I know there are these triangular shaped devices, that you mount the back of a bicycle to, and it converts the bike into a stationary exercise bike…I think there are different types of machines…ie, one may use a belt for resistance, one may use magnets, etc.

Does anyone have any recomendations? i want something good, but i don’t want to pay an arm and a leg.

Thanks
does anyonbe have experince with the differences between magetic, fluid, etc?
