An apartment bike fails in the stairwell or the closet before it fails on the road. The useful numbers are what it weighs in your hands, what kind of fold the page actually describes, and how big that fold is. A 75 pound bike that folds still has to be lifted. A 38 pound bike with a folding stem may not get smaller than its wheels.
This is the best folding e-bikes shortlist for apartments and commuters, checked against Fiido, Engwe, and Tenways on October 12, 2026. The table is five current US listings: the Fiido D3 Pro, the Fiido M1 Pro, the Engwe EP-2 3.0, the Engwe L20 3.0, and the Tenways CGO600 Pro. The last one does not fold. It is here because 37 pounds can beat a fold if you have a corner and a bad staircase. We have not ridden them.
If the question is sand or a 4 inch tire rather than the closet, read the best fat tire e-bikes. Payload bikes that do not fold are in the heavy-rider guide. The folding and apartments page is the hub for this one.
What an apartment actually needs
Stair weight. This is the bike, the battery, and the lock, on the day you carry it. Fiido prints 38.1 pounds for the D3 Pro and 59 pounds for the M1 Pro. Engwe prints 75.4 pounds for the EP-2 3.0 and 76.1 pounds for the L20 3.0. Tenways prints 37 pounds for the CGO600 Pro. The Fiido Air, which does not fold, prints 30.3 pounds. We did not add a lock to any of those figures.
What folds. A folding stem is not a folding frame. The D3 Pro page says the stem folds. The M1 Pro, EP-2 3.0, and L20 3.0 pages say the frame folds. The CGO600 Pro page does not mention a fold.
Folded size. Engwe publishes one. The EP-2 3.0 is 97 by 53 by 81 cm. The L20 3.0 is 100 by 51 by 75 cm. Engwe also says the measurement can be off by up to 5 cm. Fiido's M1 Pro geometry is in millimeters: folding length 960, folding height 910, total length 1,778. Folded width is not in that list. A 96 cm fold is a closet shelf, not a briefcase.
The ride after you unfold it. Range, tire, and whether you can stand over the frame still matter. A folder that only claims 20.5 miles is a different commuter than one that claims 60.
Fiido D3 Pro
The Fiido D3 Pro (opens in a new tab) standard build was $549 on October 12, 2026, from $659. The Urban Edition on the same page was $599. Net weight is 38.1 pounds. The motor line is a 250W integrated-wheel hub. The feature list adds 35 Nm. The battery is 280.8Wh. Claimed range is up to 20.5 miles. Payload is 264 pounds on the spec list. Tires are 14 by 2.125 inch. Gearing is a single 52 tooth ring and a 12 tooth cog. Brakes are mechanical discs. Rider height is 4 feet 11 inches to 6 feet 1 inch.
The feature list says "foldable stem," not a folding frame. Folded dimensions are not published. The spec list also says the throttle's max speed is 6 km/h. That reads as a walk-assist limit. A class number is not in the spec block.
This is the light carry in the table. It is a poor match for a long commute or a soft path.
Fiido M1 Pro
The Fiido M1 Pro (opens in a new tab) standard build was $1,209, from $1,649. The Cargo Edition was $1,339. The frame folds. Geometry, in millimeters, lists a folding length of 960 and a folding height of 910. Listed weight is 59 pounds. The FAQ says 59.08 pounds with the battery and 52.31 without. Tires are CST 20 by 4.0. Payload is 264 pounds. Battery is 556.8Wh. Claimed range is up to 55.17 miles. The fork has 80 mm of travel. Brakes are dual-piston hydraulic discs. Gearing is Shimano 7-speed, 14–28, with a 52 tooth ring. Rider height is 5 feet 1 inch to 6 feet 7 inches.
Watts are blank on purpose. The feature list says a 250W, 50 Nm motor. The same page files the bike in Fiido's 500W collection and its Class 3 collection. We did not average those lines. Torque stays at 50 Nm because nothing on the page contradicts it. Class stays blank.
Fifty-nine pounds is a real lift, and a 960 mm fold is still long. It is the lightest full fold in this guide, and it is also a fat-tire bike. The fat-tire guide uses the same row.
Engwe EP-2 3.0
The Engwe EP-2 3.0 (opens in a new tab) was $1,499, from $1,899, and the page marked it in stock. The frame folds. Folded size is 97 by 53 by 81 cm. Bike weight is 75.4 pounds. A gross weight of about 88.8 pounds on the size panel is the package, not the bike. The motor is a 750W hub, 1,500W peak, 90 Nm. The battery is 48V 15Ah, 720Wh. Claimed range is 65 miles in PAS 1. Max speed is 28 mph. Tires are 20 by 4.0. Payload is 330 pounds. Rider height is 5 feet 5 inches to 6 feet 2 inches. Brakes are Tektro hydraulic, 180 mm. Gearing is Shimano Tourney 7-speed, 48 tooth ring, 14–28. The frame is a folding step-through. The assist line says the sensor can be set to torque or cadence.
A class number is not on the spec list. Certification is printed as UL, without a standard number in the lines we copied. The fold is for storage. It is not a stair bike.
Engwe L20 3.0
The Engwe L20 3.0 (opens in a new tab) was $1,599, from $1,999, and the page marked it in stock. It folds to 100 by 51 by 75 cm. Weight is 76.1 pounds. The motor matches the EP-2 3.0 on paper: 750W, 1,500W peak, 90 Nm, 720Wh. Claimed range is 60 miles in PAS 1. Max speed is 28 mph. Payload is 330 pounds. Rider height is 5 feet 0 inches to 6 feet 2 inches. Tires are 20 by 3.0 inch urban tires, so this is not the fat-tire pick. Gearing is Shimano Tourney 8-speed, 52 tooth ring, 14–28. Brakes are Tektro hydraulic, 180 mm. Engwe prints UL 2849, certified by TÜV Rheinland. Rear suspension travel is 30 mm. Standover on the size panel is 38 cm, which is the step-through.
The older L20 page is a different bike. It is below, and it was out of stock.
Tenways CGO600 Pro
The Tenways CGO600 Pro (opens in a new tab) chain builds were $1,599 on the US store, against a $1,899 compare-at price. Belt builds on the same page were $1,899. Some sizes showed sold out, so check stock. The headline says 37 pounds and up to 53 miles. It is a rear hub with a magnetic torque sensor and a portable battery. Drivetrain is a Shimano 8-speed chain or a Gates carbon belt single-speed. Size M is labeled for 5 feet 5 inches to 5 feet 11 inches. L and XL are offered, and those height bands were not in the block we copied.
Watts, torque, watt-hours, tire size, payload, and class are not on that page. The table leaves them blank. The page does not describe a fold. A CGO009 was not on the US catalog that day, so it is not in this guide.
The Tenways AGO X (opens in a new tab) is the other US all-rounder: an 80 Nm mid-drive, 504Wh, up to 62 miles, listed at $1,999 from $2,499, and sold out. It does not fold, and the US page does not print a tire size. It is in the fat-tire guide only so that blank is visible. It is not an apartment folder.
Fiido Air, if the stairs matter more than the fold
The Fiido Air (opens in a new tab) was $1,979, from $3,079. Net weight is 30.3 pounds. The motor is a 250W Mivice M070, and the feature list calls 35 Nm a peak torque. The battery is 208.8Wh. Payload is 264 pounds. Tires are 700 by 40C. The drivetrain is a Gates CDN belt. It does not fold. Claimed range is not a single published figure, so we did not print one. It is the lightest Fiido weight we found on the US store. It is the wrong bike if the closet needs a fold, and the battery is small for a long commute.
Fiido's US catalog that day did not list a complete D11 or a complete X. Those names still appear on parts. We are not linking a bike the store no longer sells whole.
Earlier Engwe pages that were out of stock
These listings were still on the US Engwe store on October 12, 2026, and each one showed out of stock. The current shortlist above is the in-stock fold. Check current price before you treat any of these numbers as a cart total.
The EP-2 Pro (opens in a new tab) was $1,399. The page says 960W peak, a 48V 13Ah battery, 20 by 4.0 inch tires, a Shimano 7-speed, Tektro mechanical discs, a 26 mph top speed, and a 75 mile maximum range. Nominal watts, torque, watt-hours, and bike weight are not printed.
The Engine Pro 2.0 (opens in a new tab) was $1,699. The page says 1,200W and 75 Nm, a 52V 16Ah battery, up to 68 miles in pedal assist, a folding frame, full suspension, a torque sensor, hydraulic discs, and 20 by 4.0 inch tires. It does not print a separate nominal watt rating or a bike weight.
The older Engine Pro (opens in a new tab) was $1,599. The page says both a 1,000W motor and 1,000W peak, a 48V 16Ah battery, a folding frame, 20 by 4.0 inch tires, full suspension, hydraulic discs, and an 8-speed Shimano. Torque and range are not in that description.
The L20 (opens in a new tab) was $1,399. It is a step-through with a 48V 750W motor, a removable 13Ah battery, front suspension, and 20 by 4.0 inch tires. The page does not say it folds. The L20 3.0 is the folding one.
The X26 (opens in a new tab) is a 26 inch fat-tire folder and was $2,199. It is written up in the fat-tire guide, because the tire is the point of that page. It was out of stock.
Names we are not linking out
Lectric's XP line, Brompton Electric, and Aventon's Sinch are folding bikes people compare against this list. We are not approved to affiliate those brands, so this page does not link to them. The Ride1Up and Aventon bikes already in our library do not fold. The under $2,000 comparison says so, and the Aventure 3 there is 76 pounds.

How to read the blanks
- Fiido D3 Pro. Standard was $549 on October 12, 2026, against a $659 compare-at price. The Urban Edition on the same page was $599.
- Fiido D3 Pro. The feature list says the stem folds. It does not say the frame folds, and folded dimensions are not published.
- Fiido D3 Pro. Torque of 35 Nm is on the feature list. The spec block says a 250W integrated-wheel motor and does not repeat the torque figure.
- Fiido D3 Pro. Payload is 264 lb on the spec list and 264.6 lb on the feature list. The table uses 264.
- Fiido D3 Pro. The spec list says the throttle's max speed is 6 km/h. That reads as a walk-assist limit. A Class 1, 2, or 3 label is not in the spec block.
- Fiido M1 Pro. Standard was $1,209 on October 12, 2026, from $1,649. The Cargo Edition on the same page was $1,339.
- Fiido M1 Pro. The feature list says 250W and 50 Nm. The same product page files the bike in Fiido's 500W and Class 3 collections. Those two watt figures disagree, so nominal watts and class are blank. Torque is only on the feature list.
- Fiido M1 Pro. Geometry is in millimeters: folding length 960, folding height 910, total length 1,778. Folded width is not in that list.
- Fiido M1 Pro. The spec list says 59 lb. The FAQ says 59.08 lb with the battery and 52.31 lb without.
- Fiido M1 Pro. Payload is 264 lb on the spec list and 264.55 lb on the feature list. The table uses 264.
- Fiido M1 Pro. The throttle line says max speed 6 km/h. That reads as a walk-assist limit, not a top speed.
- Engwe EP-2 3.0. Listed at $1,499 on October 12, 2026, from $1,899, and marked in stock.
- Engwe EP-2 3.0. Folded size is published as 97 × 53 × 81 cm. Engwe says measured and actual size can differ by up to 5 cm. Bike weight is 75.4 lb. A separate gross weight of about 88.8 lb is the package, not the bike.
- Engwe EP-2 3.0. Battery is 48V 15Ah, 720Wh. Max speed is 28 mph. A class number is not on the spec list.
- Engwe EP-2 3.0. The assist line says a torque sensor that can be set to torque or cadence.
- Engwe EP-2 3.0. Certification is printed as UL, without a standard number on the lines we copied.
- Engwe L20 3.0. Listed at $1,599 on October 12, 2026, from $1,999, and marked in stock.
- Engwe L20 3.0. Tires are 20 × 3.0 inch urban hybrid tires, not 4 inch fat tires. This row is a folder, not a fat-tire pick.
- Engwe L20 3.0. Folded size is 100 × 51 × 75 cm, with the same up-to-5 cm measurement note. Bike weight is 76.1 lb.

- Tenways CGO600 Pro. The page headline says 37 lb. It does not publish watts, torque, watt-hours, tire size, payload, or a class. Those cells are blank.
- Tenways CGO600 Pro. Size M is labeled for riders 5 feet 5 inches to 5 feet 11 inches. L and XL ranges were not printed in the block we copied, so rider height is blank.
- Tenways CGO600 Pro. The page does not describe a fold. A CGO009 was not on the US Tenways catalog that day.
A dash means the figure was not published, or two official lines disagreed. The Tenways row is mostly dashes because the US page did not print those specs. That is the page, not a guess we skipped.
How to choose without a test ride
Write down the staircase and the closet before the motor. If you will carry the bike, start at 38.1 or 37 pounds and accept what those two bikes are: a mini with a stem fold and a short range, or a light bike that does not fold. If you can roll it into an elevator, the EP-2 3.0 and the L20 3.0 publish the fold, and they weigh about 75 pounds. The M1 Pro sits between them: a frame fold, 59 pounds, and a watt figure we would not stake a purchase on until Fiido's 250W line and 500W collection say the same thing.
Then match the tire to the road. City pavement does not need 4 inch tires. A soft path does. That is the fat-tire guide. A 20.5 mile claim on the D3 Pro is a short loop. Do not plan a 15 mile commute on it and hope the footnote is generous. We have not measured any of these ranges.
Prices were on the brand pages on October 12, 2026. Several older Engwe pages and some Tenways sizes were already unavailable. Check current price at the button before you buy.
Accessories
A folder still needs a helmet, a lock that is not a long chain, lights, and a way to keep the bike covered if it lives on a balcony. The rack bag below fits a Topeak MTX rack only.

What we are not saying
These are the current US listings that answer an apartment question, not every folding bike on the market. A fold does not make a 75 pound bike easy to carry. A 37 pound bike that does not fold can still be the right one. We are not ranking by commission. Fiido, Engwe, and Tenways are the approved programs on this page. The order is stair weight, then a real frame fold, then a published fold size.
