Also available (by appointment) for test rides, get in touch to arrange one.

Bike Status

  • 140,000 km.

  • Only motor maintenance: one set of bearings changed at 130,000 km. Cost $20 + 4 hours workshop time.

  • Battery ~95% of original capacity.

  • Paid for itself vs a 5.5L/100km gas bike.
    140,000 km / 100 km = 1,400… x 5.5L = 7,700 L of petrol. At $3/L = NZ$23,100. Bike cost NZ$22,000 used.

Anodized aluminium, cast parts and welded 1-inch square tubing.  11kg.

Features

Ride modes: Eco, Sport, Custom.  ABS (always on).  Smartphone App.

Regenerative Braking

An electric motor being spun by external forces is a generator.  The controller can capture this energy to charge the battery.  Regen is triggered by relaxing the throttle or braking and returns about 10% of energy used.  Is configurable.

Range & Recharging

Range @ 100 kph ~120 km, @ 50 kph ~240 km.  Charging 10-80% with the standard onboard 1.3 kW charger in 6 hours.  This bike runs a custom setup of three 3.3 kW chargers 10-80% in under an hour.
