The ENVO Flex is built with a solid, super lightweight, stylish and unisex hydro-formed aluminum alloy frame which is suitable for people from 4’11” height all the way to 6’5”. It is capable of a rider up to 300lbs and offers an ergonomic shape, which makes it easy for the rider to get on and off. The frame is specially designed to minimize all the vibrations and noise from the drive system, the right wheelbase for a high speed and a pleasurable ride on both paved and unpaved roads.
The ENVO Battery powering the Flex is a lightweight, down tube mounting Li-Ion pack in a stylish thin ABS case with an auto-connect socket and security lock. The battery is removable and can reach a range of up to 100 km per charge on pedal assist level 1. The battery can be charged on or off the bike frame using the little portable CC-CV smart Li-Ion battery charger. The ENVO Battery is an A-grade branded Li-Ion battery, comprising of LG or Panasonic Li-Ion cells and a BMS that avoids battery from overcharging, overloading and other hazardous activities, thereby increasing both cyclic and calendar life of the battery. Battery cells have been selected for best operating in freezing temperatures. Furthermore, Flex comes with a dual battery option that doubles your range.
The Flex is equipped with an advanced pedal-assist sensor with an optimized torque emulation software. The advanced torque emulating Pedal Assist Sensor (PAS) signals the controller to run the motor between 5 levels of pedal assist, providing a boost to your pedalling depending on the level of assistance you select while riding. The Flex is equipped with an on-demand thumb throttle that gives you an extra boost which activates the motor proportionally to the twist no matter you pedal or not to give you a fully electric ride in case you cannot pedal or need an instant acceleration or uphill push.
