A family cargo trike must do much more than move one rider along a flat bike path. It may need to carry children, groceries, pets, school bags, tools, and other supplies while repeatedly starting from intersections, climbing neighborhood hills, and maintaining a predictable speed in traffic.
This is why motor power and battery range should be considered together. A strong motor without sufficient battery capacity may consume its available energy too quickly. A large battery paired with an underpowered motor may still leave the rider struggling during loaded starts or steep climbs.
The Bunch Original 4+ and Addmotor E-325 are both front-loading electric cargo trikes designed for family transportation. However, their power systems are noticeably different. Bunch uses a 500W motor producing 45Nm of torque and pairs it with a 614Wh battery. The E-325 uses a 750W rear-drive motor capable of reaching 1,400W peak output and 90Nm of torque, supported by a 960Wh Samsung battery.
Bunch offers more passenger seating, but when the comparison focuses on acceleration, hill performance, battery reserve, and the ability to complete longer daily routes, the Addmotor E-325 has a clear technical advantage.

Both trikes have a top speed of 20 mph, so the E-325’s stronger motor is not intended simply to make the vehicle faster. The additional output is more valuable during acceleration, hill climbing, and heavily loaded riding.
Why 750W Is More Appropriate for a Loaded Cargo Trike
A 500W motor can provide adequate assistance for many neighborhood journeys. That does not make the Bunch Original 4+ weak. Its drive system is designed around controlled family riding, and its 45Nm motor can handle short urban routes under suitable conditions.
However, a cargo trike becomes much more demanding as weight is added. The rider may be transporting two children in the morning and carrying groceries on the return journey. Each stop requires the motor to overcome the combined mass of the trike, rider, passengers, battery, and cargo.
The E-325’s 750W nominal rating gives it more continuous power for these situations. Its peak output of up to 1,400W provides additional short-term assistance when the trike starts from rest, approaches an incline, or needs to regain momentum after slowing down.
Peak power should not be confused with continuous output. A motor does not operate at maximum peak power throughout an entire ride. Instead, peak capacity provides a temporary reserve for the moments when demand is highest.
That reserve is particularly useful on a heavy three-wheel vehicle. Riders are less likely to feel that the motor is already operating near its limit every time the cargo box is filled.
Twice the Torque Makes a Practical Difference
Motor wattage receives the most attention, but torque may be even more important for a cargo trike. Torque describes the turning force available to help move the vehicle from a stop and continue pulling under load.
The Bunch Original 4+ is rated at 45Nm, while the E-325 delivers up to 90Nm—twice the stated torque.
This difference can be felt most clearly at low speeds. Imagine stopping at the bottom of a hill with children and groceries in the front box. The trike must begin moving before it can build useful momentum. A higher-torque system can provide stronger initial assistance and reduce the amount of force the rider must apply through the pedals.
The same advantage appears during frequent urban stops. School runs may involve intersections, traffic lights, driveway exits, pedestrian crossings, and parking-lot maneuvers. A cargo trike that restarts more confidently can feel easier and less tiring to operate.
The E-325 also uses a mid-axis torque sensor. Instead of merely detecting whether the pedals are turning, a torque sensor responds to how much pressure the rider applies. This helps the motor deliver assistance more naturally and makes the available 90Nm easier to control.
Battery Capacity Explains the Range Difference
Published range figures can vary because manufacturers may test under different conditions. Passenger weight, hills, tire pressure, wind, temperature, speed, throttle use, and pedal-assist level can all change the final result.
Battery capacity therefore provides a useful point of comparison. The Bunch Original 4+ has a 614Wh battery, while the Addmotor E-325 carries a 960Wh battery. The E-325 has approximately 56% more stored energy.
Bunch publishes an estimated range of 20–30 miles depending on terrain and load. Addmotor advertises more than 60 miles under PAS 1 conditions.
The 60-mile figure should not be interpreted as a guarantee that every rider will travel that distance while carrying maximum weight. Using higher assist levels, climbing hills, riding in cold weather, or relying heavily on the throttle will reduce range.
Nevertheless, the larger 960Wh battery gives the E-325 more energy to work with before those variables are considered. Even when both trikes are operated under demanding conditions, the Addmotor begins with a substantially larger reserve.
Long Range Is About More Than Long-Distance Trips
Many families do not plan to ride 60 miles in one day. That does not make the larger battery unnecessary.
A school round trip might cover six miles. Adding a grocery store, park, library, or afternoon activity can quickly double the distance. When those journeys are repeated over several days, a smaller battery may need to be charged much more frequently.
The E-325’s larger capacity can allow several short journeys to be combined before charging. It also provides flexibility when a planned route changes. A parent can add another stop without immediately calculating whether enough battery remains for the journey home.
Lower charging frequency may also make the trike easier to integrate into daily family life. Instead of remembering to connect the charger after almost every outing, the rider has more room to establish a convenient charging routine.
The extra capacity also acts as useful insurance as a battery ages. All lithium-ion batteries gradually lose some usable capacity over time. Starting with 960Wh provides more long-term range margin than starting with 614Wh.
Power Reserve Helps Preserve Usable Range
It may seem that a stronger motor must always produce worse range. In reality, efficiency depends on how the motor is operated.
A smaller motor working close to its limit during every hill climb and loaded start may draw substantial current and produce more heat. A larger motor with adequate torque may complete the same task without remaining under maximum stress for as long.
This does not mean the 750W E-325 will automatically use less energy than the 500W Bunch in every situation. Aggressive throttle use and high assistance will still consume the battery rapidly. The advantage is that Addmotor pairs its more powerful motor with a proportionally larger energy supply.
The 25A controller, seven pedal-assist levels, and torque sensor allow riders to choose how much assistance they need. Low assistance can preserve battery capacity on flat roads, while higher levels remain available for hills and heavy loads.
This balance is more useful than simply installing a powerful motor and a small battery. The E-325 provides both pulling strength and the energy reserve needed to support it.
Bunch Still Has an Important Passenger Advantage
Bunch should not be dismissed. The Original 4+ provides four belted passenger positions and a 600-pound total weight rating. The E-325 has two cushioned seats, two seat belts, and a 550-pound total payload rating.
A family that regularly transports three or four children may reasonably choose Bunch despite its shorter range and lower motor torque. Seating capacity is not a feature that can be replaced by stronger electrical specifications.
However, many households only need to carry one or two children. For these families, the additional Bunch seats may remain unused, while the smaller battery and more conservative motor affect every journey.
The E-325’s two-seat layout is sufficient for many daily school runs while leaving the front box useful for pets, shopping bags, packages, and other cargo.
Final Verdict
The Bunch Original 4+ is a specialized family trike with excellent passenger capacity. Its four-seat box and 600-pound payload make it attractive to larger households that prioritize maximum seating over long-distance performance.
For most families carrying one or two children, the Addmotor E-325 offers the stronger power-and-range package. Its 750W motor provides 50% more nominal output than the Bunch motor, while its 90Nm torque rating is twice as high. Its 960Wh Samsung battery also stores approximately 56% more energy than the Bunch model’s 614Wh pack.
These differences matter during loaded starts, hill climbs, multi-stop errands, and repeated weekly journeys. The E-325 does not merely advertise a larger range number. It combines stronger low-speed pulling power with enough battery capacity to make that performance useful over longer distances.
Bunch wins when four passenger seats are essential. Addmotor wins when buyers prioritize acceleration, climbing ability, fewer charging interruptions, and greater freedom to complete longer daily routes. In the Bunch Electric Cargo Bike vs. Addmotor E-325 comparison, the E-325 is the more capable choice for riders who expect their cargo trike to deliver both serious power and dependable range.
