Folding Electric Bikes: We review the best foldable e-bikes for 2021

January 20, 2021

People look at folding bikes and marvel at the new cycling invention that they are; what they don’t know is that folding bikes have been with us since the late stages of the 19th Century! They are the brainchild of Emmit G Latta; an American inventor who wanted to create an alternative transportation tool. According to one of the several patents he filed in 1887, he described his folding bike as a safe, sturdy, and serviceable machine that can easily be steered and requires minimal storage space.

"A folding bicycle is originally designed to fold into a compact form, facilitating transport and storage."

Folding E-Bikes Rising Popularity: Folding bikes have come a long way ever since their launch in the 1890s. The funny thing is that they were initially created for the military, owing to their convenience and overall efficiency. They were even used by paratroopers jumping out fighter planes in the Second World War; no kidding! Today, folding bikes continue to grow in popularity and application across the globe; from ordinary people with day jobs commuting to work to adventurers and campers looking to explore the open spaces. 

Go-to for the military: Before they became the revolutionary mode of public transportation that we see everywhere on the streets today, folding bikes were initially a reserve for the army. It started in the 1890s when the French Army took a keen interest in using folding bicycles for different military purposes. Soon after that, the British Army was the next to join the bandwagon and in 1900, Mikael Pedersen developed the first British folding bike. In the following years, multiple countries embraced the idea, and folding bikes became a mainstay in the barracks. 

Nowadays, folding bikes come in different designs for different purposes. People like them for their overall ease-of-use and practicality, which allows you to take them almost anywhere. Whether you are looking for a sleek and retro-inspired folding bike or something more contemporary with the latest innovative features, there is a model out there to suit your style and bring out your personality. 

Tired of commuting with your car? Over the last ten years, electric bikes have posed an intriguing alternative to those with short-medium distance commutes. Folding electric bikes add a few further benefits to the equation.

You can take them everywhere,

Plus, you don't have to fret about your bike getting stolen!

Ancheer Folding 250W

Ancheer Bike. The Best Folding Electric Bike of 2021

Ancheer has grown to become a dominant force in the E-biking industry.

While rivals like Gaint and Trek carved out their spot as the preferred manufacturers for big ticket ebikes (think $3000+ for the best e-bikes like the Trek Powefly 5+), they left a big hole in the budget e-biking market. 

Over the last 5 years, Ancheer as siezed this opportunity and once again came out with an affordable, high quality winner with their Folding Moutain Bike.

Full Review:

It sports a lightweight aluminum frame, shock absorbers on the front fork, as well as on the rear frame, and a 250 W motor which makes the bike street legal in both the US and EU.

The 36V 8AH battery will get you 15 miles (25 km) if you just let the engine do all the work, and around 30 miles (50 km) with full pedal assist.

As with any bike worth it salt, it comes with a Shimano pro transmission system.

Ancheer opted to go for the 21 speed system, which we considered to be overkill for an e-bike, but whatever, more gears never hurt nobody!

In the end, no matter which version you choose to get, you will get that feeling of superiority as you cruise up a hill with the wind in your hair, looking disdainfully at the poor regular bikers sweating it out. Plus you can laugh under your breath at the other e-bikers who paid $2000-$4000 when they could have gotten an Ancheer instead!

  • Battery: 48V, 14Ah (672Wh) with Samsung Cells
  • Range: ~40 Miles
  • Weight Capacity: 250 lbs.
  • Bike Weight: 68lbs
  • Charging Time: 4-5 hrs
  • Wheels: Kenda Krusade 20" x 4" with K-Shield Puncture Resistance
Sinch Foldable E-Bike

The Sinch is an exciting bike that can comfortably be used for both on-road and off-road adventurers, ensuring that you enjoy the best of both worlds. Its foldable design makes it easy for you during storage and allows you to throw it in the back of your trunk whenever you want to transport it. 

Thanks to a pair of chunky tires placed on this bike, the Sinch is an ideal choice for a rider with an insatiable affinity for adventure. Whether you want to ride on sand, gravel, rock, snow, or muddy terrains, the 20 x 4” wide Kenda tires are designed to plow the trail into submission. 

So, you can expect light work of the bumps and potholes you encounter on the road. The Sinch is held together by a 6061 double-butted folding aluminum frame, which you can collapse into a compact frame for convenient storage in the trunk of your car or under your desk. 

With the battery integrated into the frame, the bike spots an aesthetically sleek look that stands out of the crowd, especially with the black-and-white or all-black colors it comes in. To access the battery, you only need to fold the bike and simply slide it out. 

Between the high-rising flat handlebar with ergonomic grips and the wide seat with plenty of cushioning, you will have a comfortable time despite riding the bike for hours on end. The manufacturer also included an RST front suspension for an even smoother ride. 

However, the massive tires and a relatively bulky frame add substantial weight to the bike. At 68lbs, the last thing you want is to be stuck in the middle of the trail with an empty battery. On the bright side, the frame is strong enough to carry up to 250lbs of rider weight. 

This bike is fitted with a 500W rear hub motor that can push you to a top speed of 20mph on both throttle and pedal assist modes. The throttle and other controls are placed on the handlebar for easy access while a backlit LCD provides you with crucial ride data such as distance, speed, battery charge, etc. 

This bike is fitted with a 500W rear hub motor that can push you to a top speed of 20mph on both throttle and pedal assist modes. 

Also, the stopping power is provided by a pair of Tektro mechanical disk brakes. There are five different levels of pedal-assist to choose from, and this will depend on the kind of pace you prefer. Aventon Bikes paired the motor with a high-capacity 672Wh battery with Samsung cells to make sure you make the most of your fun outdoors. 

This pack can deliver an average riding range of 40 miles and will require between 4 and 5 hours to fully recharge when empty. Thankfully, a 48V 3Amp fast charger is included in the package to help you with this. 

On the downside, the chunky tires and bulky frame make this bike fairly weighty while the rear-hub motor shifts most of the weight to the back. This means you’ll have a hard time handling the bike on climbs, especially when you use it like a regular bike. Other than that, you can expect to make some fun memories with the Aventon Bikes Sinch!

Every component of this unit is designed to minimize the overall weight of the folding bike.

Is it worth getting a folding bike?

A folding bike is totally worth it! It is a practical transportation tool that you can use for your daily commute to avoid the morning traffic and chaos in the subway. This ensures that you get to work on time with your high spirits still intact. The collapsible design of the bike allows you to conveniently fold it into a compact size and carry it into the office building. 

If you stay closer to work and the road to the office is relatively flat, then a folding bike will be a useful acquisition in the ideal weather conditions. However, if you have to climb a long and hilly road to get to work and it rains heavily in your area, then you might want to reconsider getting a folding bike. 

 

Do folding bikes break easily?

All bikes have a breaking point; it applies to both regular and folding bikes. This will usually depend on the limit of the type of metallic material used on the bike’s frame. However, when you compare the two types of bikes, folding bikes indeed tend to break in half, and faster than their counterparts.

The explanation is basic physics! Applying a joint on any object will weaken it, and this is exactly what you get on the collapsible frame of a folding bike. The presence of joints and hinges on the frame creates areas of weakness that will easily give in to persistent pressure. This is a common problem with most folding bikes, even those from reputable brands. 

Also, the welding required on these joints further weakens the metals; so, the more joints you have on a bike, the more points of weakness!

 

Are electric folding bikes durable?

The general belief is that folding bikes don’t last, and this is usually credited to the joints and hinges on its frames. However, manufacturers are working hard to ensure that this is not always true. High-quality folding bike frames are designed to last by employing sturdier frame materials with reinforced joints and hinges. 

The load on the hinges and joints is also reduced in the design, making for increased durability while preventing easy breaking of the frame. This is why you will find folding bikes that last longer than some of their regular counterparts. 

 

Is it hard to ride an electric folding bike?

Riding an electric bike is no different from riding a regular bike. The only difference is that e-folding bikes are significantly heavier than their ordinary peers. However, the fact that you get an electric motor to help you propel the bike simplifies the riding process.

If you know how to ride a bike, it gets even easier when you get on an electric bike. A lot of the pedaling effort is reduced, so you can shift most of your focus to the handling. The only problem comes when you run out of battery power in the middle of the trail. Here, riding an electric folding bike becomes a nightmare!

 

How do I choose a folding electric bike?

There are several things to consider when choosing a folding electric bike, but the major features to look at when you are out shopping include the range of the battery, they type of electric assist (whether pedal-assist or throttle), the type of folding e-bike, the quality of components, and the cost of the bike. 

Be sure to examine all the above features vis a vis the kind of riding experience you want from your bike to find a model that best suits you!

 

Are foldable e-bikes safe?

While there is always a certain level of risk with any kind of physical activity you engage in, riding a foldable e-bike is safer than many other modes of transportation. If you’re riding the bike on a public road, there is nothing to worry about as long as you abide by the laid-out traffic rules and road safety regulations. 

The biggest concern with electric bikes comes in the form of its battery, particularly lead and lithium-ion varieties. Shipping and disposing of these components require a great deal of care and caution.
