Let’s begin with the motor! The Bafang Ultra M620 has been called the “diesel engine” of electric bikes, thanks to the high level of torque and power the motor provides the eBike and rider. Both the Ultra FS Pro 3 and the Scout are built with the same Ultra motor, and both benefit from the combination cadence and torque sensor. With equal power and pedal assist settings, let’s keep looking at what sets these two models apart from each other.

The first significant difference we come across is the battery capacity of both eBikes. The Juggernaut comes with a 52V 17.5Ah 910Wh battery, while the Scout has a 48V 17.5Ah 840Wh battery. The Juggernaut can also be equipped with dual batteries for up to 1794 Wh of power. Plain and simple, the FS Pro 3’s battery is more powerful, which translates to better range, longer rides, and superior performance. The Scout's battery is enough for riders planning shorter rides, but the Juggernaut is the clear winner for anyone looking for maximum range and power.

Let’s head to the scales! Both the Juggernaut Ultra FS Pro 3 and the Bakcou Scout are heavier than normal, non-electric bikes. The Scout is estimated to weigh 79 pounds with the battery installed, compared to the Juggernaut’s total weight of 81-84 pounds. While the weight difference is not substantial, it can make a difference for those who plan to lift or transport the bike frequently. However, it’s worth keeping in mind that the Juggernaut’s superior battery options can make up for the increased weight. 

In terms of customization, the Juggernaut is available in three frame sizes (17", 19", and 20") and three wheel sizes (26x4", 26x4.8", and 27.5"x3"). The Scout, on the other hand, is only available in two frame sizes (17" and 19") and one wheel size (26x4"). The FS Pro 3 also offers upgradable brakes and forks, while the Scout does not. With more options of frames, wheels, and upgrades, the Juggernaut Ultra FS Pro 3 is the better option for riders who want a perfect fit personalized to them.

If you’re planning to carry or tow cargo, pay attention to the payload! The Scout is rated to carry up to 300 pounds, compared to the FS Pro 3’s 265-pound rating. Some of our heavier riders have reported reduced performance on full-suspension bikes, which is why we’ve reduced our payload rating in contrast to our competitors. Still, the 35-pounds difference between the two eBikes is not significant and will likely not affect most riders.

Biktrix Juggernaut Ultra FS Pro 3 Pros and Cons


  • Larger capacity battery for longer rides through tougher terrain
  • Dual battery compatible for dramatically enhanced range and performance
  • Options galore, with multiple wheel and frame sizes plus upgradable components to choose from


  • Heavy, weighing between 81-84 pounds

Bakcou Scout Pros and Cons


  • Higher payload rating of 300 pounds
  • Available in two different frame sizes


  • Smaller battery capacity
  • No option for dual batteries
  • No options for component upgrades


While the Bakcou Scout has some impressive features, the Biktrix Juggernaut Ultra FS Pro 3 edges it out in terms of power, range, and customization options. The ability to add a second battery and upgrade brakes and forks make the Juggernaut Ultra FS Pro 3 a more versatile and customizable option. While it may be slightly heavier, the benefits and features of the Juggernaut Ultra FS Pro 3 make it the clear winner in this comparison.
