Quick take: The Lectric XP4 750 costs $600 less; the Lectric XP4 750 goes farther on a charge (85 vs 60 mi).

✓The new proprietary torque sensor completely changes how the XP rides - assist ramps up with how hard you pedal instead of the jerky on/off surge of the old XP 3.0's cadence sensor, and it is basically unheard of at this price.
✓The 750W Long-Range model's 840Wh battery is enormous for a $1,299 bike - testers report 50-plus miles in higher assist modes and the 85-mile Eco claim is actually reachable at low assist.
✓The Stealth M24 hub motor is dramatically quieter than previous XPs while making 85Nm of torque, so it climbs real hills without the mosquito whine budget hub motors are known for.
✓Hydraulic disc brakes with 180mm rotors now come standard, a big upgrade over the mechanical calipers on earlier base-model XPs.
✓Integrated turn signals, a brake light, and a 90-lumen headlight make it far more visible in traffic than most sub-$1,500 bikes.
✓The 330-lb payload and 150-lb-rated integrated rear rack let it moonlight as a mini cargo bike, and Lectric's huge accessory ecosystem bolts right on.
✓It ships fully assembled and folds to 37 x 17 x 29 inches, small enough for a car trunk, RV bay, or apartment closet.
✓The bright 3.5-inch detachable color TFT display has a USB-C port for charging your phone and simple Eco-through-Turbo mode labels anyone can understand.

✗At roughly 71 lbs with the long-range battery installed, it is a beast to lift folded into a trunk - owners consistently say folding it is easy but carrying it is not.
✗Lectric only backs it with a 1-year warranty while Aventon, Rad Power, and Velotric all offer 2 years.
✗There is no companion app, GPS tracking, or theft alerts - features rivals at this price are starting to include.
✗One frame size fits most, but riders over about 6'3" report a cramped cockpit even with the telescoping stem maxed out.
✗The 20 x 3-inch small-diameter tires feel twitchy at the unlocked 28 mph top speed compared to full-size 27.5-inch commuters.
✗The base $999 model comes with a much smaller 10.4Ah (499Wh) battery, so real range roughly halves if you skip the Long-Range upgrade.
✗The basic coil suspension fork dives under hard braking and lacks the damping of pricier forks - some owners lock it out entirely.
✗The drivetrain uses a budget 8-speed freewheel and Shimano Altus derailleur, fine for flats but coarse-shifting once the assist tapers off on climbs.

✓The torque sensor transforms the ride versus the old cadence-sensor RadExpand 5 - power arrives smoothly in proportion to your effort instead of surging on a delay.
✓The 720Wh Safe Shield battery is UL 2271 certified and resin-potted for fire safety, and its 60-mile max range is excellent for a folder.
✓The 50mm hydraulic suspension fork plus 4-inch fat tires make it far more comfortable on gravel, boardwalks, and rough pavement than rigid folding rivals.
✓Hydraulic disc brakes with 180mm rotors are a genuine upgrade over the mechanical brakes on cheaper folding fat bikes.
✓The low-slung step-thru frame and adjustable stem fit a huge range of riders, making it a great shared bike for couples or RV guests.
✓It ships with everything included - fenders, 59-lb rack, lights with brake light, and folding pedals - so there is nothing to add for daily use.
✓The 315-lb payload and stout frame handle bigger riders plus loaded panniers without feeling flexy.
✓Rad's two-year warranty and established parts and service network beat the support you get from most folding-bike-only brands.

✗At 72.5 lbs it is punishingly heavy for a folding bike - it folds fine, but lifting it into a trunk or RV compartment usually takes two people.
✗It is Class 2 only with a 20 mph cap and no official way to unlock higher speeds, which frustrates riders used to 28 mph commuters.
✗The 64Nm of torque is modest for a 750W fat bike - steep climbs with a heavy load require dropping to low gears and patience.
✗The 225-lb max rider weight within the payload rating rules out some of the heavier riders the fat-tire category usually attracts.
✗The ~50-lumen headlight is weak for anything beyond being seen - riders who commute in the dark will want a brighter aftermarket light.
✗The folded package is still bulky at 29 x 25 x 41 inches - it fits an SUV or RV bay but overwhelms small car trunks.
✗Fat tires plus a 7-speed drivetrain make unassisted pedaling above 15 mph feel like a workout if the battery dies.
✗At $1,899 it costs several hundred dollars more than Lectric's comparable folding fat bikes, and you are paying partly for the brand and service network.
