We hear it all the time: “Mid-drive motors are better than hub motors for electric mountain bikes”. Most people stop there, but I feel as though it’s my responsibility as a bike nerd to explain why that is the case. 

There are big benefits to handling, hill climbing, ride feel, and efficiency when you opt for a mid-drive motor, though riders on calmer, paved terrain can run hub motors without feeling like they’re missing out. For steep hills and trail riding, however, mid-drive motors are the right choice for electric mountain bikes.

Hub motors vs. mid-drive motors: What’s really the difference?

Pretty much all electric mountain bikes rated for real trail riding are outfitted with mid-drive motors. And there are a few reasons for this, as I’ll explain below. 

Mid-drive units are head and shoulders above their hub-drive counterparts when it comes to steep, technical riding, but I’m not here to throw shade on hub motors either. Bike nerds love to split hairs and say motor types are wildly different in feel, but on calm terrain, the difference in feel and performance for recreational riders is not so big. But I’m feeling like giving a haircut, so let's slice through the advantages of mid-drive motors on e-MTBs!

Benefits of mid-drive motors on electric mountain bikes

Better weight distribution and handling

Mid-drive motors are positioned between the pedals at the center of the bike and low in the frame. This largely preserves the natural center of mass of the bike, and even though the motor adds weight, it doesn’t affect the electric bike's weight distribution as much as a hub motor inside the rear wheel. This more balanced design provides better handling, especially useful for tricky and technical terrain. 

A mid-drive motor also reduces the amount of unsprung mass on full-suspension electric mountain bikes. Unsprung mass is the weight of bike parts directly connected to the wheels— rather than the frame and rear shock itself— that moves when going over bumps and uneven terrain. Extra mass on the rear wheel— such as a hub motor— reduces the suspension’s performance and can decrease traction. A mid-drive motor avoids this problem altogether.

Superior torque and climbing hills

Mid-drive motors also typically have more torque and, more importantly, can leverage that torque to better climb steep gradients. Mid-drive motors use the mechanical advantage of the bike’s gearing system to deliver full torque levels at low speeds, maintaining a high (i.e., efficient) motor RPM even when the wheels are moving slowly, such as during a gruelingly steep climb. 

Mountain biking, unlike other types of riding, often involves some pretty crazy climbs, ones that are much steeper than typical hills that city e-Bikes or hub-drive electric bikes are designed for. The torque levels and connection to the bike’s drivetrain allow mid-drive motors to excel on the toughest slopes without straining. 

More natural pedaling feel

Another advantage of mid-drive e-Bikes is their natural-feeling pedal assistance. Most mid-drive motors use a torque sensor to determine how much power to release, responding proportionally to your own pedaling force. This method feels more responsive than cadence sensors, which only measure how fast you are pedaling.

Mid-drive motors deliver power directly to the electric mountain bike’s drivetrain, which is the same spot you put the power down when pedaling. The result is a more natural boost that feels more like an amplification of your own pedal power rather than an external push. Rear hub motors can seem like a push from behind, whereas front hub motors can give the impression of being pulled along— both fun sensations, but perhaps not what you’re looking for out on the trail.

Higher efficiency

Mid-drive motors also reign supreme when it comes to overall efficiency, especially when the route points uphill. Better motor efficiency means less power drain from the battery, extending your e-Bike’s range. Studies have found similar efficiency levels on flat or moderate terrain, though mid-drives are much more efficient on very steep hills. 

Mid-drive motors are much better at staying within their optimal rpm range thanks to the bike’s gearing. This limits motor strain and overheating. Mid-drive units are also typically better at cooling, while hub motors have little opportunity or heat sink spots to dissipate heat. Hub-drive motors, on the other hand, have one “sweet spot” when it comes to rpm.

Frequently Asked Questions

How much should you spend on an electric mountain bike?

Between $2,500 and $3,000 hits the sweet spot for entry- to mid-tier electric mountain bikes. That price range opens up the range of e-MTBs from top brands like Trek, Giant, Specialized, and others with innovative designs and quality parts. Models that fall into that price range are typically hardtail mountain e-bikes or pre-owned full-suspension models.

Spending less than $2,000 means the e-bike will likely come with a rear hub motor, less premium mid-drive unit, or an external battery. Riders can browse the best mountain bikes for under $2,000 designed for recreational riding and lighter mountain biking.

Where can I find trails that allow electric mountain bikes?

Apps such as Trailforks have an e-MTB filter to find routes that allow electric mountain bikes. E-Bike owners can filter the Trailforks map on the website or app to show trails where e-MTBs are permitted.  

Key Takeaways


  1. Better handling: Mid-drive motors offer balanced weight distribution and improved suspension performance for technical terrain.
  2. Climbing power: They deliver more usable torque by working with your bike’s gears, perfect for steep and challenging trails.
  3. Natural feel & efficiency: Torque-based assistance and drivetrain integration make pedaling feel intuitive and extend your ride range.
