Off-Road Adventure
82/100

Fat 20x3.0" tires and dual suspension handle trails well, while peak 1200W motor conquers 30-degree slopes. Limited by 20" wheel size compared to dedicated mountain bikes.

Our Verdict

The ACTBEST Mars electric bike is a really good choice if you want a bike that folds up small but still has lots of power. It has a strong motor that can go 28 miles per hour and climb steep hills without slowing down. You can fold it up to fit in your car trunk or under your desk at work. The bike can carry up to 350 pounds which is more than most bikes, so you can load it up with groceries or camping gear.

This bike works great for people who ride to work or school every day. The battery lasts for 55 miles if you pedal some while riding, which is enough for most people's daily trips. The fat tires help you ride on sand, dirt, or bumpy streets without feeling every little rock. The bike folds up quick when you need to put it away or take it on the bus. It costs less than six hundred dollars which is a good price for all the features you get.

The bike does have some things that could be better. The battery is smaller than fancy expensive bikes, so if you want to ride really far without charging you might want a different model. The frame is made of carbon steel which makes it heavier than bikes made from aluminum. It would be nice if it had a USB port to charge your phone and an app to track your rides. Only three people have written reviews so far, so we don't know much about how it holds up after riding for a long time. But if you need a powerful folding bike that doesn't cost too much money and can carry heavy loads, this is a smart pick.
