3.5/5 Buy from Heybike

We initially found it difficult to tell the Heybike Mars 2.0 apart from the Ranger S, but this comparable option has plenty of advantages in its folding frame.

Heybike asked us to review the updated Mars 2.0 shortly after reviewing the Ranger S. Despite the different frame types, there are many similarities between the models.

At first glance, it seems that the Mars 2.0 should be considered a more advanced version of the Ranger S. However, it lacks some of the features that allow it to be a direct parallel model.

The overall length, height and tire size are virtually identical both folded and unfolded, so we approach the Mars 2.0 review by making comparisons between the two. We position this e-bike as a less feature-rich alternative to the Ranger S.

We prefer the Ranger S for a few reasons, but that doesn't mean the Mars 2.0 is a bad option; it's just different. There's a lot to like about this e-bike, especially when it's on sale.

Heybike Mars 2.0 e-bike review &mdash ; design

Mars 2.0 has a flip-over frame with a high seat and handlebars. The entire frame can be folded in half for storage, and the rear post has a perforated plate.

Obvious buttons feature light and horn controls.

The retro design of the Heybike controls makes a comeback in Mars 2.0. We're glad to see obvious horn and light buttons instead of complex touchscreens or touchpad controls.

The 7-speed shifter and Shimano throttle are located on the right, while the horn, light and pedal controls are on the left. The LCD display is in the center and shows speed, pedal assist level and more.

7-speed shifter and throttle on the right side

The battery is located under the seat in the rear half of the bike, which changes the weight distribution across the frame. It doesn't make any difference while riding, but the much lighter front end makes it less awkward to fold and close.

There is even a handle under the seat, which makes lifting the folded device much easier.

The seat has an interesting design with a spring that reduces shock from impacts. There is also a lever that allows you to move the seat to the side when installing or removing the battery.

The battery is located under the rear seat.

The Heybike Mars 2 weighs 75 pounds and measures 67 by 25 by 49 inches. When folded, it measures 37.4 by 21.7 by 27.95 inches.

The wheels are 20 inches in diameter and 4 inches thick. It has mechanical front suspension and mechanical brakes.

Assembly and maintenance

Heybike Mars 2.0 arrived mostly assembled. We had to attach the front wheel, fenders, pedals and seat.

Folding bikes have more moving parts than regular ones. Keep this in mind when assembling so that the cables are not pinched or stretched during use.

As always, maintenance should be performed at weekly intervals to check for underlying wheel damage. Brake pads and shift levers should be checked monthly, and cable integrity and transmission should be checked every six months by a professional.

Heybike Mars 2.0 e-bike review &mdash ; Features

Heybike Mars 2.0 features a 750W motor and a top speed of 28mph. It has a maximum range of 45 miles and the maximum load capacity of the bike is 330 pounds.

Mars 2.0 is equipped with a 750W motor

The 750W motor can reach a peak power of 1200W, which is what the Ranger S is capable of. We didn't have enough before this feature, but it's what makes these two Heybike models so great when climbing uphill.

Thanks to the 1200 W peak load, the driver will need much less effort when going uphill. However, this feature should be used with caution as it means the battery will drain much faster. Climb too many steep hills and the battery will drain well before 45 miles.

Speaking of the battery, it charges in six to seven hours using the included 2A charger. This is slow charging compared to some bikes we've tested, but that's not a big deal since the bike is usually charges overnight.

The pedal assist on the Heybike is not a torque sensor, so the bike will push the rider to the desired speed range. There are six levels from 0 to 5.

The headlight is a simple unit with no turn signals

The headlight and tail light system is much less complex than the Ranger S. The small headlight does not have an automatic function and is turned on by a button.

The tail lights come on when you press the brakes. However, Mars 2.0 does not have built-in turn signals.

Heybike App

To be honest, we didn't bother with the Heybike app for Mars 2.0 review. Sure, we hooked up the bike to make sure it was up to date and tuned, but that's about it.

Heybike (left) didn't track very well compared to Fitness (right) when we tested the Ranger S

Interestingly, the app said not about Mars 2.0, and about Ranger S. connection. I couldn't fix this detail in the settings either.

The application is not useless. It can be used to track rides using map and bike data, but Apple Fitness proves to be more accurate and reliable.

Configuration options in the app include setting speed limits for different levels of pedal assist and enabling touchless unlocking.

Riding the Heybike Mars 2.0 e-bike

We not big fans of walking bikes. Getting in and out requires a little more thought and coordination than we'd like.

Transition frame – more classic design

When you're on the bike, the experience is very similar to the Ranger S, minus the extra features. The Mars 2.0 has manual brakes and suspension, but lacks turn signals and auto-lighting features. But it rides great with its fat tires.

The additional seat spring was a nice addition. It was more convenient than jumping on a hard, motionless surface.

The large and heavy e-bike maneuvers well on both asphalt and gravel, and the thick tires and suspension make it easy to handle rough terrain. Overall we liked the ride and handling.

Fold the Mars 2.0 for easy transport or storage

Because the e-bike is foldable, we were able to easily fit it into our Honda HR-V, the same as the Ranger S. It didn't leave much room to maneuver, but it stored safely .

Heybike included a front basket with the Mars 2.0 kit so we could test it, but it wasn't suitable for our use case. Because the basket was attached to the main frame and not the steering wheel, it protruded outwards and did not fit into our car when folded.

An interesting addition is the perforated rear pillar panel

The rear pillar has slots for attaching things like bag straps. There are holes on the sides of the rack that resemble pegboards, allowing you to attach additional connections — the perfect place to hang a bike lock.

The 750W motor, with a peak output of 1200W, got us up our regular test hill without any effort. We were surprised at how effectively he lifted us up.

A good intermediate option in terms of price and function

It's strange to think that price is the deciding factor for the Mars 2.0 versus the Ranger S, since both have an ESRP of $1,499. However, Mars 2.0 is sold at a huge discount, but more on that at the end.

Heybike Mars 2.0 is a decent option

We're happy with Heybike's folding frame options. These are easy to store, powerful bikes with great design.

Clients will need to choose whether to prioritize the end-to-end or transition frame and then move forward. We prefer the more fully featured Ranger S, but we're unhappy with the Mars 2.0.

Overall, Heybike has proven itself to be a reliable brand that offers durable bikes. If only their app was a little better — Honestly, that's the problem with most e-bikes.

Rating: 3.5 out of 5

The Mars 2.0 e-bike is a good option but lacks the features of the Ranger S despite being listed same price. It's unclear why the Mars 2.0 has different brakes, headlights and other components despite being almost the same size and weight.

Those looking for a good folding step bike will find a good option here. The rating would be 4 out of 5 if it included all the features of the Ranger S.
