Top 5 Eovolt (UTO) Folding Bikes
The French brand Eovolt—renamed UTO in 2025—has built a solid reputation thanks to its innovative folding bikes, which are hand-assembled near Lyon. With a motor in the rear wheel, a battery integrated into the seatpost, and a folding time of 10 seconds, this line is designed down to the smallest detail for urban mobility. Here is our selection of the five most notable models from the current catalog.
Key points to remember
- Eovolt became UTO in 2025 to expand its international reach and accommodate models without electric assistance.
- Two distinct lines: Origins (affordable and reliable) and PRO (premium technology with belt drive and automatic transmission).
- 16-inch wheels are ideal for train travel and tight spaces; 20-inch wheels offer more comfort on long trips.
- The PRO20 NE proves that a folding bike without a motor can be lightweight (14.8 kg), high-end, and completely maintenance-free.
From Eovolt to UTO: A Strategic Transformation
In 2025, Eovolt officially changed its name to UTO —a nod to “Utopia” and “Unidentified Transport Object.” While the old name emphasized electric power (volt), the new one leaves the door open to human-powered two-wheelers. The brand positioning remains the same: high-end, refurbished Eovolt folding bikes, hand-assembled in the Lyon region and designed for city life.
The lineup is now organized into two series: the Origins series, which is affordable and durable, and the PRO series, which focuses on innovation—featuring Gates Carbon Drive belt drives, automatic shifting, and finishes with no visible seams. If you’re wondering about the weight of an e-bike before making your choice, this factor is a key consideration across the entire UTO catalog.
Our Top 5 UTO (Eovolt) Folding Bikes
1. UTO OG20 — the ultimate all-around model
The Best Seller the lineup. Thanks to its 20-inch wheels, it offers a sense of stability similar to that of a classic city bike. Its 40 Nm motor, hydraulic disc brakes, and wide tires make it a reliable companion on all types of surfaces. The battery, housed in the seat post, blends discreetly into the frame. Range: up to 70 km (378 Wh) or 100 km (504 Wh). Folds in 10 seconds to the size of a wheeled suitcase.
2. UTO PRO20 — the flagship
Winner of a Eurobike Award, the PRO20 pushes the boundaries of electric folding bikes. Its Gates Carbon Drive belt drive eliminates the need for a greasy chain and the risk of staining your clothes. Gears shift automatically based on speed and pedaling force—ideal for city riding, where you’re constantly stopping and starting. Its carbon fork absorbs vibrations, and it has a range of up to 80 km. A bike that’s as unobtrusive as it is efficient.
3. UTO OG16 — the king of compactness
Weighing just 16 kg and featuring 16-inch wheels, the OG16 is the most compact and lightweight model in the electric series. It slips effortlessly under a train seat, under a desk, or into the trunk of a city car. Its 250 W (40 Nm) motor and 231 or 250 Wh battery offer up to 50 km of range—enough for most commuters. For long, sporty rides, you’ll want to opt for the 20-inch models; for the “last mile” and intermodal travel, it’s unbeatable.

4. UTO PRO16 — the premium pendulum
The PRO16 combines the ultra-compact size of the 16-inch model with the high-end technology of the PRO series: Gates belt drive, automatic gears, Samsung battery, built-in smartphone holder, and a discreet compartment for the Apple AirTag. Its self-locking hinges make unfolding even faster and safer than on the Origins models. For commuters who want the best without compromising on size, this is the one.
5. UTO PRO20 NE — the non-electric version
A premium folding bike… without a motor. The PRO20 NE features the award-winning frame of the PRO20 and strips it of all electronics. The result: just 14.8 kg, a Shimano Nexus 7-speed drivetrain, a Gates CDN belt, and Shimano hydraulic brakes. Without the resistance from a motor or battery, it rides surprisingly sportily. It can even coast at a red light. Climbing the steps to the subway or a train station becomes a breeze.

Expert Advice
For commuters who combine biking with public transportation, the actual weight when folded is the deciding factor. Under 16 kg, the bike becomes truly portable—you can carry it up stairs with one hand. Above that, it’s still manageable, but you quickly start to feel the weight in your shoulders. The OG16 and the PRO20 NE are the only two UTO models to exceed this threshold.
Conclusion: A Model for Every Purpose
Eovolt’s transition to UTO marks the coming of age of a brand that now knows exactly what it wants to be: the French benchmark for premium folding bikes. The choice is clear: OG16 or PRO16 if every centimeter counts on the train; OG20 or PRO20 for longer, more comfortable rides; PRO20 NE for those who want absolute lightness and zero maintenance.
