KAKIGO Two-Seater Electric Trike

The 30-second verdict

Two-seat electric trikes barely exist. Most "passenger" e-bikes are a long-tail cargo bike with a rear pad, which works for a child and is uncomfortable and slightly alarming for an adult. KAKIGO builds an actual bench: a wide two-person seat with safety belts, rated to 330 lbs combined, on a folding aluminium-rimmed trike with a rear differential, 20" x 4" fat tyres, 7-speed gearing and anti-tip wheels included in the box. The battery is a 48V 15.6Ah (748.8Wh) pack the listing states is UL 2849-certified — the standard fire codes actually name, and a genuine tick at this price. The top speed is given as 20 mph and torque as 90 Nm, which is the most torque on our trike shelf and the right specification for moving two adults from a standstill. What KAKIGO never publishes is a rated wattage, and that omission has legal consequences we work through below.

The wattage gap is the problem, and it is not pedantry

The listing quotes 1,350W peak and stops there. Peak wattage is a brief output figure; it is not what any statute regulates. The federal definition at 15 U.S.C. § 2085 and the three-class framework 49 states copied from it are written in terms of rated continuous wattage, with a 750W ceiling — Oregon alone allows 1,000W. A machine advertising 1,350W peak might have a 500W rated motor, a 750W one, or a 1,000W one; all three are plausible engineering choices behind that number, and only two of them are legal e-bikes in most of the country. This is why we have left the class field empty rather than guessing: a guess here would be the difference between a bicycle and an unregistered motor vehicle. Before buying, ask KAKIGO for the rated continuous wattage in writing, and check it against your state's rules. If the answer is 750W or below, this is a Class 2 machine and rides anywhere a bicycle does.

Carrying a passenger is its own legal question

Even with the wattage settled, a second rider raises a separate issue that two-wheel buyers never meet. Many state vehicle codes permit a passenger on a bicycle only where the bicycle is equipped for one — a designed seat, not a rack or a crossbar. That is a rule this machine passes comfortably and most e-bikes fail: the bench is a designed, belted, load-rated seat, which is exactly the equipment those statutes describe. A handful of states also set a minimum age for a passenger or require a helmet for one regardless of the rider's age, and those rules sit in the same statutes as the class definitions. The practical guidance is simple: this is one of the few e-bikes that can carry an adult passenger lawfully in most places, but check the passenger rule in your state alongside the class rule, because they are separate provisions and the second one catches people out.

Range: the claim is not close

KAKIGO claims 80-90 miles per charge in pedal-assist mode. The pack is 48V x 15.6Ah = 748.8Wh. Eighty miles from 748.8Wh requires 9.4 Wh per mile. A single rider on an efficient road e-bike might approach 12-15 Wh per mile; a fat-tyred trike carrying two adults draws something closer to 28-35 Wh per mile, because you are moving perhaps 330 lbs of people plus a heavy machine on three high-resistance tyres. The realistic number is 749 ÷ 30 ≈ 25 miles with two aboard, and perhaps 35 solo. That is still a genuinely useful range for the trips this machine is for — a park, a promenade, a campsite loop, a ride to lunch — but it is a third of the advertised figure, and anyone planning around 80 miles will be walking.

What the 90 Nm and the differential are actually for

Torque matters more than top speed here. Getting 330 lbs of riders rolling from a standstill on a slight rise is the hardest thing this machine does, and 90 Nm is the highest figure on our trike shelf — comfortably above the NARRAK 750 and the Jasion, neither of which publishes torque at all. The rear differential matters more again with two aboard: a trike with one driven wheel scrubs through corners, and adding a passenger doubles the mass fighting that. The anti-tip wheels supplied in the box are an honest inclusion for a tall, heavily loaded three-wheeler, and their presence tells you something about how the machine behaves when the bench is full and the corner is tighter than expected.

The delivery caveat, in KAKIGO's own words

The first bullet on the listing is a warning that the trike ships in two separate packages — the machine in one, and the charger, rear-view mirrors and anti-tip wheels in the other — and that they may arrive on different days. That means a delivered trike may sit unusable until the second box turns up, since the charger is in it. It is a genuine planning issue rather than a defect, and KAKIGO deserves some credit for leading with it rather than burying it, but do not order this expecting to ride on delivery day.

Who should buy it

Couples who want to ride together on one machine, riders with a partner who cannot cycle independently, and anyone whose use case is a passenger rather than cargo. Skip it if you need the rated wattage settled before you buy and cannot wait for an answer, if you were planning on the advertised range, or if a single-seat trike like the NARRAK 750 would do the job for $500 less.
