any good athletic equipment stores near where you live where you can try different equipment? or an athletic club that lets you sign up month to month or gives a one day free pass so you can try diff bikes? fwiw about a year ago i bought a recumbent lifecycle LC850 RB. tried it out, liked it at the store. hated it after i got home, seemed really jerky motion. i soon discovered it was me who was jerky, not the bike and i needed to have enough meds while cycling. feel a little better after cycling but i'm nowhere near the "magic" level.
schwin recumbents get good marks, i bought the lifecycle from athletic equip store on sale, smaller than schwinn, they assembled, delivered and had 30day return policy. so important to pick a good store. or not.
