Key Features

This level of power provides:

The motor also produces roughly 115 Nm of torque, helping the bike maintain speed even on steep hills.
If you’re comparing motor sizes, see the guide on motor wattage explained for e-bikes.
Long-Range Battery
The Thunder Pro includes a 52V 20Ah battery, which equals about 1040 watt-hours of capacity.
Charging time is typically 5–6 hours for a full charge.
Estimated range:
| Riding Style | Range |
|---|---|
| Low pedal assist | 70–90 miles |
| Mixed riding | 45–65 miles |
| Heavy throttle | 30–45 miles |

Fat Tire All-Terrain Design
The 26 × 4 inch fat tires provide excellent traction on loose surfaces such as:
• sand
• snow
• gravel
• dirt trails
The large tires also help absorb road vibration, improving comfort during longer rides.
Full Suspension System
Unlike many budget fat-tire e-bikes, the Thunder Pro includes both front and rear suspension.
This improves comfort on:
• off-road trails
• rough pavement
• potholes or uneven terrain
Integrated Safety Lighting
The bike includes:
• front headlight
• rear brake light
• turn signals
These features improve safety when riding at night or commuting in traffic.
Display and Tech Features
The Thunder Pro includes a backlit LCD display showing:
• current speed
• battery level
• pedal assist level
• trip distance
• ride mode
Additional features include:
• twist throttle
• cadence pedal assist sensor
• Shimano 7-speed gearing
• removable locking battery
Battery and Range
The large 52V 20Ah battery is one of the bike’s biggest advantages.
Under ideal conditions, riders may reach up to 90 miles of range, although real-world riding typically falls between 45 and 70 miles depending on terrain and throttle use.
Higher speeds and steep hills will reduce range significantly.
Ride Quality
Acceleration
The Thunder Pro accelerates much faster than most commuter e-bikes thanks to its powerful motor.
Many riders report strong launch power even on hills.
Stability
The fat tires and heavy frame make the bike feel very stable at higher speeds.
This is especially noticeable when riding on:
• gravel roads
• forest trails
• uneven pavement
Comfort
Comfort features include:
• padded saddle
• fat tires acting as secondary suspension
• full suspension system
However, the 82-pound weight makes the bike difficult to lift.
Unboxing and Assembly
The Thunder Pro typically arrives about 85 percent assembled.
Final assembly usually involves:
• installing the front wheel
• attaching handlebars
• installing pedals
• adjusting brakes and gears
Most riders complete assembly in 30–45 minutes using the included toolkit.
Reported Testing and Performance
Independent reviewers report:
• Top speed: about 30–35 mph
• Acceleration: roughly 0–20 mph in about 5 seconds
• Hill climbing: capable of steep inclines
• Range: around 45–70 miles in mixed riding
The bike performs well on gravel, dirt trails, and sand thanks to the fat tires and high torque motor.
What Riders Are Saying
Feedback from owners and reviewers of the Jasion Thunder series highlights the bike’s strong motor power, comfortable ride, and value for the price, though some riders note that the bike’s weight and entry-level components reflect its budget category.
Positive Rider Feedback
“First I will say it’s pretty comfortable… the twist throttle is a great addition and it’s pretty quick to 30 mph.”
“On mild trails it’s fantastic… I’d say it’s worth the $1000 price tag.”
“Fat tires seem indestructible and great on many surfaces.”
“Seems like a pretty good deal coming in right under $1K.”
“According to the total mile calculation, I’ve put about 1000 miles on it in six months and it’s still running great.”
Many riders say the Thunder Pro delivers strong acceleration and a smooth ride thanks to its fat tires and large saddle, making it suitable for commuting, recreational riding, and light off-road use.
Criticisms Riders Mention
Some riders also point out a few limitations that are common with budget fat-tire e-bikes.
“At 82 lb, the Thunder is heavy.”
“The handlebars are way too low for anyone over 5’5.”
“The build quality is really disappointing. The welds are sloppy and minimal.”
“There wasn’t that initial bite when braking… I had to plan my braking in advance.”
“Their customer service was finally responsive… after I sent about five or six emails.”
These comments suggest that while the Thunder Pro offers strong performance for the price, some riders notice compromises in weight, component quality, or customer support responsiveness.
