Key Features

We're Introduced our DUETT series and what's different from the folding e models on the market. 

You can find out 20-inch folding electric bikes easy but most of them use a Hub motor as a drive system. There are a few problems.

  1. The frame design for hub motor is simple and easy but it has potential safety problems. (The motor drive section will break the dropout or frame even fork after long periods of used)
  2. Hub motor system have to extra connect with controller and it must with external to a lot of wire and them not special design for this system and the wires easy to have problems, or battery fires, even explosions. 
  3. Most hub motor for the cost of savings reason and the controller, firmware and display and batteries them not do communication and its often caused the battery power, and the display the power meter cannot match, can't judge the information of motor system or the battery failure.
