Is full suspension worth it on a fat-tire e-bike?

Yes if you ride broken pavement, gravel or trails. The rear shock and fat tires together absorb far more than a rigid frame. On smooth roads you pay for it in weight.

The 6-speed drivetrain lets you shift to easier gears and add pedal effort on climbs. Fat tires and a heavy steel frame still make long steep climbs hard work.

How does it compare with a 26-inch fat-tire e-bike?

The 20-inch wheels are more compact and quicker to steer but roll over roots and curbs less easily. A 26-inch model rides smoother on rough ground but takes more space.

Is it good for commuting?

It works for short commutes over rough roads, and hydraulic brakes help in traffic. The weight makes stairs and tight storage awkward.

What should I check before buying?

Confirm the battery range and motor wattage for your route, and check the bike's weight rating against your own. Also check whether a rack and lights are included.
