Small size, big experiences – that’s the Folding E-Bike Devron 20122, which won’t let you down either in the city or beyond. Thanks to its low step-through frame, getting on is a breeze—whether you’re wearing jeans or cycling gear. The lightweight aluminum frame and folding design make this bike a perfect travel companion for trains, cars, or commuting to the office. And it still packs enough power to tackle hills—the brushless motor with 35 Nm of torque will assist you when you need it most. Combined with a rear rack battery with a 14Ah capacity, it can take you up to 90 km on a single charge.
The 7-speed Shimano Altus gear shifter and reliable Shimano Tourney derailleur give you full control over the ride. The suspension fork with 30 mm of lockable travel and Kenda tires with reflective stripes can handle both urban bumps and gravel paths. Whether you’re braking at a traffic light or for an unexpected obstacle, the Tektro V-brakes provide confidence and control.
Comfort and features aren’t an afterthought here—the folding pedals, the height-adjustable stem, the ergonomic grips, the integrated lighting, and the practical rear rack with straps turn every ride into an unforgettable experience. This machine combines practicality, performance, and style. Just hop on and go!

Warning: The factory setting for maximum speed is 25 km/h to meet the European standard for e-bikes. However, the setting can be manually changed to a higher speed limit. Bear in mind that in such a case the e-bike no longer meets the required standards and cannot be used on public roads!
Note: The expected max. travel distance depends on various factors, such as the amount of electric assistance, user weight, terrain, wind and the inflation pressure, pattern and temperature of the tires. All stated travel distances are valid under optimal conditions, meaning even terrain with no wind, temperature of 20°C, extremely narrow tires with no profile and user weight under 70 kg.
