Some owners get a fun, solid bike for the money; others get a bent derailleur, a broken folding hinge or a battery fault, so treat this as a lower-cost option where a first inspection and possibly a local bike shop visit are worth planning for.

More from this brandAll TS TST GRP LLC electric bicyclesOverview
The TST F00B is a 20-inch fat-tire folding ebike with a 1200W peak motor, SGS and UL2849 certification, and a claimed 40-60 mile range on pedal-assist or pure electric mode. It folds in a claimed 3 seconds without tools and includes a 7-speed LCD display.
TST's listing promotes a Class 2 to Class 3 speed classification and dual charging methods for the removable battery. Review reports split sharply: several owners call it a well-built, fun bike for the price, while others describe a bent derailleur out of the box, a folding hinge that snapped, and a range well short of the advertised 40-60 miles.

- 40-60 mile claimed range, dual charging methods

Who it's for
Works for a budget-focused buyer willing to accept some risk of quality control issues in exchange for a low price folding fat-tire ebike. Not a fit for anyone who needs the bike to work reliably right out of the box without a trip to a local shop.
Pros and cons
- Fun, sporty ride quality noted by several owners
- 180-day warranty with a stated 24-hour support response
- Derailleur reported bent out of the box on at least one unit
- Folding hinge reported breaking during normal use
- Real-world range reported under 40 miles versus the advertised 40-60 mile claim
- Battery undervoltage error reported at low charge on one unit
Performance notes
The 1200W peak motor is rated to climb 30-degree slopes with the PAS system switching between pure electric, pedal-assist and manual modes. Actual range reported by owners runs under 40 miles rather than the advertised 40-60 mile window, and battery undervoltage errors have been reported at the lower charge levels.

Frequently asked questions
How far can the TST F00B actually go on a charge?
TST advertises 40-60 miles, but reviewer reports of real-world range run under 40 miles, so expect the lower end of or below the claimed range depending on rider weight and terrain.
What if I get a battery error?
One reviewer reports a recurring undervoltage error at low charge levels and describes a slow warranty response; contact TST support and expect the stated 24-hour response window.
