Infinitely Portable

Foldable, storable, powerful, comfortable, and ready for anything! Making this electric bike foldable means that it'll fit in the trunk of a car or easily into an RV, even a helicopter!! So it can go anywhere with you.

500W Geared Motor

Provides superior power, whether it's speeding over the worst hill on your commute or blazing through on gravel and sand.


The design of the bent handle is more in line with the physiological structure of the human body.

3-level Pedal Assistance

Pure electric mode, Intelligent 3 level pedal assist mode and manual mode (pedaling) mean that you will be ready for all kinds of conditions and terrains.

Dual Front Light & Braking indicator

Ride safe using the bright headlight with a unique LED circle that lightens up your way while also making you be seen visibly.

20" x 4.0 Resistant Fat Tires

Mars features 4-inches wide fat tires. The large surface area of contact with the ground offers superior traction, stability, and a smoother ride compared to conventional bikes.

Shimano 7-Speed

Customize your ride performance with Shimano 7-Speed. A wider range of gearing at your disposal mean more torque for treacherous uphill climb and maintain pedal authority at top speed.

Loving this bike

Hit 100 miles on this bike. It makes biking accessible while being as out of shape as I am. The ability to adjust the handle bars through out a ride as you get tired is great and very easy to do.
I have a small SUV that a regular bike could not fit in. With the ability to fold this bike I can easily fit 2!
The saddlebags are 100% worth getting. I tend to always need extra snacks or need another layer of warmth, and the saddle bags have been able to fit everything with no issues.
The mirrors have turned out to be the biggest necessity on any trail we have been on, due to others not really knowing to warn that they are passing.
Keep in mind that you should double check wverything is tightened before you go riding. The bounce in the car can sometimes be enough to loosen the bolts. So definitely keep the allen wrenches on hand

Michael Spann

I ride this to and from work everyday so I appreciate the ease of use. I mostly ride in low which is a gentle assist when you start pedaling so I get my daily exercise, if I ever feel the need to stop for an errand on the way I can do medium or high assist which kicks in by pedaling or via the throttle.

Claudia Martin

I would recommend the Mars as a first time ebike owners choice. It's affordable and very good quality. we are happy with this purchase.

Jeff Russ

We bought two bikes.Now we go everywhere cruising at around 23 mph. For a 10 miles round trip at full throttle the battery only lost one bar (with several to go) on the battery charge level meter. Mars seems reliable and had a comfortable ride, my wife loves her black friend.

John E

Really nice bike, seems great so far!
