      Pedro Lyons
      Nice Tires

      Good build quality. It feels sturdy and the battery lasts longer then I thought. Does good on the trails in Florida.

      What I needed

      It's good all around bike. It does it all. Folds, goes off road, powerful. It's bee good so far!

      Jan Clarke
      Off Road and Folding

      The bike is great. The fat tires and power motor is all you need. It's a heavier foldable, but I don't mind because it can tackle any terrain. Over all it's a fun bike.
