Folding E-Bikes, Compared by Spec Sheet

Price check — October 23, 2026: Prices for Literider 2.0, XP4 (500W), Fold 1 were rechecked on the manufacturers’ US pages. Other prices and specifications remain the September baseline unless an October check is explicitly stated. Price bands below group the listed figures; they are not a fresh count of everything currently on sale. Confirm the selected version and current price before ordering.

A folding e-bike has to do two jobs well: ride like a useful everyday e-bike and fit the space where you plan to store or transport it — a trunk, a closet, a boat locker, a walk-up apartment, an RV bay. Start with folded dimensions when the manufacturer publishes them, then compare total weight, wheel and tire size, battery capacity, class configuration and the features you will use most often. This page compares the folding models in our six-brand September dataset, with the limited October checks noted above, with the numbers as their own product pages state them. We have not ridden any of them and we publish no ratings.

Folding models in this comparison

Sorted by price. DYU does not publish a Wh figure, so its battery is shown as volts × amp-hours; the C9 is listed and priced on the US store but does not appear in a DYU collection page, so confirm current availability before ordering.

Weight basis: published bike weights are not always measured on the same basis. Lectric states its weights without the battery and lists the battery separately; Rad publishes both figures; other manufacturers publish a complete-bike figure, and Velotric notes that its figure excludes fenders, kickstand and pedals. We preserve each maker's wording and flag the basis where it is known, so treat cross-brand weight differences as approximate.

Two common folding-bike design approaches

Read the wheel-size column and the list splits into two design directions.

Compact folders — 14-inch, 36 V, 42–51 lb, $259–$299 (DYU). These prioritize a smaller footprint and easier handling: 7.8 Ah packs, 25–45 claimed miles, 16–20 mph, and a published weight low enough that frequent lifting is realistic. Small wheels suit smooth pavement best.

Full-size folders — 20-inch, 48 V, 41–79 lb, $799–$1,899 (everyone else). These prioritize stability, battery capacity and utility while still folding for storage or vehicle transport, with 375–960 Wh packs and 45–85 claimed miles. Kingbull's Literider 2.0 and Verve add 4.0-inch fat tires and 720–960 Wh batteries, which makes them the folding options with the most range and all-terrain capability on this list; the fold is most valuable for storage, a car or an RV bay. Both sit alongside Kingbull's non-folding models on our Kingbull model page.

Neither approach is automatically better. If your constraint is lifting, start with the lighter compact folders and the XP Lite2. If your constraint is trunk or closet space, every bike on the list folds, and the choice comes down to battery, tires and class configuration.

What extra money buys, in order

$799 → $999. The XP Lite2 has a 375 Wh battery, a 300 W motor and a cadence sensor. The rechecked XP4 (500W) at $999 and Kingbull's Literider 2.0 at $979 offer a 500–720 Wh pack and either a torque sensor or a 750 W motor. Fold 1 is now $1,299 and belongs in the next comparison band. The Literider 2.0 pairs the largest battery in the band (720 Wh) with a 750 W motor and fat tires; the XP4 pairs a torque sensor with Class 3 capability.

$999 → $1,299–$1,449. The XP4 750 raises the battery from 500 to 840 Wh and the claimed range from 50 to 85 miles for $300. The Fold 1 price checked in October is $1,299. The Fold 1 Plus baseline lists a torque sensor, a 1100 W peak motor, the same 608 Wh battery and 68 claimed miles at $1,449; its current price was not rechecked, so do not treat the old $450 premium as current. Kingbull's Verve at $1,349 has the largest pack in the group at 960 Wh, a torque sensor and a 1400 W peak motor — the long-range folding option on this list.

Above $1,500. Rad's RadExpand 5 Plus is $1,899 for a 720 Wh, 750 W, Class 2 bike. Rad publishes a 20–60 mile range rather than a single best-case figure, which is a different way of quoting the same uncertainty.

Three specs that get overlooked on folders

Tire width is a design choice. Fat-tire folders (Kingbull's 4.0-inch Literider 2.0 and Verve, 71 and 77 lb) emphasize traction, stability, payload and battery capacity; the 3.0-inch folders from Velotric and Lectric (62–63 lb as published; Lectric's figure excludes the battery) prioritize a lower published weight and a smaller profile. Decide which matters more for where you ride and where you store the bike.

Wattage is quoted two ways. Nominal is the continuous rating and peak is the short burst. Lectric's XP4 is "500 W" nominal and 1092 W peak; Kingbull's Verve is 750 W nominal and 1400 W peak. Compare nominal to nominal.

A trike folds into a different shape. The Lectric XP Trike2 folds, but at 79 lb and with three wheels the folded package is a different shape from a two-wheel folder. It is on this list because Lectric lists it as folding.

Published folded dimensions

Folded dimensions are available for several of the most-shopped folding models, although manufacturers do not publish them in a uniform format or on the same page — Kingbull lists them on a separate size-and-fit page; Lectric, Velotric and Rad on the product page. Where a current figure is available, the maker's published L × W × H is shown below.

For the DYU models a folded figure was not found on the US product page when checked. If your bike must fit a specific trunk, closet, RV compartment or storage area, measure the space and confirm the current dimensions on the product page before ordering; it is one of the most useful numbers to confirm when storage space is fixed.

Rules and buildings

Class 3 configurations (28 mph pedal assist) are treated differently from Class 1 and 2 in many states, and some cities and transit systems have their own rules for e-bikes on trains, buses and in buildings. New York City requires e-bikes and batteries sold there to be UL certified, and many apartment buildings now ask for UL 2849 or UL 2271 before a bike or a charger comes indoors — a folding bike is more likely than most to be stored in a hallway or an apartment, so this applies more often here. Check the rules where you live and where you will store it, and see the class and UL guide for what each standard covers.
