Who should buy it
The T20 is for riders who value a compact fold and a standard pedelec experience. It is not for long commutes or heavy cargo. Consider it if your trips are short and you have a place to store it folded.
- You ride less than 16 km per trip and can charge at work or home.
- You need a bike that folds small for storage in a tight space.
- You prefer a simple hub motor with no throttle.
Look elsewhere if you need more range or a lighter bike. The T20's estimated range is 18 km, and its weight is 34.5 kg. Many folding e-bikes offer more range for less money.
