Dahon Unio E20 Mid Drive Folding Electric Bike
$2,699.00
Dahon Unio E20 Overview
The Dahon Unio E20 is a premium mid-drive folding electric bike built for serious urban commuters who want the natural ride feel of a mid-drive motor in a compact folding package. Powered by a 200W mid-drive motor with central-axis torque sensor and a 36V Samsung lithium battery hidden in the seatpost, the Unio E20 delivers up to 100 km (62 miles) of pedal-assist range with the responsive, balanced feel that only mid-drive systems provide.
Key Features and Benefits
- 200W Mid-Drive Motor: Mid-drive system delivers superior efficiency, high torque, and excellent climbing performance compared to hub drives at the same wattage by multiplying torque through the bike's drivetrain gears.
- Central-Axis Torque Sensor: Detects both pedaling torque and cadence simultaneously, responding in 0.01 seconds for smooth, intuitive assistance that feels like a strong tailwind.
- 36V 9.5Ah Samsung Battery Hidden in Seatpost: 345Wh Samsung lithium-ion cells integrated discreetly into the oversized seatpost for clean styling and a stealthy non-electric aesthetic. IPX6 waterproof rated.
- Up to 100 km (62 Mile) Range: Premium battery capacity delivers genuine all-day commuting range on lowest assist mode, paired with mid-drive efficiency.
- 9-Speed Mechanical Drivetrain: Real 9-speed gearing provides wide gear range for climbing leverage, fast cruising, and matching motor output to terrain for maximum efficiency.
- Five Pedal Assist Levels: Five distinct assist levels for personalized power delivery up to 20 mph (Class 1 compatible).
- ViseGrip Folding Hinge: Premium folding hinge folds the bike down to 32 x 16.5 x 28 inches for storage, transit, and vehicle trunk transport.
- DELTEC Cable Frame Reinforcement: Patented diagonal cable transforms the frame into a stable triangular shape, reducing folding-frame stress and greatly improving load capacity and service life.
- Dalloy Double-Butted Aluminum Frame: Dahon's proprietary aluminum alloy claimed to be 20 percent stronger than standard 6061 aluminum, keeping bike weight to 41 lbs while maintaining rigidity.
- Dahon Disc Brakes: Custom Dahon disc brakes deliver weather-resistant stopping power.
- 20-Inch Wheels with 2-Inch Tires: Aluminum 20-inch wheels with custom 2-inch Dahon tires deliver stable urban riding with manageable folded footprint.
- LED Auto Lighting: Headlight and tail-light with automatic on/off function for safe nighttime commuting.
- Rear Cargo Rack: Integrated rear rack accommodates panniers, packages, and commuting cargo.
- EN15194 Safety Certified: Tested to European electric bicycle safety standards.
Who Is This For?
The Unio E20 is for daily commuters who want the smooth, natural ride feel of a premium mid-drive system in a folding package, with serious range for longer commutes. If you've outgrown entry-level folding e-bikes and want mid-drive efficiency, 9-speed gearing, hidden battery aesthetics, and 60+ mile range without sacrificing portability, the Unio E20 is Dahon's flagship folder for you.

Frequently Asked Questions
What is the range of the Dahon Unio E20?
The Unio E20 delivers up to 100 km (62 miles) per charge with the 36V 9.5Ah Samsung battery on lowest assist mode. Mid-drive motors are significantly more battery-efficient than hub drives at the same wattage thanks to drivetrain leverage. Real-world range varies with rider weight, terrain, and assist level.
How well does the Dahon Unio E20 handle hills?
The 200W mid-drive with central-axis torque sensor handles hills better than 250W hub drives at the same wattage because the motor multiplies torque through the bike's 9-speed gears. Drop into a lower gear on steep terrain and the mid-drive compounds its output for serious climbing capability.
Does the Dahon Unio E20 come assembled?
The Dahon Unio E20 ships approximately 98 percent pre-assembled. Most riders complete final setup in 15 to 30 minutes (installing the seat and pedals). Detailed instructions are provided.
What is the weight limit for the Dahon Unio E20?
The Unio E20 supports typical premium folding e-bike rider capacity. The Dalloy aluminum frame with DELTEC cable reinforcement is engineered for daily commuting loads.

Meet the Founder
Electric Bikes Paradise was founded by Trevor Fenner, an e-bike enthusiast who has been riding electric bikes since around 2013.
Trevor was already running an online business selling bicycles when he saw a growing need for a dedicated electric bike retailer — one that offered a wide selection, knowledgeable customer service, and educational resources to help people find the right e-bike for their lifestyle.
In 2019, he launched Electric Bikes Paradise to focus exclusively on electric bikes and the rapidly growing e-mobility category. Today, we remain online-only by design. Operating without a brick-and-mortar storefront allows us to offer our customers competitive factory-direct pricing, faster shipping, and world-class customer service by phone, email, and live chat — all without sacrificing any of the things that made Trevor excited to start this business in the first place.
How We Give Back
We love to give back to our community. We've partnered with PeopleForBikes, a leading non-profit organization dedicated to making bike riding better and more accessible for everyone in the USA.
It's amazing what a difference an electric bike can make in a person's life — from reducing car dependence to improving physical and mental health. Please consider donating to our fundraising campaign for PeopleForBikes. All proceeds go to help people in communities across the USA get access to safe bike infrastructure, get more people riding, and create healthier, more sustainable lives for their families.

You can reach our customer support team Monday through Friday, 9am to 5pm MST.
You can chat live with our customer support team during business hours — just look for the chat button in the lower-right corner of our site.
