Today, we’re diving into the world of all-wheel electric bikes and exploring what makes them unique. If you live in an area with challenging terrain—like snow-covered roads, heavy rain, or muddy trails—you might be looking for a bike that can handle it all.

While we previously reviewed a model with strong off-road capabilities, if you need even more grip, traction, and performance, then a two-wheel drive (2WD) system could be the right choice for you. But how does it actually work?

At first glance, adding two motorized wheels seems straightforward. The idea is simple: install two motors to boost power, speed, or both. However, in practice, the maximum speed of a dual-motor electric bike won’t exceed the speed of a single motor. Physics doesn’t allow speeds to add up—so the main benefit isn’t speed, but rather increased traction and torque.

A 2WD system allows the bike to climb steeper hills faster, offer better acceleration, and perform well on rough surfaces like sand, ice, or mud. It also improves handling and stability when moving at high speeds or over uneven ground. Plus, it can carry heavier loads than a single-motor bike.

So why aren’t all electric bikes equipped with 2WD? The answer lies in the technical challenges. When two motors are used, there’s often an imbalance in power distribution and current consumption. The front and rear wheels may rotate at different speeds, leading to overheating or braking effects on one side.

To solve this, advanced electronic systems are needed—similar to those found in four-wheel-drive cars. These systems monitor and balance wheel rotation, ensuring smooth and safe performance. Delfast is currently working on developing such a solution to make 2WD bikes more reliable and efficient.

Another challenge is energy consumption. A dual-motor system uses about 25–30% more power. This means either larger batteries or hybrid solutions must be considered. Some manufacturers have already tested these approaches, balancing efficiency with performance.

Let’s take a closer look at the pros and cons of all-wheel electric bikes:

• Improved acceleration and handling
• Better traction on soft or slippery surfaces
• Increased carrying capacity
• Redundancy – if one motor fails, the other can still function

• No increase in top speed
• Higher weight and energy consumption
• More expensive than single-motor models

As you can see, the transition from traditional off-road bikes to 2WD models makes sense for those who prioritize performance and reliability. We’re excited to see what the future holds as Delfast continues to innovate in this space.
