Every year, it seems like there’s a new headline about the world’s lightest electric bike. Each year, engineers manage to shave a few more grams off of an exotically designed frame built with even more exotic materials. And each year, the continuously lower weight is balanced by continuously higher prices – often exorbitantly high. But now Dahon has bucked that trend, offering us an incredibly lightweight electric bike at a price that normal e-bike riders can afford. Meet the Dahon K-Feather.
To put things in perspective, some of the previous lightest electric bicycles have included the 11.8 kg (26 lb) LeMond Prolog at US $4,500, the 11.75 kg (12.59 lb) Trek Domane+ SLR at US $8,999, and the 10 kg (22 lb) Hummingbird Flax folding e-bike at US $6,050.
So with that in mind, please allow me to introduce you to the new Dahon K-Feather. This is a 12 kg (26.5 kg) folding electric bike priced at an incredibly reasonable US $1,199 in North America or €1,499 in Europe.
Sure, it’s not the absolute lightest folding e-bike we’ve ever seen, but it’s 90% of the way there and at a quarter of the price. Plus, it comes from Dahon, which is one of the most respected names in the folding bike world and is largely credited with paving the way for the booming folding bike industry we see today. Since the 1980s, Dahon’s innovative designs have been imitated around the world, yet the folding bike maker has continued to innovate and stay several steps ahead of competing brands.
The K-feather achieves its extra low weight through the combination of a novel frame design employing Dahon’s patented frame designs, including the company’s DELTECH technology and “super down tube,” which help improve rigidity and robustness while reducing weight.
The electrical system on the K-Feather is also a featherweight, keeping the e-bike largely in the last-mile category. While the battery claims a maximum range of up to 24.8 miles (40 km), real-world riding and hilly terrain could reduce that range. Still, clever designs like a system that automatically shuts off the extra motor power when detecting a downhill segment help to eke out more range from the small 24V and 5Ah battery.
The ultra-lightweight 250W hub motor also offers just 32 Nm of torque, meaning the assist is more of a helpful push than a powerful shove. But with the inclusion of a torque sensor for the pedal assist, that push comes on quickly and reliably, making the bike feel more like a traditional analog bike being pedaled by someone with extra strong legs.
With 16″ dual-wall rims and 14g spokes, this isn’t the heavy fat tire folding e-bikes we’re used to in North America, and the capacity reflects that. The K-Feather is rated to support riders weighing up to 105 kg (231 lb), though the highly adjustable seating position can support a range of rider heights from 145 to 190.5 cm (4’9″ to 6’3″).
Coming in six colorways, the Dahon K-feather folding e-bike is now available in the US and has launched for pre-order in Europe, with shipments there expected in September.
I had a bit of a preview of the K-feather on my last trip to China when I was able to visit Dahon’s headquarters and test ride the bike.
I still can’t believe how light it felt, both underneath me and while folding it up and carrying it around. Be on the lookout for that full experience from my trip, coming soon.
Electrek’s Take
The K-Feather represents a compelling milestone not just for Dahon, but for the entire folding e-bike market. By delivering a truly lightweight, compact, and fully electric folder at an impressively affordable price point, Dahon has made minimalist e-mobility more accessible than ever.
It’s not just a bike for die-hard lightweight e-bike connoisseurs; it’s a real-world solution for commuters, travelers, and apartment dwellers who want the freedom of electric assist without the bulk or the sticker shock. If the goal is to get more people on two wheels, the K-Feather might just be one of the most important steps forward yet.
Coming in at less than half the weight of most folding e-bikes, and still a fraction of most lighter-duty folders, the K-Feather’s modest performance makes it a great urban ride for those who favor compact size and light weight. In fact, I think it might be perfect for my mother-in-law, who needs an e-bike to get to and from the train she takes to work, but also needs it to be light enough to carry up to her second-story apartment. Hmmm, perhaps I should have her do a review for us…
