Summary of Reviews

We have read all expert and user reviews on the Heybike Mars 2.0. In summary, this is what cyclists think.

12 reasons to buy

  • The Mars 2.0 has fenders, integrated lights with brake activation, and a kickstand.
  • The spacious rear rack is rated for 120lb.
  • Reviewers savor the “comfortable” ride over bumpy surfaces.
  • The Heybike app offers convenient PAS speed customization and security features such as an inactivity lock and proximity on/off.
  • Folding the Mars 2.0 is simple and fast, say reviewers.
  • In real-world testing, the Mars 2.0 gets close to the stated battery range of 45 miles.
  • Testers and owners say the Mars 2.0 is fast and exciting, with “excellent” hill-climbing ability.
  • Heybike states fitment of 5'3" to 6'1". Riders from 5’1” to 6’2” agree that it’s "comfortable."
  • Experts appreciate the “responsive,” “controlled” braking, even on slippery surfaces.
  • Testers relish the CHAOYANG tires’ grip on varied terrains and the bike’s “sure-footed” ride on loose dirt and gravel.
  • The Mars 2.0 has a suspension seatpost and a 65mm suspension fork with lockout and adjustable preload.
  • The display is easy to read in bright light and through polarized lenses, according to testers.

4 reasons not to buy

  • Experts say the powerful, abrupt acceleration can be scary or dangerous for unprepared riders.
  • The rack’s slotted sides don’t comply with aftermarket standards and Heybike offers no dedicated accessories, reducing the utility of the rack.
  • At 75lb, the bike’s heft makes lifting or carrying it hard work.
  • One tester struggles with a “very erratic” battery meter.

Bottom line

Heybike’s Mars 2.0 updates the highly-rated Mars folding electric bike with a higher 28mph top speed and more powerful 750W motor but an increased weight of 75lb. The “exciting” speeds and “comfortable” ride impress reviewers and owners, who also praise the battery range of 30 to 45 miles. The easily folded bike fits a good range of riders. However, the motor kicks in with a worryingly strong surge, and the rack’s design is more gimmicky than practical. Despite these shortcomings, the overall opinion is that the Mars 2.0 offers an “excellent” mix of quality, performance, and affordability.
