Customer Stories
Battery capacity & Price
- My Great Challenge
This is an incredibly cute-looking electric bike. The TST Flyer 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 $989. You could have your first electric bike in life with that!
