This is designed for use with Yakups brand rack to aid in loading heavier bikes than a regular bike. We have a hoist arm that mounts behind the rack and will allow some ease in loading heavier bikes. Not recommended for bikes over 60 lbs. Bike's that are this heavy may still require assistance from an extra person when loading.
The wheel strap goes on the wheel and is left on when travelling. If you order this separately from a rack you will need to do some drilling and assembly to affix it on your rack.
