A folding fat tire e-bike for beach trips, gravel roads, and weekend getaways where you need the bike to pack small between rides.
The Heybike Mars 3.0 uses the same 750W motor as the Ranger 3.0 Pro, with 95 Nm of torque and a 624Wh removable battery, and is built around 20 x 4 inch puncture resistant fat tires for sand, gravel, and light trail use, with up to 65 miles of range. The frame, handlebars, and pedals fold down for storage in a car, RV, or closet.
Why this model
- 20 x 4 inch puncture resistant fat tires add traction and comfort on sand, gravel, and light trails.
- 95 Nm of torque handles hills and soft surfaces without straining the motor.
- 624Wh removable battery gives up to 65 miles of range, and pulls out to charge separately from the bike.
- Folds at the frame, handlebars, and pedals for storage in a trunk, RV, or closet.
- UL 2849 (bike) and UL 2271 (battery) certification are independent safety testing you can verify.

Fit, power and setup
The battery pulls out and charges on a standard household outlet, and the bike folds at the frame, handlebars, and pedals for storage without tools. It ships mostly assembled from an authorized Heybike dealer, and the IPX6 rated electrical system holds up to rain, splashes, and beach spray.
Good to know
- 95 Nm of torque, against 80 Nm on the Ranger 3.0 Pro, makes this better suited to sand and gravel trips than the Ranger's city focused build.
- The removable battery is handy for RV and camping trips where you want to charge indoors overnight.
- This still folds down small enough for a car trunk despite the fat tires.
- Wear a helmet. Check your state and local e-bike rules.
Check your state and local regulations before riding on public roads, since rules for high power electric bikes vary by state. Not suitable for riders under the manufacturer's recommended age.
