Introduction

Electric bikes that can fold up small are growing in popularity thanks to their blend of power-assisted riding and convenient storage. But how do folding e-bikes compare to regular electric bicycles when unfolded and in use?

This guide examines the key differences in ride handling, motors, batteries, frames and components. We reveal where folding e-bikes excel for real world urban mobility and where non-folders have the edge.

Key Differences Explained

Folding mechanisms introduce some inherent differences from regular bicycles:

Size When Folded

Folders shrink to a fraction of their riding size to typically 30-50cm wide x 60-100cm long x 30-80cm tall.
Non-folders remain full size – around 170cm long and 60cm tall.

Weight

Folding frames and parts add weight, typically 2-5kg over similar specced non-folders.
But lighter composite frames on some folders compensate for folding hardware.

Wheels

Smaller 16-20 inch wheels on folders versus standard 26” or 700c wheels on regular e-bikes.

Frame Materials

Folders often use steel or aluminum rather than carbon fiber which can crack at folds.

Suspension

Folding bikes benefit more from suspension to compensate for smaller wheels.

Power Systems

Folders favor mid-drive motors which don’t compromise frame strength.

Portability

Folders can be wheeled or carried when folded – a major advantage.

Unfolded Ride Comparison

When unfolded and in use, ride feel differences include:

Smaller wheels make folders slightly less stable and more twitchy handling.
Shorter wheelbase also impacts steering requiring more rider input.
Frame flex can be an issue if folded frame joints loosen over time.
More affected by bumps due to lack of tire volume and suspension travel.
Slower acceleration with smaller wheels and added weight – but electric assist compensates.
Traction reduced climbing hills due to less tire contact area.
Tighter turning circle suits nimble urban riding.

Advantages of Folding E-bikes

Key benefits that folding electric bikes enjoy over non-folding models include:

Compact folded size – Small storage footprint at home or work
Easy to transport – Can take on trains, buses, Ubers etc
Multimodal commuting – Fits public transport luggage allowances
Theft deterrent – Can be safely taken indoors unlike regular bikes
No parking hassles – Folds away out of the way in seconds
Charging flexibility – Batteries can be charged anywhere indoors
Air travel compatible – Can check as luggage or carry-on when flying

For urban living where space is limited, folding e-bikes are a highly practical mobility solution.

Disadvantages of Folders

Downsides associated with folding e-bikes compared to regular electric bicycles:

Higher cost – Complex folding hardware adds expense
Heavier – Folding mechanisms add weight, typically 2-5kg
More maintenance – Pivots and hinges require cleaning and lubrication
Reduced stability – Smaller wheels are less stable and twitchier steering
Rougher ride – Short wheelbase and limited suspension on small folders equals harsh ride
Lower load capacity – Weaker frames limit cargo compared to sturdy non-folders
Limited top speed – Smaller wheels have lower gearing ceilings constraining top speed

So comfort and carrying capacity are compromised, but improved portability is the payoff.

Buying Considerations

Factors to weigh up when choosing between folding and non-folding electric bicycles:

Storage space

Folders require less than half the space of full size bikes.

Usage

If multi-modal commuting dominates, a folder’s compact size when folded makes transit easy. For longer weekend rides, non-folders are more stable and comfortable.

Budget

Well designed folders demand higher engineering expense so cost more.

Terrain

Non-folders ride more smoothly over rough ground thanks to bigger tire volume and frame rigidity.

Carrying ability

Only folders offer the ability to haul them upstairs or onto vehicles when folded.

Theft deterrence

Because they can be stored securely indoors, folders are less prone to theft.

Frame and Component Differences

Folding e-bikes feature special designs to allow the frame and components to compress.

Frame

Hinges, pivots and telescoping sections enable the frame to fold.
Main hinge folds the rear triangle and front triangle together.
A secondary hinge halfway along the main tube creates a pull handle when folded.
Hinges introduce potential flex so high quality frames use stiff clamping locks when unfolded.

Wheels

Either both or just the rear wheel reduce in size, typically to 16 or 20 inches.
Quick release axles allow wheels to be removed to shrink the folded bundle.
Many models adopt magnets to hold wheels in place when folded.

Handlebars

Usually fold sideways and rotate parallel to the frame.
Telescoping adjustable height stems maintain fit but fold down lower.

Pedals

Tend to be smaller to avoid hitting the folded frame but compromising power transfer.
Can fold or rotate to hug the frame when folded.

Seat post

Reduces minimum insertion to allow the seat to lower when folded.
Quick release clamps enable fast height changes.

Cables

Feature extra housing length to accommodate folding and flexing.

Folding vs Non-Folding Electric Bike Pros and Cons

Ride Style Priorities

Choose your e-bike type based on your riding needs:

Multi-modal commuting – A folder’s compact size when folded makes public transport and ride shares simple.

Family transport – Larger non-folding models accommodate kids and haul shopping better.

Apartment living – Limited space makes folders a savvy choice.

Cycling for leisure – For comfortable distance riding, non-folding e-bikes provide stability.

Heavy loads – A non-folder’s stronger rigid frame handles big cargo better.

Occasional use – If cycling infrequently, a folder can be stowed out of the way.

combining transport types – folders enable mixing cycling with trains, buses and Ubers.

20″ Folders – The Best of Both Worlds

If your storage space can accommodate a slightly bigger folded size, mid-sized folders with 20 inch wheels strike a great compromise between folding down small and a comfortable, stable ride when unfolded.

While not micro-compact like Brompton 16 inch folders, quality 20 inch wheel folding e-bikes retain portability for multi-modal commuting or apartment living while providing a much more comfortable, assured ride similar to larger wheeled non-folding electric bikes.

The modestly bigger wheels roll over bumps and cracks easier while the wheelbase is long enough for relaxed steering control when riding.

Models to consider offering great foldability without major ride compromises include the GoCycle G4i, Swiftmile and Tern Vektron among others.

Making Folders More Comfortable

Some ways to improve ride comfort on folding e-bikes:

Quality suspension – Add front forks or even rear suspension to absorb bumps.
Volume tires – Wider tires cushion better than skinny ones.
Correct tire pressures – Run at maximum rated pressures for stability.
Upright position – Reduces weight on hands and improves control.
Gripper pedals – Feet stay planted when pedaling hard.
Mitigation accessories – Items like suspension seat posts and wider saddles.

Yes, folders sacrifice absolute comfort but these mods can still provide an enjoyable, stable ride.

Frequently Asked Questions

Can you take electric folding bikes on trains and buses?

Yes, their compact folded size conforms to most public transport luggage allowances. But always check carrier policies.

How much smaller do folding bikes fold?

Typically to around 30-50cm wide x 60-100cm long x 30-80cm tall – less than half their riding size.

Do folding bikes require more maintenance?

Yes, inspect and lubricate hinges, clamps and pivots more frequently as these are vulnerable points to dirt and wear.

Are folding e-bikes slower than regular e-bikes?

The small wheels limit absolute top speed but electric assist levels the playing field. For legal 25km/h cuts out, they can keep pace.

Can folding bikes carry much luggage?

No, maximum load limits are typically under 20kg. A rack helps but use panniers sparingly and don’t overload fragile frames.

Final Thoughts

Folding e-bikes introduce some ride compromises but unlock amazing practicality benefits for urban living and commuting. Clever hinge mechanisms allow them to shrink down small for space-saving storage and public transport use.

While non-folding e-bikes offer greater stability and load capacity, folders equip you for multi-modal mobility and compact home storage. Choose based on your riding priorities.

For many urban cyclists, the ability to fold an e-bike pays dividends in convenience that outweigh any handling or comfort tradeoffs while still providing powered assistance.
