Technical information:

The 252Wh (36V/7Ah) battery is integrated into the frame and is removable for easy transport.

It can be locked with a key to prevent theft.

Service life: 800 complete cycles (1 cycle = recharge from 0 to 100%). After 800 recharge cycles, the battery still works, but not at full capacity.

Warranty: 2 years. Battery and charger supplied with bike. Controllable battery for greater autonomy.

Briefly press the UP or DOWN button to change the assistance level and thus modify the motor power. Assistance can be set in steps from 0 to 5.

Level 0 means no power is supplied, level 1 is the lowest power and level 5 is the highest power.

Slide assistant mode:

Briefly press the ON/OFF button, then press and hold the DOWN button. The electric bike activates Push Assist mode, runs at a constant speed of 6 km/h and the display shows P (Push-Assist). If you release the BAS button, the electric bike immediately deactivates Push Assist mode and returns to the previous state.

GRUNDIG E20 offers a wide range of functions to meet the needs. Display elements include:

• Intelligent battery indicator
• Assistance level setting and display
• Speed display (including RT speed, max, AVG speed)
• Mileage indicator (including Trip and ODO)
• Push-Assist control and display
• Trip time display
• Backlight and backlight display control
• Error code display
• Parameter settings (wheel size, speed limit, battery SOC setting, assistance settings, etc.)
• Restore default settings function

The brushless motor is located in the rear wheel and offers 30 Nm of torque for a maximum power of 250W.

As you pedal, the motor takes you to 25km/h more or less quickly, with more or less force depending on the mode selected on the control screen.

This assistance is triggered by pedaling, thanks to a system of pedaling frequency sensors.

The aluminum frame contributes to the lightness without compromising on stability.

The side-folding system takes up very little space: at home, in the trunk of a car, camper van... your bike will be forgotten.

Fork:

Rigid steel forks for added strength.

Transmission:

• Double chainring housing to prevent derailment and protect from dirt.

TEKTRO brake calipers provide efficient, progressive braking.

Good to know:

Electric-assist bikes use more brake pads than conventional bikes, due to the weight and power of the motor.

Regular brake adjustments are essential for good braking performance.

The geometry of this bike offers optimum comfort for riders measuring between 1.45 m and 1.95 m.

Maximum weight is 130 kg (rider + luggage).

he tire pressure decreases over time. On average, the loss is 1 BAR per week.

Please remember to regularly inflate the tires: If you ride with too low pressure, the autonomy of your battery decreases, you have to pedal more, and tire punctures can occur.

Before performing any work on your electric bicycle (cleaning, electrical or mechanical maintenance), remove the battery and turn off your EAB.

Charge your battery at least every 3 months during the winter storage.

Store/charge your battery in a cool (between +10°C and +25°C), dry place away from direct sunlight.

Do not store a discharged battery (1 LED flashing) to avoid deep discharging which could impair its capacity.

Remember to recharge the battery (even when not in use) at least every 3 months to avoid deep discharge.

If you can't charge your battery regularly, switch it to standby mode, even if 1 automatic standby occurs after 2 hours.
