Addmotor stopped making front-mounted motor e-trikes due to performance and handling issues. Rear-mounted motor trikes offer better traction, stability, handling, and performance. They also provide quieter rides, reduced overheating, and more cargo capacity, making them a more efficient and reliable choice.

Compared to Grandtan standard with 24" F/20" R tires, the Grandtan Plus features 26" F/24" R tires. The 2" bigger tires make the Plus e-trike more suitable for taller people.

I purchased this M340 trike for my winter home in Key West. I also have 2 exact trikes in NH that my wife and I enjoy. The riding is completely different between flat riding in Key West and mountains in NH. I put 1600 miles on my M340 last year in NH and over 1600 miles in Key West.

These trikes are well built and I plan on purchasing another M340 next winter for my wife.

    Hi Robert,  Thank you for your great review! We're glad to hear that you love the M340 and that it performs well in both flat and mountainous terrains. Enjoy your future rides, and we look forward to your next purchase!  Best regards, Addmotor

My M340 eTrike arrived on time and was packed very well. Assembly was easy with no problems and basic operation was easy to understand. I was surprised by the trike's ability as far as speed and power are concerned. It has all the speed and power I want or need. The battery life was also a surprise as it held up as advertised. I took the trike out for several trips ranging from 5 to 9 miles each, and the battery shows that it still has around 3/4 full charge. The one area that I would change if I were to order another trike would be to purchase a model with a full rear suspension that would allow the rear wheels to compensate for uneven ground when riding on dirt paths or crowned road surfaces. I believe that a full suspension would provide a smoother and safer ride on rough terrain. The M340 Trike is well built as delivered however I will look for a softer seat.

After two years of researching electric trikes, I decided on Addmotor Grandtan M340.  I am a 73-year-old widow that due to medical problems I had to give up riding my cruiser 10 years ago on the nature trails close to my house.  I ordered two M340's in February 2025 so that my daughter could join me riding.
Shipping was fast and I received both with no damage to the bikes due to the excellent packing.  It has taken awhile to get to be able to start riding as I had to wait until I could get someone to finish the assembly of the eTrikes and then I had to wait on the weather to get nicer and the snow to melt.  Happily spring has finally arrived !  
I am very pleased with my purchase of the Grandtan M340.  I am thrilled to once again be able to ride the nature trails thanks to the stability of the eTrike and the ability to choose pedal, pedal assist or 100% electric when needed.  The M340 is a well built bike, has a great battery, and comes with a thorough assembly and operation manuel.  My new Grandtan M340 has been admired by many on the trail.
I highly recommend Addmotor to anyone looking for an eTrike that will be usable for many years.  I am looking forward to many years of rides on the trails once again and being able to enjoy the outdoors!!
  • By Man***
    Dear Nina ,  Thank you so much for your wonderful review and for sharing your experience with the Addmotor Grandtan M340. We are thrilled to hear that you are enjoying your new eTrike and that it has allowed you to get back to riding the nature trails you love.  We appreciate your kind words about the build quality, battery performance, and the comprehensive assembly and operation manual. It's heartwarming to know that your new Grandtan M340 has been admired by many on the trail.  We highly value your recommendation and look forward to helping more people discover the joy of riding an eTrike. We hope you continue to enjoy many more years of outdoor adventures on your Grandtan M340.  Thank you again for choosing Addmotor and for sharing your positive experience with others.  Best regards, Addmotor Customer Service Team

Initially I bought the 2023 Grandtan M-340 and was so impressed with the performance and ease of operation that my wife saw I was out riding 25-35 miles per day, so she ordered one for herself. Diane is not the maniac that I am, however she puts in 5-15 miles a day the weather is good here in Colorado.
I am retired, and 73 years old and Diane is 72. We love the comfort, safety, and power that Addmotor brings to the table.
We have been following the improvements made to the new Addmotor trike line and we will be buying a couple of  new trikes from Addmotor, on what is one hell of a solid trike this Spring of 2025.
Great service and great product.
We are loving it.
  • By Man***
    Hi Michael ,  Thank you so much for the amazing review! We’re thrilled to hear that both you and Diane are enjoying your Grandtan M-340 trikes so much.   We’re honored that Addmotor has been a part of your daily routine, and we’re glad to hear that you’re both finding comfort, safety, and power in our trikes. Your enthusiasm means a lot to us, and we can’t wait for you to experience the next generation of our trikes this spring.  If you ever need anything or have questions about the upcoming models, feel free to reach out. We're here to help!  Best regards, Addmotor
