Our take on the TST Electric Bike for Adults, 48V 15/25 Ah Battery, 60/100 Mile Range

The TST R004 is a budget fat-tire electric bike for adults, built around a 750W rear hub motor (2000W peak) and a 48V 15Ah removable battery rated at 720 Wh. TST claims up to 65 miles per charge, though real-world range on a 20x4 fat tire bike with a 750W motor will usually land well below that. It has 20x4 puncture-proof fat tires, a 7-speed drivetrain, an LCD display and linear pull brakes on an iron frame. At $529.99 at Amazon as of November 3, 2026, it sits at its only recorded price, so there is no discount history to judge against yet.

Best forBudget buyers wanting a fat-tire e-bike under $600
Riders on gravel, dirt and snow who want 20x4 tires
Commuters who want a removable battery to charge indoors
Shorter riders and casual riders who prefer 20-inch wheels
Pros
  • 750W motor with 2000W peak gives strong acceleration for the price
  • 48V 15Ah (720 Wh) battery is removable for indoor charging
  • 20x4 fat tires handle sand, snow and rough pavement
  • 7-speed gearing lets you pedal with or without assist
  • LCD display shows speed, battery and assist level
Cons
  • Iron frame is heavier than aluminum rivals
  • Linear pull brakes are weaker than hydraulic discs on a heavy fat bike
  • 65-mile range claim is optimistic for a 750W motor and 4-inch tires
  • 6-7 hour recharge is slow for a 15Ah pack
  • One seller and one price, so no competition to push the price down

Questions and answers

Is the TST R004 worth $529.99?
At $529.99 it is cheap for a 750W fat-tire e-bike with a 720 Wh removable battery. Expect budget components, especially the linear pull brakes and iron frame, rather than premium parts.
What is the real range on a charge?
TST claims up to 65 miles, but a 720 Wh battery with a 750W motor and 20x4 tires typically delivers roughly 20 to 35 miles with mixed assist. Expect closer to the low end if you use throttle heavily or ride hills.
How long does the battery take to charge?
About 6 to 7 hours from empty with the included charger. The battery is removable, so you can charge it inside away from the bike.
How big is it, and who fits?
It is a 20-inch wheel fat-tire bike, which suits riders roughly 5'3" to 6'2". Check the standover height and seat range before buying if you are at either end.
Does it come with fenders, a rack or lights?
The listed specs cover the motor, battery, tires, gearing, brakes and display only. Confirm what is in the box with the seller before ordering if you need fenders, a rear rack or lights.
When is the best time to buy?
It has held $529.99 at Amazon since at least October 30, 2026, with no lower price recorded. Watch for holiday sales, since e-bike discounts are common around Black Friday.
