Notes      

  • Please check the product size before ordering to make sure it fits your needs.
  • For the 36V product, 3 12V lead-acid batteries(not included) need to be connected in series to form a 36V voltage, or a 36V lithium-ion battery(not included) can be used directly.
  • During installation, it is necessary to adjust the angle to ensure that the front and rear wheels are in a straight line. If the angle is incorrect, it can be adjusted by adding or removing shims under the mounting plate at the axle position. If the front and rear wheels are not in a straight line, the chain will tilt to one side, which may cause the force to tilt to one side all the time when the flywheel rotates, making the flywheel easily damaged.
  • It is recommended to use batteries with a capacity of 15Ah or more.
  • Please note that this item is for a bike that uses a hub diameter of less than 1.42in.
  • Please note that this item doesn't include batteries or chargers.
  • Please allow the slight color difference caused by the shooting light and 1-3cm error due to manual measurement, and make sure you do not mind before ordering.
