Vivi C26UL 500W Step-Through Cruiser

The 500W rated rear hub is adequate for a flat-ground city cruiser; the 1000W figure Vivi markets is a brief peak, not sustained output. Class 2 means a throttle to 20 mph without pedaling plus pedal assist to the same cap. There is no Class 3 (28 mph) mode, so if you want road speed beyond 20 mph, look at a Class 3 commuter such as the Heybike Cityscape 2.0, $609 (as of Sep 29, 8:10 AM EDT, subject to change).

The 374.4 Wh battery is small for a 26-inch cruiser. Vivi advertises 22-25 miles on the throttle and 44-50 miles with pedal assist. At the roughly 17-20 Wh per mile a cruiser like this draws in mixed riding, plan on about 18-22 miles per charge, and less in cold weather. The battery is removable, so you can charge it indoors without bringing the bike inside.

UL 2849 is the e-bike electrical-system standard, and it incorporates UL 2271 battery testing by reference. The original Vivi C26 listing names SGS as the body that certified it, which is the checkable kind of claim. NYC Local Law 39 of 2023 bans the sale, lease or rental in New York City of e-bikes and e-bike batteries not certified to UL 2849 or UL 2271, California's SB 1271 requires certification for e-bike sales from 1 January 2026, and some apartment buildings ask to see the certificate before allowing indoor charging.

The complication is stock. The certified listing is backordered, and no other C26 listing is live. If you need a certified step-through now, choose a bike whose in-stock listing names the lab, such as the Funhang City Cruiser 26 at $319.99 (as of Sep 29, 8:10 AM EDT, subject to change).

The low step-through is the defining choice here. If swinging a leg over a top tube is difficult because of knee, hip or balance limits, this shape removes the problem. Vivi publishes a 56 lb weight and a 330 lb payload. The geometry is an upright cruiser position suited to short city rides rather than long distances.

Mechanical disc brakes front and rear, which need periodic cable adjustment and have less modulation than hydraulic brakes. A basic front suspension fork, a 7-speed Shimano drivetrain, cadence-sensor pedal assist that switches power on and off rather than ramping with effort, and an LCD display. Vivi advertises a 1-year warranty on the motor, battery and charger, and Amazon's return window applies to Amazon orders.

Buy this if you want a low step-through frame for easy mounting, your rides are flat to rolling and under about 10 miles each way, and you accept budget components. Skip it if you live somewhere hilly (a 500W cadence-sensor hub strains on long climbs), if you want Class 3 road speed, or if you need a bike now while the listing is backordered.
