Thunder Pro vs RetroVolt Specs
Top speed
The Jasion Thunder Pro ST claims a top speed of 35 MPH. This model accelerates from 0 to 20 MPH in under 5 seconds, offering rapid bursts of speed for highway cruising or steep climbs. The Jasion RetroVolt reaches a maximum speed of 30 MPH. While both bikes use 2000W peak motors, the Thunder Pro ST delivers slightly higher velocity. You will notice the difference on open roads where the extra 5 MPH provides a tangible performance edge for faster travel.
Battery range
Range is a major factor for long-distance riders. The Thunder Pro ST features a 52V 20Ah battery with a total capacity of 1040Wh. This large pack supports up to 90 miles of range in pedal-assist mode and 35 miles in pure electric mode. The RetroVolt data lists a maximum range of 70 miles but does not specify the battery voltage or amp-hour capacity. If you prioritize distance between charges, the Thunder Pro ST offers a verified extended range that exceeds the RetroVolt's stated limit.
Wheel size
Wheel diameter affects ride stability and terrain handling. The Thunder Pro ST is built on 26-inch fat tires, which are standard for adult fat tire e-bikes. This size offers a balance of rolling efficiency and obstacle clearance. The RetroVolt uses 20-inch by 4-inch fat tires. Smaller wheels can make the bike more compact and easier to maneuver in tight spaces, but they may feel less stable at high speeds or over large bumps. Your choice depends on whether you prefer stability or compactness.
Suspension system
Ride comfort relies heavily on suspension quality. The Thunder Pro ST is explicitly described as a full suspension fat tire electric bike. This means it has both front and rear shock absorption to smooth out rough trails and urban potholes. The data for the RetroVolt does not mention a suspension system. Without specified suspension, the RetroVolt likely relies on the cushioning of its wide tires alone. If you plan to ride on uneven terrain, the full suspension on the Thunder Pro ST provides superior comfort and control.
Motor torque
Torque determines how well the bike climbs hills and accelerates from a stop. The Thunder Pro ST motor delivers 115N·m of torque. This high torque output helps it handle steep inclines and heavy loads with ease. The RetroVolt motor provides 99Nm of maximum torque. While both are powerful, the Thunder Pro ST has a higher torque rating. This gives it an advantage when carrying heavier riders or navigating challenging grades where extra pulling power is necessary.
Braking system
Stopping power is critical for safety, especially at higher speeds. The Thunder Pro ST is equipped with hydraulic oil disc brakes. Hydraulic systems provide consistent, strong stopping force with less hand effort, which is important for a bike that can reach 35 MPH. The RetroVolt specifications do not list the type of brakes used. You cannot verify if it has hydraulic or mechanical brakes. For confident stopping performance, the Thunder Pro ST offers a clearly superior braking setup.
Which Jasion Model Suits Your Ride
Long-distance commuters needing max range
The Thunder Pro ST offers a 1040Wh battery for up to 90 miles of range. Its 52V 20Ah pack supports extended journeys without frequent recharging. You get 35 miles on pure electric power alone. This capacity ensures you cover more ground between charges compared to the shorter range alternative.
Riders prioritizing top speed and acceleration
This model reaches 35 MPH with 115N·m of torque. It accelerates from 0 to 20 MPH in under 5 seconds. The higher top speed and faster acceleration provide more dynamic performance for steep hills or highway cruising. You get quicker response times when you need to merge or climb.
Those seeking a compact, portable frame
The RetroVolt features 20-inch wheels for a smaller footprint. Its frame height is 50 inches and length is 67 inches. This compact design is easier to store in tight spaces. You get a nimble ride that is simpler to maneuver in urban environments or transport in smaller vehicles.
Budget-conscious buyers wanting basic utility
This model provides a 70-mile range and 30 MPH top speed. It includes a 7-speed transmission and four riding modes. You get essential features like fat tires for traction. The simpler spec sheet focuses on core functionality without the extra range or speed of the larger frame.
