TS TST GRP LLC R004 E-Bikes - Review and opinions
Is it worth it?
If you want a fat-tire e-bike that can handle neighborhood rides, light off-road paths, and daily errands without jumping to a much higher price tier, this TST R004 lands in a useful middle ground. The 750W motor with 1500W peak output, 48V 15Ah removable battery, dual suspension, and 20 x 4 tires give it the kind of setup that feels built for comfort and stability first, not ultralight portability. The trade-off is weight and bulk, so this is not the bike to choose if easy lifting or compact storage matters most.
It makes the most sense for riders who want a stable, comfortable adult e-bike with real range claims, a removable battery, and enough power for mixed pavement use. Skip it if you need a lighter commuter, a folding frame, or a bike whose main appeal is simple garage-to-curb convenience. At this price level, the real question is whether you value the full-suspension fat-tire ride more than the extra handling and ownership friction that come with a 66 lb build.
| Motor power | 750W with 1500W peak |
|---|---|
| Battery capacity | 48V 15Ah |
| Claimed range | up to 60 miles in PAS mode |
| Maximum assist speed | 28 MPH |
| Brake type | Mechanical disc brakes |
| Wheel size | 20 inches |
Removable Battery
The 48V 15Ah battery comes off the bike and charges in about 6 to 7 hours.
That matters because it makes the charging routine easier to live with at home or in a garage, and it also reduces the hassle of parking near an outlet. The practical caveat is that the battery convenience does not change the bike’s overall size or weight, so storage still takes real space.
Power and Assist
The motor is rated at 750W with 1500W peak output, and the bike also uses 7 speeds plus three riding modes.
That combination gives the R004 a broader use range than a basic neighborhood cruiser, especially for riders who want help on hills or want to vary effort on longer rides. The trade-off is that the bike is built around support and stability, not featherweight handling.
Comfort and Control
Dual suspension, 20 x 4 fat tires, and mechanical disc brakes shape the way this bike feels on the road.
The ride should feel steadier over bumps and rough patches, while the brakes and lighting package make it easier to stay composed when conditions are less than ideal. The limitation is simple: the same comfort setup that smooths the ride also makes the bike heavier and less convenient to move around by hand.
Use evaluation
On a typical suburban ride, the first thing this bike gives up is lightness, and the first thing it gives back is confidence. The 20-inch fat tires, dual suspension, and 450 lb max load create a planted feel that suits slower streets, rough patches, and short errands where stability matters more than quick handling. That combination makes it feel like a practical cruiser with extra muscle, not a nimble city bike, so the fit is strongest for riders who want comfort and a steady stance over easy carrying.
For daily charging, the removable 48V 15Ah battery is one of the clearest ownership wins here. A full charge in 6 to 7 hours fits an overnight routine, and the battery can come off the frame instead of forcing the whole bike near an outlet. The range claim is broad enough to cover a long commute or a weekend loop, but the real buying value is simpler: this is a bike that can cover regular use without making every ride feel like a careful battery-management exercise. That said, the 66 lb weight keeps it firmly in the garage-bike lane, not the apartment-stair lane.
The power package is the other reason this model stands out in its price band. A 750W motor with 1500W peak output, 7-speed gearing, and three riding modes gives it enough flexibility for hills, flats, and mixed effort riding, while the LCD display keeps speed, distance, and battery level easy to track. In real use, that means the bike is set up for riders who want assistance to feel useful and adjustable, not fussy. The flip side is that the bike’s appeal comes from the whole system working together, so it is best for buyers who want a sturdy all-rounder rather than a stripped-down commuter.
Safety and control are handled in a practical, no-drama way. Mechanical disc brakes, a bright front light, rear light, and full suspension create a setup that is more reassuring for evening riding and rough pavement than a bare-bones e-bike. The 20 x 4 tires add grip and visual stability, which helps the bike feel secure when the surface gets uneven. The trade-off is that this comfort-and-control package adds bulk, so the bike rewards riders who care about ride confidence more than easy transport.
Pros
- Stable fat-tire ride with dual suspension for rougher pavement and casual mixed-surface use.
- Removable 48V 15Ah battery with a practical charging routine.
- Good power-to-price balance for riders who want assist, gearing, and range without moving up-market.
- Bright front and rear lights plus disc brakes add everyday control.
Cons
- 66 lb weight makes lifting, carrying, and tight storage inconvenient.
- Mechanical disc brakes are solid, but they are not the more premium brake setup some riders want.
- Range is strong enough for normal use, but battery life feedback is mixed across ownership experiences.
- The bike’s comfort-first build adds bulk, so it is not the best choice for apartment storage or frequent transport.

User reviews
The strongest pattern here is easy to read: riders are happiest when they want a stable, fun, good-looking fat-tire bike that feels easy to assemble and comfortably quick for everyday use. The complaints cluster around shipping damage, occasional setup friction, and battery or component issues on a smaller share of orders. The practical lesson is that this bike sells best as a comfort-first value play, not as the kind of purchase where ultra-clean ownership is the main reason to buy.

This bike looks amazing and rides smooth. It goes up to 28 mph on class 3, and the app unlock made that part of the experience stand out for me.

I built it myself and it was super quick and easy. The battery lasts about 30 miles on purely electric, which is perfect for how I use it.

I ride it all the time, and when I had a problem with my crank, customer service helped me get back on the road.

Easy to assemble and exactly as advertised. The range has been great, and it handled a nearby hill without any issues.

Against the TS TST 1500W Retro E Bike, the R004 sits in the same family of fat-tire, 20-inch, 1500W-peak adult e-bikes, so the choice comes down to the ride flavor and price lane rather than a dramatic capability gap. If you want the same basic comfort-and-power formula with a stable, full-suspension setup, the R004 is the straightforward pick; if you are shopping the broader TS TST line, the decision is mostly about which version offers the better fit and deal on the day.
Compared with a compact folding e-bike route like the YorkE 1000W Folding Electric Bike, this TST is the opposite answer. The YorkE lane makes more sense when storage, lifting, and mixed transport matter most; the R004 makes more sense when you care more about a planted fat-tire ride, removable battery convenience, and a more relaxed comfort setup. If your bike has to live in a small apartment, folding wins. If it has to feel steady and cushioned on the road, this one is the better route.

Is the TS TST GRP LLC R004 electric bike worth it?
The R004 is a strong buy for riders who want a comfortable fat-tire e-bike with real everyday usefulness: removable battery, dual suspension, disc brakes, lights, 7-speed gearing, and enough motor output to make hills and longer rides feel manageable. At this price, it offers a convincing mix of comfort and capability, and it is easy to see why it appeals to riders who want a stable, good-looking bike that feels ready for regular use. If you are checking the current offer, this is the kind of model that makes sense when you want more ride confidence than a basic commuter can give you.
The main reason to skip it is also clear: the 66 lb build and non-folding frame make it a poor fit for frequent lifting, tight storage, or apartment life. Mechanical disc brakes and a comfort-first layout are perfectly serviceable, but they do not erase the bulk. If portability is your top priority, choose a folding route instead; if comfort, range, and a planted ride matter more, this is the better bet.
