14 reasons not to buy

Reviewers complain the throttle only activates once pedaling at 3mph.
There is a delay of up to five revolutions for pedal assist to activate, and assistance cuts out abruptly after a one-second lag.
In a throttle-only range test, the reviewer covers just 12.7 miles.
A reviewer’s battery dies when the display still shows two of four bars remaining.
The M20X struggles on hills in testing.
As with most motorcycle-style e-bikes, experts say pedaling is uncomfortable.
With a 33” seat height, riders at the low end of the height range (5’3” to 6’6”) may not fit.
A reviewer reports ghost pedaling at 10mph due to the limited 6-speed gearing.
Experts find the mechanical disc brakes squeaky and the motor noisy.
The payload capacity of 220lb is well below average.
Reviewers notice that the top speed drops to between 13 and 15mph when battery reaches 50%.
One tester complains that the seat is hard and uncomfortable.
Experts note play in the suspension fork, and the adjustments don’t work.
The M20X’s poor IPX4 water resistance means it can only withstand light splashes, so it shouldn't be ridden in the rain.

Bottom line

The Macfox M20X is a budget motorcycle-style e-bike with a 500W motor and 499Wh battery. Reviewers compliment the bike's looks, maneuverability, responsive throttle, and grippy fat tires. The bike must be in motion for the throttle to activate, but pedaling is uncomfortable, and pedal assist activation is severely lagging. Other complaints include meager battery range and motor power, low payload capacity, poor water resistance, an inaccurate battery meter, and a bouncy suspension fork. With so many issues, it's hard to recommend the Macfox M20X, even at this price.

I’m not sure what I think about the bike. It is pretty affordable… The speed is just a killer for me. It’s got to go faster for me to get excited.

2023 Macfox M20X Review

… [if] you just need something to cruise around, head on down to the store, [and] pick up something, this would do pretty well in that scenario. I don’t see this being something that’s used for long-distance commutes.
