DYU A5 – A foldable electric bike that revolutionizes everyday life and adventures
Top Gear-inspired test drive in Kruunuvuorenranta
Sähköpyörätehdas sent the DYU A5 folding electric bike to Helsinki's Kruunuvuorenranta, where the shared test drive location is located. The test team waited with excitement – and when the bike was unboxed, the atmosphere was like a test drive of a new sports car.
The first sprint on the smooth asphalt of the coastal road revealed that the DYU A5 is no ordinary ride. The lightweight aluminum frame and 350W motor took it to a top speed of 25 km/h in no time. The hills did not slow it down – the engine torque carried the rider up the slopes of Kruunuvuori like an electric wind at the back.
City driving with ease and style
In the center of Helsinki, the DYU A5 shone with its agility. Stopping at traffic lights was smooth, and when the light turned green, the bike immediately accelerated. The disc brakes provided confidence and the foldable structure made it easy to move around: the bike fit on the subway, bus, or in the trunk of a car without any hassle.
The terrain invites you to adventure
When the route turned to sandy paths and coastal cliffs, the DYU A5 showed its versatility. The suspension front fork and seat suspension softened the bumps, rocks and roots - the ride felt stable and comfortable. Off-road, the DYU A5 combined traction and power in such a way that riding on gravel roads became an experience.
Lightweight yet durable construction
The DYU A5 weighs just 22 kilos, but has a load capacity of up to 150 kilos. It is designed to withstand the frequent stops of a city day as well as longer trips in the countryside. When folded, it takes up little space, but when unfolded, it offers a full-fledged e-bike riding experience.
