Radmini Step-Thru 2 vs. Radmini 4
After riding the Radmini Step-Thru 2 and RadMini 4 for several months, I have had a chance to evaluate their strengths and weaknesses. In this section, I will share my thoughts on each aspect of the bike. I’ll be comparing both based on the following factors:
- Design and Build
- Display and Screen Technology
- Battery Life
- Motors Comparison
- Weight Comparison
- Connectivity and Ports
Continue reading to see the differences between the Radmini Step-Thru 2 and the Radmini 4.
Design and Build
The Radmini Step-Thru 2 and Radmini 4 are folding electric bikes but have different designs and builds. The Radmini Step-Thru 2 has a sleek, modern design with a black frame and white accents. The tires are also black with white walls. This bike has a step-through frame, making it easy to get on and off and a great choice for people with limited mobility or carrying cargo.
The Radmini 4 has a more traditional design, with a black frame and red accents. The tires are also black. This bike has a traditional diamond frame, which is more common on electric bikes.
If I had to choose one bike based on appearance, I would probably choose the Radmini Step-Thru 2. I like the sleek and modern design, and I think the black-and-white color scheme is sharp.
Display and Screen Technology
The Radmini Step-Thru 2 has a backlit LCD display. This display is easy to read in direct sunlight and shows important information like speed, battery level, and pedal assist level. It also has a USB port, so you can charge your phone or other devices while you’re riding.
On the other hand, the Radmini 4 has a color LCD display. This display is even easier to read than the backlit LCD display on the Radmini Step-Thru 2, and it also shows more information, like distance traveled, time ridden, and calories burned. It also has Bluetooth, so you can connect it to your phone to use the Rad Power Bikes app.
So, which display is better? Well, that depends on what you’re looking for. If you want a display that’s easy to read in direct sunlight and shows all the essential information, then the Radmini Step-Thru 2’s backlit LCD display is a great option. But if you want a display that’s even easier to read and shows more information, then the Radmini 4’s color LCD display is the way to go.
Personally, I prefer the color LCD display on the Radmini 4. It’s just so easy to read, and it shows me all the information I need to know about my ride. But if you’re looking for a more affordable bike, the backlit LCD display on the Radmini Step-Thru 2 is still a great option.
Battery Life
Both the Radmini Step-Thru 2 and the Radmini 4 have a 48V 14Ah (672 Wh) battery that can last for about 25 to 45 miles, depending on the terrain and pedal assist level. The battery takes 5 to 6 hours to charge fully.
The main difference between the two batteries is that the Radmini Step-Thru 2 has a Samsung battery, while the Radmini 4 has a Lithium-Ion battery. Samsung batteries are known for their reliability and long lifespan, while Lithium-Ion batteries are lighter and more energy-dense.
So, if you’re looking for a reliable battery with a long lifespan, the Radmini Step-Thru 2 is a good option. If you’re looking for a lightweight battery with a high energy density, the Radmini 4 is a good option.
Motors Comparison
The Radmini Step-Thru 2 and the Radmini 4 are both great e-bikes, but they have different motors. Both bikes have a 750-watt geared hub motor, which is powerful enough to easily tackle hills and obstacles. They both have a throttle, so you can get up to speed quickly without pedaling.
The main difference between the two motors is the top speed. The Radmini 4 has a slightly higher top speed of 25 mph, compared to 20 mph for the Radmini Step-Thru 2. This is because the Radmini 4 has a slightly different controller, allowing it to go faster.
Weight Comparison
The Radmini Step-Thru 2 weighs 69 pounds, while the Radmini 4 weighs 67 pounds. This means that the Radmini 4 is slightly lighter than the Radmini Step-Thru 2.
I’ve had the opportunity to ride both bikes, and I can honestly say that I don’t notice much of a difference in weight between the two bikes. Both bikes are easy to ride and maneuver, even when fully loaded.
The extra weight of the Radmini Step-Thru 2 is probably due to its slightly larger frame. The Radmini Step-Thru 2 has a step-through frame, which makes it easier for people to get on and off the bike. The Radmini 4 has a traditional diamond frame, which is slightly lighter.
Connectivity and Ports
Both bikes have similar connectivity and ports, but the Radmini 4 has a few key upgrades. They both have a USB port on the display that can be used to charge your phone or other devices. They also have a headlight that can be turned on and off from the display.
The Radmini 4 also has a color LCD display with Bluetooth connectivity, which allows you to connect the display to your phone to use the Rad Power Bikes app. The app allows you to track your rides, adjust the settings on your bike, and more. The Radmini Step-Thru 2 does not have Bluetooth connectivity.
The bikes use a 48-volt, 2-amp Rad Power Bikes smart charger that plugs into a standard wall outlet. Both bikes have a controller inside the frame, which can be accessed by removing some screws. The controller manages the power delivery and communication between the battery, motor, and display.
