4 Best Lightweight Electric Bikes in 2019 | Reviews and Ratings of the Lightest eBikes

One of the challenges for developers of electric bikes is lowering their weight. The motor, battery and other additional features required to power an e-bike mean that they often end up considerably more cumbersome than a normal bike. 

There should also be a balance between being light and providing the rigidity and stability that comes with a smooth, safe ride.

E-bikes have come a long way in recent years in terms of their technical specifications. There are now several very lightweight models on the market that don’t cost the earth. We expect these weights to continue dropping as the technology advances.

We have pulled together some suggestions of the best lightweight electric bikes in terms of their weight when considered alongside their other specifications.

Why Lightweight eBikes Are so Important

A typical non-electric bike tends to weigh anywhere from 25 to 35lbs (11 to 16kg). Of course, this varies depending on budget, design, specification, and whether it is a road or mountain bike.

Electric bikes typically weigh over 40 lbs (18kgs), so they are considerably more substantial.

The biggest reason that serious cyclists opt for a lighter bike is that it can impact speed. This is particularly true when you are on ascents. The heavier the bike, the more you will have to work to get it up the hill, and the same is true for the work the motor will have to do.

If the bike is lighter, it also means that the mileage range that the battery life will cover should be more.

Of course, the lighter the bike is, the easier things become in terms of maneuverability and portability. Lifting a bike that weighs a few kilos more over a gate or wall can seem like a big difference when you are physically exhausted. 

It also makes a difference if you are a commuter having to lift your bike on and off public transport, for loading onto a bike rack, and for carrying upstairs to your apartment! 

Folding electric bikes, along with electric scooters, are becoming increasingly popular, and many designers compete to achieve the lowest weight possible.

Weight isn’t Everything When it Comes to an e-bike Though

While we are looking at lighter bikes in this article, it shouldn’t be your main focus when considering which e-bike to select. You should also be looking at things like the suspension, brakes, tires, motor and battery. 

If your bike is super light, but it doesn’t have an efficient motor and battery, it wouldn’t be a worthwhile investment.

It also depends on what you are using your bike for too. E-Mountain bikes are generally heavier than road bikes as they need a more robust frame, additional stability and they often have more advanced suspension.

Some manufacturers, controversially, don’t even publish the weight of their bikes when listing the specifications as they argue it should not be a deciding factor.

Be Aware of the Electric Bike Classes

Don’t forget to check the Class of the electric bike you are considering too. The laws vary depending on the country you are in. Within the United States, there are even some states that don’t conform to the norm. In Europe, e-bikes are generally not allowed to go above 15mph on their power-assist modes.

Check out the People For Bikes website, which is a handy resource for gaining a better understanding of these sometimes nuanced regulations.

In general, though, they are broken down as follows within the United States:

Class 1 e-bikes

  • Max speed of 20mph
  • Pedal-assist motor only
  • In some areas, the motor can be no greater than 250w
  • Generally no restrictions on where they can be used in the US

Class 2 e-bikes

  • Max speed of 20mph 
  • Pedal-assist mode or thumb throttle function
  • Motor no greater than 750w

Class 3 e-bikes

  • Max speed 28mph (often referred to as speed pedelecs)
  • Pedal-assist function only
  • Motor no greater than 750w
  • There are restrictions in certain States on where these can be used – always check

Best Lightweight Electric Bikes Reviews

We have selected four different lightweight electric bikes to review.

All of the bikes are under 45lbs (20kg).

Each has its own specific advantages in terms of features, usability and performance. Some of the key criteria we looked at when we were reviewing include:

  • Value for money – Even the best electric bikes can vary significantly in their pricing. Lightweight bikes are often more expensive. We look at a range of budgets and want to make sure that they are offering the best value for their price bracket
  • Motor efficiency – We compare the power, efficiency and level of smoothness of the motors.
  • Battery efficiency – We compare the batteries in terms of their efficiency, power and charging speeds
  • Overall performance – How do the bikes cope on the ascents and descents? What is the riding experience like, what is their suspension like? What is their weight capacity?
  • Reputation – How does the brand stack up against its competitors. Are they known for producing robust, high performing e-bikes?
EDITOR’S CHOICE

#1. Gocycle GS

Gocycle GS

Gocycle have been around for a while, and their aim has always been to build quality, lightweight urban bikes.

With a mid-range price point, you are treated to a whole host of high spec features and functional design and, for a folding option, this bike looks pretty slick too.

Specs

Type of BikeClass 2 (pedal-assist and throttle on demand)
Motor500w front wheel hub motor
BatteryLithium-ion battery, 13.5Ah, 22V, Approximately 300 Wh
Max Speed20 mph
Max Distance40 miles
BrakesHydraulic disk, front and rear
Charging Time7 hours
Drive TrainCleandrive® Shimano Nexus 3-speed
Weight36 lbs
Price$2,799

What We Loved

This bike has a powerful motor, battery and responsive hydraulic brakes. Compared to the less expensive eMazing Innovations design it will take you further, with a smoother, more comfortable ride.

Weighing in at just 36 lbs, this robust magnesium framed option is still pretty lightweight for a folding e-bike.

It is a very neat frame too, and all the electric components are stashed away tidily. A lot of people may not even realize it is an e-bike.

It only comes in one frame size, but it does have a very adjustable seat pole. Compared to the other folding bike we reviewed, it has a much more comfortable overall seating position.

It also has relatively fat tires and handlebars, a more balanced weight distribution, and rear suspension.

These all set it apart from many other folding e-bikes currently available.

The front and rear wheels are on a quick-release system, which makes it very easy to do any maintenance required.

Gocycle provides a lot of additional handy accessories. So, if you are making good use of your bike, some of these may be a good investment.

The portable docking station is perfect for you to give the battery a boost while you are at the office. Their bespoke front panniers will be great for transporting your lunch and any important paperwork.

If you want to avoid getting your newly laundered suit splashed on a wet day, you could even invest in their optional mudguards.

Why it Might Not Work For You

This bike can be a bit tricky to get the knack of folding down, and the motor is not the quietest of models.

The battery takes a yawn-inducing 7 hours for a single charge. Gocycle does offer an additional fast charger, but that obviously adds to your spending.

For a folding bike, this is at the top end of the market in terms of price. If you are on a minimal budget, the eMazing Innovation option could be a better choice.

Verdict

This bike is not as affordable as the eMazing Innovations one we review below, and it is not as light either (although it is still less than a kg of difference).

However, it has a much higher specification and more comfortable riding position. If you know you will be a regular bike commuter, this is a great investment.

BEST BUDGET LIGHTWEIGHT EBIKE

#2. e-Mazing Innovations BOB

This is a straightforward, no fuss, surprisingly lightweight folding e-bike.

It is a budget brand and model, so you shouldn’t be expecting a high specification or to do long distances or cover rough terrain.

This comes into its own as a simple and portable option for commuters. It often saves you having to chain your bike up outside, and this means there is less chance of them being damaged or stolen too.

It is easy to take onto public transport, and it will fit in the trunk of a car no problem. It can also be a good option for taking on a road trip or another holiday.

Because you often end up carrying a folding bike around more than a traditional frame, you do want this to be as light as possible. Given the price, this bike is amazingly light.

Specs

Type of BikeClass 2 – pedal-assist and throttle option
MotorFront Hub 250w
BatterySamsung Lithium-ion 36v, 324w
Max Speed20 mph
Max Distance20 miles
BrakesFront and Rear Mechanical Disc Brakes
Charging Time4-5 hours
Weight35 lbs
Price$1,299

What We Loved

Okay, so there are a few models out there that are lighter than this 35lb (15.8kg) model. But, at this price, it is unusual to find a half-decent folding e-bike that is anywhere close to this weight.

The frame folds down very quickly, and it is robust enough that it will not start to deteriorate with multiple fold downs. It is also smaller than a lot of folding e-bike frames, so it makes it even better for storage and maneuverability.

Being a Class 2 bike, it also has a throttle mode. Perfect to save you pedaling after a hard day in the office or for avoiding getting sweaty at the start of the day on steeper inclines.

Why it Might Not Work For You

This is just designed for straightforward, short distance riding. It is not going to cope with rough terrain or off-road trails, and it is not intended for long distances either. With a maximum range of around 20 miles per charge, it needs to be for short commutes.

It is only designed to hold up to 220lbs (99kg) in weight too, so it is not suited to larger riders.

If you are a speed demon, don’t opt for this bike. It can get a little unstable at high speeds, and it is not designed with adrenaline junkies in mind. It claims to go up to 20mph but, at this speed, it would be a bit of a hairy ride.

It can be difficult to source parts for this bike because it is not from a large, well-established e-bike dealer or manufacturer.

Verdict

While this is by no means a high-end model, it is functional if not pushed passed its limits. Given it has such an economical price and is a very lightweight for a folding e-bike, you can’t really grumble.

Perfect for short, simple commutes.

BEST FOR SPEED AND DISTANCE ON THE ROAD

#3. Trek Domaine +

Trek Domaine Plus

Trek is a well-respected and well-established developer of bikes. Their range of e-bikes is ever-growing too, and the Domane+ is one of their newest additions.

Endurance road bikes are not as commonplace on the e-bike market (the focus is on commuter and mountain bike varieties), but the Domane+ has quickly developed a fantastic reputation.

It is based on the design of their existing traditional Domane road bike and is surprisingly lightweight and slick. This is a very high-end specification that is aimed at the serious long-distance riders.

Specs

Type of BikeClass 3, speed pedelec
MotorBosch Performance Speed, 350 watt
BatteryBosch PowerTube 500wh
Max Speed28 mph
Max Distance70 miles
BrakesSRAM Force flat mount hydraulic disc brakes
Charging Time4.5 hours
Drive Train1×11 SRAM Force 1 drivetrain
Weight38 lbs
Price$6,999

What We Loved

Everything about this e-bike screams high end. It has a pretty mighty 350w bosch electric motor, perfect for reaching top speeds smoothly and swiftly. 

While this is primarily a road bike, it still manages on slightly rougher terrain well, and this makes it a pretty versatile option. It features an IsoSpeed decoupler in the seat pole, developed exclusively for Trek. This helps to absorb any bumps and can make things much more comfortable, especially on long haul cycles.

It also has gravel-orientated top-end Schwalbe tires which give it more grip on rougher terrain too.

Available in five sizes, it means you can get a comfortable fit – great for those longer rides. It is also ideal for taller riders who can often struggle to get into a comfortable position on one size only models.

There are not many decent electric road bikes out there at the moment and certainly not at such a lightweight. The Domane + tips the scales at just 37.89 lbs (17.19kg).

Trek has a reputation for providing excellent after-sales support, and offer a strong warranty.

Why it Might Not Work For You

It can go for around 70 miles in eco mode, but if you are continually using turbo, then it will not offer such distances. If you want to rack up the miles, it would be better not to hammer it speed wise and only use pedal-assist when you really need it.

It is expensive. There is no getting away from the fact that at nearly $7,000 this is only a bike for those that know they will get plenty of use out of it. It would be fair to say; this is not the best option for someone just starting on their cycling adventures.

If you enjoy off-roading, don’t opt for the Domane+. While it can handle gravel relatively well, it is not designed for rugged terrain, and this would likely damage your costly bike. Check out our reviews of some great electric mountain bikes instead.

Verdict

For long-distance endurance road bikers that are looking for an extra boost, this top of the range and very lightweight e-bike could be a perfect choice. Just get ready for a severe depletion of your bank balance.

BEST LIGHTWEIGHT E-MTB

#4. BESV TRS1

BESV TRS1

Award-winning manufacturer BESV have a solid reputation in the world of electric bikes, and their TRS1 e-mtb is no exception.

Electric Mountain Bikes are notoriously heavier than road bikes. Adding in the motor, battery and other gear that comes with an electric bike and it makes them even more unwieldy. The TRS1 is one of the lightest top-end models on the market.

Specs

Type of BikeClass 1
MotorShimano STEPS E8000, 500w
BatteryLithium battery, 36V, 14Ah; 504Wh
Max Speed20 mph
Max Distance60 miles
BrakesShimano XT M8000, 180mm Disc
Charging Time3.5 to 4 hours
Weight43 lbs
Price$6,499

What We Loved

While this is a pricey model, you do get what you pay for.

The TRS1 comes with very responsive hydraulic brakes and a solid rear suspension fork for a reasonably comfortable ride even on the toughest of terrain. This is why a lot of people view them as one of the best e-bikes in their weight range.

The carbon frame is very robust but ultra-lightweight. Ditching the aluminum frame is one of the reasons the bike ends up being so light overall. It weighs under 2kg!

You will have no trouble powering up steep ascents with the 11-speed drivetrain and a 500w high-quality Shimano motor.

Everything is integrated well, it looks sleek and could be confused for a traditional non-electric mountain bike. It would be just as at home on rough, steep trails as it would be if you want to use it for commuting. They may not be true hybrid bikes, but they are very versatile.

Why it Might Not Work For You

This bike is exceptionally high spec, but it does have a price point that reflects this. It would really only suit experienced trail riders and those that are going to get plenty of use out of their investment.

While the hard-tail suspension helps to keep the weight down, it does mean that this is not as comfortable a ride on rough terrain as a full-suspension model would be.

Overall Verdict

If you are a newbie to mountain biking, it may not be the best investment.

Serious trail riding enthusiasts will no doubt appreciate why this bike is one of the most expensive we have reviewed. It is so light for an e-mtb, and it has responsive brakes, a powerful motor and battery.

Lightest Bikes That Didn’t Make Our List

We would have loved to have featured the Orbea Gain M20i.

Spanish manufacturer, Orbea have a stellar reputation for their high specification road bikes. Their recent electric bike model has quickly generated a lot of chat because of how light they are managing to keep them.

It is just launching in the US, so it is not yet widely available. When it is, it will be sure to attract a lot of attention given that this e-bike weighs less than 27 lbs!

It looks like the Orbea M20i may be available for order through American dealer Jenson if you want to take a peak. While it is expensive at $5,799, this seems reasonable given you can expect a top of the range bike with such a feather light weight. 

We would also have loved to have reviewed the One eCycle F1 from German maker Coboc. These road e-bikes weigh in at just 24 lbs! They are not widely available in the States, unfortunately.
