ENVO offers this bike in two builds: the basic Stax and the equipped Stax Pro.
In a range test of the regular Stax, a 6’3”, 220lb reviewer gets 30.8 miles at an average speed of 12.8mph.
Testers praise the powerful motor, which handles steep inclines and cruises comfortably at 20mph in PAS 5.
At 42lb, the Stax is lightweight for an e-bike. ENVO doesn't provide a weight for the Stax Pro.
Reviewers say it's easy to pedal the Stax without motor assistance.
The Stax's handling is nimble and responsive, according to an expert.
One reviewer likes the balanced weight of the seatpost-integrated battery.
The Shimano BR-MT200 hydraulic disc brakes provide ample stopping power in testing.
Testers say the compact display and integrated controls are easy to use.
The Stax ships as Class 1 (20mph) but can be unlocked to 25mph (Class 3) in the display.
Experts and owners compliment the sleek finish and integration.
Owners appreciate the easy assembly and support from ENVO when they have questions.

8 reasons not to buy

The battery’s charging port between the saddle and seatpost is tricky to access.
Owners and reviewers dislike the exposed, bulky battery cable that enters the frame beneath the bottom bracket.
The Stax's stated height range is 5’5” to 6’5”, but a 6’ reviewer finds it slightly too small, and a 5’6” owner says it's too tall.
One reviewer finds the motor noisy.
The Stax webpage lacks multiple specifications. These must be found in the user manual.
The Stax is only available in one size and color.
Two buyers receive bikes with damaged inner tubes.
The standard Stax build has an externally powered taillight.

Bottom line

The ENVO Stax is a commuter e-bike with a 500W hub motor and 460.8Wh seatpost battery. The base build has 700c x 40mm tires; the Stax Pro has 27.5" x 1.95" tires, an adjustable stem, a mono-shock suspension fork, a throttle, a kickstand, and commuter accessories. Only the base build is tested by experts. The sleek, integrated design, low weight, comfort, and smooth ride impress. Some like the seatpost battery; others don't. Complaints are mostly minor, but the limited height range reduces the bike's appeal. However, if it fits, reviewers and owners consider the Stax a good option for city riders.

ENVO Stax Is a $2,000 Almost-Perfect E-Bike That Looks Like a Regular Bike

Level 1 expert

It is not the cheapest e-bike in this category, but I think it has the best value due to its form factor, weight, and efficiency.

If I was in that 5’8” to 5’10” range, I would enjoy this bike a little bit more, and if I was looking for a solid commuter that was efficient, comfortable, smooth… this would definitely get up into my queue.
