Who is this bike for?

With the amount of screens your children can access on a daily basis, it can be tough to get them out into the fresh air. That was until the sDuro HardFour 1.0 2020 made an appearance.

Built to make sure your young ones can keep up with the family unit on the longer rides, or inspire them to get on to the trails rather than playing video games all weekend…

Providing assistance up to 20km/ph (12mph) the HardFour 1.0 comes equipped with everything your child will need to take them down the trail in a controlled and exhilarating manner!

What Makes it Different?

The hard-tail style of the HardFour combined with 24” Schwalbe Table Top Performance tyres will give the comfort and control to build up an appetite for eMTB-ing.

SR Suntour forks up front with 63mm of travel will provide plenty of shock absorption while riding new terrains, while the low centre of gravity of the eBike complements this.

Electrical System

Powered by Yamaha’s 250W PW-TE motor, but limited to 12.5mph the HardFour 1.0 will be happy on all sorts of terrain.

Coupled with the 400Wh Yamaha lithium ion battery that provides a predicted assisted range of up to 95 miles (assistance mode and terrain dependent) family rides certainly wont be cut short for lack of power.

A new Yamaha LCD display will be the point of contact for your young rider's mode section, battery level and distance travelled statistics. Built with ease of use, and in a non distracting manner. The 1.7" display won't distract while on the trails!
