Portable Electric Bike: From Riding to Easy Storage

Often a portable electric bike is sold as a foldable bike.

While folding may be an important step, it just helps with one piece of the road. But the rider might still have to get the bike in or out of the car, maneuver it through a station, get it in or out of an elevator, move it around an office or put it in a closet without blocking a hallway.

Hence, portability is a series of true portability:

Stop, Fold, Move, Store, Unfold and Ride

The bike might end up spending more time at home than on the road if the one-step is not convenient.

Zoulaglide has created a few different folding formats in their Electric Bike Buyer's Guide for use in an urban setting, for short distances, the elevator, the car trunk or for limited space indoors.

 

Transfer Points are the first step towards portability.

Most buyers start by comparing the motor output, range or total weight of the machine. The better idea is to chart all of the transitions in the typical path.

For example:

lapartment to elevator;

lelevator leading to building entrance;

lStreet to Platform;

lstation entrance to carriage;

lparking space to boot of a car;

lOffice to storage corner;

lFrom the campsite to the storage compartment of an RV.

Different constraints are formed with each transfer. Stairs add the elements of raising weight and safe handrails. Train travel is about collapsed dimensions and agility. The key factors for car transport are the opening size of the trunk, the height to which the bike can be loaded and whether the folded bike can be left upright or not.

The best portable electric bike is the one which will go through the most difficult place without it resulting in some other issue.

Transfer Point	Space Constraint	Movement Required	Key Measurement
Apartment Stairway	Narrow turns and limited landing space	Carry	Stair width and carry distance
Elevator	Door and cabin dimensions	Push or stand	Door width and floor area
Train or Subway	Crowded entrances and luggage rules	Fold and wheel	Folded width and height
Car Trunk	Restricted opening and loading height	Lift	Opening size and trunk depth
Office Storage	Limited floor clearance	Fold and park	Available storage footprint
RV or Boat	Irregular compartment shape	Lift and secure	Opening and internal dimensions

 

The term “foldable” means a lot more when you consider how dimensions will change.

One electric bike folds up and another doesn't, and they both have different size folds.

There are some models that fold only at the frame. Some of them also bend the handlebar, stem or pedals. Overall, a second folding point can be used to decrease the width or the height of the bike, which will make it easier to fit underneath a desk or in a vehicle.

Prior to choosing a bike, measure:

lthe width and height of the trunk of the car;

lspace in the house to move around;

lwidth of elevator and doorway;

lThe clearance under a desk or storage-shelf;

lovercome any restrictions on public transport size.

Check against the "overall" or folded length, width and height, not just the wheel size.

Zoulaglide's S7 urban folding design features a four-step double-folding system, and has folded dimensions of about 27 × 17 × 22 inches. It is designed for trunk travel, office storage, elevator, and urban multi-modal travel.

 

In order to be a good folding mechanism it should be repeatable.

The folding system must be fast, easy, and unambiguous and should have a positive locking mechanism, which prevents accidently folding the system in the wrong direction.

Important details include:

lthe number of folding steps and the order of the steps;

lIf tools are needed;

llatch position and locking feedback;

lSafeguard against unintentional access;

lMovement of cable around hinge:

lwhether components come in touch with the ground;

lWhen folded, it provides stability to the bike.

There should be more to quality than just speed. If the bike takes more than a few seconds to fold up, or if the bike is unstable on the ground when folded, it could be unwieldy at actual transfers.

Riders should take the time to practise a number of fold and unfold drills in a safe place. Before each ride, check all latches to make sure they are closed and the handlebar, saddle and pedals are right.

Portable does not necessarily imply "carryable.

There are some portable electric bikes which are built to be lifted. Some are more convenient to wheel, push or partially fold.

When the bike has to go up and down stairs or through a small entrance or a full station, it gets more difficult to carry the bike. In such cases it's not only about the overall weight. The shape of the folded bike and weight distribution are key factors to the bike's ability to be close to the body.

Practical carry test should take account of:

lthe location of the center of gravity;

laccessible frame handholds;

lpedals or handle bars that stick out;

lExposure to chain and brake-disc;

lDistance from the storage area to the riding point;

lhow long the bike is to be off the ground for.

A slightly heavier bike that will roll easily when folded may be more useful if there are no stairs involved in the route.

 

Changes to the Transfer Routine are due to Battery Design.

Use a removable battery to lessen the amount of weight to lift and to charge the battery separately to the bicycle. But taking it away introduces another object which needs to be carried and protected.

An integrated battery is a cleaner, in-bike package, but also maintains the total bike weight when carrying the battery. There is no simple universal answer to which of these is best.

A removable system would be a good choice for riders who:

lreside in the upper layers of the soil;

lAre not able to charge close to the storage area;

lwant to store the bike in a car when charging inside;

llike to lose weight prior to lifting.

For those who value an effortless folding and storing process and want fewer individual parts, an integrated system could be perfect.

It is important that the battery terminals are dry and protected, and only used as a lifting handle if specified by the manufacturer.

The Ride should not be compromised by portability!

Even when folded a compact bike should be easy to control when extended.

Compact stored package and responsive urban handling may be achieved with small wheels which may be more sensitive to potholes or edges of surfaces. Bigger tyres allows more comfort and stability, but will also add to the folded width and rolling resistance.

During normal riding, the folding frame also should be rigid. The rider should look for freeplay between the hinge, handlebar stem, saddle post and pedal connections.

As with portability, braking, tire condition, lighting and rider position should be given equal consideration. The Zoulaglide S5 foldable electric bike features fat tires, disc brakes, pedal assist and can handle all types of urban terrain.

 

Solve Different Portability Problems in S5 and S7.

The S5 is ideal for those who would like a foldable bike capable of navigating between city roads and some rougher terrain. It offers the convenience of storage space with its compact design and the safety of ride stability and mixed road capability with its wider tires.

The S7 is more specifically geared towards densified urban transfers. It has a double-fold design that minimizes the saved footprint of offices, apartments, trunks and public transport connections.

The decision shall be made in line with the journey:

lIf you have to drive on different types of road surfaces, then you should get a wider-tire folding option;

lSelect smaller double-fold package for indoor storage, frequent handling;

lIf portability and shopping or family chores need to go hand in hand, then take into consideration cargo-equipped compact models.

Zoulaglide's smart mobility collection is another example to use as a reference when designing models that need to be small and versatile for the flexible life in the city.

This is a test of the Entire Portable Routine

Even a brief test drive won't uncover all of the portability problems.

 

This should involve folding up the bike, getting it through a door, setting it up in where it will be stored, unfolding it and testing all the locks and riding it back up.

If car transport is a priority, check to see if the bike will fit in the car without the trunk lid being forced or weight placed on sensitive parts of the bike. Do not store the bicycle near damp areas, heaters or emergency exits, during indoor storage.

When it comes to portable electric bikes, the smallest to fold isn't necessarily the best. It is the model that allows it to be repeatable, thus becoming part of the rider's normal day.

FAQ

Q1. So, what makes an electric bike portable?

Portable electric bike is a combination of compact size and convenient foldable/portable mechanism. As important as the weight are the weight distribution, carrying points, battery design and folded stability.

Q2. Is a portable electric bike going to fit in the rear of a car?

Many compact folding models can, but the trunk opening and size varies. Measure the full folded sizes compared with the trunk's narrowest part before purchase.

Q3. Can I ride my e-bike on public transportation?

Rules are different for each operator, route and time of day. Before planning regular mixed-mode commute, check with the folded-size, battery restrictions, luggage and peak hour restrictions.

Q4. Does a removable battery make for portability?

It may help lessen lifting weight, and make charging easier inside. It however forms another component which needs to be carried, stored and guarded en route.

Q5. Do small wheels make for an unpleasant driving experience on bad roads?

While small wheels are likely to be more sensitive to surface irregularities, other factors such as width, pressure, suspension and speed influence comfort. Select the appropriate wheel and tire configuration, depending on the real track.
