Overview

The Mars 2.5 is a folding fat-tire e-bike on a step-over frame, sitting between the outgoing Mars 2.0 and the full-suspension Mars 3.0 in Heybike's lineup. It is a straightforward, lower-cost way into a folding fat-tire e-bike, without the extra features of either bike positioned around it in the range.

The motor is rated 750 W with a 1,000 W peak, running through fat tires mounted on the folding step-over frame, and the bike is available in a single color, Black.

25–36 mi

Every row says whose number it is. Hills, headwind, tire pressure, rider weight and cold all move them, and throttle riding moves them most. Plan a commute around the low end of the row you recognize, not the number on the box.

Based on 0.6 kWh a charge and a 25 mile planning range, against a car at 25 mpg. Fuel only, so no insurance, parking, tires or depreciation are counted on the car's side. The real gap is wider than this.

Q&A

Questions riders actually ask

The Mars 2.5 is a folding fat-tire bike on a step-over frame, positioned between the outgoing Mars 2.0 and the full-suspension Mars 3.0. It's a straightforward, no-frills way into a folding fat-tire bike.
No, the Mars 2.5 doesn't have the Mars 3.0's full suspension. It sits between the older Mars 2.0 and the Mars 3.0 as the simplest, most affordable folding fat-tire option in the lineup.
It ships free to the lower 48 states, with a required signature and no delivery to PO boxes. Most orders ship within 1 to 4 business days.
You have 14 days from delivery to return it, minus a 25% restocking fee and the return label cost. Defective units are replaced free. The battery is final sale.
