Here is a closer look at the different types of e-bike frames to help you pick the precise design suited to your lifestyle and daily needs.

Traditional Frame (Step-Over Frame)

The traditional step-over frame style is a classic and popular design that has been around for decades. It features a horizontal top tube. The geometry can be both – relaxed and aggressive.

In addition, the traditional frame style is an excellent choice for casual cyclists who want an effortless riding experience.

Traditional frames also allow riders to step over the bike without swinging their leg over the top tube.

Pros of step-over frame style:

  1. Excellent stability and durability.
  2. Comfortable riding experience.
  3. Versatile and suitable for a wide range of riding styles, including commuting, recreational riding, and off-road adventures.
  4. Better maneuverability in tight spaces or busy areas.

Cons of step-over frame style:

  1. Not so easy to mount and dismount.
  2. The high top tube of a step-over frame can pose a challenge for riders with shorter inseams.
  3. While the step-over frame design provides stability, it can be relatively less forgiving in terms of shock absorption.

Step-Through Frame

The step-through frame style has a low and sloping top tube that allows easier mounting and dismounting of the bicycle. Also, it is an ideal choice for older riders because they will not need to lift their legs over the high top tube when getting on and off the bike.

Rigid vs Hardtail vs Full-Suspension Frames

In addition to the various e-bike frame styles, it’s crucial to consider the suspension system that best suits your riding preferences and terrain.

rigid vs hardtail vs full-suspension bike frames

Rigid frames, as the name suggests, lack any suspension components, offering a straightforward and efficient ride. They are ideal for urban commuting or smooth paved surfaces, where suspension isn’t necessary.

On the other hand, hardtail frames feature a front suspension fork while maintaining a rigid rear end, striking a balance between efficiency and comfort. Hardtails excel on moderate off-road trails, providing improved control and absorbing small to medium bumps.

Full-suspension frames (aka softail), equipped with both front and rear suspension, offer the utmost comfort and control. They excel in demanding terrains, such as technical trails or downhill descents, as the suspension absorbs impacts and enhances traction. However, full-suspension frames tend to be heavier and require more maintenance compared to rigid or hardtail frames.

Evaluating your riding style, the type of trails you frequent, and the desired level of comfort will help you determine which suspension system, if any, is the right fit for your e-bike adventures.

Which e-Bike Frame Style is Right for You?

It is always important to consider the bike’s intended use because frames have varying features that make them more or less suited to different types of cycling. Nonetheless, you can narrow down the options by considering your geometry & riding position, functionality, and looks.


The style of frame you choose determines many aspects of its performance. A full suspension frame, for example, provides more cushioning than a hardtail design and can be the better option for maneuvering rougher terrain.

You can also consider frames with built-in racks or mudguards to add extra practicality to your bike.

Geometry and Ride Position

The frame’s geometry is another crucial factor to consider because it affects how the bike responds to your inputs.

As a rider, always consider frames with well-balanced angles – such as shorter head tubes for quicker steering response. On the other hand, bikes with long chainstays are perfect for stability when cornering ensuring predictable and reliable handling.

A frame with a slacker head angle and a longer top tube is the perfect choice for an aggressive trail riding position. However, a more relaxed geometry like those offered by comfort bikes or cruisers is the best choice if you prefer to sit upright on your bike.


When deciding which electric bike frame suits best for you, you also need to consider the appearance of the e-bike.

After all, it’s you that’s going to ride it, and it must be appealing to you. We would never recommend buying a practical bike that you don’t like the look of.

Different Frame Materials of E-Bikes

From lightweight aluminum alloys to reliable steel, different e-bike materials have their advantages and disadvantages.

Here are the most common types of materials for bike frames used today.


Aluminum is one of the most popular material choices, offering a lightweight yet reliable frame that can handle heavy loads.

This material is also highly corrosion-resistant and can mold into various shapes. Unfortunately, aluminum frames are not as strong as steel frames and may require more maintenance.


Steel frames offer superior strength and durability but can be heavier than aluminum. They are also corrosion-resistant in wet conditions and provide good shock absorption while riding.


Titanium offers a combination of light weight, strength, and durability but is mostly used in higher-end e-bikes.


Carbon fiber is another popular frame material choice because of its lightweight and stiffness. Unfortunately, it can be expensive compared to other materials.

How to Choose E-Bike Frame Material?

When choosing an e-bike frame material, it is essential to consider the budget, intended use, and weight.


Aluminum is one of the most cost-effective materials for e-bikes. It is lightweight and sturdy for road bikes or mountain bikes.

Steel frames are relatively affordable but heavier than aluminum frames. Titanium frames offer superior performance and durability for more expensive models.

What Size Electric Bike Should I Get?

Here are our thoughts on how to choose the correct size bike frame.

Check Manufacturer Guides and Charts

Choosing the right electric bike size will guarantee the best ride experience. Moreover, each manufacturer has a size chart to help you make the best selection.

So, it’s best to read through the manufacturer’s guide and check their accompanying charts before purchasing. The most important measurements include height, standover height, leg length, and reach.

Height – Measure from the ground to the top of your head while standing with both feet flat on the floor to help determine which frame size fits your body.

Standover Height – This measurement is taken from the ground up to identify the clearance between your legs and the top tube. You should have at least an inch of standover height to guarantee a comfortable ride.

Leg Length – While wearing shoes, measure from your crotch to the floor to determine frame size.

Reach – This is the distance you can comfortably stretch out on the handlebars when seated in the riding position. You need to ensure that your reach is not short nor too long, as either can cause strain on specific muscle groups during longer rides.

Each manufacturer will also provide a chart, which can help you cross-reference different sizes by weight and leg length to understand what bike size you should get.

What to Do if You are in Between Two Frame Sizes?

Always remember an incorrectly sized frame can cause discomfort and poor performance on the bike. So, make sure to research and identify the correct size.

It’s best to consult a bike fitter if you are undecided about which frame size fits you. A bike fitter will measure you and your riding style to help determine the ideal frame size for your body type and riding style.

If that isn’t possible, look at the sizing guides provided by each e-bike manufacturer because the sizing charts with recommended rider height ranges correspond to different frame sizes. This can give you an idea of what size is right for you.

Finally, you can also test ride several e-bikes in both sizes that fit within your range of measurements before purchasing. It’s necessary to know how each bike feels and handles before making the final decision. Luckily, many bike shops and e-bike retailers offer demo rides, allowing you to have a better idea of which size best fits your body type and riding style.

Additionally, considering suspension options, such as rigid, hardtail, or full-suspension frames, can further enhance your riding experience based on the type of terrain you intend to conquer.
