How fast does the Orion AT26 go?

The motor is rated to reach about 20 to 25 mph. That is typical for a 500W hub-drive fat bike and keeps it in the class of bikes that are legal on many paths without a license.

Is the 80-mile range realistic?

Treat 80 miles as a best case at low pedal assist on flat ground. Expect noticeably less with heavy throttle use, hills, cold weather or a loaded rider, since the 48V 16Ah battery is large but not unlimited.

Can it handle sand and snow?

Yes, that is its purpose. The 26 x 4 inch fat tires spread load and grip on sand, snow, mud and gravel, and the 500W motor helps push through soft ground.

What brakes and gearing does it have?

It uses hydraulic disc brakes and a Shimano Altus 9-speed rear derailleur. That combination gives reliable stopping and a wide gear range for climbing.

The bike weighs about 68 lb. Plan for two people or a ramp to load it into a truck or up stairs, and expect it to feel heavier than a standard commuter e-bike.

Riders who need a light, easy-to-carry bike for short city trips will find it heavy and overbuilt. It is aimed at terrain and mixed-surface riding, not fast urban commuting.
