FRAME

The Flex is built with a solid, lightweight, foldable and unisex hydro-formed aluminum alloy frame suitable for people from 4’11’’ all the way to 6’5” rider. It is capable of supporting up to 400lbs 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.

BATTERY PACK

The ENVO Battery powering the Flex Urban is super lightweight, down tube mounting Li-Ion pack in a stylish thin ABS case with an auto-connect socket, a charge indicator, security lock. The battery is removable and can reach a range of up to 100Km / 62mph 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. Flex comes with a dual battery option, allowing you to go twice as far in your travels. Dual batteries on Flex Urban gives you 920Wh of battery capacity, allowing you to travel up to 200km / 125miles on a single charge.

E-ASSIST SYSTEM

The ENVO 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 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.

GEARED MOTOR HUB

ENVO FLEX Urban is equipped with a sealed, powerful, upkeep free, geared hub motor that offers 500W power and 60Nm 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 20,000 Km (12,500 miles) of maintenance-free ride.

ADJUSTABLE STEM

The FLEX Urban comes with an adjustable telescopic handlebar, this lets the rider do the ergonomic fine tuning allowing them to choose efficient pedaling position.

ELECTRIC BIKE TIRES

Flex Urban comes with 20inch urban 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.

ELECTRIC BIKE DISK BRAKE

Top of the line mechanical disk brakes equipped with electric cut-off sensors provide more safety to the bike as well as the rider.

TRANSMISSION SYSTEM

Well-engineered 52T chain ring and 8 speed 11-32 teeth cassette transmission help you overcome up to 25% grade when climbing a hill on gear 1 or 40km/h (25mph) speed on gear 8 with gentle peddling.

REAR RACK

ENVO Flex comes with a specially designed sturdy rear rack with rating of 150 lbs weight and capable of fitting two child seats (longer version). The rear rack comes with a cushion (Just on short racks) allowing a second adult to ride on the ebike.

Love it!

So far I love this bike! I’m new to ebiking and this one is comfortable, smooth, easy to operate and adjust. I plan on getting it tuned up yearly by a professional but so far it’s great. The only thing I would change is when it’s in 1st gear the chain rubs on the tire, so I won’t use 1st if I can help it.

For the price it isn't bad, definitely the cheapest option I found for a cargo ebike that carries kids. It does the job.

I haul two kids with it using Polisport seats attached to the large rack - gets them to and from daycare, barely. I live in Nelson, BC - we have a ton of steep grades and the battery can sometimes struggle. I would definitely recommend going with a 48V bike if you have a bunch of hills.

I like that both a front and back rack, as well as foot pegs, were included as part of the purchase price. ENVO also seems to have a ton of dealers in Canada, so service options should be available if it comes to that. We were also heavily considering an Aventon Abound. Chose ENVO because it was quite a bit cheaper, but you always get what you pay for :).

Setup was simple enough, they have an online video on youtube.

My main issues with the bike are:

- Mechanical brakes are stock. For a bike that's supposed to carry kids, this is a truly headscratching choice from the design team. You absolutely have to spec hydraulic brakes on a cargo bike. Even the D35 has hydraulic brakes.
- Battery range is nowhere near what they advertise! I have never achieved more than 30km before running out of juice, and when you get to around 30% charge remaining the bike starts to struggle with power up hills.
- Fender stay was broken when shipped. Customer service was fairly responsive and sent a new part right away, props to that. They've been fairly responsive on the whole.
- Chain rubs against tire in 2 lowest gears. I have a strip all the way around the tire where you can see the rub. This was a setup issue from factory that I fixed.
- Fat tires. Not a huge fan of the 3" tires on the bike. I emailed and asked if I can decrease the tire size, they stated only a 3" tire would fit. That's unfortunate.
- External battery looks a bit silly compared to bikes with integrated.
- No child containment systed (ie. MonkeyBars). We have two seats for now but my 5 year old will be too big for them next year. This would be a huge seller for ENVO so not sure why they don't have a simple containment system. When I asked ENVO they said one might be in development.

Even with the mixed experience on this bike I am still considering other ENVO Bikes like the D50. It's just tough to find independent reviews of ENVO bikes to help when researching bikes. Hope this helps future customers.

Il est comme un neuf. J’ai installé des guidon pliant sur la tige de ma selle. Ainsi je peux me promener avec ma fille assise sur le coussin arrière. Je le recommande fortement. Il roule très bien
