Haibike 2017 SDURO HardFour 4.0)
The new SDURO HardFour was designed to inspire a new generation of riders and is the first ever eBike designed specifically for kids. Biking will become a carefree family experience as the motor will help reduce (or eliminate!) gaps in strength and stamina between kids and their parents. In terms of quality and technology, the kids ePerformance bike performs on exactly the same level as our adult bikes, but safety comes first, and this bike limits the assist to 12 mph. This eBike is a real alternative to the gaming console, and will help families ride together..
