Haibike Sduro Electric Mountain Bike

Haibike Hardseven

If you are looking for an electric mountain bike there is something you should be aware of. Most of the lower end E mountain Bikes use very low end components which is how they sell the bike at the lower price. Haibike is probably a company that you have not heard of unless you have been in to the e bike scene for a while. The Haibike Sduro Hardseven 4.0 27.5″ Electric mountain bike brings together the Yamaha PW-ST Motor and a good package of mid range components.

Who are Haibike?

Haibike are one of those companies that have been about forever yet they are not really known in the retail world. The brand is highly respected by pro riders. Haibike have been developing Bikes in Germany since 1995 and they can call on over 100 years of engineering experience from their parent company.

This company has been at the forefront of e bike development since the very beginning.

Lets get back to the Sduro Hardseven

The Haibike Sduro Hardseven is a bit different to your average lower range Mountain Bike as you can see from the spec list below. I would just like to point out some of the key features for you.


Rockshox Recon TK Steel Spring – although this is still a coil fork, it is a good quality robust fork which can take more punishment that the usual lower end Suntour fork.


Haibike have gone for the Shimano MT400 hydraulic brake which provides more stopping power that the lower spec Tektro brakes which are very popular on the cheaper bikes.

Gear Set

This was a good choice of gearing as Haibike went for the Deore M6000 Rear and Front Mech. The Deore M600 shifters have been proven in testing and they provide smooth and reliable gear changing.


Yamaha’s new Quad Sensor System uses an angle sensor to detect the bike’s angle of climb or descent, in addition to the existing ride speed, crank rotation, and pedaling torque sensors. It’s been fine-tuned along with the Automatic Support Mode technologies.

Yamaha PW - ST

The PW ST is the new name for the previous PW SE. It benefits from the tech in the PW-X2, and features the Quad Sensor System so that it can deliver optimized assist levels for all conditions despite weighing 100g less than the previous model. The unit also offers a broader assist range that can accommodate high-cadence pedaling, and Automatic Support Mode – the ASM for the PW ST selects the right amount of assist power based on riding conditions.

Yamaha also claim to offer smoother hill starts, with the system modulating its support in High Mode during the initial pedal strokes. This can prevent wheelies or rear wheel spin outs when starting on loose ground in steep terrain.
