proper use & sAfety iNfo
Before taking the bike for a ride, ensure that all components are attached properly.
Neglecting to do so may cause issues in the future. Make sure you know about the
local laws regarding electric bicycles in the areas you’re riding in and abide by the
regulations. At FLX, your safety, comfort, and happiness are of great importance to
us and we can’t stress enough how important the use of proper safety equipment is.
Although it may not be required by law, we highly recommend the use of pads and
a helmet. Make sure to wear appropriately bright clothing during the day and use
head and tail lights at night to increase visibility. Please use proper cycling hand
signals and always be cautious when riding - whether you’re in a bike lane or not.
While FLX bikes are built for heavy use, proper care and maintenance should
be performed to maintain optimal performance. For cleaning information see:
CLEANING AND CARE. Most adjustments to your FLX can be performed with
basic tools. Larger issues should be handled by a qualied bike mechanic.

pedal cranks to the motor shaft) after riding the rst 50 miles, and every 100 miles
thereafter. They should be tightened to 40-50NM, failure to maintain this tightening
torque may result in the crank arm falling o during a ride, which could cause a
serious accident.
