When considering purchasing an electric bicycle, the electric bike motor is a crucial factor as it determines your riding experience, including speed, power, and battery life. In this guide, we will delve into different types of electric bike motors, torque, power, and how to make the best selection. Whether you are a city commuter, fitness enthusiast, or leisure cyclist, understanding electric bike motors will help you make right purchasing decisions.

Which type of motor is commonly found in electric bikes?

The type of motor installed in electric bikes varies based on the brand or manufacturer of each particular model. As an illustration, BUYMOREWAY's electric bike range features different motors, including rear and mid-drive motors sourced from various manufacturers like Bafang, Ananda. Mid-drive motors, such as those found on our Fafrees models, offer enhanced power capabilities and are particularly well-suited for scaling extensive, steep inclines.

Which is better - hub motor or mid-drive motor?

When comparing hub motors and mid-drive motors, the better option usually depends on the type of electric bike you have and how you plan to use it. Hub motors require very little maintenance since they are sealed units, which makes them popular. However, they are generally more suitable for flat terrain because they operate with a single gear ratio.

Mid-drive motors, on the other hand, do not have a single gear ratio, making them better suited for regular hill climbing. They are also typically lighter than hub motors, which can be important if the overall weight of your electric bike is a concern. Additionally, mid-drive motors can be more discreetly placed, which might be preferable for aesthetic reasons. Changing a tire is also easier with a mid-drive motor since you don’t have to manage the weight of a motor attached to the wheel.

In conclusion, when choosing between a hub motor and a mid-drive motor, the best option depends entirely on how you plan to use your electric bike.

How long do e-bike hub motors last?

Typically, an e-bike hub motor can last around 10,000 miles, provided it is well-maintained. The most susceptible part of your hub motor to wear and tear is the bearings (assuming it’s not a brushless motor). Aside from potential rust, which can be minimized by storing the bike indoors, your electric bike hub motor can have a very long lifespan.

What is torque in e-bike motors?

Torque is the measure of rotational force in an e-bike motor, determining how swiftly it can deliver power. For e-bikes, torque is expressed in Newton-meters (Nm). In short, the higher the Nm your e-bike motor generates, the easier it will be to pedal.

Across our range of electric bikes you'll find a range of torque options. For example, the Fafrees F20 Pro and LANKELEISI ES500PRO operates at 40Nm, the DUOTTS C29 and Fafrees F20 X-Max have 65Nm, and the Fafrees F26 CarbonX offers 95Nm for easy pedaling and a smooth riding experience.

What is the optimal power rating for an e-bike engine?

The ideal electric bike engine power depends on the specific bike that is intended to power. For instance, the SAMEBIKE 's 20LVXD30-II motor is rated at 250 watts, which is ideal for a compact folding bike. On the other hand, larger model like the LANKELEISI RV800 Plus is equipped with Bafang e motor that can go up to 750 watts.

Are e-bike motors AC or DC?

Electric bike motors typically operate on direct current (DC). This is because of their straightforward design and widespread availability.

Do electric bikes use brushless motors?

Many contemporary electric bikes utilize brushless motors, which also known as BLDC motors. These electric motors for bicycle operate without brushes to regulate electric current flow, eliminating a component prone to wear and potentially extending the motor's lifespan.

What are the disadvantages of a BLDC motor?

The primary drawback of a BLDC motor is its higher price. These e-motors for bicycle are more intricate than standard models, leading to a correspondingly higher cost. Nonetheless, as previously noted, their reduced wear compared to brushed motors offers added assurance, making the investment worthwhile in our opinion.

Is a 250W motor enough for an electric bike?

Absolutely, a 250W motor is sufficient for an electric bike — it happens to be the highest permissible limit for e-bikes in the UK. Several of our electric bikes utilize 250W motors, which are ideal for both casual outings and more adventurous journeys!

Is e-bike motor weight important?

If you desire an extremely lightweight e-bike, then yes, motor weight does matter. The most lightweight motor systems can be 2-3kg lighter than the heaviest ones. This difference can be even more significant when comparing models with large battery capacities to those with smaller ones.

Small electric bike hub motors typically weigh approximately 1.5kg, whereas mid-drive motors tend to weigh about twice as much.

Do Bosch e-bike motors need servicing?

Just like any other component of your e-bike, Bosch e-bike motors require regular servicing. For Bosch electric bikes, Bosch advises an initial inspection after 4 weeks (or 300 miles), followed by routine checks at subsequent intervals.

If you have any other alternatives like Bafang electric motors, the same principle applies.

How do I choose an electric engine for bicycle?

Selecting an electric engine for bicycle doesn't have to be complex. In fact, all our electric bikes feature motors designed to provide everything you need (and more) from your ride. For example, our mid-drive Motor E-Bike Fafrees FM8 uses a simple quick stop ANANDA M60 motor, while the ENGWE P275 PRO uses an advanced 250W Bafang electric motor. Both motors are perfectly suited to their bikes - that’s one less thing to worry about!
