Solid e-bike and very affordable. Customer service is very helpful and surprisingly easy to get ahold of. I purchased two TST e-bikes with no regrets. Highly recommend. Pros: Very affordable. 28mph speed. Solid frame. Small storage space under seat. Battery gives good range/distance. Excellent customer service from manufacturer. Cons: No foot pegs for back passenger. Tire tread wears down fast. No quick disconnect motor cable for rear wheel which is helpful when replacing inner tube, but still no issues getting it done. The pros outweigh the cons by far. Don’t waste your money on those other overpriced e-bikes.

My son bought this to get outside more and it took a bit to put it together, but after he got it together, it was sturdy strong practically all of the parts are made of metal and the only thing that he that he had an issue with was the back brake sticking, but besides that all around amazing bike light is not as bright as he thought it was but still amazing bike 4/5⭐️

Fantastic bike, came with a tightened break manufacturer tried to help with problem solve but when that didn't work they replaced the part. Break now works great. Not adjustable. Highly not recommend for someone under 5'5. way taller than I thought. Cat uses it we a cat tree when not in use.

Do not order from this seller. Product arrived with damage from the factory. The rear wheel had a machining gouge (see pics) that exposed the aluminum - I can expect a rust spot and excessive wear there. And it's a mechanical defect - a potential failure is lurking literally "down the road". That's the first start point of dissatisfaction. Repeated attempts and messages to seek a resolution were largely ignored. False advertising was the second issue. Product did not arrive with the equipment shown in the listing (foot pegs are shown). The phone holder is mechanically weak and prone to breakage. The chain is so flimsy that any motivated thief would be able to cut through with any bolt cutter handy. Wrt the foot pegs, Seller did not resolve that either and blamed it on their marketing staff. Third, like reported in another review (I should've listened to my gut), the front fender bolts were painted over during the powder coating process and we're exceptionally difficult to remove. If you aren't adept at removing screws after they have been powder coated over, you can forget getting them out constructively - another reviewer had to drill them out. Which means the reviewer had to go to the hardware store and obtain new screws just to mount the fender and be able to ride the bike. Lastly, Seller said they would resolve open issues in 24 hours then ghosted. I've spent well over $50K with Amazon. Interacted with a wide variety of products ranging from high tech to household goods. As a certified quality engineer, take my advice or expect disappointment - do not buy from this seller. They are dishonest and their quality is grossly diminished. You would expect that if a company/seller have quality issues, they would, at least, be diligent in responding to and applying corrective action to said quality issues. Nope. These folks just pump out poor quality and collect the consumers' money. Spend your money elsewhere. Products that cost this much have an expectation of superior mechanical quality - and this seller is not committed to the reciprocity between consumer and merchant. Again - buyer BEWARE.

Bike is cool. Runs well and will get you from A to Z. Battery life is really random though. Will loose first bar really fast. When it gets to 2 bars it will just jump 0 really fast as well. You can go 28mph. But not without losing battery really fast. The best way to use this bike is with low PAS. The seats are surprisingly comfortable. Headlight is really bright. Turn signals are useful l. Overall it’s worth the value but there are comparable models that are more affordable

I’ve had this electric bike for 3 weeks now and it’s exceeded my expectations! The 1500W motor is a beast—accelerates quickly and hits 30MPH smoothly, even when I’m riding on bumpy off-road trails. The dual suspension makes the ride super comfortable, no jarring even over rocks. The 48V 15AH battery is a game-changer: I can ride 40+ miles on a single charge for my daily commute plus weekend trail adventures, and detaching it to charge indoors is so convenient. Assembly was a breeze too—only took 30 minutes since 85% was pre-installed. The LCD display is easy to read, and the dual disc brakes give me great peace of mind. Worth every penny for a reliable, powerful e-bike! 5/5 stars.

At first I was a bit skeptical, but after seeing generally positive reviews, I decided to purchase this. DEFINITELY worth the $658.48. It looks aesthetically appealing. Very fun way to commute around, tires are strong! The seat is super comfortable. The battery is fast charging. It’s easy to build. You just have to follow the directions.. I wish I could give this bike more than five stars! I’m planning on upgrading to a dual battery
