A $999 folding e-bike usually means cutting corners somewhere: a cadence sensor, mechanical brakes, a basic screen. The Lectric XP4 claims to skip most of those cuts. I haven’t ridden it, so this review is built from Lectric’s official XP4 page, rechecked on Oct 27, 2026, and from the folding bikes I have tested.
Should you buy one?
For $999 (as of Oct 27, 2026), Lectric lists a torque sensor, hydraulic brakes, a detachable color display with USB-C, turn signals and a 150 lb rear rack on a bike that folds at both the stem and the frame. Payload is 330 lb. That’s a lot of equipment for the price, and the torque sensor is the part I’d notice most. It reads how hard you push, so the motor feels like stronger legs rather than an on/off shove. The cadence sensor on the Kingbull Literider I tested is more abrupt by comparison.
The trade-off is the battery. Lectric lists 48V and 10.4Ah, which works out to about 499Wh by my math. That’s modest. Lectric rates it for up to 50 miles, but its own footnote says weight, terrain and weather change that, and heavy throttle use will land well below it. Lectric also sells a 750W version and a 17.5Ah battery that it rates for up to 85 miles, both at higher prices. This review covers the 500W base bike.
The XP line has a long track record. Lectric says more than 400,000 riders have bought an XP, and the XP4 is the fourth generation. A big owner base means parts, how-to videos and used accessories are easy to find, which matters on a direct-to-consumer bike you’ll likely maintain yourself.
How it should feel on the road
The base motor is a 500W rear hub with a 1092W peak and 55 Nm of torque. The peak is the short burst for starts and hills. 55 Nm is modest, so steep climbs with cargo will ask more of your legs than the 100 Nm Rad Radster Trail would. Lectric pairs it with a Shimano Altus 8-speed and an 11-32 freewheel, so you have real gears to help on hills rather than relying on the motor alone.
You can set it to Class 1, 2 or 3, including 28 mph pedal assist where that’s legal. Five modes, Eco through Turbo, set how much help you get. The throttle is a thumb trigger under the left grip. Lectric also made the XP4 keyless to ride: you power it on with a button and only need the key to remove the battery.
Stopping looks well covered. The 602 hydraulic brakes need less hand force than cables, and the thick 2.3mm, 180mm rotors shed heat better on long descents. The 20 x 3 in tires come with Slime already installed to seal small punctures, and a front fork with preload adjustment and lockout takes the edge off bumps. There’s no rear suspension, so a suspension seat post is the upgrade I’d look at first if you ride rough pavement.
Folding, fit and the trunk test
The XP4 folds at the frame and the stem, and Lectric lists the folded size at 37 in long, 17 in wide and 29 in tall. The pedals come off without tools, and so does the seat post, which saves more space.
Then there’s the weight. It’s 61 lb without the 7 lb battery, and that’s what you’re lifting when you fold it into a car. The Aventon Sinch I tested fit in my Tesla Model 3’s trunk, but it was tight, and folding it in and out several times a day would have been too much for me. Measure your trunk against Lectric’s folded size before you count on the XP4 doing the same.
Fit is broad for a folder. Lectric lists riders from 4’10” to 6’3”, a 24 in standover and a handlebar that telescopes from 45 to 48 in. The stem is a zero-degree design that shortens the reach and sits you more upright. That’s a cruiser posture, good for errands and paths, less so for fast commuting into a headwind.
Charging, cargo and accessories
The standard 2-amp charger fills the battery in 4 to 6 hours, according to Lectric, and an optional 5-amp fast charger cuts that to about 2 hours. A charge port near the bottom bracket lets you charge with the battery still in the frame, which is handy if you store the bike in a garage with an outlet.
The integrated rack holds 150 lb and has mounting points for Lectric’s accessories. Lectric’s LevelUp Rack bolts on top and has a mounting window for child seats like the Thule Yepp Maxi. For older kids, Lectric sells a Buddy Seat with handlebars and foot pegs, and its own page warns that feet can get caught in the spokes. If you carry a child on any bike, wheel guards and a seat with foot protection matter. Lectric runs bundles often, and on Oct 27, 2026 owner reviews on the page were tagged with an XP4 750 bundle that included a LevelUp Rack, suspension seat post, Elite headlight, lock and phone mount as free extras.
Warranty and certifications
Lectric lists a one-year warranty, half the length of Rad’s current two-year coverage. Lectric says the XP4 is certified to UL 2849 as a complete system, the battery is certified to UL 2271, and the bike passed ISO 4210 testing at a US lab. Those certifications are what I’d look for on any bike that lives inside your home or RV. The display and motor controller are rated IPX5 for water, so riding in rain is fine, but I wouldn’t hose it down.

Pros and cons (from the specs)
Pros: a torque sensor at $999; hydraulic brakes with thick 180mm rotors; a 330 lb payload and 150 lb rack; folds at the frame and stem; Slime from the factory; turn signals and a color display with USB-C; UL 2849 and UL 2271 certified.
Cons: a modest 499Wh battery; 61 lb without the battery is heavy to lift into a trunk; 55 Nm for steep hills; a one-year warranty; the 750W version costs more.
How it compares to bikes I’ve reviewed
The Aventon Sinch is the folding fat tire bike I’ve lived with, and my Aventon Sinch step-through vs Cyrusher XF900 vs Wallke F1 comparison covers the step-through version. The Kingbull Literider is the folding step-through I tested with a cadence sensor and hydraulic brakes. Kingbull listed the Literider 2.0 at $979 (as of Oct 23, 2026) with a 720Wh battery, so it carries more battery for about the same money, while the XP4 counters with the torque sensor. If you want a folder with a bigger battery the Rad RadExpand 5 Plus has a 720Wh pack and a torque sensor, but costs $900 more and tops out at 20 mph. My best folding e-bikes guide has the wider field.
Who it’s for
The XP4 fits riders who need a bike that folds into a car, RV or apartment, budget buyers who still want a torque sensor and hydraulic brakes, and anyone who carries cargo on a rack. Skip it if you need long range from the base battery, ride steep hills with heavy loads, or if lifting about 61 lb is a problem.
Price
$999 for the 500W XP4 on Lectric’s site as of Oct 27, 2026, with a listed compare-at price of $1,146. Lectric runs bundles often, so the included accessories change.
