Customer needs, product requirements
Davey (is sweet)
The Bike Lift has several interesting features that empower the user to store their bike safely and neatly. First, the lift provides the customer with a designated spot where they can always store their bike. The customer never needs to figure out where to put the bike to keep it out of everyone’s way; the lift establishes a consistent, isolated location for storage. This is desirable for the user because it is one less thing they have to worry about after an enjoyable ride.
Also, the safety and ease of use features are pleasing for the consumer. The pulley mounts are secured dependably into the joists of the ceiling or into an unfailing 2 by 4. These mounts house the rope and pulleys which provide the mechanical advantage for lifting the bike. Customers love this aspect of the lift because it is not straining to lift the bike well out of harms way. This product meets the customer’s requests because it provides an all-purpose solution to enable users to store their bike in a protected, organized and out of sight manner.
The product does not have a multitude of complex parts which require heavy analysis, which is convenient. In order to satisfy accurate operation, the product must be comprised of strong, reliable materials. The screws, mounts, pulleys and hooks must be made of trustworthy materials. Also, the product must be installed correctly which implies that the installation directions must be unbelievably clear and concise. The rope must be of sufficient length so that each customer can operate the lift under their specific storage desires (high ceilings, large bikes, etc.). Lastly, the product must be extremely durable. A user may raise many different bikes, many different times so the product must be reliable and last for a considerable amount of time pleasing each and every customer beyond their expectations.
Explanation of how system functions
Russ and Jeff
After purchase, the first step in using the Ceiling Mounted Bicycle Lift is to install the system in the desired location. A set of instructions is included with the product. However, after reviewing the instructions, we determined that they contain many errors and may confuse the user if they were to follow the directions exactly. Therefore, we have developed the following setup procedure to describe the way a generally knowledgeable user may install it without using the given instructions. The Ceiling-mounted bicycle lift setup wiki page shows how we set up the bike lift.
