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.

Overview
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.

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.
What buyers say
From Amazon customer reviews.
Buyers who got a clean unit call it well built, fun to ride and worth the price, with several noting easy assembly using the included tools. Others report a bent derailleur out of the box, a folding hinge that snapped during normal use, rubbing brakes, a battery undervoltage error, and real-world range well under the advertised 40-60 miles.
Strengths and trade-offs
Drawn from this product's published specifications.
- Well packaged on arrival with tools included for assembly, per multiple reviewers
- 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.

Questions about the TS TST GRP LLC F00B
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
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.
Is the folding hinge reliable?
Most reviewers report normal folding without issue, but at least one reviewer's bike broke at the folding hinge during ordinary use, so handle the fold point carefully.
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.
