It is capable of supporting up to 400lbs (180Kg) of payload and offers a step thru design, 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.

Super Long Range Dual Battery Option

The Flex Trike features a UL-certified battery (48V, 15 A.h) capable of over 100 km on the lowest pedal assist setting and up to 50 km on the highest. For extended range, a dual battery setup (Adding a 48V 17.5A.h battery) offers approximately 220 km per charge, totaling 1560 Wh. These batteries, either LG or Panasonic Li-Ion cells, come with a protective BMS to prevent overcharging and overloading, enhancing their lifespan. Additionally, they are designed to perform efficiently in cold temperatures. Both batteries are UL certified.

Advanced Controller - Bluetooth Connectivity

The ENVO Flex is equipped with a cutting-edge controller, and advance color display capable of bluetooth connectivity to cell-phone. The controller comes 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 pedaling depending on the level of assistance you select while riding. The ENVO Flex is equipped with an on-demand thumb throttle that gives you an extra boost which activates the motor proportionally to the twist, does not matter if you are pedaling, to give you a fully electric ride in case you cannot pedal or need an instant acceleration or uphill push.

Powerful Geared Hub Motor

ENVO FLEX is equipped with a sealed, powerful, upkeep free, geared hub motor that offers up to 1000W of power (Limited to 500W to be street legal) and 80Nm torque. Our motors are designed efficiently and hence are lighter than most powered geared hub motors in Canada, yet they deliver high torque and efficiency. These ENVO motors are developed for over 20,000Km maintenance-free ride.

Tektro Hydraulic Brakes

Fat Cushion Tires

Flex Trike comes with 20x3.0 inch off-road style fat tires. These fat tires are cushion enough to improve ride comfort, dynamic maneuverability, and handling in different terrains. Tires are fat and knobby enough for the best grip on wet cement, asphalt paved, dirt or gravel trails which creates minimum noise and drag for normal urban paved rides.

Leading-edge Differential

Experience a smoother and safer ride with the ENVO Flex Trike, equipped with a differential in its trike axle to ensure both wheels are powered simultaneously, improving traction and stability, enhancing maneuverability, and providing customers with a sage and smooth ride.

A fun way to get around town

I love that the Flex Trike can be transformed into a snow bike or an overland e-bike!

Isabella Wilson

I really like that the new model is coming with a differential. I have an old model that has a front hub motor and I was always thinking it could be the best with rear motors. Well done Envo!

Andy Chang

The Envo Flex Trike fit the bill perfectly.

Maddie Mohammed

I use my Flex Trike for weekend adventures with my wife. We love packing a picnic basket and heading out to explore local parks and trails. The fat tires handle any terrain we throw at them, and the electric assist makes it a breeze going uphill.
