Is the Spacewalk M6 worth it at $646.99?

At $646.99 at Walmart as of November 4, 2026, it is a low price for a full-suspension fat-tire e-bike with a 750W peak motor. The catch is the heavy steel frame and small 16-inch wheels, so it suits short trips and rough paths more than fast commuting.

How fast and how far can it go?

The motor peaks at 750W and the top speed is 21.6 mph. The 48V 15.6Ah battery is rated for up to 56 miles, which assumes low assist; expect well under that at full throttle or on hills.

Spacewalk lists a rider height range of 5'1" to 6'2" and a 27.56-inch seat height. Taller or heavier riders should note the 264 lb payload limit.

What comes in the box?

The listing includes the charger, headlight, horn and kickstand, plus an LCD display. Assembly is required.

How does it compare with a 20-inch fat-tire e-bike?

The M6's 16-inch wheels make it more compact and easier to store, but 20-inch bikes roll over obstacles better and feel more stable at speed. Choose the M6 for size and price, a 20-inch model for ride quality.

Only two stores list it new, so discounts are rare. Watch for seasonal sales at Walmart, and check the price history before buying.

Our take on the Spacewalk M6 Off road Electric Bike for Teens/Adults

The Spacewalk M6 is a compact fat-tire e-bike with a peak 750W hub motor, a 48V 15.6Ah battery and full front and rear suspension. Its 16x4.0-inch tires and steel frame give it a small footprint and a 264 lb payload, and it is rated for riders from 5'1" to 6'2". The best new price is $646.99 at Walmart as of November 4, 2026, and only two stores list it new, so there is little price competition to shop around.
