TST Adult Electric Bike — 750W (2000W Peak), 48V 15/25Ah, Fat Tire
Product description
High-output motor: The bike is fitted with a 750W rated motor capable of 2,000W peak output and selectable speed/assistance levels (2–3 speed settings). It reaches roughly 28 mph in the highest unlocked mode and offers pedal-assist plus full-throttle operation.
Removable, fast-charging battery: Includes a 48V removable lithium battery (standard 15Ah; 25Ah option available on some configurations). A full charge takes about 6–7 hours. In conservative pedal-assist use you can expect up to roughly 50–65 miles; pure throttle operation is closer to the 40-mile range depending on rider weight and terrain. The pack is designed to be water-resistant and has anti-theft features for safer storage and indoor charging.
Ride components and handling: The frame supports a large 20" x 4" puncture-resistant fat tire setup for extra traction on snow, sand and rough trails. Front and rear suspension dampen bumps and reduce rider fatigue. The bike uses mechanical disc brakes for dependable stopping power and a professional 7-speed derailleur system to tackle varied gradients.
User interface and lighting: A handlebar-mounted LCD shows speed, trip distance and battery level so you can manage power use. High-output front LED lighting improves nighttime visibility while a rear taillight provides reflection and signaling functions to warn other road users.
Assembly, weight and warranty: The e-bike arrives about 90% pre-assembled; the package includes the bike with removable battery, owner manual and access to an assembly video. It weighs roughly 87.67 lbs and supports up to 450 lbs load. The manufacturer provides a 180-day warranty and online customer support for setup or service questions.
Practical notes: Because some final setup is required, expect to tighten bolts, align brakes and adjust the seat and controls. The removable battery makes charging and theft prevention easier, and the combination of fat tires, suspension and motor power suits both daily commuting and light off-road riding.

VerdictThis TST electric bike delivers strong acceleration from its 750W continuous (2,000W peak) motor and long range from a removable 48V battery. The fat 20x4 tires and dual suspension make it comfortable on mixed terrain while the mechanical disc brakes and bright lights improve safety. Expect some on-bike setup and occasional tuning — but for riders wanting power, a roomy payload and a long-range co

Happy with the purchase so far
We’ve only ridden a few times but are pleased. Very sturdy with strong top speed. First bike took longer to assemble; the second went much faster.

Absolutely fantastic performance
Super fun and fast. You can switch assistance classes; high mode is around 28 mph and the middle mode is in the low 20s. Handling feels well-executed and the build seems durable. Great value for the capability offered.

Solid option for experienced older riders
Very enjoyable ride. I followed video guides for the final assembly — flip the bike for seat installation. Tight spacing around the seat bolts makes access tricky; leave hardware loose until you can maneuver the seat into place. The stock saddle sat too low for me (I’m 5'10"), so I added spacers under the post and that solved it. The throttle pushes the bike to about 28 mph without pedaling. I did a 20-mile outing and only saw one bar drop, so range looks promising. Very comfortable overall.

Well-made and fun to ride
Came well packaged and was simple to finish assembling. The frame feels robust and the electric assist has ample power. Battery life has been reliable for my rides, and the overall ride quality is smooth. Controls are intuitive and build quality exceeded my expectations. Support was responsive. Very pleased and would recommend it.

Good commuter with some setup issues
Assembly was straightforward but the front rotor arrived slightly warped and rubbed; I had to replace it at a shop after no initial reply from the seller. The bike runs well otherwise, though the front brake squeaks and will need adjusting. I use it for a 7-mile commute; battery performs OK but throttle usage eats more charge.

Some mechanical know-how helps
I bought two for my partner and myself. These aren’t polished like premium brands — fitment and finishing are the main differences — but they’re a great value. Expect to tweak brakes and make minor adjustments. Unlocked top speed is about 27–28 mph. After a few dozen miles everything settled, though the brakes did need attention and squeaked until serviced.

Sturdy, comfy and user-friendly
Solid construction and durable tires. The display is easy to read and the saddle is comfortable for longer trips. There’s an app you can use to tweak top speed if desired. The rear light doubles as an indicator when you use the right control. Customer support is working through a few outstanding items. Ride safely.
