I researched dozens of e-bikes before choosing this one, and I’m so glad I did! The build quality is top-notch—aluminum frame feels durable, and the waterproof battery gives me confidence riding in light rain. The 1500W motor provides plenty of power for hills and rough terrain, and the 30MPH top speed is perfect for getting around town efficiently. I love that it’s not just a “throttle-only” bike—pedaling with the 7 gears lets me save battery and get a little exercise too. Assembly was straightforward (the instructions were clear) and took less than an hour. The ride is smooth and comfortable, whether I’m on pavement or dirt. It’s passed every test I’ve thrown at it, and the 5-star rating is well-deserved. If you’re in the market for a versatile, reliable electric bike, don’t hesitate to buy this one!

well, I got home at 530p today and my 10yr old (passenger only!) and I had dinner and were out on the bike cruising around the town by 7p its SO much fun - its super powerful so with a passanger, be careful on take off lol I am ordering a back rest for extra passenger support/comfort. came with pegs and the back seat - XL 10yr old said its super comfy!! and fast even with two adult size people. instructions are easy to follow and comes with ALL the tools in a little pouch which I ziptied under the seat as an emergency kit after completing the build. - which, its great quality materials. it looks great, sleek. did a few months of research before finding this company and let me tell you, I absolutely love this bike. its currently 11p lol - I plan to use this to commute to work about 1.5miles away from home so I guess I'll update in a few weeks/months but so far amazing and 100% worth every $!

The electric ebike R9 it's very good product

I liked the look of this and having received it I can say: it matches the pictures. Good solid build and easy clear instructions on assembly. Once put together (in a little under an hour) and running it was certainly comfortable to sit on and pedal around. The electric power assist makes me wish I lived within biking distance of work so I could use this everyday. And electric power alone is exhilarating up to 30 mph! So much torque!! Now I’m just waiting for the weather to warm up here so I can take it off road and really push this thing. Might have to get 1 for my wife too!

I purchased TST R9 when I open the E-Bike it was very easy to put together followed the instructions from the video and was together 30 minutes later. I have had it for approx 2.5 weeks have put a hundred miles on this I use it to goto work shopping and fishing I have had no issues with this product I live in N. Florida whe where we have a lot of hills does not slow down it keeps on going battery life is great. And this is what really shocked me with this company a week ago yesterday I was going home from a Conference at work and I ended up having a wreck and taken to the hospital it was 2 days after I got home before I saw the bike in light where I could see any damage after the wreck I noticed that the H style handlebars were bent and I contacted toe company and they asked me for pictures and when submitted the company offered to send me one w/o charge. This company stands by their product I highly recommend the TST R9 as far as I am concerned they have a loyal customer here.

Bikes good for the money. Craftsmanship is ehh. They stripped the bolts in the factory so can't install front fender. Also they misaligned the welds for the seat so can only put half the bolts in to hold the seat on. Bike description claims it has hydraulic disc breaks, this however is false. They are not hydraulic and they struggle to stop the bike. Also missing pieces in the tool kit so unable to install the derailer guard as well. But for a cheap ebike it seems to meet my expectations.

I recently bought this TST ebike and it's amazing. It was easy to assemble and after connecting my phone I was able to unlock a faster speed. It is very safe and comfortable and the battery lasts a very long time. I will be buying another one for my son.
