1. Friction Resistance Spin Bikes

Principle of resistance adjustment: The resistance is adjusted through the physical friction between the brake disk and the flywheel. Generally, this adjustment mode will generate noise due to physical friction, and the resistance change is not smooth enough, so the adjustment range is small.

Disadvantages: The accuracy is relatively poor, and the adjustment is prone to be over-limit or not enough. Another disadvantage is that the flywheel will generate inertia during riding. Sometimes, if you do not pay attention to it, your feet will slide away from the pedal easily, causing certain danger.

2. Magnetic Resistance Spin Bikes

Principle of resistance adjustment: Magnets are installed on both sides of the metal flywheel, and the resistance is adjusted by controlling the distance between the magnet and the flywheel via a wire motor. The particular strong magnet material is used to realize a balanced state of no friction and non-contact suspension between the large flywheel and the magnet. The movement resistance can be controlled through the distance adjustment and the resistance level can be adjusted more accurately.

Advantages: no friction, ultra-quiet; low loss, no change of accessories for life; high smoothness, never getting stuck during riding; automatic resistance control, no manual adjustment needed; linking with sports app, various programs.

3. Electromagnetic Resistance Spin Bikes

Principle of resistance adjustment: mainly includes the magnetic effect of electric current and Faraday’s law of electromagnetic induction, namely, the process in which the conductor in the magnetic field cuts the magnetic line of force to generate induced current, and the magnetic field creates ampere force (Lorentz force) on the live conductor. If the bike keeps powered on, the user experience is better. It is the highest-end bike product in the market.

Compared with ordinary magnetic resistance bikes, except for the quiet effect, automatic resistance adjustment, and more smart programs, electromagnetic resistance spin bikes also have the following advantages:

1. The adjustment speed is faster. The adjustment from the highest gear to the lowest gear needs less than 0.1s, while the wire motor takes at least 3s-5s.

2. The adjustment granularity is finer. The resistance adjustment can be divided into 1,000 gears, while the wire motor can achieve 32 gears at most.

3. The power accuracy is higher, up to ±5%, while the wire motor has poor accuracy, generally ±20-30%.

MAGENE smart spin bike is a quiet and compact smart bike specially designed for fat burning and trimming, with electromagnetic resistance perfect for the household. The smart bike adopts the EMS patented electromagnetic resistance technology independently developed and realizes accurate power calculation and control through the multi-dimensional power compensation algorithm. In comparison with traditional spin bikes, it features a more smart experience, richer programs, and more scientific exercise methods. Moreover, MAGENE has cooperated with several world-renowned software service providers so that the bike is compatible with more than 20 mainstream cycling and sports apps.
