Looking for a mid-drive ebike? Wondering what a mid-drive motor even is? We’ve got answers to help you decide what kind of ebike is right for you.
Are you a rider looking for an ebike with extra range, a more natural-feeling electric assist, and better handling? A mid-drive ebike may be the best solution for you. While they tend to be a bit pricy, electric bikes with mid-drive motors offer an improved experience and added performance, especially for mountain bikers, performance road cyclists, and cargo ebike users.
Mid-Drive vs. Hub-Drive
Before we get into the pros and cons of mid-drive ebikes, let’s look at the difference between mid-drive and hub-drive motors, which are the two main types of motors.
Mid-drive (also known as crank-drive) motors are integrated into the bottom bracket and crankset of the bike. They work synergistically with the pedaling torque of the rider to provide the most accurate power assist. Since the motor is connected to the rider’s pedaling, mid-drive motors only offer pedal assist and don’t provide throttle power (although there are some rare exceptions to this rule).
Hub motors are integrated into the wheel's front or rear hubs and are less expensive to produce. Most hub motors use cadence and speed sensors to calculate power assistance.
Rear hub motors tend to feel like they are pushing the bike, whereas front hubs will have a pulling sensation. Hub motors can provide pedal assist or stand-alone throttle power, where the rider doesn’t have to pedal for acceleration.
Torque is the measurement of the force that the motor applies to rotate the drive wheel of the bike. It’s measured in Newton-meters (Nm). Electric bike motor torque ranges from 30 to 105 Nm.
Extra torque is important if you are carrying heavy loads or riding steep hills. For example, if you are looking at a cargo ebike for hauling multiple kids or a whole load of groceries, you’ll want a motor with 65-105 Nm of torque.
Mountain biking is another area where torque is essential. It provides the necessary power to ride through steep, technical climbs.
Different mid-drive motors are designed for classes of ebikes.
For more information, refer to our guide on ebike classification.
Since most mid-drive motors are pedal assist, they mostly will fall into Class 1 or 3. Many mid-drive ebikes are Class 1, which is sufficient for the average rider’s needs. If you’d like to keep up with city traffic or just want to ride faster, Class 3 ebikes have a higher top-assisted speed of 28mph.
Pros of Mid-Drive Ebikes
Mid-drive ebikes typically have a greater range than their comparable hub-drive counterparts because the integration of the motor into the cranks allows it to run at more efficient RPMs. Mid-drives also utilize a torque sensor which optimizes the assistance to the rider’s effort.
More natural feel
The motor applies power directly to the pedal stroke and provides more natural assistance, matching the cadence and torque the rider applies. Mid-drive motors eliminate the jerky acceleration that is common with hub-drive motors.
Low center of gravity
The positioning of the motor next to the cranks places the heavy weight of the motor (6-8lbs) low and centered between the bike’s wheels. A low center of gravity improves the balance and maneuverability of the bike, which benefits all riders but is especially desirable for mountain bikers.
The controlled acceleration of a mid-drive motor is safer for the rider. Hub motors tend to deliver more vigorous bursts of power that can be jumpy and hard to control. A mid-drive motor delivers smoother, more predictable acceleration for the rider. This is particularly beneficial when riding on tight bike paths with other cyclists and pedestrians or mountain biking on a technical singletrack trail.
Easier to change a flat tire
Flat tires are one of the more common issues people have on rides. A hub motor requires extra tools and expertise to remove and replace the wheel when you have a flat. On a mid-drive ebike, the rear wheel is a conventional hub and derailleur system that is easier to repair on the road.
Cons of Mid-Drive Bikes
Mid-drive motors are more intricate than hub motors and therefore are more expensive. You can expect to pay $2,500-10,000 for a mid-drive ebike.
Mid-drive motors provide pedal-assist power only. If you are looking for a throttle option, you’ll need to look at hub motors (although there are some rare exceptions to this rule).
Mid-Drive Motor Brands
Here’s a list of the brands that build mid-drive motors. When buying an ebike, you can’t customize the motor, but you can choose the ebike that has the motor that fits your needs.
