    Dear E4C Staff, I’m posting based on the understanding that these comments are visible internally at E4C and not to general visitors to the site. If my understanding is incorrect please delete as these are intended to help E4C refine the comparison/evaluation.

    Comments in order:

    Manufacturing: chairs are manufactured in China and shipped flat-pack where they are assembled in-country

    IP: not patent protected. blueprints not available to general public.

    User Provision Model: add “Motivation emphasizes training in safe and appropriate wheelchair provision and works to connect local partners with WHO-approved training courses”

    Distribution to date: Unknown. In volume production since 2004 at estimated 1,000-10,000 units per year (this is my best guess of range based on known clients. I’ll ask them to share actual number but in my experience they are not public with this info)

    max rider: ok

    seat width: ok

    seat depth: Motivation material says adjusts for users measuring 43 to 54cm buttock to back of knee

    adjustable seat: seat is settable permanently with tools at time of fitting.

    Frame type: rigid not folding, but parts can be removed for transport/storage

    Seat angle: you could say “90 degrees seat-back with 8 degrees of adjustment”. as written it is unclear seat to vertical or seat to back? if you mean seat to back angle, that is adjustable by 8 degrees on this product, I believe 90-98 but they do not specify.

    footrest ht ok

    repairable ok

    chair weight: should be 22kg. 25kg includes packaging, extra mat’l typically discarded after fitting.

    Fatigue tested: meets or exceeds ISO 7176-8. Tested by 3rd party to 200,000 cycles of Double Drum (endurance test subset of 7176-8). Tested by manufacturer to 400,000 cycles.

    Replacement components: the link connects to pdf with multiple manufacturers products

    vetted performance: current or past long-term customers include Latter Day Saints Charities, Handicap International, Walkabout Foundation, United Cerebral Palsy / Wheels for Humanity

    Complementary technical systems: Customizable contoured multi-density pressure relief cushion included with every chair (this is worth mentioning, it’s safety critical and WHO recommends inclusion, but may not be distributed w all manufacturer’s wheelchairs
    Optional handcycle attachment available.

  3. E4C.COMMENTS says:

    Matt McCambridge says:

    This reads as if someone with knowledge and interest in controlling electric motors went looking for a use for them, and decided on wheelchairs, without knowing anything about wheelchairs–either about the human factors or the mechanical issues. That is OK provided this person will partner with people/organizations who understand those things. they mention on the next page their partnership with the rehab hospital, if they truly allow these users to drive the design they might come up with something good. they should also involve people familiar with wheeled devices which survive in that environment–not necessarily wheelchairs, better perhaps to learn from rickshaws, bicycles, things which survive the terrain.

  4. Robert Hauck says:

    Given where these units will be deployed effective quality control is essential. For any unit to contain manufacturing defects or to arrive ‘dead-on-arrival’ at the customer is absolutely unacceptable. This requires both process control and appropriate testing during manufacturing as well as final assembly and test to ensure product quality. “checking In” quality after assembly will not be possible.
