Addmotor Grandtan M-340 Trike


Established in 2019, Addmotor has established itself as a pioneer in the electric personal mobility industry. The brand has introduced a diverse lineup of electric bikes and electric trikes, designed to cater to riders of all ages and skill levels. While Addmotor’s products are known for their power and style, what truly sets the brand apart is its consistent commitment to providing excellent value across its entire product range.

The M-340 upholds the brand’s high standards in terms of quality, performance, and aesthetics while maintaining competitive pricing within the electric trike market.

Performance Review

The Addmotor Grandtan M-340 fat tire electric trike comes equipped with a robust 750W Bafang motor in the front wheel, powered by a substantial 48-volt Samsung battery. The trike can deliver a peak power output of up to 1000 watts… and offers three distinct riding modes: a manpower mode, motor-assisted pedaling, or full electric throttle control. Within pedal assistance, you can choose from seven different levels to fine-tune the amount of additional power you want while pedaling, enhancing the overall ease and efficiency of your ride.

The Bafang hub motor is impressively potent and delivers an impressive 80 Newton meters of torque. However, since this motor is situated in the front wheel, occasional wheel slippage may occur, especially when tackling steep inclines on loose terrain. It’s important to note that this phenomenon is common in electric bikes and trikes using a front hub motor. During our testing, we did observe this happening, but the slippage was not overly pronounced.

While conducting my test ride of the Addmotor Grandtan M-340 electric trike on smooth, well-maintained roads, it displayed remarkable acceleration, courtesy of its powerful 750W Bafang motor capable of peaking at 1000W output. I could hit a top speed of 19 mph in just about 13 seconds. After reaching this speed, the trike maintained a steady pace for the entire ride.

Top Speed

The Addmotor Grandtan M-340 has Class 2 compliance, enabling it to achieve a maximum speed of approximately 20mph (well, 19mph actually). This speed is well-suited for a variety of riding situations. However, it’s worth noting that during sharp turns at higher speeds, the electric trike may exhibit a slight lean to one side – a characteristic commonly observed in all three-wheelers.

Hill Climb

During my test ride of the Addmotor Grandtan M-340 on hilly terrain, I was genuinely amazed. It effortlessly conquered the majority of hills I encountered, all thanks to the impressive 80 Nm of torque produced by the 750W motor. However, when the incline became steeper, typically around 20 degrees, I did find it necessary to pedal a bit to provide some assistance to the trike. The RAEV Bullet GT still retains the title of the ultimate hill conqueror. I mean I still have seen nothing like it.

Ride Quality

The Addmotor Grandtan M-340 electric trike places a premium on your riding comfort above all else. It features a well-padded seat with a supportive backrest, ensuring exceptional comfort during your journeys. You not only have the flexibility to adjust the seat height and customize the handlebar position to achieve the most ergonomic riding posture, but you also can height-adjust the backrest, depending on your preference. 

Additionally, the M-340 is equipped with three 4-inch wide fat tires along with a front suspension that effectively smooths out rough roads. The trike is fairly agile with a short turning radius, but it’s worth noting that during sharp turns or corners at high speeds, you may observe some leaning behavior. Again, as I mentioned earlier, this is common for all trikes and shouldn’t come as a surprise if you have experience riding one.


The Addmotor Grandtan M-340 comes equipped with a 48V 20Ah Samsung battery, promising a maximum claimed range of 85 miles when utilizing the lowest pedal assist setting. It’s important to note that this range can vary based on total weight, level of incline, wind conditions, and other variables. During my testing on flat terrain and without any cargo, I was able to cover a distance of approximately 25.5 miles while using the highest level of pedal-assist.

If you’re in search of an electric vehicle with an exceptionally extensive range, you might want to consider the Aniioki A8 Pro Max, which boasts an enormous 48V 60Ah battery (equivalent to 2,880Wh)… or you can also explore the Bandit X-Trail Pro as another excellent option!


The Grandtan M-340 is equipped with Tektro mechanical disc brakes, with 3 x 180 mm rotors on both the front and rear wheels. Despite having a total of three discs, the braking performance leaves something to be desired, mainly because of the trike’s massive 118 lbs weight. Hydraulic brakes could have been a superior option. Nonetheless, the positive aspect is that the brakes feature motor inhibitor levers that promptly disengage the motor power when brakes are activated.


The Grandtan M-340 comes equipped with an 80mm travel oil spring front suspension fork. It is also equipped with three 4-inch wide fat tires to absorb various surface imperfections, guaranteeing a comfortable ride on both pavement and light trails. But it’s worth noting that trikes can exhibit some instability on steep hills, so it’s advisable to use them on city roads. If you’re seeking a trike with suspension both in the front and rear, Addmotor also exclusively offers the impressive full suspension SOLETRI M-366X trike.


The Addmotor Grandtan M-340 is equipped with a Shimano Tourney 7-speed chain transmission, delivering seamless gear shifts. In its lowest gear, the trike demonstrates ample power for conquering steep inclines. However, being a trike, the derailleur is positioned beneath the frame and hangs relatively close to the ground, unlike e-bikes. This necessitates extra caution when riding on trails, as the derailleur may be more vulnerable to impacts.

Addmotor Grandtan M-340 Features


In terms of pricing, the Addmotor Grandtan M-340 is a standout choice among electric trikes.

Furthermore, you’ll find all the controls thoughtfully arranged on the handlebar for ergonomic accessibility.


In true American style, the Grandtan M-340 boasts a trio of 4-inch wide fat tires. The front tire measures 24 inches in diameter, while the two rear tires are 20 inches in diameter. These high-quality tires, sourced from Kenda GIGAS, feature knobby tread patterns and a durable construction to conquer various terrains with ease. They excel at providing excellent traction on surfaces like sand, snow, and mud. Furthermore, these tires enhance your ride comfort by effectively absorbing bumps on the road or trails and minimizing vibrations transmitted to you. You also have three full length metal fenders for protection against mud and splashes.


The Addmotor Grandtan M-340 electric trike comes equipped with a front LED light to illuminate your path in low-light conditions. Furthermore, there is a rear light that not only enhances your visibility to others on the road but also includes turn signals. To enhance safety even further, the trike is equipped with pedal and wheel reflectors to increase visibility


The Grandtan M-340 features a spacious front basket and an even larger rear rack. The rear rack impressively accommodates a weight of up to 100 pounds, while the trike itself is rated for 450 lbs. It’s not only robust enough to transport such heavy loads but also boasts excellent range without running out of power. You also get a 20.5″ x 16″ x 9.5″ waterproof rear storage bag with 40-liter storage capacity, ensuring you can transport your gear with complete peace of mind, regardless of the weather conditions.

It not only delivers outstanding performance but also offers a diverse range of features that position it as a top contender within its category. Its standout features include the large Samsung battery, the convenient wooden footrest, and the rear waterproof storage bag.

On the flip side, it would have been ideal if Addmotor had opted for hydraulic brakes and cut down some of the weight. However, despite these minor drawbacks, the Grandtan M-340 remains a standout option in the electric trike market. The best thing is, the trike offers a comprehensive package comprising fenders, lights, and numerous convenient features. With that, I conclude this review.
