These cool new e-bikes use regenerative braking for a super-long range

The company that designed the original Mini Cooper has launched four new e-bikes with tiny hub-mounted batteries that offer super-long range thanks to regenerative braking.

As BikeRadar reports, Cooper Bikes (the cycling arm of the Cooper Car Company) has implemented the same type of kinetic energy harvesting system used in motor racing. Pedal backwards and the Zehus Gen 2 drive system activates engine braking while recharging the battery. You only need to spin the pedals backwards three times to start the process, but it looks like there will be something of a learning curve.

The four models in the range aren’t as expensive as you might expect, ranging from £2,099 (around $2,700 / AU$3,700) to £2,499 (around $3,200 / AU$4,400). To put that into context, our current top-rated e-bike, the Specialized Turbo Vado 4.0, starts at $4,000 / £3,900 / AU$5,000.

The entry-level model in Cooper Bikes’ new range is the Classic Singlespeed Cooper CS-IE – a stealthy singlespeed designed for city riding.

Next is the classic ladies’ Cooper CL-7E (which has a stepper frame, seven-speed gears, and hydraulic disc brakes) and the classic men’s Cooper CG-7E. Finally, the Classic Randonneur Cooper CR-7E, has a sportier road style with drop handlebars and the same steel frame as the rest of the range.

Each bike’s battery is housed in the rear hub motor and can deliver up to 60km of range on a single charge. It’s not as far as many bikes with heavy full-size PSUs, but it’s notable for a tiny hub-mounted battery.

Unlike most of the models in our roundup of the best e-bikes, none of the new Cooper e-bikes have a head unit display either, reducing the need for additional wiring. Instead, the drive system connects to a mobile app, which you can use to customize your bike settings.
