Description
Who is this bike suitable for?
This one's pretty obvious - It's for kids who require that little bit of assistance! This 24" wheeled unisex kids electric bike is suitable for children ranging from the age of 9 onwards. A kids specific chassis and refined Yamaha eBike system.
After much research into e-mountain bikes, and visiting a number of dealers, I was blown away by the brilliant service given at e-bikeshop. Martin really knows his stuff, and took into account everything I was looking for in an e-bike. I am now the very proud owner of an AWESOME Haibike, and am totally confident in the back up and aftersales. If you want an e-mountain bike, get down to e-bikeshop!!
New Features
For 2016 an all new sDuro model! Finally we have a 24" kids electric bike. Do your children get fed up and tired mid way through the ride?
Do you want to ride further with your family? Or does your child require some support?
The new Haibike sDuro HardFour RX is the answer!
The sDuro HardFour RX offers refined kids geometry and a smaller 24" wheel. Suitable for boys or girls with an average age of 8 onwards.
This simple spec'd bike is great for children and Haibike have included a refined version of the 2016 Yamaha system, learn more further down the page.
The 2016 sDuro HardFour RX features a 9 speed Shimano Acera gear system with simple to use trigger shifters to give the kids full versatility across varied climbs and descents. Remember with crank drive you can use the gears with the assistance.
The smaller 24" wheels offer kids full control and stability. Small enough to manoeuvre around, but big enough to take on a full day's ride and follow the parents through varied terrain.
Although kids sized wheels, Haibike have built them with decent disc hubs and double wall rims.
On the 2016 sDuro HardFour RX we see the Tektro hydraulic disc brakes. Simple to use and fairly maintenance free, it's a good option on this 24" kid's bike.
With the electric assistance we want to ensure braking power remains solid.
Thrown into the mix are a set of 24" Schwalbe Table Top tyres. Both lightweight and durable in their construction, they allow a faster rolling resistance while maintaining grip at the same time. A good choice for a mixture of surfaces.
Yamaha eBike System
The new Haibike sDuro HardFour RX is powered by the latest Yamaha electric bike system. Haibike has partnered with Yamaha to bring a brand new line of sDuro eBikes, this 250w motor offers up to 280% assistance and peaks at 60Nm of restricted torque (on this kids version).
The assistance is set in 3 levels on the kids version - 'Eco', 'Standard' & 'High'. This allows the child to fine tune the amount of assistance required. We also see a new set of controls that loose the LCD screen in replace of simple on / off power and assistance, easy to use buttons.
The Haibike sDuro Hard Four RX 2016 eBike is offered with the largest 400Wh Yamaha battery to give a full day's ride time. Now your son / daughter can join you for the longer rides too!
On the Kids version the assistance speed is lowered down to 12.5mph. We want children to have fun whilst maintaining a safe pace. We also remove the walk assist and simplify the levels to make it as user friendly as possible.
You can learn more / read reviews of the Yamaha eBike system on our blog pages.
