▶ Electric Bike Drive System

▶ A drive system that reads your mind:

Three sensors measure torque, speed and acceleration more than 1,000 times per second, ensuring perfect integration between you and your e-bike. This adaptive power characteristic of the Bosch Performance Line drive system is controlled by your pedal pressure, this ensures smooth assistance in normal riding conditions and the seamless transition to full power for strong acceleration when you need it.

▶  Peak power: 500W (250 max continuous)

▶  Peak torque: 40 Nm

▶ Assistance level: ECO: 50%

       TOUR: 110%

       SPORT: 170%

       TURBO: 250%

The level of assistance ranges between 50% and 250% depending on which power level you choose; 100% assistance equates to the motor doubling your pedaling force.


▶ Electric Bike Battery

▶ Bosch’s new e-bike batteries are easily unlocked for charging, lightweight, compact and provide state-of-the-art energy density.

▶ Modern Bosch lithium-ion batteries do not suffer from ‘memory effect’ or self-discharge issues. Your battery will charge to 50% in about 2.5 hours, depending on the charger and battery capacity.

▶ The battery supplied with the HERCULES  Rob Fold has the following performance characteristics:

RANGE: up to 110 miles

CHARGE TIME: 2.5hrs (50%)

WEIGHT: 2.6kg

▶ Electric Bike Display & Assistance Control

As well as speed, range, battery level and trip functions the display also shows you when its time to change gear for optimal range performance.

With an exceptionally smooth operating feel and good feed back it’s easy to apply exactly the right amount of stopping power whatever the road conditions. As with all Magura hydraulic brakes, maintenance is simple and spare parts are readily available worldwide.

HERCULES make 48 different models of electric bike, each designed to meet a specific need – if you would like us to help you find the perfect Hercules for you please email or call Clare or James on 0208 960 9848 (London), Keith on 01728 830 817 (Suffolk), or Martin at our Midlands branch on 0116 3666 980 (Leicester).

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.
