Electric trikes have come a long way in terms of stability, comfort, and power, but Addmotor’s latest release adds something extra: company. The M-380 Tandem Electric Trike is a dual-rider e-trike designed for smooth, flexible two-person cruising across city streets, park trails, or even light off-road paths.
While tandem bikes have traditionally been tricky to ride and balance, the M-380 tackles this by combining a low step-through frame with fat tires, suspension, and a powerful 750W motor—all wrapped in a platform stable enough for two full-sized adults. Whether it’s for couples, touring partners, or simply friends who prefer to ride together, this is one of the most capable tandem electric trikes currently available.
Power for Two, Without the Tug-of-War
The M-380 is powered by a 750W rear hub motor paired with a 48V 20Ah Samsung battery. In pedal assist mode 1 (PAS1), it’s rated for up to 60 miles on a single charge. In typical usage—especially when climbing hills, using higher PAS levels, or throttle-only mode—you can expect a real-world range of 30 to 40 miles. Riders seeking longer range can purchase an optional second battery, which expands total capacity and could double your range depending on usage conditions.
With a top speed of 20 mph (Class 2 compliant), the trike performs reliably across flat terrain and moderate inclines, even when fully loaded.
Ride Together, Pedal Independently
One standout feature of the M-380 is its flexible two-person pedaling system. Unlike traditional tandem bikes where both riders must pedal in sync, the M-380 allows the front and rear riders to pedal at different speeds—or even stop pedaling entirely. This is ideal for riders with different fitness levels, or for those who want to take turns powering the ride. When needed, you can simply switch to throttle mode and cruise without pedaling at all.
To support this, the rear rider is given a stylish wooden footrest, allowing them to relax during long stretches or while riding throttle-only.
Stable, Comfortable, and Built to Share
Built on a rugged step-through frame, the M-380 is designed for ease of use. Both riders benefit from upright seating, with the rear seat offering an extra-wide saddle, full backrest, and foot support. The front seat is adjustable, and the handlebars are set to a relaxed, ergonomic position for confident steering.
Fat 4-inch-wide tires offer enhanced grip and cushioning, while a front fork with 80mm of suspension travel helps absorb road shock. Whether you’re rolling over cracked pavement or transitioning onto gravel paths, the ride remains smooth and composed.
Tektro mechanical disc brakes on all three wheels provide strong stopping power, even when the trike is loaded to its 500 lb maximum capacity (350 lb rider + 150 lb passenger/cargo). This ensures consistent braking performance on city streets, bike trails, and even wet surfaces.
Ready for Real-World Utility
The M-380 comes standard with integrated front and rear lights, a rear cargo rack, and full fenders. The frame is designed to support Addmotor’s trailer hitch, giving you options for even more storage or additional passengers (such as child trailers or pet carriers). While the trike’s weight hasn’t been officially published, its large frame and three-wheel configuration suggest it will require a ramp or trailer for long-distance transport.
As with many cargo-focused trikes, portability takes a back seat to power and comfort—but for riders who value stability and long-haul practicality, the tradeoff is worth it.
Final Thoughts
The Addmotor M-380 Tandem Electric Trike is a thoughtfully engineered platform for two. It solves many of the coordination issues common with traditional tandem bikes by allowing independent pedaling, full throttle override, and a more upright, relaxed riding posture for both riders. Whether you’re an older couple looking for a fun way to stay active, or two friends seeking weekend adventures, the flexibility this trike offers is a standout feature.
One key strength of the M-380 is its rear-wheel drive system paired with fat tires and front suspension—a trio that provides better traction, ride comfort, and stability than most standard tandem bikes or scooters. The inclusion of mechanical disc brakes on all three wheels also adds to its safety profile, especially when carrying heavy loads or descending mild slopes.
The independent pedaling system is especially interesting. While it avoids the classic “both must pedal” limitation of sync-gear tandems, it introduces complexity in coordination. On the one hand, it allows riders with different energy levels or physical abilities to ride together. On the other, it might require a little practice to find a rhythm when both riders are actively contributing.
With a combined weight rating of 500 lbs, the M-380 handles two adult riders comfortably, but it’s worth noting that hill-climbing ability may still be impacted by rider weight and incline steepness. The 750W motor provides solid output, but in throttle-only mode, steeper hills may require supplemental pedaling—especially under full load. That said, the inclusion of a 7-speed gear system gives riders extra control when dealing with varied terrain.
Range is another consideration. While Addmotor lists up to 60 miles on a full charge with PAS1, real-world riding with two people and mixed terrain will likely bring that closer to 30–40 miles, particularly if using throttle frequently. Fortunately, the option to add a second battery makes this trike better suited for longer-range touring.
And here’s the real catch: this trike sells for $3,999—and that’s just the base, single-battery version. With a large frame, wide stance, and estimated weight exceeding 100 lbs, transporting the M-380 will likely require a ramp or trailer.
So here’s the bottom line: if you truly plan to ride tandem—frequently, with purpose—and have the storage space and budget to match, the M-380 is one of the few e-trikes that can do the job right. But if you’re buying it “just in case” or don’t regularly ride with a partner, you’re better off with a lighter, cheaper, solo-focused model. This is a capable machine—but it’s not for casual riders.
