purchase.
Then add this paragraph:
The M-81 is built around utility rather than just recreation. Its step-through frame makes mounting and dismounting easier, while the integrated cargo area and 400-pound maximum payload give it more carrying flexibility than a typical commuter e-bike. The 750W rear motor also provides substantially more assistance than a low-powered city bike.
Motor and Riding Performance
The GAROOTAN M-81 uses a 750W rear brushless motor, giving it enough assistance for everyday commuting, cargo hauling, and general utility riding. Addmotor currently lists the bike with a 20 mph top speed, which places it in a practical range for neighborhood trips, bike paths where permitted, and everyday transportation.
Because this is a cargo-oriented e-bike, the motor is doing more than simply helping the rider maintain speed. It also has to help move the bike when carrying groceries, gear, or other loads. That makes the 750W motor a useful match for the M-81’s 400-pound maximum payload rating.
The M-81 is better viewed as a utility-focused e-bike than a performance bike. Its strengths are carrying capacity, practical assistance, and ease of use rather than high-speed riding.
Battery and Claimed Range
Addmotor’s current M-81 product page lists a 48V 15Ah Samsung battery and a claimed range of up to 75 miles per charge in PAS 1 conditions. Those numbers are useful as a reference point, but actual range will vary with rider weight, cargo load, terrain, wind, temperature, tire pressure, assist level, and riding speed.
Because the M-81 is designed as a cargo e-bike, carrying heavier loads can reduce range more noticeably than on a lightly loaded commuter bike. Riders using the bike for groceries, gear, or other cargo should expect real-world range to be lower than the maximum advertised figure in many situations.
One thing to note is that Addmotor’s CJ product feed currently labels the M-81 as a 20Ah model, while the live Addmotor product page lists 15Ah. For that reason, we recommend confirming the battery size shown on the current product listing before purchase.
Step-Through Frame and Everyday Utility
The GAROOTAN M-81 uses a step-through frame, which can make getting on and off the bike easier than with a traditional high top-tube design. That can be especially helpful when the bike is carrying groceries, gear, or other cargo and the rider wants to avoid swinging a leg high over the rear of the bike. Addmotor positions the M-81 as a compact cargo e-bike for commuting, errands, and everyday utility.
Its compact cargo-bike layout also gives riders more carrying capability without moving into a much longer longtail-style bike. The combination of a step-through frame, fat tires, and integrated rear cargo area is intended to make the M-81 practical for regular transportation as well as recreational riding.
Cargo Capacity and Rear Rack
The GAROOTAN M-81 is built with utility in mind, and Addmotor currently lists a 400-pound maximum payload capacity. That gives the bike more flexibility for carrying groceries, bags, work gear, or other everyday cargo than a typical recreational e-bike.
The extended rear section is one of the M-81’s defining features. It gives riders a larger platform for cargo setups, although accessories such as passenger cushions, baskets, or enclosures may be sold separately rather than included with the bike. Addmotor’s own product Q&A indicates that some rear-seat and cargo accessories are not standard equipment, so buyers should check the current product listing for what is included.
For someone who wants an e-bike for errands, groceries, or hauling gear, this cargo-oriented design is one of the M-81’s biggest advantages over a standard commuter bike.
Fat Tires, Comfort and Stability
The GAROOTAN M-81 uses 20 × 4-inch fat tires, which are designed to provide extra traction and cushioning compared with narrower city-bike tires. That can help on pavement, gravel, and other uneven surfaces, especially when the bike is carrying additional weight. Addmotor describes the wider tires as helping with shock absorption and stability across mixed terrain.
For a cargo-oriented e-bike, that added stability can be useful when starting, stopping, or riding with groceries and gear on the rear section. The wider tire footprint can also make the bike feel more planted at lower speeds, though fat tires generally create more rolling resistance than narrow commuter-bike tires.
Addmotor also lists hydraulic disc brakes for the M-81, which are a good match for a heavier utility bike because they provide stronger and more consistent braking than basic mechanical systems.
Brakes, Gearing and Controls
The GAROOTAN M-81 uses hydraulic disc brakes, which are well suited to a heavier cargo e-bike because they provide strong, consistent stopping power with less hand effort than basic mechanical brakes. Addmotor has also listed 180 mm brake rotors on the M-81, giving the bike more braking surface for slowing a loaded bike.
For pedaling, Addmotor has described the M-81 with a 7-speed Shimano drivetrain and multiple pedal-assist levels. That gives riders a choice of mechanical gears along with electric assistance, which can be helpful when starting from a stop, climbing hills, or carrying cargo.
The bike also includes a handlebar display for monitoring riding information and supports throttle operation in addition to pedal assist. Addmotor has described the M-81 with a half-twist throttle and a multifunction LCD on prior/current M-81 materials.
Who Is the Addmotor GAROOTAN M-81 Best For?
The GAROOTAN M-81 is best suited to riders who want an e-bike that can handle everyday transportation and cargo without moving into a much larger longtail design. Addmotor positions it as a compact cargo e-bike with a step-through frame, fat tires, a 750W rear motor, and a 400-pound payload rating.
It may be a good fit for:
- Commuters who want electric assistance plus room for work bags or groceries.
- Errand riders who want more carrying capacity than a standard city e-bike.
- Families who may want to add compatible cargo or passenger accessories.
- Riders who prefer a step-through frame for easier mounting and dismounting.
- People with limited storage space who want a cargo bike that is more compact than a full-length longtail model.
- Riders who regularly carry gear and want a higher payload rating than a typical recreational e-bike.
The M-81 may be less suitable for someone who wants a lightweight e-bike for carrying upstairs, a high-speed performance bike, or a very long cargo platform for heavier commercial hauling.
Pros and Cons of the Addmotor GAROOTAN M-81
Pros
- 750W rear motor gives it useful power for commuting, errands, and carrying cargo.

Cons
- At about 85 pounds in Addmotor’s published M-81 materials, it is much heavier than a standard bicycle and may be difficult to carry upstairs or load without help.
- Fat tires and a cargo-oriented frame can make the bike feel bulkier than a lightweight commuter e-bike.
- Addmotor’s current live product page lists a 48V 15Ah battery with up to 75 miles of PAS 1 range, while some Addmotor/CJ materials list a 20Ah battery and higher range, so buyers should verify the exact configuration before ordering.

Is the Addmotor GAROOTAN M-81 Worth Considering?
For riders who want a practical cargo e-bike without the length and bulk of a full-size longtail model, the GAROOTAN M-81 is worth considering. Its 750W rear motor, 400-pound payload capacity, step-through frame, 20 × 4-inch fat tires, and hydraulic disc brakes give it a useful mix of utility and everyday rideability.
The strongest reason to consider the M-81 is versatility. It can serve as a commuter, grocery hauler, gear carrier, or general-purpose utility bike while still remaining more compact than many larger cargo models.
The main point to double-check before buying is the battery configuration. Addmotor’s current live product page lists a 48V 15Ah Samsung battery and up to 75 miles of PAS 1 range, while some Addmotor promotional materials and the CJ feed reference a 20Ah battery and higher claimed range. We recommend confirming the exact battery and range shown on the current product listing at the time of purchase.
