RadExpand 5: Electric folding bike with 72 km range launches in Germany

Manufacturer Rad Power Bikes is now also launching a new electric folding bike (or e-folding bike) in Germany with the RadExpand 5. The benefits include a range of up to 72 kilometers and the fairly low total weight of 28 kg.

RadExpand 5: E-folding bike launches in Germany

The now fifth generation of the electric folding bike shows itself improved in detail in all respects. Thus, the RadExpand 5 from Rad Power Bikes relies, among other things, on thicker tires, while the weight has been noticeably reduced compared to its predecessor.

The e-folding bike is equipped with 20-inch and 4-inch wide tires, which are supposed to be puncture-proof and have a reflector strip and are supposed to score with a convincing riding experience.

It is powered by a 250-watt hub motor on the rear wheel, which offers pedaling assistance with a cadence sensor and pushing assistance. Also offered is a half twist throttle including on/off switch, while front and rear mechanical brake discs with a diameter of 180 mm are used.

Shifting is in seven gears with a 7-speed MicroShift RD-M26 rear derailleur, while the handlebars are adjustable and can be extended and retracted to suit individual size and riding style.

Up to 72 km range

The RadExpand 5 integrates a 672 Wh battery, which should realize a range of 40 to a maximum of 72 kilometers per charge. Of course, this depends on the riding style, the strength of the pedal assistance and the respective terrain.

With regard to the design and the range, one orients oneself at the similarly stored Blaupunkt Enno folding e-bike, which the manufacturer had presented at the end of June. The UltraTRX E2 Terminator unveiled at the beginning of August, on the other hand, has considerably more steam under the hood, but is unlikely to come to Germany in this form.

Connectors and wiring harnesses of the folding e-bike made of aluminum are waterproof, charging is done at standard sockets with the help of the 48V, 2 amp charger. At the front, the e-bike offers LED lighting, while a rear light including brake light function is integrated at the back.

A rear rack is already included in the e-bike. It offers a load capacity of 25 kg, while a luggage rack for a maximum of 14 kg can also be attached at the front – as an option. In total, the RadExpand 5 weighs 28 kg and offers a permissible total weight of 125 kg.

Thanks to a revised geometry of the frame, the e-bike should also be easier to ride compared to its predecessor. However, the folding bike is designed more for smaller riders. The manufacturer speaks of a size between 147 cm and 178 cm.

Price and availability

The bike Power Bikes RadExpand 5 can be ordered now directly from the manufacturer, although currently only the model in white color is available and will be delivered within 15 working days. The manufacturer’s RRP is 1,499 euros, front luggage rack, rear view mirror, phone holder and other accessories are also optionally available, at extra cost.
