9 reasons not to buy

Heybike markets the Mars 3.0 for off-roading, but experts say the basic suspension can't handle off-road terrains.
One tester reports creaky rear suspension, and another says the battery rattles when riding off-road.
The Mars 3.0 is very heavy for a folding e-bike.
A tester finds that the brakes offer below-average stopping power.
At 36” x 17” x 25” when folded, the Mars 3.0 is bulkier than most 20” fat-tire folding e-bikes.
When unlocked, the throttle reaches a top speed of 32mph, exceeding legal e-bike limits.
The turn signals don’t self-cancel and don't have a display icon.
The 2A charger returns lengthy charge times.
The display is difficult to read through polarized sunglasses.

Bottom line

Heybike’s Mars 3.0 is a full-suspension folding e-bike with fat tires, a 750W motor, and a 624Wh battery. Upgrades over the Mars 2.0 include a torque sensor, hydraulic brakes, increased payload capacity, higher motor torque, and a slightly longer range. Reviewers praise the punchy throttle acceleration, natural pedal assist, performance on climbs, and easy folding. The suspension works well over broken pavement, but it isn’t suitable for off-roading as Heybike claims. The high weight and large folding dimensions limit the usefulness of the folding frame. Nonetheless, reviewers think the Mars 3.0 offers great value.
