6. How things work

6.1 General

It is extremely important to the performance, enjoyment and safety of your Lafree Twist and yourself to understand how many of the features of Lafree Twist operate. You should not assume that the way things have worked on previously owned bicycles operate similarly on Lafree Twist, even if you’re an experienced bicyclist. Be sure to read – and to understand – this section of the owner’s manual. If you have even the slightest doubt about how any of the mechanical features of Lafree Twist operate, talk to your authorised Lafree dealer.

6.2 Power control switch

The power control switch is located on the left-hand side of handlebar (see fig. 30 and 06).

Turn the switch to “ON” or “ECO” position and the motor will provide you assist power when you pedal the bicycle.

“ON” indicates the assistance power in normal mode and “ECO” indicates economic mode. In “ECO” mode, the assistance power is about half of the normal mode. It could save the energy consumption and extend the range. The “ECO” mode saves energy consumption and extends the range with approx. 50%.

The power control switch has a LED that emits RED light in the following cases:

When you switch from “OFF” to “ON” or “ECO”, the LED will light up for approx. 2 seconds, indicating that the system is okay.

When the LED lights up when riding, it means that something is wrong !

The light will keep burning (steady, not blinking) for approx. 3 minutes, then it will shut off. Turn the switch to “OFF” and back to “ON” or “ECO” again.

-When the LED lights up for approx. 2 seconds, the system is okay and you can continue your ride.

-When the LED lights up but it doesn’t shut off after approx. 2 seconds, there’s still a problem with the electrical system.

Finish your ride without power assistance (switch to “OFF”) and bring your bike to your Lafree dealer to have it checked as soon as possible.

Same as previous point.

The motor and the battery are protected against very high power output (more than 15A for 4 sec.), to ensure long life.

The motor shuts off and the LED will light up. It keeps burning (steady, not blinking) for approx. 3 minutes.

What to do:

Turn the switch to “OFF” and back to “ON” or “ECO” again.

When the LED lights up for approx. 2 seconds, the system is okay and you can continue your ride. Examples when or how this will appear:

-Riding uphill with high power

-Riding with headwind with high power

-Standing still (e.g. at traffic lights), pushing on the pedals while pulling the brakes. The motor supplies power, but the bike cannot move.

When the battery becomes empty, the LED will start blinking:

-when the LED blinks with 1 Hz (= 1x on/off per second), there’s just 10~-20% energy left

-when the LED blinks with 4 Hz (= 4x on/off per second), there’s less than 10% energy left. After approx. 4 minutes, the LED will stop blinking.
