I recently purchased two of these E bikes. We are very happy with the quality and price of these bikes so far. They are absolutely a great value very comfortable. Holds a charge well and has great speed. We did have a little issue with shipping in which I needed to reach out to the customer service. They were very friendly, responsive, and accommodating overall, I’m very happy with my purchase and would definitely recommend these.

Here’s a smoother, more polished version of your review while keeping your voice: --- I bought this bike intending it to be my daughter’s starter bike, but it turned out to be so great that she wants to keep it forever. There’s an app you can use to control the speed, which is perfect for beginners or for switching to a faster Class 3 mode as she gets more comfortable. Assembly was pretty easy—my 12-year-old and I put it together in under an hour, and she was out riding right away. It comes with a headlight and cable brakes, and the seat is large enough for two people, which is a nice bonus. The battery life has been impressive. She takes long rides around the neighborhood with her friends, and it usually only drops one bar. I’ve ridden it a couple of times myself, and it’s great for both kids and adults. Overall, it’s an excellent bike for the price—I wouldn’t even consider spending more on a higher-end one.

Judt like the title this bike is fast! and a more affordable ebike compared to higher prices. This has a great milage, easy to assemble just make sure to align your front tire properly so it doesn't grind on the break. This gets me to places here and there especially within a 5 mile area it feels like a light breeze.

The bike looks great and feels very sturdy. We really liked the fat tires and the dirt bike style design. Assembly was straightforward and everything was well packaged. Unfortunately our son had an accident on the very first day and the suspension fork got badly bent, but TST customer service was extremely responsive and helpful with getting us a replacement part quickly. So far we’ve had a very positive experience with their support team and appreciate how fast they handled the issue.

Bike was nice for the time that I was able to ride it, however support is horrible. If you ever have an issue with the bike, you won’t be able to get the help that you need. I contacted support and I’ve been ghosted. I bought this bike last December, and as of April, it’s giving me E5 and E7 errors that have to deal with motor damage which I don’t understand because I’ve riden the bike normally everytime. I have about 400 miles on it and it not working after 4 months is not great. Also, after falling with the bike just once, the plastic caps on the left and right of the suspension forks came off, so the front fork is able to move freely which is dangerous. I’d save your money and not spend it with this company/brand. Also I wasn’t able to install the derailleur guard because the nut bolt came stripped. The speed is nice but you don’t get much range with it. Battery life could be better. Also as a 6’4 rider it feels uncomfortable to pedal and not having the seat adjustable was a killer. So if you’re tall, stay away from this bike despite it being for people 5feet to 6 feet four. As far as assembly, they had a video that showed how to assemble a bike similar to it but not the actual bike, so I had to do a lot of figuring out how to assemble it. Took like 4 hours. Overall bike is okay, customer support is horrible/hard to get reach of Also their accessories are very expensive. You could install a trunk box on the rear seat of the bike but it costs $170 which you can only get on their website.. not much adjustments you can do.

This ebike is a mix of good news and not-so-good news. Keeping in mind that the price was $720 (good news), expect a few areas of cost cutting and inattention (not so good). I'm in California, so maybe this is just for local sales but the bike has a sticker behind the "seat tube" that states "Class 2 ebike, limited to 20mph". Not exactly as advertised. I decided to register the bike as a "moped" to avoid issues with the crazy and constantly changing California ebike class system. It's a simple, one-time $28 registration with several benefits and a few requirements that I meet. A note to TST...how about a "MOPED" setting in the software. 30 mph, headlight automatically on with power up, persistent turn signals. Overall the classic (retro) moped step through frame, bench seat, integrated battery, mounting for a top box, 20x4 tires and full suspension are exactly what I was looking for. So, good news. So, now some observations.... Documentation Quality: Not so good. The user manual has QR codes printed on the front page. One is supposed to go to an assembly video, but goes to an unrelated 27" bike model instead. Use the video on the Amazon page instead, it's pretty good. The QR code to the Android app goes to "Orbital Sports" and definitely download this, connect it with Bluetooth, and look around in the device settings for ebike class (good news). BUT...the included printed "User Manual" is mostly about assembly and is completely useless for a User. This "User Manual" lists recommended service but has nothing about how to accomplish even the most rudimentary tasks (like changing a tire, more later). Keys: not so good...one of the two keys had broken plastic. Fixed it with super glue, but it shouldn't come this way out of the box. Paint: several areas were scuffed or scratched out of the box. Disappointing. BTW: Google translates the Chinese characters on the battery decal as "Battery Decal" :) Assembly: good news...fairly easy, good selection of tools included. Not great tools, but good enough and most of what's needed. Motor: advertised as 1500W, sometimes 750W. Advertised 32 mph, sometimes 28 mph, my reality is 26-27 cruising and occasional 28 with enough runway on level ground. Enough for my needs. Battery: advertised as 48V-15Ahr special for the 1500W motor, with 40 mile range in throttle mode. 1500W at 48V would require an ideal 31.25A from the battery...unlikely. In my experience the 40 mile throttle range is more like 20-25 with noticeable slowing at lower battery levels. Uphill sag is extensive, falling from 24-26 to 14-16 on a freeway overpass (not much of a hill). Gears/Shifter: good news...Shimano 7 speed, not their best but still quality. Brakes: good news...C-Star hydraulic discs, effective but the calipers need centering to keep them from rubbing. Also a little spongy after a couple months so a bleeding kit is a good idea. (nothing in the "User Manual" about either) Pedals: nothing good news here. replace. Controls: good news...effective but reposition everything. Brake levers, shifter and control panel are too high. Best if they are inline with your arm and natural to use. Turn Signals: nice feature but self-cancel after about ten seconds; not nearly long enough when stopped at a light or in a turn lane. Need a least 90 seconds, or a manual cancel. Brake light: also nice feature, not a traditional dim/bright but instead the tail light flashes. OK... Headlight: not so good...almost no illumination at night and barely visible during the day. Replaced it with a much brighter unit with daytime running light. Chain Guard: crank arm hits the chain guard, a little bending of the bracket solves this. Seat: not so good for me (6'1"-185lbs); front seat is short, narrow and collapses to the seat base under my weight. Same for back seat. Replaced the front seat with a custom seat that fits my posterior and doesn't bottom out. Replaced the back seat with an adapter for the top box. Seat Rail: good news...remove the rear seat and it's a perfect place to mount a top box. Gonna need an adapter and the three holes for the rear seat are really convenient. Rear Shocks: depends...they look like coil over damper, but the "damper" is just a slide with no damping. Adjustable pre-load is some good news; the web pictures don't show it but it's there and pretty good for this price point. They come with the preload all the way up (stiff); probably because they advertise the bike to carry a passenger. If you ride solo and aren't 450 lbs then the "shocks" are useless since even adjusting the pre-load to zero gives NO compliance from the springs. It's basically a hard tail for a solo rider (not so good). I replaced both rear "shocks" with a pair of air adjustable units from MEROCA (purchased on Amazon). Still dialing them in but so far it's a big improvement; makes the ride MUCH more comfortable and improves control. Tires: not so good, but maybe just for my application. Tires are very knobby, noisy, bumpy and THIN. Back tire flatted within the first month of riding on paved streets. Replaced both tires with Ultraverse Road Dominator tires (purchased on Amazon) and HUGE improvement. Also learned that removing the rear wheel requires disassembly of the battery connector in the downtube compartment to access the motor connectors to the controller, since there is no intermediate connector from the controller to the rear hub. (the bike was $720 so...short cuts) (also nothing in the "User Manual") Throttle: really not good news. Typical thumb throttle on the left side. It worked fine for the first couple months but recently has introduced an interesting quirk. With the bike stopped, power on but not touching the throttle, the bike will take off at full speed by itself. First time it just ran into a pile of fertilizer bags and I thought maybe I accidentally touched the throttle. Second time it almost shot me into a busy intersection and I know I didn't touch the throttle. Pulling either brake lever will stop it. Now it happens randomly so I keep my hand on the brake lever whenever the bike is stopped with the power on. This might need a replacement throttle, or maybe a complaint to the NTSB, haven't decided. In summary the not-so-good news is about even with the good news, and there is the throttle thing. If it's toy it might not matter, but think twice if you plan to use it for transportation or give it to a child. At this price it's a decent starting point if you want a project and have the skills and equipment, but NOT as a "buy it and ride every day safely" purchase. I'm keeping it, modifying it and using it just about every day for commuting and errands. Better for around town (5-15 miles round trip) than my van, especially with gas prices skyrocketing. BUT...stay tuned for more on the "death wish" throttle.
