Picture this: You’re riding your cycle, gliding past the traffic and humming your favorite songs—all while barely sweating. And, when you arrive at the destination, you simply fold and tuck it in a corner. That’s the appeal of a lightweight electric bike. They boost cycling with electric power with the bulk—but a lightweight, natural feel that makes your daily commute or on-bike adventure a breeze.
Fortunately, there are many choices when it comes to buying the lightest electric bike. And to keep you from getting lost in specs and marketing hype, we’ve curated this list of top lightweight e-bikes for effortless riding.
But before that…
What weight makes the Lightest Electric Bike 2025
You might have heard about e-bikes weighing below 18kg or even 15kg. Such e-bikes may be portable and fit for apartment dwellers and short rides. But in our opinion, e-bikes below 25 kg often sacrifice battery capacity, motor power, or other specs.
Remember that a good lightweight electric bike isn’t only the number on the scale—it’s the balance between low weight and performance. For example, ENGWE P275 SE weighs just 24 kg while still offering outstanding performance like a Smart Torque Sensor, 100KM max range, and 36V 13Ah battery capacity. You can easily carry it up a flight of stairs, it looks amazing, and rides like you haven’t turned on the electric assist.
What determines the weight of an e-bike?
These are some components that build up the weight of an e-bike, and these mainly are:
Battery: Battery is perhaps the biggest determining factor. The more battery capacity, the longer the range, and the heavier it is. E-bike batteries usually weigh between 2.5 and 4 kg. Plus, the material of the battery also affects its weight; for example, a lithium battery is lighter than a lead-acid battery.
Motor: Similar to the battery, the higher the motor power, the heavier it becomes. E-bikes typically use two types of motors: hub motors and mid-drive motors. Mid-drive motors are heavier, but they improve the performance and help provide hill-climbing ability.
Frame/body: Steel, carbon fibre, and aluminium alloy are the common materials used for building the frames of e-bikes. Steel is stronger but heavier, while carbon steel is ultra-light but may not be as durable. So, the lightest electric bike is the one that balances weight, performance, and usability. Aluminium alloy is a material that is both lightweight and strong.
Wheel size: The bigger the wheels, the better the stability, but the heavier your bike will become. The material and thickness of the tyres also affect the e-bike’s overall weight.
Accessories: Add-ons like phone mounts, fenders, baskets, and lights add extra weight as well as usability to your e-bike.
Lightest E-Bike of 2025: Our Top Recommendations
To create this list, we have tested some top models available on the market, read their customer reviews (from real riders), and analyzed key specs from verified sources. So, every e-bike in this list meets the lightweight standards:
ENGWE P275 SE
At 24 kg bike weight, ENGWE P275 SE tops our list not only for being lightweight but also for the practicality and performance it offers. The lightweight aluminium frame keeps the overall weight manageable without compromising durability, allowing for stress-free and sweat-free riding. It’s so light that you can carry it up stairs or slide onto a bus rack.
Using Engwe’s exclusive AI algorithm and Smart Axle Torque System, the P275 SE bicycle ensures ultra-fast pedal response, faster than the blink of an eye. With commute-ready features like hydraulic disc brakes, a 36V 13Ah battery, and app connectivity, ENGWE P275 SE perfectly balances weight and practicality.
RadKick™ Belt Drive Electric Lightweight Bike
With a compact frame, step-through design, and a weight of around 24kg, RedKick is a lightweight commuter with all performance essentials without the heavy frills. It’s available in two modes: the classic 7-speed for those who prefer gears, and the belt-drive single-speed drive for those who just want to hop on and go.
LeMond Prolog E-bike
The sporty e-bike is loved for its looks, lightweight design, and small 250W rear hub motor. The carbon fibre city e-bike is ideal for short commutes to work, shops, or weekend social rides. The low weight—around 11 kg—certainly helps, and it feels like an endurance bike with a flat bar.
Although Prolog is not a featherweight bike in comparison with unassisted bikes, it’s still light enough to be carried upstairs. What’s more? With wide tyres, this will become your lightweight fat tyre hybrid e-bike.
Hummingbird Folding Flax E-Bike
Hummingbird is another lightest electric bike on the market. In 2024, Hummingbird Electric launched the flax version of its electronic bike, which weighs just 10.3kg and is 600g lighter than its predecessor (the carbon fibre version).
So, the Hummingbird Flax e-bike is highly portable and easy to carry on public transport and upstairs. The flex fibre frame gives the e-bike its strength and stiffness—all without adding weight and maintaining its sustainability.
Urtopia Titanium Zero
Weighing only 10.8 kg, Titanium Zero is perhaps the lightest and smallest e-bike on the market. The bike features a 3-D printed titanium frame, a lightweight motor, and a solid-state battery, bringing performance at minimal weight. But, Titanium Zero is a recent launch from a relatively new brand. So, you might be sceptical about the e-bike’s performance, despite the company’s claims.
FAQs: Lightest Electric Bike
