Lectric XP4: Everything You Need to Know

The Lectric XP4 is the fourth XP folding hub bike, still $999 for the 500W / 500Wh and $1,299 for the 750W / 840Wh long-range. That price has not moved since the first XP. What moved: a torque sensor (PWR+), Star Union 602 hydraulics on 180 mm × 2.3 mm rotors, a 3.5-inch color TFT you can pull off the bar, Shimano Altus 8-speed, turn signals, a redesigned single-beam that swallows a bigger pack, and UL 2849 / UL 2271 on the system. It ships as a Class 2 (throttle to 20 mph) and the display will run Class 1 or Class 3 where that is legal. It is a 20×3-inch folding commuter, 69–72 lb with the battery, not a Brompton and not a Light Bee. Forbes (31 Aug 2026), Men’s Journal (May 2026 Gear of the Year), WIRED (Nov 2025, 8/10 on the 750), BikeRide (93/100 on the 500W), and Electric Bike Report’s standardized loops are the published pile. Outdoor Gear Lab’s March 2026 500W range number is the one Lectric ads will not quote.

Two motors, two tanks, one fold

Both bikes are rear hub motors (Lectric M24 ‘Stealth’) in a 20-inch fat-tire folder. The 500W is the value; Ebike Escape’s September 2025 500W review called it the sweet spot for most riders. The 750 is the hill and cargo bike: Forbes rode it to a true Class 3 28 mph in Turbo PAS in Portland; throttle still dies at 20. That is the federal-shaped Class 2/3 hybrid a lot of 2026 direct-sale bikes use — throttle to 20, assist to 28. Men’s Journal: the extra $300 also buys a suspension seatpost and a larger headlight. Payload is 330 lb including a 150 lb rack. If you and the groceries are that number, buy the 750. If you are a 10-mile flat commute, the 500W’s 500Wh and $999 are the product.

The fold is the point and the limit. Unfolded about 66×18.5×47 in. Folded about 37×17×29 in. BikeMag (July 2026): Velcro strap; lift it wrong and the frame swings into your shin. It is a 70 lb origami brick, not a 34 lb Brompton P Line. The folding article on this desk is still the size-class split: XP4 lives in a garage and a trunk; Brompton lives on a train. Step-through and step-over, 4′10″–6′3″ claimed. Front 50 mm coil, 20×3 with Slime in the tubes from the factory. IPX5, not a pressure washer.

The range the ads will not print

Lectric’s 50 / 85 is Eco on the flat with a light rider. Named tests, 500W pack: Electric Bike Report — 30.2 miles on the highest PAS, 55.1 on the lowest. BikeRide — PAS 5 (Boost) 24.69 miles, PAS 3 32.76 miles at ~18 mph. BikeMag — 34 mixed, maybe 40–45 Eco on the flat. Outdoor Gear Lab (18 March 2026) — 19.1 miles with ~900 ft of climbing, throttle near 20 on the flats, under 10 mph on hills, walking speed at 10% SOC. That 19.1 is why OGL ranked the 500W 16th of 19 on range (4.8/10) and 71 overall. The 750’s 840Wh is the fix: OGL 36.7 miles; EBR about 30–35 on Turbo; WIRED’s heavier tester still cleared 50 on a first charge in Chapel Hill hills. Men’s Journal aggressive mix ~30. EBikeReviewLab (Jan 2026): 44 miles mixed PAS 2–4 on the 500W (88% of the 50-mile claim); 37.2 throttle-only on the 750 with 2,000 ft of climbing.

Watt-hours are the tank (volts × amp-hours). 48×10.4 ≈ 500Wh. 48×17.5 = 840Wh. OGL’s point on the 500W: a ~1,090W peak from a 500Wh pack is why the last 20% falls on its face. Charge time about 5.5–9 hours depending on brick and pack (BikeRide). Bring the battery inside in the cold; maintenance still wants 40–80% storage. Charge with the matched brick — that is the UL 2849 kit, not a random 54.6V Amazon charger.

Class, paths, and the menu

Ships Class 2: thumb throttle to 20, PAS to 20 unless you open Class 3. The 750’s party trick, per Forbes, is PAS to 28 in Turbo. That is legal only where Class 3 is legal — helmet and 16+ in California, not on most Class I paths, not at NYC’s 15 mph street cap, not at 28 on the Tampa Riverwalk (15) or Pinellas (20). AB 1774 in California bans speed-override dongles. Lectric’s own class menu is the manufacturer toggle, not a derestrict file. Throttle off = Class 1 for path managers who care. A throttle you never twist can still be Class 2 on the hangtag. Read the sticker, then the sign.

UL 2849 (system) and UL 2271 (pack) are why this bike still sells into NYC and California 2026 rules. One-year limited warranty is the cheap-bike tell — Aventon and Bosch dealer bikes run longer. IPX5 is rain, not a hose. Lights after dark are a bicycle rule in every state; the XP4’s 90-lumen headlight plus turn-signal tail is the kit, not a helmet substitute. CPSC 16 CFR 1203 on your head anyway.

What it is not — and who should buy which

It is not a mid-drive. Hills at OGL’s 10 mph on the 500W are the hub-without-gears problem; you still have an 8-speed, so use it. It is not cargo in the Tern HSD/GSD sense — 150 lb on a folding rack is groceries, not two kids. It is not an e-moto. Do not controller-map a 48V 500Wh folder; the mods we like on this bike are tires at 45 psi (OGL’s range test pressure), a second lock (10–15% of $999), and leaving the 750W hangtag alone.

The torque sensor is the ride change from XP 3.0. Cadence hubs lurch; PWR+ meters how hard you push, which is why BikeRide’s 500W XP4 climbed faster than the 3.0 on the same 55 Nm motor. Hydraulics on 180×2.3 mm rotors are why WIRED said ‘great brakes’ and BikeRide expected 16–17 ft stops — better than the mechanical cables the early XPs wore. The removable 3.5-inch TFT is the theft and rain play: take the screen, leave a brick. Assembly is the 9/10 OGL loved: 90% built in the box. The kickstand is the 1/10 WIRED hated. Fold strap is Velcro. None of that is a deal-breaker at $999. It is the list you know before the truck shows up.

Who should not buy it: a fourth-floor walk-up with no elevator (70 lb, every day). A rider who needed a 27.5-inch commuter that never folds — that is a Level 4. A kid-hauler — that is a Tern. Anyone who thought ‘folding’ meant 35 lb. Anyone who will run Class 3 on a 15 mph path and argue with a ranger. Lectric’s own accessory catalog (racks, bags, kid seat on the 150 lb rack) is how people overload the fold hinge; stay inside the printed kilo ratings. One-year warranty: register it, keep the box photo, do not wait for year two.

Versus XP 3.0: BikeRide’s 500W XP4 cut ~40 seconds off the 3.0 on their small hill and 22 seconds on the medium, same 500W/55 Nm on paper, torque sensor and gearing in practice. Versus Aventon Level 4 REC: Level 4 is a 27.5-inch non-folding commuter with a bigger tested loop on Electric Bike Report; XP4 is the trunk bike. Versus Aventure 3: fat-tire non-fold, more trail. Versus Ride1Up Portola / Vorsa in OGL’s chart: those beat the 500W on range; the 750 is the Lectric that belongs in that fight. Versus Lectric XP Lite 2: smaller 375Wh pack, 52 lb, Class 1/2 only — the Lite is the lighter, shorter-range sibling, not this bike. Do not cross-shop them on a 20-mile commute. Buy the tank you will actually empty.

Buy the 500W if the commute is flat, under 15 miles round trip, and $999 is the budget — EBR’s 55 Eco miles is a week of that. Buy the 750 if you have hills, a loaded rack, or you actually want Class 3 PAS in a state that allows it. Buy a Brompton if you carry the bike. Buy a Level 4 if you never fold. Do not buy an XP4 as a Sur-Ron alternative. Assembly is the 5% OGL loved (9/10): it shows up 90% built. Kickstand is the part WIRED called an afterthought. Two locks. PSI on the sidewall. Class set to the path you are on today. That is everything you need to know, plus the 19.1-mile OGL loop so you do not believe 85. If you only remember one line: $999, ~70 lb, torque-sensor hub, tested range in the 20s–30s when you wring it, 50-plus only in Eco on the flat, Class 2 unless you change the menu, UL sticker on the pack. The folder America actually buys, with the numbers the ads skip. Full fold-vs-Brompton sizing still lives in the small-spaces folding piece. Come here for the XP4 spec sheet and the tested miles. Then set the class to the sign in front of you and ride. That is the bike.
