Electric Bike

Our electric bikes come in three different styles, each of these have their own benefits and have been chosen specifically for the design and needs of each electric bike.

What motor is used in electric bikes?

The motor used in electric bikes will vary depending on the brand/manufacturer of a specific model. For example, the Raleigh electric bike range uses a variety of motors including rear and centre-mount motors from a range of manufacturers such as Bosch, Suntour, TranzX and Ebikemotion. Centre mount motors such as those on our Motus and Centros range provide a greater level of power and are perfect for climbing long, steep hills.

The Raleigh electric range incorporates motors from a number of manufacturers, depending on the needs and requirements of the rider and bike model. The Bosch system uses cutting-edge components to create precise motor control and lower noise output than other motors. Suntour motor systems are used in the Raleigh Array range to create an affordable mid-drive motor system that provides 3 power levels. The Stow-E-Way Raleigh folding electric bike uses a TranzX motor system as it is a compact and simple solution to be used on the go - perfect when combined with the storability and convenience of the folding bike.

What is torque in e-bike motors?

Torque is a measure of an e-bike’s rotational force, which essentially dictates how quickly it can deliver power. For e-bikes, torque is measured in Newton-metres (Nm). In basic terms, the more Nm your e-bike motor produces, the easier it will be to pedal. 

Across our range of Raleigh electric bikes you’ll find a range of torque options. For example, the Motus Tour operates at 40Nm, the Centros has 65Nm, and the Stride 2 (an electric cargo bike) offers 85Nm for easy pedalling with a load.  

What size motor is best for an electric bike?

The best size of motor for an electric bike will always be determined by the bike that it is designed to help power. For example, the Stow-E-Way TranzX motor we’ve mentioned above is 250w - that’s perfect for a smaller folding bike. For something bigger like a Motus or Centros, we use a Bosch motor which can range from 400-625w.

How long do e-bike hub motors last?

In general, an e-bike hub motor should last roughly 10,000 miles. That does assume that you’re taking care of your hub motor properly though. The most wearable component of your hub motor will be the bearings (assuming you’re not using a brushless motor). Aside from rusting, the risk of which you can minimise by storing your bike inside, your hub motor could last a very long time. 

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

When it comes to hub motor vs mid-drive motor, ‘better’ is usually down to the type of electric bike you have and how you’re using it. Hub motors are super low maintenance - they’re just a sealed unit so there’s less for you to worry about; it’s the reason that they’re so popular. However, they’re typically more suited to flatter riding as they only allow a single gear ratio. 

Mid-drive motors, on the other hand, don’t have a single gear ratio. This makes them better suited for tackling hillier routes on a regular basis. You’ll also typically find that they’re lighter than hub motors which can be important if you’re worried about the overall weight of your electric bike. If you’re also concerned about looks, the mid-drive motor has you covered - they can be a bit more discreetly placed than a hub motor. Oh and if you ever need to change a tyre, you don’t have to worry about dealing with the weight of a motor attached to a wheel. 

In summary, when deciding between a hub motor or a mid-drive motor, the best choice is entirely up to what you intend to use your electric bike for.

Are e-bike motors AC or DC?

Electric bike motors are usually DC. This is down to the simplicity of their design and how readily available they are. 

Are e-bike motors geared or gearless?

With Raleigh e-bikes, hub motor models are gearless. E-bikes with derailleur and cassette components are attached and geared. 

Do electric bikes use brushless motors?

A lot of modern electric bikes use brushless motors (also known as BLDC motors). BLDC motors don’t use brushes to control the flow of electric currents to the motor. Brushes are one of the components of a motor that can wear over time, so removing them reduces the risk of wear on your motor and can prolong its lifecycle. 

What are the disadvantages of a BLDC motor?

The main disadvantage of a BLDC motor is cost. They’re more complex than your average motor and the price tag reflects that. However as we’ve mentioned above, they tend to wear less quickly than motors with brushes which gives you a bit more peace of mind. If you ask us, that’s worth the extra cost!

Is a 250W motor enough for an electric bike?

Yes, a 250W motor is definitely enough for an electric bike - it also happens to be the maximum that you can have on your e-bike here in the UK. Many of our electric bikes (such as the Motus and Centros) use 250W motors and they’re perfect for both leisurely and more adventurous rides!

How do I choose an e-bike motor?

Choosing an e-bike motor doesn’t need to be complicated. In fact, you’ll find that all of our electric bikes come with motors that help you to get all you need (and more) out of your bike. For example, our Stow-E-Way folding electric bike uses a simple TranzX quick stop motor, while the Centros uses an advanced 250W Bosch Performance Line motor. Both motors are perfectly suited to their bikes - that’s one less thing to worry about!

Do Bosch e-bike motors need servicing?

Like any other part of your e-bike, your motor needs to be serviced. For Raleigh Bosch electric bikes, Bosch recommends that an initial inspection of your bike is conducted after 4 weeks (or 300 miles) and then at regular intervals after that.
