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.

Rotwild electric bike motorWith 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.

All of our electric bikes are fully assembled, checked and road-tested by our expert staff prior to delivery.

High quality electric bikes last for many years so it’s important you get the one that’s right for you – but there are so many to chose from! Online research can help you narrow the options but by far the best way to ensure you’re making the right choice is to visit one of our branches, discuss you needs with one of our friendly experts, and test-ride one or all of the many brands and models we stock – there’s no substitute for spending time in the saddle!  Once you’ve made your choice you can ride your new e-bike away. Don’t worry if you can’t spare the time or are just too far from one of our shops, we’ll be happy to help you choose over the phone or via email and deliver your e-bike to your home at a time that best suits you.

▶ Personal Home Delivery

no brown box delivery1

If you choose this option our experienced staff will deliver your electric bike in person to your door fully assembled and tested at a pre-arranged time, and will work with you to ensure every thing is perfectly adjusted to suit your size and preferred riding style before that all-important test ride. We’ll spend time with you to make sure you’re happy with your choice and understand all its features, so be ready to put the kettle on!

After your test ride, when everything has been fine-tuned to your liking and you are comfortable with your e-bike we will fit any accessories you may have ordered – or those you might already have – a favourite old saddle perhaps, a particular bell, or pair of trusted hand-me-down panniers.

Only when we are certain you are completely confident in your e-bike choice and understand how everything works will we leave you to enjoy your new found freedom.

The cost of this personal service varies depending on your location and whether you would prefer evening or weekend delivery, please email or telephone us for an estimate.

Note: After you have inspected the bike, found it to be in good working order, and agreed that this is the right bike for you, the sale will be complete. If we have delivered in person please be sure you are happy with everything before we leave as we cannot accept returns once our delivery staff have driven away unless the e-bike can been shown to have a design or manufacturing fault. We then retain the right to determine the appropriate remedy, be that on-site repair or replacement of a part, a replacement electric bike, or full or partial refund. If the reason you decide not to accept the bike could have been established easily before you ordered it (e.g. you ordered a white bike and later decided you prefer black), we reserve the right to make reasonable charges for delivery and or any work done to the bike prior to delivery.

▶ Evening and weekend delivery:

Because few of us are at home during working hours these days, we offer the option of our personal home delivery service on Saturdays and Sundays, and evenings during the week.

The cost of this personal service varies depending on your location and whether you would prefer evening or weekend delivery, please email or telephone us for an estimate.

▶ Courier Delivery

Before being delivered via courier your e-bike will be fully assembled and road tested. Once we’re happy with all aspects of its performance we will carefully pack it in a sturdy box ready for shipping.  Please note that the pedals are removed and handlebar rotated inline with the frame for packing so these will need to be fitted and adjusted on arrival. This is simple to do but should you like reassurance we will happily talk you through the process over the phone, we can also arrange a phone-call with your local, trusted bike mechanic if you decide you would rather give the job to them.
