Should you buy one?
Buy the Tesgo STT only if speed matters more to you than anything else. For most people shopping for a folding fat tire e-bike, I’d buy the Gyroor C5 Max instead, and that’s what I said I’d pick for myself when I rode them back to back in November 2022.
Here’s the trade. The Tesgo’s 1000W rear hub motor is ridiculously fast. I got it well over 20 mph, and off the line it pulls way harder than the 500W Gyroor. It feels quicker than the bigger, heavier 1000W e-bikes I’d ridden before. But it’s a big bike: Tesgo lists it at 66.1 lb, and the frame flares out into a Y shape near the pedals where my heels kept hitting it. The Gyroor is slimmer, has rear suspension, and folds into a smaller package.
So the answer is simple. If you want the slimmer folding bike, buy the Gyroor. If you strictly want speed and can live with the heel problem, buy the Tesgo. Before you do, read the legal box below, because a 1000W motor and a 28 mph listed top speed take this bike outside the usual e-bike definitions.
Buying note: as of Oct 24, 2026, the only US prices I could find were two reseller listings: $1,499.99 at viewmobility.com and $1,800 at bikesw.com. I couldn’t confirm a price from Tesgo itself. My link below goes to Amazon, so check the current price there.
Legal box: this may not count as an e-bike where you live
- Motor. Federal law (15 U.S.C. 2085) defines a low-speed electric bicycle as having a motor of less than 750 watts that tops out under 20 mph on motor power alone. The Tesgo’s motor is 1000W, so it falls outside that definition.
- Speed. Tesgo lists a 28 mph top speed, and its Amazon listing says up to 32 mph. Class 2 bikes have a throttle but stop at 20 mph. Class 3 bikes assist to 28 mph but are defined as pedal assist only, with no throttle. A bike with a throttle that reaches 28 to 32 mph doesn’t fit either class. My e-bike classes guide explains how some states handle throttles on faster bikes.
- What that can mean. Depending on your state, a bike like this may be treated as a moped or motor vehicle. That can mean registration, a license or insurance, and it may be banned from bike paths and multi-use trails. I’m not a lawyer, and I didn’t research every state. Check your state in my e-bike laws by state page and with your DMV before you buy.
STT or STT 4.0?
Tesgo’s Canadian site, its Amazon listing and the resellers all call this bike the STT. The owner’s manual on manuals.plus calls it the STT 4.0. I don’t know whether those are two versions or two names for the same bike, and my video doesn’t show a model badge that settles it. Some of the spec gaps above (battery size, load rating, rider height) could come from version differences. I’m calling it the STT because that’s the name Tesgo uses on its site.
Pros and cons
Pros
- 1000W rear hub motor with a ton of power
- Way faster off the line than the 500W Gyroor
- Feels quicker than heavier 1000W bikes I’ve tested
- Throttle works from zero
- Color display with a nice readout of output
- Comfortable, premium hand grips

Cons
- Y-shaped frame flares out near the pedals; my heels kept hitting it
- Heavier and beefier than the Gyroor C5 Max (66.1 lb listed vs 63 lb)

The motor: why you’d buy it
The Tesgo has a 1000W motor, twice the power of the Gyroor’s 500W. You can really feel it. I’m about 200 pounds, and the Gyroor’s 500W is plenty for me, but the Tesgo’s 1000W is pure joy. Off the line, you get way more torque from that rear hub motor than you do on the Gyroor.
What surprised me most is how quick it feels. The other 1000W e-bikes I’d tested had big, heavy frames and larger fat tires, and they didn’t feel as quick. I said in the video that the Tesgo felt lighter than those. Don’t read that as a light bike: Tesgo lists it at 66.1 lb.
With this much motor, I said, why would you pedal? The throttle does most of the work, which takes some of the sting out of the heel problem below.
Controls and display
The controls look similar to the Gyroor’s. The Tesgo has the same comfortable, premium-feeling hand grips, which make it much nicer to rest your hand on during a long ride.
The Tesgo uses a thumb throttle instead of the Gyroor’s twist throttle. Turn the bike on and you get a color display, a nicer display than the Gyroor’s. It gives you a nice readout of your output.
On the left you have the front brake and the up and down buttons for pedal assist. Or you can just use the throttle, which works from zero.
On the right you have a hand grip, the rear brake and the shifter. I said the shifter works a little differently from the Gyroor’s, but it’s the same name brand most e-bikes use. Tesgo lists Shimano 8-speed gearing, and bikesw.com names the derailleur as a Shimano Altus.
Frame, folding and the heel problem
The neck folds, very similar to most folding e-bike designs. You get a front fork suspension, a headlight and fenders.
The Tesgo is definitely beefier in terms of frame thickness. The frame goes out into a Y, and that’s where my problem started. My heels kept hitting the part of the frame that bows out, and the close-up of my foot on the pedal shows how near the heel gets. My feet aren’t huge, and if you have smaller feet you probably won’t have an issue. For me, it was a poor design choice. They made it way too thick.
In the video I called this my only complaint. Overall, I said the build was great. The heel problem is the one thing I’d hold against the frame, and you notice it every ride. If you can, sit on one and pedal a few turns before you buy.
Seat, suspension and rack
The Tesgo seat is pretty decent. It has a shock under it, so you get some up and down travel in a more plush seat. Tesgo lists this as seat post suspension. It makes up for the rear suspension the Gyroor has and the Tesgo doesn’t. It cushions you, not the frame or the rear wheel.
Rack or basket? The Tesgo has a beefy rear rack, especially compared to the Gyroor’s. The bike I rode also had a basket on the back. I said in the video that I believe the basket was optional, and it might have been included at the time I recorded. Bikesw.com’s listing talks about adding panniers, platforms or baskets to the rack, which fits the basket being an add-on. Neither Tesgo nor the reseller lists a rack weight capacity.
One fitment note: the seat almost hits that back basket. If you need the seat a little lower, it’ll run into the basket. That’s a smaller issue than the heel problem, and if you skip the basket it may not apply.
I also really like the rear tail light. When you squeeze the brake, it lights up, which is a really nice touch. The Gyroor only has a reflector back there.
Tires and weight
The tires on the Tesgo and Gyroor are about the same meatiness, and I’d expect them to perform about the same. The Gyroor tire has a little more meat on it. Bikesw.com lists the Tesgo’s tires as CST 20 x 4.0 inch fat tires.
Both bikes are a little heavy. The Tesgo is definitely heavier than the Gyroor, and you can tell from how beefy the frame is compared to the Gyroor’s slender frame. Tesgo lists 66.1 lb, and the Gyroor C5 Max is listed at 63 lb.
What the specs mean on the road
1,000W on a fat tire folder. Twice the Gyroor’s 500W. I felt the gap most off the line.
48V 17.4Ah, about 835Wh. That’s a big battery for a folder, bigger than the Gyroor’s 576Wh and the Engwe EP-2 Pro’s 624Wh. Tesgo’s 40 to 70 mile range is its claim; I didn’t test range.
95 Nm. That’s Tesgo’s torque figure, and it fits how hard the bike pulled off the line for me.
66.1 lb. Heavy to lift into a trunk, even folded.
6 to 8 hour charge. Per bikesw.com, with a 2A charger. Plan on charging overnight.

Gyroor and Engwe figures come from my Gyroor C5 Max review and Engwe EP-2 Pro review. The EP-2 Pro has two speeds because Engwe lists 26 mph, while I saw 28 mph in its top pedal assist level on my test ride.
- Gyroor C5 Max: slimmer, with front and rear suspension, and the folding e-bike I’d personally buy of these two. Its 220 lb load limit is low, though.
- Engwe EP-2 Pro: another folding fat tire bike, now discontinued.
- Rattan LF 750 Pro: a folding fat tire bike with a rear passenger seat.
Who it’s for
- Riders who want speed from a folding fat tire bike, and who’ve checked their local rules.
- Heavier riders or riders who carry things. Tesgo lists 350 lb, and the rear rack is beefy.
- Riders with smaller feet, who probably won’t hit the frame.
Who should look elsewhere
- Riders with bigger feet or a wide pedaling stance; the Y frame got in my way.
- Anyone who wants the slimmest folding package. The Gyroor is slimmer.
- Riders who want rear suspension. The Tesgo only has a seat post shock.
- Anyone who needs a bike that’s legal on bike paths everywhere. See the legal box.
What the ride footage shows
There isn’t much riding in this video. Most of it is a walkaround of both bikes side by side on a driveway. The riding clips are short: a sunny day with a blue sky, on a dry paved road with dry grass on both sides, and it’s flat. That’s where I got the Tesgo well over 20 mph. The close-up of my foot on the pedal shows how near the heel gets to the flared frame. The tire sidewall in the footage reads 20 x 4.0.
What I measured on camera: well over 20 mph (video, 8:01).
What I didn’t test
- Range. I didn’t do a range test on the Tesgo.
- Hills. All the riding I filmed was on flat road.
- Braking distance. I showed the brake levers and the brake light, not a stopping test.
- A measured top speed. I said “well over 20,” with no GPS reading.
- Folding time. I showed the neck fold, not a full fold and carry.
- Weight. I didn’t put either bike on a scale.
- Charge time, battery removal and rack load. None of these are in my video.
Where the sources disagree
Checked Oct 24, 2026.
| Item | Tesgo Canada site | Amazon listing / manual | Resellers (bikesw, viewmobility) |
|---|---|---|---|
| Battery (Ah) | 17.4 | 17.5 (title); 15 in the listing text | 17.4 (840Wh) |
| Top speed (mph) | 28 | Up to 32 | 28 |
| Weight (lb) | 66.1 | not listed | 67.8 |
| Max load (lb) | 350 | not listed | 330 |
| Range (mi) | 40-70 | 40-50 throttle, 60-70 pedal assist | 40-60 |
| Rider height | 5’2” to 6’5” | not listed | 5’4” to 6’4” (bikesw) |
| Model name | STT | STT 4.0 (manual) | STT |
Both reseller pages list Samsung cells. My video doesn’t settle any of these. I can only say it’s heavier than the 63 lb Gyroor, which fits both the 66.1 and 67.8 lb figures.
Recall check
I searched the CPSC recall database for Tesgo on Oct 24, 2026 and found no recalls.
FAQ
How fast is the Tesgo?
I got it well over 20 mph but didn’t measure a top speed. Tesgo’s Canadian site lists 28 mph, and the Amazon listing says up to 32 mph.
Is the Tesgo STT street legal as an e-bike?
It depends on your state. Its 1000W motor is over the 750W federal definition, and a throttle bike that reaches 28 mph doesn’t fit Class 2 or Class 3. See the legal box above.
Tesgo or Gyroor C5 Max?
For a folding e-bike, I’d go with the slimmer Gyroor. If I strictly wanted speed, I’d go with the Tesgo, because it’s way faster, especially off the line.
Does the throttle work from a stop?
Yes. The Tesgo’s thumb throttle works from zero.
Does it have rear suspension?
No. It has a front fork and a shock in the seat post instead.
What’s wrong with the frame?
The frame flares out into a Y near the pedals, and my heels kept hitting it. Riders with smaller feet may not notice.
How much does the Tesgo STT weigh?
Tesgo’s Canadian site lists 66.1 lb, and two resellers list 67.8 lb, as of Oct 24, 2026. I didn’t weigh it.
What’s the weight limit?
Tesgo’s Canadian site lists 350 lb. Two resellers list 330 lb. Plan on the lower number.
How long does it take to charge?
Bikesw.com lists 6 to 8 hours with a 2A charger. Tesgo’s page doesn’t list a charge time, and I didn’t time one.
Has the Tesgo STT been recalled?
I found no CPSC recall for Tesgo as of Oct 24, 2026.
Price
I didn’t give a price in my video. As of Oct 24, 2026, viewmobility.com lists the Tesgo STT at $1,499.99 and bikesw.com at $1,800, and I couldn’t find a price on Tesgo’s own site. The Amazon listing from my video description no longer exists (checked Oct 26, 2026). For other options, see my best fat tire e-bikes guide and my list of the best e-bikes under $2,000.
