Heybike Mars Folding Fat Tire E-Bike vs TODIMART JSL039K Foldable Fat Tire E-Bike

The Heybike Mars is the better-rounded folder: dual suspension, a 500W geared motor rated to 20 mph with about 48 miles of range, and a rear rack make it a more comfortable, more practical commuter. The TODIMART JSL039K counters with a bigger 48V 15Ah battery, hydraulic disc brakes and a steel frame rated to 120 kg, but its own listings disagree on top speed and range, and it is heavier at 30 kg. Buy the Mars for mixed pavement and dirt with comfort and cargo; buy the TODIMART if you want hydraulic brakes and a sturdier frame for heavier riders.

  • Choose the Heybike Mars if you want dual suspension, a rear rack and a lighter, more comfortable folder for commuting and light trails.
  • Choose the TODIMART JSL039K if you want hydraulic disc brakes, a higher weight rating and a larger battery, and you mostly ride on roads.

What reviewers say

Heybike Mars Folding Fat Tire E-Bike

Owners of the Mars generally describe it as a solid value fat-tire folder that handles mixed terrain and folds easily, while noting its weight and real-world range falling short of the claimed maximum.

  • WeightCriticisedOwners say the bike is heavy and awkward to lift into a trunk or up stairs.
  • RangeMixedRiders report real range well under the claimed 48 miles, especially on throttle or in cold weather.
  • Fat tiresPraisedThe 4-inch tires and suspension are said to handle gravel, sand and snow confidently.
  • FoldingPraisedThe fold is described as quick and compact enough to fit in a car.

Questions and answers

Which is better for commuting?
The Heybike Mars. Its dual suspension and rear rack suit daily rides and errands, and it is lighter to fold and store. The TODIMART is fine on smooth roads but heavier to handle.
Which has better brakes?
The TODIMART. It uses hydraulic disc brakes, which need less hand force and modulate better than the Mars's mechanical discs, especially in wet weather.
Which lasts longer?
Neither brand publishes a service life. The TODIMART's steel frame and 120 kg rating suggest it tolerates heavier use, while the Mars's geared motor and suspension are common, serviceable parts. Battery care matters more than either frame.
Is the TODIMART worth stepping up to?
If you weigh more, want hydraulic brakes and a bigger battery, yes. If you want comfort, cargo capacity and easier folding, the Mars is the better fit.
Which is better on sand or snow?
Both run 20 x 4.0-inch fat tires. The Mars adds rear suspension, which helps on uneven ground, so it is the more comfortable choice off pavement.
How far can each go on a charge?
Heybike claims about 48 miles for the Mars. TODIMART claims about 50 km, roughly 31 miles. Real range drops with rider weight, hills and throttle use.
