ElliptiGO bikes are great climbing machines, mostly because the whole system is designed for the rider to use his/her weight to power every stride. In fact, climbing is probably the best thing our bikes do. Because the ElliptiGO 11R has eleven speeds and the 8C has eight speeds, the rider can select from several gears on these models that will enable him or her to climb steep hills comfortably. The 3C model is designed to handle flats and climbs ranging up to 5% in grade like rolling hills, sloping climbs and freeway overpasses. However, if you live in a hilly area with some steep inclines, the 8C or 11R may be a better option. Click here to see a video of how well ElliptiGO bikes perform.
