⌦ Design and Features
The Burchda RX80 impresses from the first glance with its robust and modern design, featuring those large FAT bike wheels and powerful suspension arms. Let’s see what it has to offer.
⧪ Frame and Materials
First of all, both the frame and the front fork are made of aluminum, a lightweight material that makes it easy to maneuver and transport when needed.
The geometry of this frame is quite comfortable and allows for easy mounting on the bike. It also makes it unisex and suitable for people from 1.70 to 1.98 meters.
Combined with the rest of the components, this e-bike has a weight of 33 kg, which is not excessive considering the super-sized 26 x 4.0″ wheels, the extra 17.5 Ah battery, and the motor, which are already quite heavy.
⧪ Brakes and Transmission
Safety is a priority on the Burchda RX80, which is evident in its 160 mm hydraulic disc brakes.
Compared to mechanical brakes, these hydraulic brakes do not require as much pressure on the levers and, in return, provide better braking performance.
This allows you to maintain full control of the bike in emergency situations and ensure safe riding at all times.
Regarding the transmission, this bike comes with an 8-speed Shimano Tourney gear.
It’s a rather simple entry-level Shimano gear, but it’s easy to adjust and provides enough gears to match your pedaling to the motor’s pace.
⧪ Suspension and Wheels
Another highlight of the Burchda RX80 is its full suspension with oil shocks in the front fork and the central part.
The front suspension, in particular, is interesting as it’s made of aluminum and has a lockout, allowing you to adjust the rebound or lock it if necessary.
The travel in millimeters for these suspensions is 100 mm in the front and 35 mm for the rear shock.
This feature greatly enhances comfort by absorbing terrain irregularities, even if you want to do mountain biking, but it’s not a professional suspension that would allow for trail riding or downhill.
Being a FAT Bike, the tires are extra wide and also large (26 x 4.0″), adding more comfort and stability to the overall ride.
The RX80 also incorporates extra-wide fenders so you can ride in the rain without getting your clothes dirty.
⧪ Comfort and Accessories
The Burchda RX80 has been created with the cyclist’s comfort in mind, adapting optimally to all heights through its adjustable features.
For example, it offers the possibility to modify the seat height, ensuring precise adaptation for any user, regardless of their height.
The seat, in addition to being spacious and comfortable, has springs that smooth out imperfections in the road, providing a smooth and pleasant ride.
On the handlebars, you’ll find ergonomically designed grips for maximum comfort, accompanied by a large color LCD screen.
This screen provides details such as the battery status, the selected driving mode, and various metrics like current, maximum, and average speed, distance of the last trip, and accumulated distance.
Additionally, this e-bike comes with other accessories that make it more like a motorcycle, such as the powerful 600 lm front light and the built-in mobile phone holder on the handlebars.
It also incorporates a built-in rear light on the seat, an important detail that makes it safer on urban roads.
⌦ Performance: Motor and Battery
One of the standout features of the Burchda RX80 is its performance, especially in the 750W version, although all models come with a powerful 17.5 Ah battery.
⧪ Power and Speed
The RX80 is available in 250, 500, and 750W versions, although in practice, these motors can reach higher power peaks.
For example, the 750W motor reaches peaks of 1000W, more than enough power to reach 28 mph (45 km/h) or even exceed this speed.
The 250W motor, on the other hand, complies with the legal limits in most countries and declares a maximum speed of 15 mph (25 km/h), although it may exceed this in practice.
In any case, this e-bike has enough power to carry up to 150 kg of weight and climb slopes of up to 30º.
⧪ Battery and Range
The next strong point of the RX80 is its high-capacity lithium battery, which is also removable and can be charged outside the bike for added convenience.
With its 17.5 Ah, this battery provides a respectable performance of 840 Wh, which translates to a range of up to 34 miles (55 km) in pure electric mode.
In assisted mode, this e-bike can easily cover between 50 and 62 miles (80 – 100 km) depending on the load and the selected assistance level.
Additionally, it comes with a fast charger that can charge the battery in 4 – 5 hours, which is quite fast for such a high capacity.
⧪ Assist Modes
The Burchda RX80 also stands out for its adaptability, offering up to 5 levels of assistance to meet the cyclist’s demands. These are as follows:
- Level 1: Gentle Assistance. Provides assistance up to speeds of 9 mph (14 km/h).
- Level 2: Balanced Assistance. Helps achieve speeds of up to 12 mph (19 km/h) with minimal effort.
- Level 3: Medium Assistance. Enables speeds of up to 18 mph (29 km/h).
- Level 4: Strong Assistance. Assists in reaching speeds of up to 22 mph (35 km/h).
- Level 5: Full Assistance. Reaches speeds of up to 28 mph (45 km/h) without the need for pedaling.
Cyclists can conveniently select these modes from the control located on the handlebars, allowing for intuitive adjustment of the electric motor support based on the ride and personal preferences.

⌦ Advantages and Disadvantages
Below, we’ll highlight the key advantages and disadvantages of this powerful electric FAT bike:
|5 Levels of Assistance

The Burchda RX80 presents itself as a good alternative in the field of electric FAT bikes, offering a balance between power, design, and functionality.
Its advantages, such as the 5 levels of assistance, a large 17.5 Ah battery, full suspension, or hydraulic brakes, are features worth considering.
However, like any product, it has its disadvantages, particularly its considerable size and weight and the lack of foldability.
In any case, if portability is not one of your priorities, the RX80 is a very good choice if you are looking for a comfortable and powerful e-bike.
