Lectric XP4 Review (2026): 500 W or 750, Range and Fit

The Lectric XP4 in both versions, read on Lectric's own pages on October 5, 2026: its range computed by speed, hill, load and cold, its fit by your height, the 28 mph setting and the law, and the folders we sell beside it.

By Milad Ghobadibeygvand, BScN (Western University, 2014), Redtail eBikes. Verified October 5, 2026. Part of our Lectric eBikes profile, alongside the Lectric return policy guide and every Lectric dealer by state.

The Lectric XP4 on paper: both versions

The XP4 comes in two power versions on one 6000 series aluminum frame, and each in a high-step and a step-thru. Lectric's XP4 page and its XP4 750 page print the rows below, read on October 5, 2026. Lectric introduced the bike in a post dated May 6, 2025.

Both versions ride on 20 × 3 inch puncture-resistant tires with Slime sealant, stop on "602 hydraulic brakes paired with 180mm rotors (2.3mm thick)", and shift an 11-32 tooth, 8-speed freewheel through a Shimano Altus derailleur, all in Lectric's spec tab.

The front fork is a suspension fork you can "adjust the tension or lock it out". Lectric calls the tires "perfect for mixed terrains", and its XP4 manual (page 6) says the bike is "NOT INTENDED for mountain bicycle use including any kind of jumping or downhill mountain biking". Whether a trail allows e-bikes at all varies by "state, municipality, and in some cases trail", in Lectric's words (below).

Lectric lists a rider height of 4'10" to 6'3" and a 330 lb payload for both frames. The step-thru's standover is 19 inches and the high-step's 24, per the step-thru page's size guide.

XP4 or XP4 750: which one to buy

Buy the XP4 750 if you climb, weigh more than about 220 lb with your load, or ride farther than 20 miles at a time; buy the 500 W XP4 for flat trips under 20 miles. The $300 between them buys 250 more watts of rated power, 30 more newton-meters of torque and 340 more watt-hours of battery, on the same 62 lb frame with a battery 2 lb heavier.

The battery is the larger difference. At 15 mph on the throttle, our model gives the XP4 29 miles and the XP4 750 50 miles, 180 lb aboard on level pavement at 77 °F. On an 8% grade at 10 mph, the 750 still holds the speed on the throttle with 220 lb aboard; in the model, the 500 W XP4's motor cannot hold it at that weight.

The 750 also charges slower on the included charger: 7 to 9 hours against 4 to 6, per Lectric's charging rows. Lectric's 5-amp charger, $149 on its listings, cuts that to "as little as 3.5 hours" on the 750 and "as little as 2 hours" on the XP4.

On October 5, 2026 Lectric's listings also added free accessories: five worth $365 at Lectric's own prices with the 750, and a $79 rack with the XP4 (what comes on the bike).

How far the XP4 goes: range by speed, hill, load and cold

At 15 mph on the throttle, the XP4 goes about 29 miles and the XP4 750 about 50, with a 180 lb rider on level pavement at 77 °F. Lectric states "up to 50 miles" and "up to 85 miles", and its XP4 manual (page 41) gives the test behind them: flat ground, few stops, no cargo, little wind, about 75 °F, a 20 mph top speed, a rider of about 180 lb and tires at 35 psi.

The manual does not say how much the rider pedaled. The tables below compute the rides that test leaves out: other speeds, hills, loads and temperatures.

Find your ride in three steps:

1. Find your usual speed in the speed table.
2. If you pedal, read the effort table; if you climb, the hills table.
3. Adjust for your weight and the season in the load and cold tables.

Every range figure here is computed from the physics and Lectric's published specifications, and each states its conditions. The formula is worked through at the end, and Limitations names every assumption.

Does speed cut the XP4's range? Miles at each speed

Yes, sharply: from 10 to 20 mph on the throttle, the XP4's range falls from 42 to 20 miles and the 750's from 71 to 35. The power it takes to push the air grows with the cube of your speed, so each extra mile per hour costs more battery than the last. The figures are for a 180 lb rider on level pavement at 77 °F with no wind.

For a margin, keep 25% of the pack in reserve: the XP4 then gives 22 miles at 15 mph and the 750 38. The throttle stops at 20 mph, per Lectric's help center, so faster riding is pedal assist.

Do gears or pedaling save battery on the XP4?

Pedaling does: adding an easy 75 W of your own at 15 mph stretches the XP4 from 29 to 48 miles and the 750 from 50 to 80. At a steady speed, every watt you pedal is a watt the motor does not draw from the battery.

The XP4's torque sensor is "designed to manage power output based on the rider’s pedaling effort", per Lectric's spec tab, and Lectric's manual (page 41) lists "Ride at a lower PAS level" first among its tips for range. A gear changes your cadence and leaves the hub motor's speed where it was.

Both columns are for 180 lb aboard on level pavement at 77 °F. For scale, 75 W alone would carry the XP4 at about 9.1 mph on the flat with the motor off, and 150 W at about 13.2 mph, in the same model.

How much battery does a climb cost?

Hills split the two versions: at 10 mph on an 8% grade with 180 lb aboard at 77 °F, a full XP4 battery lasts about 4 miles on the throttle and the 750's about 9. Both need about 480 W at the wheel, near the 500 W motor's rating, and in the model that motor turns less of the battery's energy into climbing: the XP4 spends 124 Wh a mile against the 750's 91.

At 12 mph on an 8% grade the 500 W XP4 cannot hold the speed on its throttle in the model; with you pedaling a steady 150 W it holds 12 mph at 73.5 Wh a mile. Every 1,000 feet of climbing at 4% and 10 mph costs the XP4 about 184 Wh on the throttle and the 750 about 153.

Lectric's manual (page 42) warns that "Using the throttle to go uphill at a slow speed will put the maximum strain on the drive system", and its range tips say to "Use lower PAS levels and pedal when climbing hills".

How much does a heavier rider or a full rack cost?

Each 50 lb aboard costs the XP4 about 2 to 3 miles at 15 mph on the flat, and on steep climbs it decides whether the motor can hold the speed. Lectric rates both versions for 330 lb, rider and cargo together, and the rack for 150 lb of that. The flat figures are at 15 mph on the throttle; the climb at 10 mph on 8%; all at 77 °F.

"Past the model's motor" means the comparable motor in the model cannot hold 10 mph on that grade at that weight on the throttle: pedal, or ride slower. Limitations item 2 explains why the model's motor can understate Lectric's.

How much range does the cold take?

At freezing the XP4 loses about a fifth of its range: 23 miles at 15 mph on the throttle instead of 29, and the 750 40 instead of 50. The cells hold less usable energy when cold, in McMaster University's LG cell data, and the bracketed figures show the spread across the cell studies read.

Lectric names no cell maker for the XP4 on its listings or in its manual, so the model uses a representative cell, LG's 18650HG2.

Lectric's XP4 manual asks you to charge the battery only between 32 °F and 113 °F (page 52), to run it between 32 °F and 104 °F for its best service life (page 53), and to "Store the battery indoors in a dry space" (page 55). The 14 °F row is a ride below Lectric's own range: keep the pack indoors until you leave.

Do the tires and your posture cost range?

The tire's rolling resistance moves the XP4's range by about 7 miles at 15 mph, from 27 to 34, across the fat tires on Bicycle Rolling Resistance's drum. Lectric says its custom tread "has less rolling resistance" and prints no figure, so the model brackets it: the median of ten fat-bike tires the lab measured, 26 × 4.0 inch at 12 psi, with the lightest and heaviest beside it.

Lectric ran its range test with the tires at 35 psi, and before every ride its manual's checklist (page 9) has you check "that the front and rear tire pressure is within the recommended pressure range printed on the tire sidewall". Riding tucked lowers the drag area below the upright 0.64 m² the model uses, from Tengattini and Bigazzi, 2018, and adds a little range at 20 mph.

Lectric's 50 and 85 miles, as a steady ride

Lectric's "up to 50 miles" asks the XP4 to spend 10.0 Wh a mile, which the model reaches at 7.2 mph on the throttle or about 15 mph with you pedaling an easy 75 W. The 750's "up to 85 miles" needs 9.9 Wh a mile: 6.8 mph on the throttle, or 14.6 mph with the same easy pedaling. Both are for a 180 lb rider on level pavement at 77 °F.

Those conditions are close to the test in Lectric's manual: a rider of about 180 lb on flat ground at about 75 °F.

The claims are within reach of a rider who pedals. On the throttle alone at a commuting 15 mph, plan on 29 and 50 miles, or 22 and 38 with a quarter kept in reserve.

The range formula, worked through

Range is the battery's energy divided by what each mile costs, and each mile's cost is the power to roll, to push the air and to climb, divided by your speed and by the motor's and the battery's losses. The power at the rear wheel comes from Martin and colleagues' 1998 model:

P = v × [ m × g × (Crr × cos θ + sin θ) + ½ × ρ × CdA × v² ]

Here v is your speed, m the mass of rider, load and bike, g gravity and θ the slope; Crr is the tires' rolling resistance, ρ the air's density and CdA the drag area you show the wind.

One ride, worked through: the 500 W XP4 at 15 mph on the flat on the throttle, 180 lb aboard.

1. Mass. 180 lb of rider and 69 lb of bike make 112.9 kg.
2. Rolling. Speed × mass × gravity × rolling resistance. 15 mph is 6.7056 m/s, so 6.7056 × 112.9 kg × 9.81 × 0.01054 = 78.3 W.
3. Air. ½ × air density × drag area × speed cubed: ½ × 1.184 × 0.64 × 6.7056³ = 114.2 W.
4. At the wheel. 78.3 W + 114.2 W = 192.5 W.
5. The motor. Lectric publishes its watts and torque but no efficiency, so the model takes the Bafang RM G0H0 hub at Bafang's 80% floor, rebased to 48 V, 500 W and Lectric's 28 mph. At this speed it runs at 78.3% and draws 192.5 ÷ 0.783 = 245.9 W.
6. The battery. At this current the pack delivers 96.0% of what its cells give, so the cells give 245.9 ÷ 0.960 = 256.1 W.
7. Per mile. 256.1 W ÷ 15 mph = 17.1 Wh a mile.
8. Range. Lectric's 500 Wh is 48 V × 10.4 Ah = 499.2 Wh, and 499.2 ÷ 17.1 = 29.2 miles on a full pack; keep a quarter in reserve and plan on 21.9.

The same arithmetic on the 750's 71 lb and 840 Wh gives 16.7 Wh a mile and 50.3 miles. That is less per mile than the lighter XP4 needs, because at this load the 750's motor runs at 79.6% and its larger pack delivers 96.7%. Lectric prints no wheel diameter, so the model uses 21.53 inches, measured for the same 20 × 3.0 tire on another maker's drawing (Limitations item 3).

Will the XP4 fit you? Frame, saddle and standover

Lectric sizes both XP4 frames for riders from 4'10" to 6'3", in one size, and its seat post sets the saddle from 29.5 to 42 inches above the ground. Pick the frame by how you get on: the step-thru's frame is 19 inches high where you step over, the high-step's 24, per Lectric's size guide.

To find your fit:

1. Check your height against Lectric's 4'10" to 6'3".
2. Measure your inseam (barefoot, floor to crotch) and find your saddle height in the saddle table.
3. Set it with the heel check on the first ride.

How high should my saddle go?

For a typical 5'8" rider, the saddle's top sits about 35.6 inches from the pedal axle with the crank in line with the seat tube; at 6'2" about 39.3 inches. That is 109% of your inseam, the one saddle method with lab measurements of economy behind it, as Peveler and colleagues (2005) note, applied to the US Army's ANSUR II survey of 6,068 bodies.

The inseam column spans the middle 90% of the survey's riders at each height; the three saddle columns are for the rider in the middle. If your inseam sits elsewhere, multiply it by 1.09.

Lectric's 29.5 to 42 inches is measured from the ground, and turning it into a distance from the pedal needs the bottom bracket's height and the crank's length, which Lectric does not print. Measure from the pedal at home instead: it needs neither.

Can I put my feet down at a stop?

Yes on both frames for every height from 5'0" up: the typical inseam at 5'0" is 28.4 inches, above the high-step's 24 and the step-thru's 19. The table counts, out of 100 riders of each height in ANSUR II, how many clear each frame barefoot.

At 4'10", Lectric's lowest listed height, the survey holds too few bodies at that height for a figure; the step-thru's 19 inches leaves the most room there.

How upright will I sit?

Upright, in Lectric's words: its zero-degree stem "shortens the handlebar reach" for "an upright cruising position". Its size guide puts the grips 45 to 48 inches above the ground, adjustable, and lists a "Handlebar Reach" of 15 to 18 inches without saying where that is measured from. Lectric prints no seat angle or bottom-bracket height either, so the lean for your body cannot be computed from its figures.

How much weight rests on my wrists?

The load on your hands depends on where the grips sit relative to the saddle, and Lectric does not publish that, so it is not computed here. What Lectric prints is the grips' height above the ground, 45 to 48 inches, on a telescoping stem.

For a yardstick, Carahalios (2015) measured 10 racing cyclists on an ergometer with their hands on road-bike brake hoods and found 15% of their body weight on the stem. The XP4 puts your hands somewhere else, a place Lectric's figures do not locate, so that 15% is a yardstick for a road bike only.

How do I set the saddle when it arrives?

Use the heel check in Lectric's manual (page 20): sit on the saddle, "Place one heel on a pedal" and turn the crank until that pedal is at the bottom, in line with the seat tube. Your leg should be straight there; if your hips rock to reach the pedal, the saddle is too high. With the ball of your foot on the pedal, the knee then bends slightly.

In Peveler and colleagues' comparison of 19 cyclists, this heel method put the knee in the recommended 25 to 35 degrees for 70% of them, "the greatest percent of participants" of the methods compared. Tighten the clamp, ride a block, and adjust a quarter inch at a time.

The fit arithmetic

Saddle top to pedal axle = 1.09 × your inseam, with the crank in line with the seat tube. For a 5'8" rider with the survey's median inseam at that height, 32.64 inches (32.6 in the standover table): 1.09 × 32.64 = 35.6 inches. Measured from the crank axle instead, LeMond's 88.3% gives 28.8 inches.

The two right-hand columns of the saddle table run from 106%, the bottom of the range Ferrer-Roca and colleagues (2012) call recommended, to 110.4%, the top of the range their own equation proposes.

How fast the XP4 goes, its class, and where you may ride

The XP4 ships as a Class 2 bike with its throttle held to 20 mph; unlocked to its Class 3 setting, pedal assist runs to 28 mph and the throttle stays at 20. Lectric's help center says "All Lectric eBikes ship as a class 2 electric bike", that "the XP4, XPedition2, XPeak2, and XPress2 can be unlocked to achieve class 3 settings", and that "It is just a simple change of the settings on the display".

The same article gives the throttle's limit a reason, "due to federal eBike laws, the throttle will remain limited to 20mph regardless", and a warning: "You must check your local regulations before unlocking your bike as laws vary by state, municipality, and in some cases trail." The top speeds Lectric lists for the XP4 are 28 mph on pedal assist and 20 on the throttle.

The federal definition Lectric points to is in 15 U.S.C. § 2085(b): "a two- or three-wheeled vehicle with fully operable pedals and an electric motor of less than 750 watts (1 h.p.), whose maximum speed on a paved level surface, when powered solely by such a motor while ridden by an operator who weighs 170 pounds, is less than 20 mph".

Where the 28 mph setting may go is state and local law. California's Vehicle Code § 312.5 defines a class 3 bike as one "that ceases to provide assistance when the bicycle reaches the speed of 28 miles per hour, and equipped with a speedometer".

Section 21213 says "A person under 16 years of age shall not operate a class 3 electric bicycle" and requires a helmet of every class 3 rider and passenger on a street, bikeway or public path or trail. Under § 21207.5(b), the local authority or public agency over an equestrian, hiking or recreational trail "may prohibit, by ordinance, the operation of an electric bicycle or any class of electric bicycle on that trail".

Lectric sets its own floor for every setting: its manual says the XP4 "is not designed to be ridden by a child under the age of 16" (page 51).

Folding, weight and carrying

The XP4 folds to 37 × 17 × 29 inches, length by width by height, and weighs 62 lb with the battery out, the heaviest piece you lift. The battery adds 7 lb on the XP4 and 9 lb on the 750, per Lectric's size guide. Unfolded it is 66 inches long and 47 high.

Lectric's spec tab describes "a foldable hinge at both the handlebar stem and frame", quick-release pedals and a side kickstand, and says you can "remove the pedals and the seat post in seconds" for transport. Measure your trunk or closet against 37 × 17 × 29 inches before you order.

Take the battery out before you lift. The key is for that alone: "Keys are needed to remove the battery from the bike frame only," in Lectric's words, and a button starts the bike.

Charging, water and what comes on the bike

Charge it on the bike or off: an auxiliary port near the bottom bracket takes the charger with the battery in place, and the included 2-amp charger fills the XP4 in 4 to 6 hours and the 750 in 7 to 9. Both figures are Lectric's; its manual gives a wider "approximately 6-10 hours if the battery is mostly empty" without naming the pack (page 55), so plan an overnight charge either way.

On water, Lectric's help center says "The XP4, XP Trike2, and XPress2 are IP-X5 rated", and also: "The electrical components on the bike are not waterproof. The warranty for all Lectric eBikes does not cover water damage."

Lectric's manual (page 9) says the bike "can withstand light rain and small splashes, but it is not designed to be subjected to inclement weather, extremely heavy showers, or submersion in water", and that on wet roads "it will take longer to brake and to stop."

What comes on the bike, from Lectric's spec tab:

• A thumb throttle on the left, below the bar.
• A torque sensor and five riding modes: Eco, Tour, Sport, Sport+ and Turbo.
• A color TFT display on a detachable mount, with a USB-C port.
• Keyless riding: a button turns it on.
• A 90-lumen headlamp with amber side lights, a brake-activated rear light and turn signals.
• A rear rack rated for 150 lb, which takes a child seat through Lectric's LevelUp Rack, or Lectric's Buddy Seat for a child who has outgrown one, each sold separately.
• Fenders and a suspension fork with a lockout.

Cruise control works on the throttle: in Lectric's manual (page 46) you "Throttle to your desired cruise speed then hold the minus button", and either brake lever cancels it. Neither the listings nor the manual mentions a horn; Lectric sells a bell separately, $24 on the XP4 750's listing.

For a passenger, the manual (page 49) holds the rack to 150 lb in all and says "A passenger must always keep both feet on the foot pegs when the bike is in motion". The listing warns that on the Buddy Seat "feet can get caught in the wheel spokes while riding, resulting in serious injury or death".

On October 5, 2026 the XP4 750's listings added five accessories free: the LevelUp Rack ($79), a phone mount ($39), a bike lock ($59), the Elite Headlight ($99) and a suspension seat post ($89), $365 at Lectric's own prices. The XP4's listings added the LevelUp Rack free.

XP4 or XP 3.0: what changed

The first change Lectric lists is the torque sensor: the XP 3.0 used a cadence sensor. Lectric's own comparison lists the rows below, in its words. The motor keeps 500 W and 55 Nm; the peak rises from 1000 W to 1092 W and the stated range from 45 to 50 miles on the same 10.4 Ah battery.

The XP 3.0 no longer has a product page on Lectric's store, as our Lectric profile records, and its two user manuals stay on Lectric's manuals page for owners.

Certificates and recalls

Lectric states the XP4 is certified to UL 2849 and its battery to UL 2271, and that "a US-based bicycle testing lab" put it through ISO 4210. Its spec tab reads: "The Lectric XP4 is certified to UL 2849. Additionally, the XP4's lithium-ion battery is certified to UL 2271." These are Lectric's statements on its page; ask Lectric for the certificate if your building or insurer requires it.

The CPSC's recall data, read across all 10,027 records on October 4, 2026, holds one Lectric recall: recall 23-789 of September 7, 2023, for mechanical disc brake calipers on XP 3.0 models. The XP4 is not among the models it names, and Lectric introduced the XP4 in 2025.

Three folding bikes we sell that match it

If the XP4's shape suits you but you want a brand we sell, three folders match it: the Samebike CY20 Pro at $599, the Eunorau META20 at $1,699 and the VTUVIA SX20 at $1,299. Each price and figure below was read at its maker and on our store on October 5, 2026; each range figure uses the XP4's physics, at 15 mph on the throttle with 180 lb aboard at 77 °F.

Buying one of these from us

We sell other makers' e-bikes, not Lectric's, and we have no showroom. Our US support answers fit questions in writing before you pay, every e-bike ships free within the contiguous United States, and if one will not power on, will not charge or shows an error code, the claim comes to us and we coordinate the repair or replacement.

Know our return window before you order, because it is narrower than Lectric's: our refund policy takes a bike back only unopened in its factory-sealed box, when you ask within 72 hours of delivery, less a 15% restocking fee and the return shipping. How buying works here walks through an order, and every e-bike we carry is on one page.

Green flags, and who the XP4 fits

Five things in the XP4's favor, each beside the rider who should read another bike instead, and where to read it.

Frequently asked questions

Is the Lectric XP4 worth it?

For flat trips under 20 miles, yes at $999: it brings a torque sensor, hydraulic brakes, eight gears and a 28 mph setting to a folder. For hills or longer rides, the XP4 750 at $1,299 is the version our model favors, with 50 miles at 15 mph on the throttle against 29.

Which Lectric XP4 should I buy?

The XP4 750 if you climb, carry a passenger or weigh over about 220 lb with your load; the 500 W XP4 for flat town riding. Both share the frame, the 330 lb payload and the 28 mph setting.

How fast does the Lectric XP4 go?

It ships as a Class 2 bike with the throttle held to 20 mph, and unlocks in the display to 28 mph on pedal assist; the throttle stays at 20 mph, per Lectric's help center. Check your state's class 3 rules before unlocking it.

What class is the Lectric XP4?

Class 2 as shipped: "All Lectric eBikes ship as a class 2 electric bike," in Lectric's help center. Its listing says the five modes run it "as a Class 1, 2, or 3 eBike", with a footnote that reads "Where permitted by state law." The 28 mph setting is Class 3.

How far can the Lectric XP4 go on one charge?

Lectric states up to 50 miles for the XP4 and 85 for the XP4 750, tested on flat ground with a rider of about 180 lb at about 75 °F, per its manual. On the throttle at 15 mph with a 180 lb rider on level pavement at 77 °F, our model gives 29 and 50 miles; pedaling an easy 75 W raises that to 48 and 80.

How heavy is the Lectric XP4?

62 lb without the battery, 69 lb with the XP4's 7 lb battery and 71 lb with the 750's 9 lb battery.

What is the Lectric XP4's weight limit?

330 lb, rider and cargo together, on both versions; the rear rack carries up to 150 lb of that.

How long does the Lectric XP4 take to charge?

4 to 6 hours for the XP4 and 7 to 9 for the XP4 750 on the included 2-amp charger, per Lectric's listings, whose manual gives 6 to 10 hours for a mostly empty battery. Lectric's 5-amp charger, $149, cuts that to as little as 2 and 3.5 hours.

Is the Lectric XP4 waterproof?

No. Lectric rates it IP-X5 and says its electrical components "are not waterproof" and that its warranty "does not cover water damage". Its manual says it "can withstand light rain and small splashes" but not "inclement weather, extremely heavy showers, or submersion in water", and that wet roads take longer to stop on.

Does the Lectric XP4 have cruise control?

Yes, on the throttle. Lectric's XP4 manual says to throttle to the speed you want and hold the minus button; either brake lever cancels it.

Does the Lectric XP4 have a throttle?

Yes, a thumb throttle on the left below the bar, limited to 20 mph.

Does the Lectric XP4 have a torque sensor?

Yes. Lectric describes "proprietary in-house-designed torque sensor programming"; the XP 3.0 before it used a cadence sensor.

Does the Lectric XP4 have suspension?

A suspension fork in front: Lectric says you can "adjust the tension or lock it out". Its spec tab lists no rear suspension.

Does the Lectric XP4 have turn signals?

Yes: a brake-activated rear light with turn signals, and a 90-lumen headlamp with amber side lights, in Lectric's spec tab.

Does the Lectric XP4 have a removable battery?

Yes. The key removes it; you can also charge it on the bike through the port near the bottom bracket.

What size Lectric XP4 do I need?

One size covers Lectric's 4'10" to 6'3"; pick the step-thru for a 19-inch standover or the high-step for 24. For the median 5'8" rider in the Army's survey, with a 32.64-inch inseam, set the saddle top about 35.6 inches from the pedal axle: 109% of the inseam. Lectric's manual adds its own floor: the XP4 is not designed for a rider under 16.

What is the difference between the Lectric XP4 and the XP 3.0?

A torque sensor in place of the XP 3.0's cadence sensor, an 8-speed Altus in place of a 7-speed Tourney, keyless riding, turn signals, fast-charger compatibility and a stated range of 50 miles against 45 on the same 10.4 Ah battery, in Lectric's own comparison.

The bottom line

The XP4 is a strong folder at $999, and the XP4 750 is the one to buy if you climb, ride far or carry weight: 50 miles at 15 mph on the throttle in our model against 29. Lectric's 50 and 85 miles are within reach, in our model, for a rider who pedals an easy 75 W at about 15 mph.

If you would rather buy from a brand we sell, the CY20 Pro gives the most battery per dollar of the five bikes on this page, the META20 the most range of our three with room for a second battery, and the SX20 4-inch tires at the 750's price.

Image credit: the cover is a park scene generated on Playcut (playcut.ai) around two of the bikes below, each its maker's own photograph placed whole at one uniform scale, minus Samebike's corner badge and the studio floor shadows; type set in Playcut Brush. The card photos are the makers' own, cropped, scaled and set on white. Nothing is drawn on any bike, and no Lectric photograph is used.

Limitations

Every figure on this page holds under the conditions it states. These are the assumptions and read dates behind them.

1. Lectric's figures are its pages and manual as read on October 5, 2026. Prices, stock and specifications can change; the price on Lectric's store at checkout is the one that counts.
2. The motor in the range model is a comparable. Lectric publishes the watts and torque of its Stealth M24 motor and no efficiency or speed curve, so the model uses a Bafang hub at Bafang's 80% floor and Lectric's rated watts. Its peak of 1,092 W (1,310 W on the 750) is not used, so climbs where the table reads "past the model's motor" may be within the real motor's reach for short stretches.
3. The wheel diameter is borrowed. Lectric prints none; the model uses 21.53 inches, measured for the same 20 × 3.0 tire on Samebike's drawing of the CY20 Pro.
4. The tire's rolling resistance is a bracket. Lectric prints no figure for its custom tread; the model uses the median of ten fat-bike tires measured at 26 × 4.0 inch and 12 psi, not the XP4's 20 × 3.0 at the 35 psi of Lectric's test, and shows the range across them.
5. The cold figures use a representative cell. Lectric names no cell maker for the XP4 on its listings or in its manual; the bracketed figures show the spread across the cell studies read.
6. The fit figures are population figures. They come from the ANSUR II survey of US Army personnel aged 17 to 58, whose bodies differ from any one buyer's; measure your own inseam.
7. The grip position is not published. Lectric prints no seat angle, bottom-bracket height or crank length, and its "Handlebar Reach" of 15 to 18 inches names no starting point, so lean and wrist load are not computed.
8. The saddle formula is a starting point. Shoes, saddle and riding style shift it; the heel check on the first ride is the final word.
9. The range figures are computed from physics and published inputs. Wind, stops, starts and rough surfaces are outside the model, and each costs range.
10. This review expires when Lectric changes the XP4. A new price, battery, motor or class setting on Lectric's listings, a CPSC recall naming the XP4, or a successor model would each age it; we re-read the listings at every touch.
11. We sell e-bikes that compete with Lectric's. The three we name are ours; their figures were read at their makers on October 5, 2026, and your own Shop Pay offer is the one shown at checkout.

Source register

Each source behind this review, the tier it sits in under our sourcing rules and what it supports. Lectric's XP4 listings, help-center articles, posts and manual and the makers' pages of the three bikes we sell were read on October 5, 2026; each reference gives its own date.
