Customer Stories
Battery life & Maximum speed
- Cole & Jay
Outdoors adventure calls for the TST electric bicycle, my ultimate companion, catering to my everyday outdoor exploration needs! It blends the thrill of fishing and the excitement of cruising perfectly. With a top speed of 28 miles per hour, I can swiftly reach the prime fishing spots, and the battery lasts for 65 miles, giving me complete control. With a weight capacity of 500 pounds, every fishing trip goes beyond imagination!
Battery capacity & Price
- Billanddeb
This is an incredibly cute-looking electric bike. The TST Surfer boasts some sharp colors. I love the concealed battery, which has a capacity of 48 volts and 15 amp-hours. A 1000-watt power is sufficient for most people. If you encounter steep terrain, you can assist by pedaling. Not sure if there's an e-bike with that budget-friendly price tag, but for what you're getting, it's great. It offers high value for money, coming in at just $1199. You could have your first electric bike in life with that!
Pedal assist & Weight capacity
- Jerry Tweek
Double the fun with tandem riding! Today, my friend and I are experiencing my big toy together – the TST Dreamer electric bike. It comes with smart pedal assist, giving me a refreshing breeze as I pedal along. With a weight capacity of 500 pounds, I can bring my friend along to share the joy of riding. They're sitting on the back seat, shouting with excitement. We are truly satisfied with this electric bike!
