The Custom Sport Rider Heavy Duty is a modified version of their regular rack and will fit 2 ElliptiGOs or 1 ElliptiGO and 1 bicycle. Remove the front wheel, then place the ElliptiGO so the rear wheel is in the u-shaped wheel holder and lock the fork to the fork mount. The fork mount secures the ElliptiGO to the rack and Velcro wheel straps secure the rear wheel in the u-shaped wheel holder. The rack folds easily when not in use. Fits 2” hitches. For 1.25" hitch rack solutions, please email us at info@elliptigo.com.
