HERCULES NOS SPORT 27.5 Plus
The HERCULES NOS SPORT 27.5 Plus features the high-torque 90Nm BROSE motor, 120mm Rocks Shox XCR AIR suspension (with lock-out), Shimano BR-M395 hydraulic disc brakes and the 20 speed Shimano Deore gear system. As with all BROSE powered e-bikes, when switched off or at speeds over 27.5kmh the 90 Nm BROSE e-bike drive system is disengaged completely so has zero pedaling resistance.

▶ DRIVE UNIT
With a whopping 90Nm BROSE toque on tap it has a huge power advantage over its non-Brose rivals.
The beating heart of this HERCULES is the peerless BROSE S Drive Unit. For 2018 the Brose has new software giving more low-speed torque and smoother power delivery across all speed ranges. Its main ingredients are aluminum, magnesium, experience, enthusiasm and …helical epicyclic gears! Designed in Germany, its made there too.
Where other well known e-bike motors are built to a price point, the Brose S is designed and manufactured to a quality standard, incorporating precision engineered helical epicyclic gears. These are much more expensive to manufacture but offer dramatic performance and wear rate improvements over the cheaper spur gear tooth profiles that the completion use.
In the simplest terms spur gears transfer power from the driving gear to the driven gear via only one or two teeth at a time, whereas with helical gears power is transferred by three connecting teeth at a time. This results in less wear, less noise, less friction and a smaller and lighter drive unit.
Despite its small physical size the BROSE S produces a market leading 90 newton meters of torque. It does this quietly, reliably and without fuss. The company’s sensor concept is the only one of its kind on the market today: it measures rider pedal force no fewer than 420 times a second, delivering smooth, vibration free assistance.
Brose Drive Technology is a division of the Brose Group, one of the most innovative and successful suppliers to the international automotive industry, employing some 22,000 employees – 2,500 of them engineers – at 57 locations in 23 countries around the world. Their annual turnover exceeds €5 billion. Last year Brose manufactured 100 million electric motors. They know what they’re doing.
Decades of experience specialising in mechatronic systems for the automotive sector mean they’re perfectly placed to produce this innovative e-bike drive unit. Development and production of the Brose e-bike motor is carried out entirely in-house at their Berlin engine plant, where a dedicated team of engineers design, build and test the system at their purpose built e-bike center of excellence .
The removable Li-Ion battery is integrated into the aluminum bottom tube, ensuring the lowest possible center of gravity, and at a class-leading 650Wh the battery will drive you further than any other electric MTB in it’s class. It’s not just me! Many of our customers have had first hand experience of the Brose motor efficiency – of course the range between re-charges on a BULLS is greater than any of its competitors because it has a higher capacity battery, but that does not explain how a HERCULES with 30% more power than its rivals can run flat out for so long on one charge. Clearly, much of its range advantage is down to the efficiency of the Brose drive unit.

The Shimano Deore system is slightly heavier than XT/XTR and a little less precise but it’s a great option for those not wishing to splash out on XTR or XT gear sets.
The new DEORE dérailleur blend powerful performance with precise shifting.
▸Consistent performance in all conditions
▸Accurate chain position in every gear
▸Low-profile design keeps dérailleur safely away from trail obstacles
▶ Shifter Shimano Deore Rapidfire
With its advanced ergonomics the new DEORE shifter delivers seamless control and instant response.
▶ Rock Shox.
The Rock Shoxs Solo AIR fork features revised oil flow to improve control and consistency, improved linear damping and redesigned seals to reduce friction. Ultra durable coating ensures dependable performance through the seasons and anodized adjusters enable you to tune the ride to your liking.
▶ Shimano M395
Huge braking performance and low weight doesn’t have to be expensive! The M395 system provides good power and sensitivity even on the most difficult terrain.
This electric mountain bike has an inductive transfer Monkey Link system built-in! Monkey Link makes it possible to fit a range of accessories such as bicycle lights and mudguards with built in lights to the bike with no additional electrical connections – accessories such as front and rear lights are powered from the electric bike’s main battery via electromagnetic Inductive transfer.
