Lectric XP4 vs RadExpand 5 Plus: Folding E-Bikes
Last checked Oct 24, 2026 · By EbikePost editors
Short answer
Our pick is the Lectric XP4: lower price, lighter, smaller folded size and a higher rider limit. We don't currently recommend Rad Power Bikes models because of the CPSC battery warning on older Rad batteries and the company's Chapter 11; the RadExpand 5 Plus specs stay here for owners comparing the two.

The short version
This page replaces our earlier Lectric XP 3.0 vs Aventon Sinch.2 comparison: both of those models have been replaced or discontinued (Aventon's site lists the Sinch 2.5 as end-of-life and has no current folding model). The current matchup we can verify is the Lectric XP4 against the Rad RadExpand 5 Plus, two folding e-bikes on 20-inch wheels with wide tires. The XP4 costs about half as much at the maker's price, weighs less and lists a higher weight limit. The RadExpand 5 Plus lists a bigger battery, 4 in tires, a step-thru frame and a 30-day return window. Both are spec-based comparisons; we have not ridden either bike.
Price & value
Maker price on Oct 23, 2026: XP4 $999, RadExpand 5 Plus $1,899. Check the maker's page for the current price. Lectric lists financing at 0% APR or as low as $63 a month with Affirm. Lectric also lists a 750 W, larger-battery option for $300 more on the XP4. Our folding Spec score puts the XP4 ahead (68 against 57), mostly on weight and folded size.
Motor & hills
| XP4 | RadExpand 5 Plus | |
|---|---|---|
| Motor | 500 W rear hub (1,092 W peak) | 750 W rear hub |
| Torque | 55 Nm | 64 Nm |
| Sensor | Torque | Torque |
| Gears | 8 | 7 |
| Brakes | Hydraulic disc, 180 mm | Hydraulic disc (Gemma GA-1000B), 180 mm |
The RadExpand 5 Plus lists more torque, which matters on climbs. Both are hub motors with a throttle. For steep terrain see best e-bikes for hills.
Battery & range
The XP4 lists a 500 Wh removable battery and claims up to 50 miles. The RadExpand 5 Plus lists 720 Wh, removable, and claims up to 60 miles. These are the makers' claimed maximums. Real range depends on rider weight, hills, assist level and temperature; try our range estimator. The XP4's top assisted speed is listed at 28 mph; our records do not list one for the RadExpand 5 Plus.
Fit, weight & storage
The XP4 weighs 69 lb with the battery (62 lb without it). It folds to 37 x 17 x 29 in, about 10.6 cubic feet by our arithmetic. It lists riders 4'10" to 6'3" and a 330 lb payload.
The RadExpand 5 Plus weighs 72.5 lb with the battery and folds to 29 in high, 25 in wide and 41 in long, about 17.2 cubic feet by the same arithmetic. It lists riders 4'10" to 5'10", a 315 lb payload and a maximum rider weight of 225 lb. Check that limit against your weight plus anything you carry. The step-thru frame can be easier to get on and off.
Tires: 20 x 3 in on the XP4, 20 x 4 in on the RadExpand 5 Plus.
Warranty, returns & service
Warranty. Lectric: one year on frame, motor, controller and battery for the first owner; wear parts such as tires, chain and brake pads are excluded. Rad (products bought after 15 May 2026): frame and listed components 2 years; battery 2 years or 300 recharge cycles; pedals, drivetrain and saddle 1 year.
Returns. Lectric: ineligible after 14 days in your possession; unused, original packaging, written approval; restocking fee up to $300 at its discretion; buyer pays shipping. Rad: 30 days from receipt for new bikes in original packaging (under 20 miles if used); return shipping at cost plus a 30% restocking fee are deducted from the refund.
Service. Lectric is sold direct, with certified partner bike shops handling service; owners contact Lectric support first. Rad lists Rad Mobile Service and velofix mobile mechanics (zip code dependent), retail stores and shop partners.
Rad ownership. Rad Power Bikes, Inc. filed for Chapter 11 bankruptcy on 15 Dec 2025 and sold substantially all assets. The brand has been under new ownership (Rad Life Mobility, part of Life EV) since 27 Feb 2026. Rad's warranty page says the current owner has no obligation to provide warranty or other service for products bought before 15 Dec 2025, and that claims on those bikes go through the bankruptcy process. The warranty above applies to products bought after 15 May 2026. Source: Rad's warranty page, checked Oct 23, 2026.
CPSC battery warning for older Rad batteries (24 Nov 2025). The U.S. Consumer Product Safety Commission told owners to immediately stop using Rad Power Bikes batteries with model numbers RP-1304, RAD-S1304Y and HL-RP-S1304 because of a fire risk, to remove them from the bike and to dispose of them through local hazardous-waste rules (not sell or give them away). The CPSC says they were sold with the RadWagon 4, RadCity HS 4, RadRover High Step 5, RadCity Step Thru 3, RadRover Step Thru 1, RadRunner 1, RadRunner 2, RadRunner Plus and RadExpand 5, and as replacement batteries; the model number is on the battery's label. Rad did not agree to a recall. The RadExpand 5 Plus is not named in the notice, but check your battery label. Source: CPSC warning.
Safety. Both are listed as UL 2849 certified in our records. Use only the maker's charger and follow the manual; see the CPSC Micromobility Information Center.
Which should you buy?
We recommend the Lectric XP4: price, weight, folded size and its higher weight limit all favor it, and it is listed as UL 2849 certified in our records.
We don't currently recommend the RadExpand 5 Plus or other Rad Power Bikes models. The CPSC has warned owners to stop using older Rad batteries (see the box above) and the company went through Chapter 11; see what Rad owners can do now. Its specs stay in the table for owners comparing the two.
Check the law checker for your state's rules before buying; it is general information, not legal advice. See all checked e-bikes.
