The present disclosure relates to the technical field of fitness equipment, in particular to an electric bicycle available for fitness and an interactive system.
The existing electric bicycles are generally only used for traveling, but is not available for fitness.
If the existing electric bicycle is used indoors as sports equipment, a special bracket is required. Such bracket needs to add extra resistance outside the wheel, or remove the rear wheel and directly connect a resistance device to a bicycle chain, so that the user cannot miss his/her step, thus achieving the fitness effect.
However, both methods have disadvantages.
If a resistance wheel is added to the outside of a tire, it is necessary to squeeze the rear tire with the resistance wheel, resulting in tire deformation, loud noise and tire wear during movement.
If the rear wheel is removed and the resistance wheel is directly connected with the chain, the disassembly process is more complicated.
The applicant finds that there are at least the following technical issues in the prior art: when the existing electric bicycle is used as fitness equipment, an external damper needs to be added.

An interactive system is provided, comprising a computer, a display device, and the electric bicycle available for fitness according to claim 7; wherein
The electric bicycle available for fitness provided by the present disclosure comprises an electric bicycle body, a front wheel bracket 1 and a first controller 5.
The electric bicycle body comprises a vehicle body 2 and a rear wheel bracket 3. The rear wheel bracket 3 supports the vehicle body 2 and makes the rear wheel in a suspended state, so that the electric bicycle body can be used as indoor fitness equipment.
The rear wheel bracket 3 is provided with a color-changing LED lamp and a sound box. The vehicle body 2 is electrically connected with the rear wheel bracket 3. The battery of the vehicle body 2 is used to charge the rear wheel bracket 3, so as to provide sound and light accompanying movement for users in the process of fitness and encourage users to complete fitness. The rear wheel bracket 3 can also be charged by an external power supply.
The rear wheel bracket 3 is provided with a first socket 31 and a second socket 32. The first socket 31 and a second socket 32 are both screwed with the rear wheel bracket 3. By rotating the first socket 31 and the second socket 32, the rear axle of the electric bicycle body can be supported between the first socket 31 and the second socket 32.
The front wheel of the vehicle body 2 is fixed on the front wheel bracket 1. The front wheel bracket 1 is provided with a steering and aligning structure 4. After the front wheel bracket 1 deviates from a designated position, the steering and aligning structure 4 can exert an acting force so that the front wheel bracket 1 returns to the designated position.
