The TST is built for riders who want fat-tire power without paying fat-tire prices. A 749 W motor with 2,000 W peak and a removable 48 V 15 Ah battery (720 Wh) are numbers usually found on bikes costing $700 or more, and Amazon lists up to 60 miles with pedal assist and a 6–7 hour charge.
Front and rear suspension and 20 × 4-inch tires make it comfortable on gravel, sand and broken pavement. Its standout figure is the 450 lb maximum load, the highest of any bike we review, which makes it a good option for heavier riders.
Where it saves money is in the details: mechanical disc brakes (Amazon's spec table even lists linear-pull brakes, which contradicts the description), a basic LCD, three riding modes, a steel frame and a short 180-day warranty. At 66 lb it's also on the heavy side.
With 469 ratings and a 4.3 average it has a large track record, though 10% of buyers gave it a single star, so inspect it carefully after assembly.
Best for: Heavier riders or anyone who needs a sturdy, comfortable fat-tire bike with lots of battery on a tight budget.
