There are three ways to ride the E90
1. ride by pedal power alone, i.e. fully humanpowered.
2. ride by electric motor alone by operating the throttle manually.
3. ride using both together at the same time.
Unpowered riding
You can ride the E90 without activating the electrical system, or having the battery installed. Fully
human powered (normal) riding will not damage the motor or bike. Go for it.
Powered riding
Step 1 Turn on the battery
BATTERY ON/OFF SWITCH
Install the battery by sliding it into the cassette casing. It only fits one way. Push it into place
firmly and will ‘click’ into place. Using the key lock, turn the key. This locks the battery into place.
You may now remove the key for security. There is a rocker switch at the rearside of the
battery, press it and a red light will illuminate to show the battery is operational. You can test the
battery’s charge by pressing the test button on the top of the battery. Full green lights indicate a
full battery
