TST City Commuter

A 750W rated hub motor sits exactly on the federal ceiling most states copied: all but one US state cap e-bikes at 750W (Oregon alone allows 1,000W). That matters here: this bike's rated figure is street-legal-shaped, and the peak number in the title (2000W now, 1500W on the listing we first reviewed) is output under load, which statutes don't measure. Speed is where you have to pay attention. TST markets this frame in more than one configuration, and the listing title now advertises up to 28 mph. The bike has a throttle, and the listing never says the throttle stops at 20 mph. A Class 2 throttle stops at 20 mph and Class 3 assist works only while you pedal, so unless the throttle cuts out at 20 mph, the 28 mph setting fits no US e-bike class. Ride it at the 20 mph setting, where it is a Class 2: check the display's settings menu on arrival, confirm the cap, and read our street-legal guide for where Class 2 bikes can go before you ride.

720Wh is genuinely big for $529.99 (as of Oct 8, 2:10 PM EDT, subject to change); the Heybike Cityscape 2.0 carries 468Wh for $599 (as of Oct 8, 2:10 PM EDT, subject to change). The seller's "up to 60 miles" assumes lowest assist, flat ground, and a light rider; fat tires at 4" wide cost meaningful rolling resistance, so treat 30-40 miles of mixed PAS riding as the planning number. The pack is removable and charges in a claimed 6-7 hours. No UL 2849 or UL 2271 certification is mentioned anywhere on the listing. If your building asks for certification before indoor charging, or you buy in New York City (where Local Law 39 bans the sale of uncertified e-bikes) or in California after SB 1271's January 2026 sale rules, that absence is disqualifying; look at the Funhang City 26 (UL 2271 and UL 2849, both certified by SGS) or the Hoverfly OUREA instead, both listing UL 2849 and both cheaper at our last check.

Front and rear suspension at this price usually means basic spring units, not adjustable dampers: fine for potholes and kerbs, not for actual trails. Combined with 20 x 4-inch fat tires that should soften broken pavement, though at a weight cost: TST now lists 66 lb and a 450 lb maximum load, which is worth knowing if the bike must climb apartment stairs. The brakes are front and rear mechanical discs: adequate at the 20 mph setting, and one more reason not to use the 28 mph one, so budget for pad checks.

Buy the TST if you want the most battery and suspension per dollar on Amazon right now, your commute has rough pavement, and certification isn't a gating requirement. Skip it if you need documented UL certification or a dealer network. The Gotrax R7 costs more but comes from a brand with a US support operation, and the Heybike Cityscape 2.0 remains our benchmark commuter if the budget stretches.
