Understanding the Basics
Definition of mid drive vs hub drive electric bike
A mid drive electric bike is a type of electric bike that uses a motor to drive the crankset and power the bike.
A hub drive electric bike is a type of electric bike that uses a motor to drive the rear wheel of the bike.
What is a Mid Drive Electric Bike?
A mid-drive electric bike is an ebike that has its motor mounted near the center of the bike, giving you smooth and efficient power delivery. This makes it an ideal option for riders looking for a reliable ride. Here are some of the advantages of a mid-drive motor:
What is a Hub Drive Electric Bike?
You’ll experience a different ride when opting for a hub drive electric bike. With its hub motor located near the wheels, you’ll be able to enjoy smooth power and effortless acceleration.
Hub drive electric bikes are powered by a motor situated in the center of the wheel, usually either the front or back wheel. This electric motor is connected to the bicycle’s existing drivetrain, and as you pedal, it will provide power to the wheel. This power is provided via a controller, which allows you to adjust the amount of power you want your bike to provide.
The hub drive electric bike also offers increased control over the bike’s power, allowing you to customize the ride to your preference. These electric bikes are generally simpler than mid drive electric bikes and are usually more affordable.
Core Differences Between Mid Drive and Hub Drive eBikes
Knowing the basic mechanisms of each and the role of positioning can help you make an informed decision.
Basic Mechanisms: Mid Drive vs Hub Drive
Comparing mid drive and hub drive ebikes, one major difference lies in their basic mechanisms. A mid drive motor is positioned at the center of the bike’s frame and powers the chain. The mid drive motor is much more efficient than a hub motor, as it takes advantage of the bike’s transmission system, resulting in more torque and speed.
A hub drive motor is located in the rear or front wheel and propels the bike when the wheel is turned. It’s also easier to maintain and repair. Hub motors are smaller and simpler to install.
The Role of Positioning: Why it Matters
Understanding the differences between mid drive and hub drive electric bikes requires considering the positioning of the motor.
A hub motor, as its name implies, is nestled in the heart of the bike’s wheel, specifically in the hub. It can be positioned either at the front or the rear, depending on the design and purpose of the eBike. The positioning plays a significant role in how the eBike handles and performs.
Front Hub vs Rear Hub
A front hub motor propels the bike forward by spinning the front wheel. This set-up, similar to front-wheel drive vehicles, provides a “pulling” sensation. It also improves traction and control on loose surfaces like gravel or snow. The front motor setup might feel a bit unnatural to some riders, as traditional bikes drive from the rear.
Rear hub motors, on the other hand, offer a riding experience that more closely resembles conventional cycling. By driving the rear wheel, they create a “pushing” sensation that’s familiar to most riders. Rear hub motors can often provide better handling and balance, as the weight of the motor is situated near the bike’s center of gravity.
Drawbacks for Hub Motor
The position of the hub motor can have some drawbacks. It’s further away from the bike’s center, which can affect the balance and weight distribution of the eBike, especially when cornering at high speeds or navigating steep slopes. This off-centered weight can also make changing a tire more challenging due to the additional heft of the motor. To learn about the importance of weight distribution, see our guide on e-bike weight.
In terms of efficiency, hub motors may not perform as well as mid drive motors. While they can offer a pleasant and natural ride on flat roads, their performance may falter when climbing steep hills or carrying heavy loads. This is because hub motors operate independently of the bike’s gears, unlike mid drive motors that can leverage the bike’s gearing for improved torque and efficiency. Despite this, hub motors continue to be a popular choice due to their simplicity, affordability, and the natural feel of the ride they provide.

This can affect the overall ride quality, as well as the ability to take sharp turns and navigate tight spaces. Electric bikes with mid-drive motors tend to provide better traction, while hub motors can cause the bike to slide when cornering.
Gearing Systems
Mid-drive eBikes integrate the motor with the bike’s gears, optimizing power and efficiency. By adjusting gears based on terrain, the motor can maintain peak performance, enhancing power, torque, and battery usage. This is particularly effective for steep hill climbs and achieving high speeds on flat or downhill routes.
Hub motors, however, operate independently, leading to less efficient energy use, especially during uphill rides or at high speeds. Unlike mid-drive motors, small hub motors might struggle with steep ascents.
Mid-drives are compatible with low-maintenance internal gear hubs and belt drives, an advantage in stop-and-go urban or hilly rides. Remember not to shift mid-drives under power to prevent chain damage; most modern models auto-cut power during shifts.
Climbing Ability
Climbing hills can be a challenge with any ebike, but the ability to do so is greatly impacted by the gearing system you choose.
Mid drive motors work by having the motor system directly connected to the chainring, providing greater torque when you need it most. This torque is what helps propel you up hills with ease.
While a hub drive motor is located at the rear (or front) wheel, and doesn’t directly interact with the chainring. This makes it much harder to climb hills since the motor isn’t providing additional torque. The hub drive system still makes it a popular choice for those who don’t need to climb steep hills.
Motor Size, Weight, and Performance
Understanding the impact of size and weight on your e-bike’s performance can be instrumental when you’re on the verge of making a crucial choice between a mid-drive motor e-bike and a hub motor electric bike.
