Electric Bike Mid Motor

Presentation of electric bikes with mid-drive motor

An electric bike with a mid-drive motor is an electric-assist bike whose motor is located at the crankset, in the center of the frame. This configuration allows for intelligent and smooth assistance, adapting to the pressure applied on the pedals. The motor uses the bike's transmission to provide support that adjusts to the terrain, whether climbing, on flat ground, or descending.
Crank motors are found on several types of electric bikes, whether on urban electric bikes, of the Electric VTCs or even electric mountain bikes

Why choose an electric bike with a mid-drive motor 

Choosing an electric bike with a mid-drive motor means opting for efficient and natural assistance. These comfortable electric bikes attract both casual walkers and regular cyclists for several reasons: 

#1 The natural assistance of electric bikes with crank motor

The central motor operates with a torque sensor that measures the pressure applied to the pedals. Result: progressive and responsive assistance that respects the cyclist's rhythm.

#2 A better weight distribution

By being positioned at the center of the bike, the motor contributes to optimal balance. This improves stability and control, especially in turns or on difficult terrain.

#3 Increased performance on climbs

Thanks to the use of the transmission, bikes with a mid-drive motor are particularly efficient on slopes, even with a moderate level of assistance.

#4 More autonomy and efficiency on your electric bike

The crank motor generally consumes less energy for an equivalent power, which helps to extend the battery life.

#5 Ideal for all types of trips

This type of engine is suitable for both urban use and for hiking, country roads, or hilly terrain.

How to make the right choice of electric bike with a mid-drive motor?

Choosing an electric bike with a mid-drive motor requires considering several essential criteria to ensure a good compromise. The first step is to clearly define your usage: do you want a bike for daily commutes, leisure rides, or long-distance sports outings? This question will guide your choice.
Then the type of motor plays an important role here. The crank motor, located at the bottom bracket, offers more natural and better dosed assistance, as it directly adapts to your pedaling effort. This type of motor is particularly recommended for more difficult terrains, as it optimizes traction and bike balance, while providing you with a better riding sensation.
The weight of the bike is also an important criterion, especially if you have to carry it or pedal without assistance on certain routes. A light electric bike with an aluminum or carbon frame will make the bike more enjoyable to handle, especially on climbs.
The battery life should be suited to your habits: for daily trips or long rides, choose a bike capable of covering between 60 and 120 km. Also, remember to check the charging time, especially if you use your bike regularly.
Finally, pay attention to the quality of the equipment: disc brakes, smooth transmission, tires suitable for the road, readable control screen... All these elements ensure a safe and enjoyable riding experience. 

How much does an electric bike with a mid-drive motor cost?

The price of an electric bike with a mid-drive motor depends on several factors: the motor power, torque (Nm), battery capacity, components (brakes, transmission, suspension), and of course the brand of the assistance system (Bosch, Shimano, Yamaha, etc.). Here is an estimate of the price ranges according to the level of the range:

•  Entry-level: between €2,000 and €2,500
  These models are generally equipped with a basic 250W mid-drive motor, with moderate torque (40 to 50 Nm) and a 400 to 500 Wh battery. Perfect for urban use or for flat trips with little load.

• Mid-range: between €2,500 and €3,500
  Here we find Bosch Active Line Plus, Shimano Steps, or Yamaha PWseries motors, with a torque of 50 to 70 Nm. The range can go from 70 to 100 km, ideal for mixed use (city, rides, small hills).

• High-end: from €3,500 up to €5,000 and more
  These models feature powerful and dynamic motors (Bosch Performance Line CX, Shimano EP8, etc.) offering 85 Nm or more, with batteries ranging from 625 to 750 Wh. They are designed for longer rides, challenging terrains, and intensive use, with high-end components (hydraulic brakes, 11-speed or more transmission…).

Expert tips for using electric bikes with mid-drive motors

To fully enjoy the performance of your electric bike with a mid-drive motor, some good habits should be adopted daily. Before each ride, check that the battery is fully charged and that the tires are inflated to the correct pressure. An underinflated tire increases rolling resistance and can significantly reduce the range.
Adopt a smooth and steady riding style, especially on climbs: the crank motor responds to your pedaling cadence, so the more gradual the effort, the more effective and natural the assistance will be. To optimize battery life, remember to adjust the assistance level: favor a light mode on flat terrain, and increase it only on hills or in strong wind.
Finally, to preserve the battery life and components, store your bike in a dry place, protected from moisture and extreme temperature variations. These simple steps will extend the performance and reliability of your bike in the long term.

Maintenance tips for Gravel electric bikes

Electric bikes with mid-drive motors are known for their robustness, but it is important to maintain them regularly to ensure their proper functioning and preserve their performance over the long term.

For bike maintenance, you can find our bike maintenance products to optimize the performance and lifespan of your electric bike, while ensuring your safety during your rides.

#1 Tire pressure of an electric bike with a mid-drive motor

The pressure must be between 1.8 and 2.3 bars on the original tires: check the pressure indication on the sidewall of your tire or inner tube. 

# 2 Lubrication of your electric bike's chain 

The chain lubrication must be done every two weeks with a silicone lubricant.
In case of rain, it is preferable to lubricate the chain every week.

#3 Checking the screws of your electric bike crank motor  

Regularly check the screws. Apply threadlocker to all screws that have moved.

#4 Derailleur Adjustment

Fine-tune the derailleur adjustment and ensure that the cable does not lose tension. Lubricate the cable every 6 months.

#5 Purge and brake pads

Check if a brake system bleed or a brake pad replacement is necessary.

Don't forget to have your bike serviced once you reach 500/1000Km!
