For Sale: Pendix edrive 300 plus additional 300 battery

Hi, I am selling my Boardman road bike size large frame, which had a Pendix edrive 300 system professional fitted. It can easily be transferred to any tandem bike, hence my reason for advertising here. I also have an additional 300 battery & mains charger to extend the range. The cost of a new Pendix edrive 300 system is £1115 and the additional battery costs £431, so in total it would cost £1546 to buy new plus the Boardman Road bike which is in full working order. I'm am only asking £300 which is a bargain for someone who wants to convert their tandem to an e bike.

Pendix eDrive300

The Pendix eDrive embodies cutting-edge motor technology, seamlessly combining torque, functionality, and an exceptional riding experience. As a versatile eBike retrofit drive, it can be fitted to almost all bike types and frame models. This allows you to transform your favorite bike into a powerful and stylish eBike in no time at all - without compromising your individual style.

The Pendix eDrive is made up of two central components: the battery (ePower) and the motor (eMachine).

Thanks to the Pendix eDrive300 conversion kit, your bike becomes a reliable and powerful eBike. The system fits almost any type of frame, whether city, trekking, cargo or mountain bikes, there just needs to be enough space for the battery and motor on the frame. It can be fitted regardless of the wheel size, gearing or brake system. The system supports both belt and chain drives. It must be located on the right-hand side of the bike and it is also necessary for your bike to have a BSA bottom bracket. The Pendix eDrive300 is ideal for your routes from 37 km to 72* km in length. The complete system weighs just 6.9 kg.
The gearless mid-motor is mounted in place of the left crank. Thanks to its design and position on the bike, it provides a particularly natural riding experience and is completely silent. With an output of 250 watts and a maximum torque of 65 Nm, it supports your pedal power up to a speed of 25 km/h (legally permissible maximum value for EU countries). Higher speeds can be achieved by using pure muscle power. As the motor has no gearbox, there is no noticeable pedal resistance when the battery is switched off, so you can still use your bike as before.
The 48 V Pendix ePower300 (battery) has a capacity of 300 Wh and works on the basis of modern lithium-ion technology. It can be easily removed from the bike and is fully recharged within 3 hours using the 160 W charger supplied. During the ride, the battery shows you the current charge level via the color-changing LED ring. The support levels can be selected using the rotary wheel above the battery. This smart design means you don't need an additional display on the handlebars. If you still want to have current data visible on the handlebars, you can use the battery's Bluetooth function to connect it to your smartphone and the Pendix.bike PRO app. The battery has a USB interface for charging external devices such as your cell phone. The Pendix ePower is mounted directly on the bike frame using a metal bracket.
