Abstract

A device for demonstrating and testing electronic meters for bicycles including a body portion having a slot, a rod mounted on the body portion, a plurality of seats mounted on the rod, a first magnet fitted on the body portion, a handwheel partially pivotally fitted in the slot of the body portion, a second magnet fitted on a the handwheel, and an electronic testing device disposed within the body portion and operatively connected with the seats, whereby the device can be used for demonstrating as well as testing electronic meters for bicycles.

Claims

1. A device for demonstrating and testing electronic meters for bicycles comprising:

a body portion having a slot;

a rod mounted on said body portion;

a plurality of seats mounted on said rod;

a first magnet fitted on said body portion;

a handwheel partially pivotally fitted in the slot of said body portion;

a second magnet fitted on a said handwheel; and

an electronic testing device disposed within said body portion and operatively connected with said seats.

2. The device for demonstrating and testing electronic meters for bicycles as claimed in claim 1, wherein said rod is in shape of a handlebar.

3. The device for demonstrating and testing electronic meters for bicycles as claimed in claim 1, wherein said electronic testing device will show digital value to compare with value shown on electronic meters to be tested.

4. The device for demonstrating and testing electronic meters for bicycles as claimed in claim 1, wherein said electronic testing device applies a formula S=L/T, wherein S represents speed, L circumferential length of bicycle wheel, and T cycling time, and will automatically calculate value S by keying in L and T thereby enabling a user to compare the value S with a value S shown on said electronic meters.

5. The device for demonstrating and testing electronic meters for bicycles as claimed in claim 1, wherein said electronic testing device is provided with a bingo game therein which will show preset contents corresponding to revolution numbers of said handwheel when said handwheel is stopped.

6. The device for demonstrating and testing electronic meters for bicycles as claimed in claim 5, wherein said bingo game can be set to show numerals or characters.
