Overview
A fat tire electric dirt bike from TST with a 1500W peak motor and 90 N.m of torque, built around a removable 48V battery in 15 or 30AH sizes for riders who want an off-road capable commuter with passenger capacity.
TST rates the battery to 60 miles or more depending on the AH size chosen, and the bike is UL 2849 tested by SGS. Several reviewers used it two-up with a child passenger on the included rear pegs and seat, and while most described the build quality as solid for the price, one detailed review flagged factory assembly issues including stripped bolts that blocked fender installation and disc brakes that are not actually hydraulic despite being described that way.
- 1500W peak motor, 90 N.m torque, 35 degree slope rating
- 48V 15 or 30AH removable battery, UL 2849 tested by SGS
- 20x4.0 puncture-proof tires with full suspension
- 360 degree LED lighting including headlight, brake light and turn signals
Who it's for
Suits riders who want a powerful fat tire e-bike for mixed street and off-road use and value a 35 degree hill-climbing rating and passenger capability. Less suited to buyers who need every listed spec to be exact out of the box.
What buyers say
From Amazon customer reviews.
Reviewers who researched multiple e-bikes before buying described the build quality, waterproof battery and torque as standout features, and several completed assembly in under an hour using the included tool kit. Passenger use came up repeatedly, with riders taking a child along on the rear pegs and seat without issue. One detailed review pushed back on specific claims, reporting stripped bolts from the factory that blocked front fender installation, misaligned welds limiting seat bolt attachment, and disc brakes that are not actually hydraulic and struggle to stop the bike, though this reviewer still called it a reasonable value for the price.
Strengths and trade-offs
Drawn from this product's published specifications.
- 1500W peak motor rated for 35 degree slopes
- Removable, waterproof 48V battery in 15 or 30AH sizes
- Passenger-capable with rear pegs and extended seat
- Straightforward assembly with a complete included tool kit
- One buyer found the disc brakes are not actually hydraulic as described
- Reports of stripped factory bolts blocking fender installation
- Only a 6-month warranty
Performance notes
The 1500W peak motor and 90 N.m of torque are rated to climb a 35 degree slope, and reviewers riding it two-up describe it as still powerful with a passenger aboard, though one warns to take off carefully with extra weight on board. Pure electric mode reportedly reaches 30MPH with strong torque, and switching to pedal or assist mode extends range for everyday commuting.
