HYBRID-E
 
Motor and Battery
At only 3,4 kg, this integrated 250W all-in-one electric motor and
battery, transforms your GOrilla to a slick and smart e-bike.
GOrilla HYBRID is charged in closest electrical socket by connecting
the charger to the rear wheel axel.A 3-hour charge will give you
a 30-40 km assisted ride, or more if you use the regenerating braking
function that charges the battery while riding.The built-in Li-ion battery
has 3000 cycles and is replaceable.

Ride and adjust
To start up your engine you ride the GOrilla HYBRID up to 8 km/h and
then back pedal 3 revolutions. The engine turns off automatically after
2 minutes standing still. If you want to adjust the motor settings you
simply download the Bitride app to your mobile. Bitride connects to your
GOrilla HYBRID via Bluetooth and here you can adjust your motors assist,
top boost speed (25km/h) and regenerate braking function. Bitride also
indicates your speed, battery status and engine power – however the app
does not have to be running for the e-bike to work.
