Best Folding Fat Tire E-Bikes (2026): 8 I Rode, and What to Buy Instead

I’ve ridden eight folding e-bikes with 20 x 4 in fat tires on camera. As of Oct 26, 2026, most of the exact models I filmed are sold out or replaced at their brands’ own US stores. So this page starts with the newer versions you can buy today and what changed, from the brands’ spec pages. Then come my eight reference rides.

My best folding e-bike guide covers skinny-tire folders too. This page sticks to 4 in tires.

What you can buy today

Kingbull Literider 2.0

Literider video · Review of the one I rode

I haven’t ridden it. Here is what changed from the Literider I rode, by Kingbull’s pages.

It keeps the step-through frame and lists a 7-speed drivetrain, IPX6 water rating, a removable 48V 720Wh battery, 400 lb payload and a 5’2” to 6’6” rider range. Kingbull lists the rear rack at 150 lb.

Engwe EP-2 3.0

EP-2 Pro video · Review of the one I rode

I haven’t ridden it. This is the biggest change of the three.

Engwe also lists 750W (1,500W peak), 90 Nm, a 48V 720Wh battery that’s removable, UL 2849, a 7-speed Shimano Tourney, a GPS and 4G tracking module, IPX4, a 330 lb limit and a 5’5” to 6’2” rider range.

Rattan LF Ultra

Rattan video · Review of the one I rode

I haven’t ridden it.

Rattan also lists a 1,000W geared hub (1,800W peak), a 40.5Ah battery, up to 120 miles, full suspension with a suspension seatpost, a Shimano 7-speed, a 400 lb limit, a 5’3” to 6’4” rider range, 8 to 9 hours to charge, and UL 2849. The 32 mph figure is above Class 3. See the law section.

The eight reference rides

These are the bikes I actually rode. “Measured” means a number I recorded on camera. Everything else is what I saw or said in the video.

Amazon links below are my affiliate links. I couldn’t check Amazon stock, so each one says “check stock.”

Engwe EP-2 Pro

EP-2 Pro video · Review

I rode it for about two weeks (0:12 to 0:17). It arrived fully assembled with a small tool kit (6:17 to 6:30) and came with lights, a rear rack and fenders (1:22 to 1:34). A metal bracket keeps the folded bike off its chain (6:49 to 6:59).

Fold. Undo the handlebar latch, open the main latch, which has a second safety lock, flip the pedals down and fold it in half (4:25 to 4:42). Unfolding took about 30 seconds (7:33 to 7:43). It fit in my Model 3’s trunk (2:11 to 2:14), and with the seats folded I said two could fit (5:15 to 5:22).

Measured. 23 miles from full to empty, full throttle, no pedaling, on a hilly route at about 200 lb (7:49 to 8:22).

Weak spots. The fork is fine but not high quality (1:50 to 1:56), and starting on an incline felt a little slow (2:48 to 2:52). I said it was still pretty heavy, and the fat tires don’t help (5:24 to 5:30).

Brakes: 160mm mechanical discs (Engwe). Buy: Amazon (check stock)

Romatlink Dolphin

Dolphin video · Review

The Dolphin became our daily school run bike for the kids (5:55 to 6:01). It has two rear shocks under the passenger seat (4:03 to 4:10), plus a front fork and a suspension seat (4:13 to 4:24). The Engine Pro and Gyroor also have rear shocks; the Dolphin’s come with a passenger cushion and backrest.

Battery. After 25 miles the display still read 100% (2:50 to 3:05). That’s a gauge reading, not a range test. Romatlink lists a 48V 30Ah Samsung battery and up to 100 miles, or 80 miles on throttle only (7:12 to 7:29). Charging takes 9 to 10 hours (7:37 to 7:40).

Passenger kit. There are no foot pegs or grab handle, so I added both from Amazon for about $20 (3:09 to 3:42, 5:20 to 5:42).

Setup. It needs almost no assembly: install the pedals, unfold it and ride (9:32 to 9:40).

Trade-offs. It weighs 93 lb, one of the heaviest bikes I’ve tested (8:15 to 8:21). The throttle is limited by the pedal assist level (1:40 to 1:50), and the key stays in the battery while you ride (8:31 to 8:43). It has a cadence sensor (7:42 to 7:46).

Brakes: mechanical discs that take a hard squeeze at speed (2:12 to 2:16).

Price. On Oct 26, 2026, Romatlink’s page showed $599, listed down from $1,699. Its variants showed sold out while the page also said “In Stock,” so check stock. Romatlink lists 38.2 x 17.7 x 29.1 in folded, a 350 lb limit and a 132 lb rear rack. Buy: Romatlink (affiliate link, check stock)

Rattan LF 750 Pro

Rattan video · Review

Measured. 27 miles on a charge, solo, throttle only (7:34 to 7:49). Rattan quotes 30 to 45 miles, which I said is usually measured with pedal assist (7:49 to 8:01).

Ride. At 6’1”, the riding position was exactly what I wanted (6:55 to 7:02). The suspension seat post worked well over bumps (2:40 to 2:50), and the tires handled a snowy trail beautifully (7:09 to 7:20). Power dropped noticeably when the battery got low (3:07 to 3:17).

Passenger. The rear seat has a backrest. Kids said it was really comfortable (2:50 to 3:07). For me as an adult passenger it was snug and felt imbalanced (3:20 to 3:55). The rider’s pedal came within about 3.5 to 4 in of the passenger footrest (2:03 to 2:24).

Controls. The throttle only works in a pedal assist mode (1:08 to 1:16), and the key stays in while you ride (1:40 to 1:53).

Brakes: piston brakes (8:29 to 8:31). Buy: Amazon (check stock)

Rattan also lists an LF Pro 2.0, but only as a Europe-only pre-sale, not confirmed for the US.

Kingbull Literider

Literider video · Review

Folded, the low step-through frame works as a carry handle (0:24 to 0:41). I sat on the rear rack at about 200 lb and it held, though I said I didn’t know if it was rated for that (3:35 to 3:47). Warning: don’t copy that. Kingbull rates the Literider 2.0’s rack at 150 lb, and I couldn’t find a rack rating for the one I rode.

Measured. About 30.9 mph on PAS 5 (2:02 to 2:12). I said I didn’t think that speed was set up correctly for US rules (0:47 to 0:54).

What I’d change. Cheap-feeling grips (1:46 to 1:52), a display that’s hard to see in sun (2:22 to 2:25), and folding pedals that flipped out when not fully locked (3:10 to 3:25). The handlebar height adjusts (4:18 to 4:31). Front fork, no rear suspension (3:47 to 3:51).

Brakes: hydraulic discs (2:37 to 2:41). Buy: sold out; see the Literider 2.0 above.

Engwe Engine Pro

Engine Pro video · Review

I tested it with Engwe’s optional rear-rack battery, about a $400 add-on (0:18 to 0:32). It has a front fork and a rear shock and was very comfortable on rough ground (4:31 to 4:41). Hold the throttle steady for about 5 to 7 seconds and cruise control takes over (2:51 to 3:08). It has folding pedals (4:41 to 4:48) and a cadence sensor (4:48 to 4:58).

What I didn’t like. Lots of external cabling (5:14 to 5:39), the key stays in while riding (5:42 to 5:58), a rattling rear fender (4:12 to 4:21), and no display reading for the second battery (6:45 to 6:59). Engwe says that battery doubles the range (7:01 to 7:08). Engwe lists 69.88 lb and 330 lb.

Brakes: hydraulic discs (0:59 to 1:00). Buy: sold out at Engwe on Oct 26, 2026 (the Engine Pro 2.0, at $1,699, was also sold out). Amazon (check stock)

Luckeep X1 Pro

Luckeep video · Review

It carries one battery in the frame and one behind the seat, which is where Luckeep’s 120-mile claim comes from (0:37 to 0:49). The 750W rear hub had plenty of power on steep inclines (4:19 to 4:27). Comfort comes from the tires, a suspension seat post and a front fork (4:31 to 4:41). I said you could carry the rear battery into the office and charge it at work (4:48 to 5:03).

Fit and frame. The seat post adjusts for shorter or taller riders, and the stem is telescopic (2:28 to 2:41). Luckeep’s size page, which I checked on Oct 22, 2026, lists 81 lb, a 440 lb limit and 28 mph. The display is simple and a little hard to see (3:18 to 3:25).

Brakes: hydraulic discs front and rear (3:12 to 3:16, 3:54 to 3:59). Status: on Oct 26, 2026, luckeepbike.com had no X1 Pro product page. Buy: Amazon (check stock)

Tesgo STT and Gyroor C5 Max

Gyroor vs Tesgo video · Tesgo review · Gyroor review

I rode them back to back (0:15 to 0:21). The Tesgo’s 1,000W motor is twice the Gyroor’s 500W, and you feel it (7:36 to 7:47). I got the Tesgo well over 20 mph (8:01 to 8:06), and it’s much quicker off the line (9:19 to 9:27). Its Y-shaped frame kept hitting my heels, which I called a poor design flaw (5:13 to 5:50).

The Gyroor has front and rear suspension (2:16 to 2:23), a cadence sensor (2:46 to 2:55), and rode really smoothly (3:29 to 3:35). Its charge plug kept falling out (2:26 to 2:44). The Tesgo adds a suspension seat post (3:45 to 4:03), a beefier rack and a brake light (6:14 to 6:32). Gyroor’s blog lists the C5 Max at 63 lb.

Brakes: Tesgo, dual hydraulic (Amazon listing, checked Oct 24, 2026). Gyroor, not listed. Neither brand had a current product page on Oct 26, 2026, so I’m not linking either.

Folded size, trunks and apartments

Measure your trunk first. The EP-2 Pro fit my Model 3 (EP-2 Pro video, 2:11 to 2:14), but every bike on this page is 63 lb or more by the maker’s figure, so plan on lifting that to bumper height. For an apartment, a removable battery means you can carry the battery up and leave the bike in storage. Kingbull, Engwe and Rattan each list a removable battery on the three US bikes above. Charge it the way the manual says.

Fat tire care

All of these run 20 x 4 in tires with inner tubes. Kingbull lists CST puncture-proof tires and Schrader tubes on the Literider 2.0. Engwe lists a 3mm anti-puncture layer on the EP-2 3.0. Run the pressure printed on the sidewall and carry a spare tube.

Buying one used

• Check the CPSC recall list for the exact model.
• Ask about the warranty. Engwe’s warranty excludes second-hand bikes, so assume a used Engwe has none.
• Get both keys and the charger. The Dolphin, Rattan and Engine Pro all need the key in the battery while you ride.
• Test the fold. Every latch, including the EP-2’s safety lock, should close firmly. Make sure the folding pedals lock.
• Ask how much charge the battery holds. Engwe treats capacity under 60% as a battery fault.
• Squeeze the brakes. Mechanical discs on the Dolphin and EP-2 Pro need regular adjustment.

Carrying a passenger

The Dolphin and Rattan are built for a second rider. Romatlink lists a 350 lb limit (Dolphin video, 6:55 to 7:00), and Rattan’s spec page lists 300 lb for the LF 750 Pro. Both limits count the rider, and two adults reach them fast.

Passenger laws vary by state. In California, a passenger has to sit on a separate seat, and a passenger 4 or younger, or 40 lb or less, needs a seat that holds them in and protects them from moving parts (Cal. Veh. Code 21204). On a Class 3 e-bike, California requires a helmet for the rider and any passenger, and riders must be 16 or older (Cal. Veh. Code 21213). Check your own state on /laws/.

Range on this page

My numbers are the EP-2 Pro’s 23 miles and the Rattan’s 27 miles, both on throttle. The Dolphin’s 25 miles was a gauge reading. Every other bike here, and all three newer models, is not range-tested by me, so their range figures are the maker’s.

Class and the law

Class 1 is pedal assist to 20 mph, Class 2 adds a throttle to 20 mph, and Class 3 is pedal assist to 28 mph. My e-bike classes guide explains them, and /laws/ has state rules.

• Kingbull Literider: I measured about 30.9 mph on pedal assist, over Class 3’s limit. The 2.0 is listed as adjustable up to 28 mph.
• Rattan LF 750 Pro: 28 mph on pedal assist in my video (Rattan video, 8:08 to 8:16). The LF Ultra is listed at 32 mph, above Class 3.
• Engwe EP-2 Pro and EP-2 3.0: 28 mph on pedal assist, measured on the Pro and listed on the 3.0.
• Luckeep X1 Pro: listed at 28 mph.
• Tesgo STT: its Amazon listing says 32 mph.

A bike faster than its class may not count as an e-bike where you live. Check your state before unlocking any speed setting.

Who shouldn’t buy a folding fat tire bike

• Anyone who can’t lift about 65 lb. The lightest listed weight here is 63 lb (Gyroor), and the Dolphin is 93 lb.
• Riders carrying a bike up stairs every day. Folding makes it smaller, not lighter.
• Pavement-only commuters. Fat tires add weight and drag you don’t need on smooth roads.
• Anyone who wants a torque sensor on a bike I rode. The Literider, Engine Pro, Dolphin and Gyroor use cadence sensors in my videos. The EP-2 3.0 is the only bike here with a listed torque sensor.

FAQ

Which folding fat tire e-bike should I buy today? Of the three in stock, the Literider 2.0 is the cheapest at $979 and keeps the step-through. The EP-2 3.0 adds a torque sensor and hydraulic brakes. The LF Ultra has the biggest battery. I haven’t ridden any of them.

Will one fit in a sedan? The EP-2 Pro fit my Model 3, and the Rattan and Literider fold to sedan size in my videos. Check the folded sizes above against your trunk.

Can they carry a passenger? The Dolphin and Rattan are built for it. Add pegs and a grab handle, stay under the limit, and check your state’s passenger rules.

Which of these are Class 3 speed? The EP-2 Pro, EP-2 3.0, LF 750 Pro, Luckeep X1 Pro and Literider 2.0 (when set to 28 mph) reach 28 mph on pedal assist by my test or their listings. The Literider I rode, the LF Ultra and the Tesgo go past 28 mph. Check /laws/.
