MOSUNY exercise bike for home utilizes a European Union-imported high-quality bike flywheel to minimize friction between the flywheel and the drive belt. Additionally, we utilize a braided rope to encircle the solid elastic band, rather than a simple hollow rubber band, to further reduce the friction and noise during arm exercises. This makes this exercise bike the quietest one, with a noise level of less than 10 DB while in use.

Our home exercise bike allows users to find the optimal resistance intensity for their needs, whether they are elderly individuals undergoing rehabilitation training, office professionals seeking to improve their fitness, or fitness enthusiasts seeking to build muscle.
