Lectric XP4 vs Heybike Saturn (2026): Folding vs Moped Power

Most buyers comparing the Lectric XP4 vs Heybike Saturn should pick the XP4: it is the budget option, it folds, it is far lighter, and reviewers say it pedals like a real bike. The Saturn is the better choice if you want moped-style power, a plush full-suspension ride and room for a passenger, and you have somewhere to keep a very heavy bike.

These two e-bikes share a 330 lbs max load capacity, 180mm hydraulic disc brakes and a claimed 28 mph top speed. Beyond that they are built for different riders. One is a practical folding commuter and the other is a powerful cruiser.

Weight, folding and storage

This is the clearest split. The XP4 folds to 37"L x 17"W x 29"H, which Lectric pitches at car, RV and apartment storage. The 500W model weighs 62 lb without its 7 lb battery, or 69 lb in total. The XP4 750 uses a 9 lb battery on the same 62 lb frame.

The Saturn doesn't fold. Heybike lists it at 103 lb with a single battery and 115 lb with the dual-battery setup. Reviewers call it very heavy and awkward to lift or store.

Reviewers do add a caveat for the XP4: it is still heavy for a folding bike and hard to carry. Even so, it is much easier to move around than the Saturn. If you need to lift the bike into a trunk, up steps or into a small space, the XP4 wins this round easily.

Power and hill climbing

Here the Saturn comes out ahead. It has a 1000W (sustained), 1800W (peak) hub motor with 95 N·m of torque, and reviewers praise its strong acceleration and climbing. Its stock top speed is 28 MPH, and Heybike says it can be unlocked to 40 MPH for private use. Reviewers do note that the front end feels light near that unlocked top speed.

The XP4 500W has a 500W rear hub motor, 1092W peak and 55Nm of torque. Reviewers say this version struggles on steeper hills, and some find the throttle touchy and the motor somewhat noisy. The XP4 750 is the answer for hilly routes: Lectric lists it at 750W, 1310W peak and 85Nm. The XP4's 8-speed Shimano Altus drivetrain (11-32T freewheel) also helps on hills and at Class 3 speeds.

If you ride steep terrain and want the most punch, the Saturn is the stronger machine. The XP4 has less peak power than the Saturn, and its 750W version is the one that covers hilly routes.

Ride comfort and rough ground

The Saturn is built for comfort. It has full suspension (140 mm front, 55 mm rear travel), 20"x4.0" fat tires, a long bench seat and an upright posture. Reviewers praise the cushy, planted ride. Some found the suspension stiff or the seat less comfortable, so it isn't flawless.

The XP4 rolls on 20" x 3" puncture-resistant tires with Slime. Reviewers say its basic front fork is out of its depth on rough terrain. For bumpy roads, this round goes to the Saturn.

The Saturn also has an edge for carrying a second person. It has passenger footpegs and a long bench seat, which reviewers say suit carrying a passenger. The XP4's integrated rack is rated 150 lb, but Lectric doesn't describe a passenger setup.

Pedaling feel and everyday features

The XP4 has a torque sensor, and reviewers praise the smooth, natural pedal assist. It also comes with a rack, fenders, lights, turn signals and a detachable 3.5" color TFT display with a USB-C port. Assembly is tool-free. Lectric lists a rider height range of 4'10" - 6'3".

The Saturn comes with a rear rack, fenders, mirrors, turn signals and a TFT display, plus Heybike app connectivity. Its brakes are two-piston hydraulic discs with motor cutoff, and its frame is UL 2849 certified. Heybike lists water resistance as IPX5 on the spec sheet, while a reseller page says IPX6. Lectric doesn't list a water-resistance rating for the XP4. Reviewers note the Saturn feels like a moped, so pedaling adds little at speed.

If you want an e-bike you actually pedal, the XP4 is the better fit. If you would rather twist and go, the Saturn's moped feel won't bother you.

Range and charging

Lectric claims up to 50 miles from the 500W model's 48V, 10.4Ah (500Wh) battery, and up to 85 miles from the XP4 750's 48V, 17.5Ah, 840Wh pack. The battery is removable and has an auxiliary charge port, so it can charge on the bike. The included 2A charger takes 4-6 hours, and a 5A fast charger is sold separately.

Heybike's manufacturer claim for the Saturn is 30-50 Miles on a single 52V 18.4Ah (956.8Wh) battery and 55-90 Miles on the dual setup (2 x 52V 18.4Ah, 1913.6Wh). Charging time is 6.5h per battery.

The Saturn's dual-battery option offers the longest claimed range, but it adds weight, and both makers' figures are claims. The XP4 750 is claimed at up to 85 miles, against 55-90 Miles for the Saturn's dual-battery setup.

What experts say

Electric Bike Report scored the XP4 (500W) 4.8 out of 5. The XP4 is also recommended in 4 expert buying guides. Reviewers praise the smooth torque-sensor assist, the easy folding storage, the strong-feeling hydraulic brakes and the included rack, fenders, lights, turn signals and color display. Common criticisms are that it is still heavy for a folding bike, that the 500W version struggles on steeper hills, that the front fork is basic for rough terrain, and that the throttle can feel touchy.

RiderGuide scored the Saturn 90 out of 100. Reviewers praise its strong acceleration and climbing, its cushy full-suspension ride, the long-range dual-battery option and its passenger-friendly seat. The main criticisms are weight (103 lb or more), a moped-like feel that makes pedaling add little at speed, a light front end near unlocked top speed, and some reports of stiff suspension or a less comfortable seat.

These are single scores on different scales, so they aren't a like-for-like ranking. Both bikes score well from the reviews cited here, and the real difference is the type of bike each one is.

Choose Lectric XP4 if…

Choose the XP4 if you need an e-bike that folds, fits in a car, RV or apartment, and feels like a real bike to pedal. It is the budget option and the much lighter one, and it comes with a rack, fenders, lights, turn signals and a color display. If your routes are hilly, look at the 750W version.

Choose Heybike Saturn if…

Choose the Saturn if you want moped-style power, a plush full-suspension ride and the option of a dual-battery setup for long claimed range. It also suits riders who want to carry a passenger. You need to be comfortable with a bike that doesn't fold and weighs 103 lb or more, and it is the premium-priced option.

The verdict

For most people the Lectric XP4 is the better all-round choice. It is lighter, it folds, it is easier to store and it pedals naturally, all at the lower price tier. The Heybike Saturn is the one to buy if power, comfort and passenger capacity matter more than weight and portability.
