Overview

The Heybike Mars 2.0 is a folding fat-tire commuter e-bike. Choose the 750W motor (1400W peak, 80 Nm) with mechanical disc brakes, or the 1000W motor (1800W peak, 100 Nm) with hydraulic disc brakes, at the same price. It has a 30+ mph top speed, a Shimano 7-speed, a removable 600Wh battery, 20 x 4-inch fat tires, a 65 mm spring fork, an included rear rack and fenders, an LED display with app support, and UL 2849 certification.

The main choice is the motor and brakes. Both versions cost the same, and the 1000W adds more power and hydraulic brakes, so most buyers should pick it. Choose the 750W only if you prefer simple cable-operated brakes.

It suits daily riders on mixed ground (gravel, packed dirt, light snow, sand) with garage or bike-room storage. It weighs 75 lb and folds in about 15 seconds for a trunk, RV bay or garage corner.

StreetRides ships the Heybike Mars 2.0 to riders in Seattle, New York, San Diego, Denver and across the U.S.

Best For

The Mars 2.0 fits you if your routes need fat tires and you can store a 75 lb folding bike at ground level. It suits winter commuters on rough bike paths, rural riders on gravel roads, beach riders on sand, errand-runners using the rear rack, and RV travelers riding at campsites.

It also suits sedan or SUV drivers who fold it for weekend trips, budget fat-tire buyers, and households that want a rough-road bike beside a thin-tire commuter. Heybike recommends riders 5 ft 3 in to 6 ft 1 in.

Skip it if you must carry it up several flights of stairs (the 40 lb Helio F is the light folder), if you ride only smooth bike lanes (the Hybrid is faster on pavement), or if you want the newer Ranger 3 Pro's features.

Performance

The 750W version (1400W peak, 80 Nm) gives comfortable acceleration. The 1000W version (1800W peak, 100 Nm) adds more torque for hills, heavier riders and quick starts. At the same price, the 1000W is the stronger buy.

The 30+ mph top speed is above the 28 mph Class 3 limit, and the 1000W version is above the 750W e-bike motor limit. Use lower speed settings on bike lanes and paths, and check your state rules, since some states treat faster bikes as mopeds. The Shimano 7-speed lets you add your own effort on hills and stretch range.

Hills: the 1000W version handles 8 to 12 percent climbs comfortably with one rider. Long climbs over 15 percent work the motor hard. A hub motor is simpler to maintain than a mid-drive but less efficient on long climbs. A thumb throttle and pedal assist give the usual hybrid riding pattern.

Battery

Heybike rates the 600Wh battery for up to 45 miles with a light rider at low assist on flat ground. A 180 lb rider at mid assist on rolling roads should plan on 22 to 30 miles. Fat tires, hills, cargo, cold and stop-and-go riding cut range further.

Plan your commute around 22 to 28 usable miles with a return reserve.

Charging takes about 6 to 7 hours with the included 2A charger. The removable battery lets you charge inside while the 75 lb bike stays in the garage or bike room. Use only the Heybike charger and follow the U.S. CPSC Micromobility Information Center charging guidance.

Safety & Certification

Heybike lists UL 2849 certification for the Mars 2.0. If you also need separate UL 2271 battery paperwork, ask StreetRides before you order. UL 2849 tests the battery, charger, controller and wiring as one system, which many apartments, condos, dorms and offices ask for.

The 750W version uses mechanical disc brakes, and the 1000W version uses hydraulic disc brakes. Both have LED front and rear lights. Turn signals are not listed, so ask StreetRides if your area requires them.

Wear a fitted bike helmet. At 30+ mph, choose a quality helmet, and note that many states require helmets at Class 3 speeds.

Assembly, Service & Ownership

The box holds the Mars 2.0, the Heybike charger, basic tools and the manual. The bike arrives mostly assembled. You install the handlebars, front wheel and fender, seat, pedals and rear rack. Charge the battery overnight and try each assist level in a parking lot.

First ride: check tire pressure with a gauge (the manual lists the range), squeeze both brake levers (the feel differs by version), practice folding twice, pair the Heybike app and start at the lowest assist level. Save top speed for after an hour or so of riding.

Ongoing: check fat-tire pressure monthly. Lube the chain every 500 miles or after rain. Adjust the shifter cable after 200 miles. Heybike covers the Mars 2.0 with a 2-year warranty from your purchase date, and StreetRides helps you with claims. StreetRides returns: request within 7 days of delivery, 20% restocking fee.

Honest Verdict

The Mars 2.0 packs a lot into a budget folding fat-tire bike. The 750W and 1000W versions cost the same, and the 1000W adds hydraulic brakes, so most buyers should pick it. A 600Wh removable battery, fat tires, a Shimano 7-speed, a spring fork, UL 2849 and an included rack round it out.

The trade-offs are weight and format. At 75 lb, it folds for a car or RV but not for stairs. Plan on 22 to 30 miles of real range, not 45. Heybike has moved on to the Mars 2.5 and 3.0, so this is a prior-generation model.

KEY ADVANTAGES

Why This Ride Stands Out

750W or 1000W at the same price

Both motors cost the same. The 1000W adds hydraulic disc brakes (the 750W has mechanical discs). Most buyers should pick the 1000W.

Folds in 15 seconds for car or RV transport

Folds in three steps to 37.4 x 21.7 x 27.95 inches for a midsize trunk (seats down), RV bay, SUV or garage corner. At 75 lb, it is not for stairs.

20 by 4 fat tires, 7-speed Shimano, and rear rack

Fat tires handle gravel, packed dirt, light snow and sand. The Shimano 7-speed helps on hills, and the included rear rack carries cargo.

Three Heybike commuter formats across two questions: fat-tire or thin-tire, and folding or rigid

Heybike's commuter line splits two ways: fat tires or thin tires, and folding or rigid. The Mars 2.0 and Ranger 3 Pro both fold and run 20 x 4-inch fat tires. The Hybrid is a non-folding commuter with thinner tires. The Mars 2.0 is the budget folder, and the Ranger 3 Pro is the newer flagship.

Why these products

All three are Heybike commuter e-bikes in the StreetRides lineup with UL 2849 certification and a 2-year warranty. The main choices are folding or rigid, fat or thin tires, and price.

StreetRides takeaway

Choose the Mars 2.0 for fat tires on mixed ground at a budget price, if you can store a 75 lb bike at ground level. Choose the Hybrid for paved bike lanes. Choose the Ranger 3 Pro for Heybike's newer flagship folder with hydraulic brakes standard.

Think twice if: Storage is a multi-flight walk-up apartment without ground-floor access (75 lb is not stair-carry friendly), you ride only smooth paved bike lanes (a thinner-tire commuter rides faster and lighter), or you need a sub-45 lb folded carry weight (the Helio F at 40 lb is the lightweight folder answer) View product details	Heybike Hybrid Heybike Hybrid Class 2/3 Electric Commuter Bike Regular price $1,699.00 Sale price $1,699.00 Regular price ~~$2,123.99~~ Unit price per Available Best for: Rigid-frame commuters who want a lighter-weight non-folding e-bike with standard 700c-style geometry on smooth paved routes, and prefer the simpler maintenance and faster rolling of a thinner-tire commuter bike The non-folding commuter sibling.

The Ranger 3 Pro costs more View product details
Motor and road speed How much help will I get on ordinary streets and hills?	750W (1400W peak, 80 Nm) or 1000W (1800W peak, 100 Nm). 30+ mph. Shimano 7-speed. Same price for either motor Evidence Both motors cost the same, and the 1000W adds hydraulic brakes, so most buyers should pick it. 30+ mph is above the 28 mph Class 3 limit, so use lower speed settings where limits apply.	750W rear hub motor (1200W peak). 28 mph top speed. 75 Nm. Class 2/3 switch Evidence The switch matters in states that allow Class 2 on shared paths but keep Class 3 on roads and bike lanes. You can match the rule where you ride.	750W rated rear-hub motor (1400W peak). 28 mph top speed (Class 3) or 20 mph (Class 2 default). Torque sensor plus half-twist throttle Evidence The Ranger 3.0 Pro ships in Class 2 mode by default (20 mph with throttle). To convert to Class 3, the page documents disabling the throttle and unlocking pedal-assist to 28 mph. That conversion process is documented but not as seamless as the Hybrid's software switch. The 750W rated motor fits the federal e-bike wattage cap that most state Class 1/2/3 frameworks use.
Battery and claimed range What route can the battery realistically support?	600Wh removable battery. Up to 45 miles. 6 to 7 hour charge Evidence Heybike rates the 600Wh battery for up to 45 miles with a light rider at low assist on flat ground. A 180 lb rider at mid assist on rolling roads should plan on 22 to 30 miles. Fat tires, hills, cargo, cold and stop-and-go riding cut range further.	864Wh battery, UL 2271. Up to 100 miles, the longest range in Heybike's commuter line Evidence Heybike rates the 864Wh battery for up to 100 miles, tested with a 155 lb rider at the lowest assist level. A 180 to 220 lb commuter at higher assist on rolling roads should plan on 40 to 60 miles. Heavy throttle use cuts that further.	720Wh removable lithium-ion battery. Heybike's range not specified on the spec table. 6 to 8 hour charge time at 54.6V 2A Evidence Heybike does not list a maximum range for the Ranger 3.0 Pro. The 720Wh capacity puts it between the Alpha (680Wh) and Hero (864Wh). Expect 30 to 50 real-world miles depending on terrain, load, and assist level. The 2A charger delivers a 6 to 8 hour full charge.
Weight and portability Can I store and move it?	75 lb (34 kg). Folds to 37.4 x 21.7 x 27.95 inches. 330 lb maximum load. Rear rack included Evidence At 75 lb, the fold is for car trunks, RV bays and garages, not stairs. Two people make loading into a car easier.	6061 aluminum frame. 69 lb. Not foldable Evidence At 69 lb, plan on a hitch carrier rated for at least 80 lb for car transport.	75 lb / 75 lb (34 kg) net weight. Folds to 41.7 by 20.5 by 32.7 inches. Unfolded 69.7 by 25.6 by 52.0 inches. Not a stair-carry product but solves trunk and closet storage Evidence Seventy-five pounds is too heavy for routine stair carrying. The folding mechanism solves vehicle and storage problems differently: the folded footprint fits a sedan trunk, an RV side compartment, an apartment closet, or a shared garage corner. Transport between locations works with a standard hitch carrier rated for the weight.
Ride comfort Will the fit and contact points suit my route?	20 x 4-inch fat tires. 65 mm spring fork. Aluminum folding frame. LED display with app support Evidence Fat tires and a spring fork handle gravel, packed dirt, light snow and rough pavement that 2-inch commuter tires cannot. The app lets you adjust each assist level's speed.	Aluminum commuter frame with hydraulic front fork (100mm travel). 27.5 x 2.4-inch KENDA all-terrain tires. Ergonomic comfort grips and saddle. Shimano Altus 8-speed drivetrain. Torque plus cadence sensor Evidence The Hybrid is shaped for commuting, not for off-road. The 27.5 x 2.4-inch KENDA tire size is narrower than the Hero's 26 x 4-inch fat tire and rolls more efficiently on pavement. Shimano Altus 8-speed is a recognizable component-brand drivetrain at this price. The dual-sensor system (torque + cadence) gives smoother assist than cadence-only setups.	Hydroformed 6061 aluminum alloy frame. Hydraulic front suspension fork. KENDA 20 x 4-inch fat tires with puncture protection. Shimano Altus 8-speed. Torque sensor for smooth pedal assist Evidence The hydroformed aluminum frame plus the included puncture protection on the KENDA tires are quality choices for a folding fat-tire e-bike at this price. The fat tires give all-terrain capability the Hybrid's narrower KENDA 27.5 x 2.4-inch commuter tires do not match, while the folding mechanism solves storage problems the Hero's non-folding eMTB frame cannot.
Braking system What stopping hardware is listed?	Mechanical disc brakes on the 750W. Hydraulic disc brakes on the 1000W, at the same price Evidence This is the key choice. Hydraulic discs stop harder, work better in the wet and need less hand effort on a 75 lb bike. Pick the 750W only if you prefer simple cable brakes.	Premium Tektro hydraulic disc brakes with 180 by 1.9 mm rotors. Appropriate stopping authority for a 28 mph commuter at full load Evidence Tektro is a recognized bicycle brake-component brand. Hydraulic disc actuation gives consistent lever feel and reduces hand fatigue on long commutes. The 180mm rotor size suits the bike's 440 lb maximum load and 28 mph top speed.	Hydraulic disc brakes front and rear. Appropriate stopping authority for the 440 lb maximum total weight and 28 mph top speed Evidence Hydraulic disc brakes match Heybike's standard fitment across the Hero, Hybrid, and Alpha lines. The brake set is sized appropriately for a 75 lb bike with a 440 lb total weight limit.
Electrical safety claim What safety documentation is actually available?	UL 2849 certified. LED display. Heybike app. LED front and rear lights Evidence Heybike lists UL 2849 certification for the Mars 2.0. If you also need separate UL 2271 battery paperwork, ask StreetRides before you order.	UL 2849 bike, UL 2271 battery. Lights with turn signals. LCD color display Evidence Heybike lists UL 2849 certification for the whole bike and UL 2271 for the battery. Turn signals are unusual on a commuter e-bike at this price. Heybike does not list an IP water rating for the Hybrid. Light rain is fine for most commuters, but avoid deep puddles and never pressure-wash it.	UL 2849 certified electrical system. NFC Tap & Go unlocking. TFT color display. Integrated front light with horn. Integrated taillight with brake light and turn signals Evidence UL 2849 certification matches the rest of the enriched Heybike line (Hero, Hybrid, Alpha). NFC Tap & Go is a useful security and convenience feature: tap the included key card to unlock.
Warranty and parts path What happens after the sale?	2-year Heybike warranty Evidence StreetRides helps with warranty claims. Returns: 7 days, 20% restocking fee.	2-year Heybike warranty. Ships in 1 to 2 days from U.S. warehouses Evidence StreetRides helps with warranty claims. Returns: 7 days, 20% restocking fee.	14-day free trial. 2-year standard warranty plus available lifetime warranty option. Ships in 1 to 2 days from U.S. local warehouses Evidence Heybike's warranty framework matches the rest of the line.

Frequently Asked Questions

Buy the 1000W unless you want mechanical brakes. Both cost the same, and the 1000W adds more power (1800W peak vs 1400W, 100 Nm vs 80 Nm) and hydraulic disc brakes.

Pick the 750W if you want simple cable-operated brakes that are easy to service at home, with no fluid bleeding. They need adjusting more often as cables stretch.

Twenty-inch by four-inch fat tires are built for mixed ground. They handle gravel, packed dirt, light snow, sand, rough pavement and curb cuts that 2-inch commuter tires cannot. The trade-off is about 10 to 15 percent less range on pavement.

Fat tires suit winter commuters on rough or snowy paths, beach riders, rural riders on gravel roads and RV travelers at campsites.

If 80 percent of your riding is smooth bike lanes in good weather, the Heybike Hybrid is the better choice.

The Mars 2.0 folds in about 15 seconds to 37.4 x 21.7 x 27.95 inches. That fits a midsize or large sedan trunk with the rear seats down, most SUVs and hatchbacks, and RV bays. It will not fit a small trunk without folding the seats.

At 75 lb, stairs are hard. A fit adult can carry it up one flight with effort, but daily multi-flight carrying is not realistic.

Best storage: a garage, bike room, ground-floor basement or covered patio. For a walk-up apartment, the 40 lb Helio F is the better fit.

Heybike rates the 600Wh battery for up to 45 miles with a light rider at low assist on flat ground. A 180 lb rider at mid assist on rolling roads should plan on 22 to 30 miles. Fat tires, hills, cargo, cold and stop-and-go riding cut range further.

Plan your commute around 22 to 28 usable miles with a return reserve. The removable battery charges inside in about 6 to 7 hours.

Yes. The Mars 2.0 is a prior-generation model, and Heybike now sells the Mars 2.5 and 3.0. Heybike covers the Mars 2.0 with a 2-year warranty from your purchase date, and StreetRides helps you with claims. StreetRides returns: request within 7 days of delivery, 20% restocking fee.

Ask StreetRides about spare parts such as batteries and brake parts if you plan to keep the bike for many years.
