1. Jasion RetroVolt 330: best overall
The RetroVolt is the two-seat e-bike Amazon buyers choose most: #1 in Amazon's Electric City Bikes at our November 2026 check, and by sales rank far ahead of every other bike on this page. Its long bench has a rear seat pad the listing markets for short passenger trips, under a 330 lb payload. Behind a 180 lb rider that leaves 150 lb for the passenger and any bags, and two average adults can exceed it. Jasion's manual rates the motor at 750 W (the 2000 W in the title is the peak), the battery is 720 Wh, and Jasion's product photos show a coil rear shock as well as the front fork. Its review does not mention passenger footrests, so check the listing photos.
Legal status: legal once set. As shipped, with a throttle and 30 mph in the title, it fits no class. Jasion's manual documents two settings: P07 sets the speed limit, and a 20 mph limit meets the Class 2 speed rule; P08 = 1 switches the throttle off, so pedal assist to 28 mph matches Class 3. Do one of them before you ride on the street. Plan on 30-35 miles per charge solo, fewer with a passenger. Read the Jasion RetroVolt 330 review.
2. Kingbull Ranger: best for two adults
The Ranger is the one bike here whose review calls it designed for two adults: the bench runs the length of the top tube, footrest pegs come in the box, and Kingbull sells a rear seat cushion for it. Kingbull publishes both numbers that govern two-up riding, a 350 lb payload and a 150 lb rear rack limit, and the rack figure binds first: a 150 lb passenger is at its ceiling, so two large adults are outside the specification even when the total is under 350 lb. The 864 Wh battery is bigger than the RetroVolt's, good for 31 to 43 miles of ordinary riding by our review's arithmetic.
Legal status: legal as shipped. Kingbull rates the motor at 750 W (1300 W peak) and ships the Ranger as a Class 3 (28 mph pedal assist) with Class 2 selectable in the display; choose Class 2 in the seven jurisdictions that do not recognize Class 3. Two cautions. Kingbull's spec table names no brake type on an 88 lb bike (a second Amazon listing for it claims dual hydraulic discs), so ask the seller to confirm the brakes in writing before you carry a passenger. And it is a weak seller on Amazon, and its saddle is fixed and cannot be adjusted. Read the Kingbull Ranger review.
3. SISIGAD Family E-Bike: best for a child passenger
The SISIGAD is the only bike here that arrives ready for a small child: the rear child seat and foot guards are built in, on a reinforced deck, so there is no third-party seat to buy and no rack rails to match, and the foot guards keep small feet out of the spokes. It also has the highest payload on this page, 450 lb, which leaves 270 lb behind a 180 lb rider, along with dual hydraulic disc brakes and a UL 2849 certified system with a removable 720 Wh battery. The seat suits one child; for two, its review points to a dedicated longtail. Plan on 30-45 miles with a child aboard.
Legal status: legal as shipped. It is 750 W rated with a 28 mph Class 3 top speed and a Class 2 or Class 3 setting in the display, and its review says to keep it in Class 2 (20 mph) whenever a child is on the back. Support runs through the Amazon seller rather than a US dealer. Read the SISIGAD Family E-Bike review.
4. EUYBIKE 2-Seater: most room on a bench
The EUYBIKE is the bike its name promises: an extended fat-tire frame with a passenger bench and foot pegs, built for an older child or an adult passenger on short hops. Its build puts it in roughly the 400 lb class, which would leave about 220 lb behind a 180 lb rider, but EUYBIKE does not headline a payload figure, so confirm it with the seller before carrying a heavy passenger. It has the biggest stated battery of the two-wheel picks, 960 Wh, a 750 W rated motor (1450 W peak), and a suspension seatpost plus a front fork. Plan on 30-45 miles with two riders.
Legal status: not street legal as sold. The listing advertises 35 mph, above every e-bike class, and no speed setting is documented. Its review says to keep it limited to 28 mph on public roads, so ask the seller in writing how to set a limit before you buy it for the street. Read the EUYBIKE 2-Seater review.
5. Heybike Ranger: best street-legal pick for a child seat
The Heybike Ranger carries a child on its rack: a rear rack rated to 150 lb whose standard rail mounts take a Thule Yepp Maxi child seat (a 5 lb seat for a child up to 49 lb) with about 95 lb of cargo room to spare. Under a 400 lb payload that leaves 220 lb after a 180 lb rider. It has the paperwork the cheaper two-seaters lack, UL 2849 for the system and UL 2271 for the battery, listed on Amazon, plus hydraulic disc brakes on 180 mm rotors. It also folds, to 40 x 20 x 31 inches, and at our November 2026 check it sold better on Amazon than every pick here except the RetroVolt. The seat is not included, it suits one child, and its 600 Wh battery is the smallest stated among the picks, about 25-35 miles at mid assist by our estimate.
Legal status: legal as shipped. 750 W rated (1400 W peak), shipped as Class 2 (20 mph), with Class 1 and Class 3 (28 mph pedal assist) in the display. Read the Heybike Ranger review.
6. Rakowe Tandem 16: cheapest two-seater
The Rakowe is the cheapest two-seater we review: a reinforced long seat on a 16-inch folder, rated by Rakowe for an adult plus a child or lightweight passenger, with dual disc brakes, lights and 85% pre-assembly. Despite the name, its review describes a long seat with no second set of pedals.
It is also the clearest example of the red flag on this page. Rakowe publishes no payload, no battery capacity ("48 V removable" with no amp-hours) and no top speed, and its "UL Certified" claim names no standard. Treat it as a bike for a child or a light adult on short trips, and ask Rakowe for the payload rating before carrying anyone heavier. Rakowe sells a dearer version of the same platform with a 749 Wh battery and a stated UL 2849 certification.
Legal status: unknown. With no stated top speed, nobody can say which class it is. Its review notes that the 750 W peak motor is modest enough that it is probably inside 20 mph, and that "probably" is not a compliance answer. Read the Rakowe Tandem 16 review.
7. KAKIGO Two-Seater Trike: best three-wheel option
The KAKIGO is for couples who want to ride together on one machine: a wide two-person bench with safety belts, rated to 330 lb combined, on a folding trike with a rear differential, 20 x 4 fat tires and anti-tip wheels in the box. Its 90 Nm of torque is the most on our trike shelf, and the 748.8 Wh battery is UL 2849 certified, named on the listing. The 330 lb rating leaves 150 lb behind a 180 lb rider, so check it against your actual pair. Plan on about 25 miles with two aboard, against the 80-90 claimed. It ships in two boxes with the charger in the second, so it may not be rideable the day it arrives, and it is a weak seller and the dearest pick.
Legal status: class unknown. The listing states 20 mph but only a 1,350 W peak motor, never a rated figure, so the class cannot be determined. If KAKIGO confirms a rated motor at 750 W or below, the 20 mph cap makes it a Class 2, so ask for the rated wattage in writing before you buy. Its belted bench is the kind of designed passenger seat the "designed and equipped" rules describe. Read the KAKIGO Two-Seater Trike review.
