Over the years Electric Bikes have improved in performance and technology, but this has rarely kept pace with the quality of ride.

Every electric bike today has been a compromise, until today.

Airnimal has taken a fantastic folding bike and motorised it, with the superb Bionx system.

The entire package weighs less that 20kg and has a range of up to 40 miles, additionally the system has regenerative braking, whereby you put energy back into the battery when you go downhill or slow down.

The Airnimal Joey folding bike is a joy to ride, and can be folded and packed into a suitcase.

The Bionx system has a handlebar contoller with 8 power modes, a Ni-MH battery pack and a rear hub motor.

The BionX system includes a specific charger for each batter that detects and stops charging when the battery is full.

At all times you know if the charger is still charging or if the charge is complete.

NiMH battery charger (1.8 Amp/h): recharges in approximately 3 hours, whether it is completely uncharged or not.

As the Bionx system has a regenerative facility, it is also possible to recharge the battery while riding downhill or whilst braking.

Command Console

Power-Assist: Controls the 4 assistance levels.

The analog display, indicates the power supplied by the battery.

Generation: Controls the 4 generative settings.

The analog display indicates the energy transmitted to the battery.

The console includes a multifunctional odometer that displays the following information:

  • Current speed,
  • Tripmeter,
  • Odometer,
  • Chronometer,
  • Average speed,
  • Time (NEW - on 2006 models).

The control console includes a battery charge indicator that helps you manage the battery charge in order to prevent running out of energy on the return trip.

The console also includes an alarm system with a 4-digit PIN (personal identification number).

When the alarm system is activated, two wheel turns are enough to set it off.

From that moment, the motor goes into generative mode 4 and the alarm sounds.

The power-assist maximum speed is adjusted to the regulations of the country where the system is delivered:

  • Europe: 25 kph (15 mph)

The ride is incredible and at £1499 its a steal.
