    BikeRay pre-delivery test

    BikeRay USA do get pre tested Ray light kits from manufacture with very few issues, less than 3-5% with some light issues. Yet we re-run many tests on battery life, battery safety, Charger safety, light switch safety, connector safety etc., before we deliver the lights to customers.
    We charge and discharge lights to go with 2-3 cycling times on batteries, Check and triger the switches over 20-40 times, check chargers at list 5+ times, check all rubber seals for any issues, then we re-package them to ship out.

    We rather spend extra time & money to test them before selling them.

    Here we have some pics when we were testing battery life(up to 235 minutes) as you can see at the last pic, (right side), switches and of course the chargers were tested and used to charge these batteries.

    We use fan to cool the light heads, since they come with automatic heat protection board, if light head gets too hot, it will go to low mode. So, this will prevent to go to low mode.
    Nothing fancy but very effective.

    nice to know they are checked in house before you ship them!

    Hi Nick;

    Believe or not, I was, and I still am a bit skeptical with Made in China thing, just like everyone else.
    Though we haven't have many issues with the quality, we feel more safer~?, doing this extra step.
    It does cost us more on electrical bills, time involved is incredible, at least with 2 battery cycles, you know...... plus man power......lol
    At same time, it secures us not to sell any light kits with issues. And it gives sefety of any possible issues of misuse from customers.
    Though the test is a little primitive way of doing it, but it works just as testing out on the field.

    As at the fat tire festival at OMBA, sold more than 80 units but had not one single issue but a lot of compliments over other brands.

    Playing devils advocate, but two standard cycles would not identify any potential latent failures. We normally cycle electronics thru a burn in cycle which consists of 8 hot cold cycles allowing the temps to stabilize in each state before power is applied. If the component is going to fail it normally does between cycle 5-7.

    Another question is were the components up screened for the first batch? This is an effective means of sorting the components for a more reliable and stable build allowing it to pass a first article inspection, however once passed sub par components could be swapped in resulting in low performance. This is common practice for vendors out of China allowing them to maximize their profits as long as the client does not notice. Once there are complaints they will take one or two steps back to where it woks without issues, but still lower performance. This requires that all components sourced be screened for sub par or even counterfeit ICs. Internal components should be screened by both date and lot codes. If there is ever an issue then you would be capable of tracking failure trends.

    Would suggest deliding the ICs but this would be an expensive step that the customers would not want to pay for.

    For the batteries have they been tested IAW UN standards, Sub-Section 38.3 including:
    - T1: altitude simulation
    - T2: thermal test
    - T3: vibration
    - T4: shock
    - T5: external short circuit
    - T6: impact
    - T7: overcharge
    - T8: forced discharge

    Depending upon the lithium content in the packs testing could vary slightly. Testing of individual cells is not a viable means of securing safety for the end customer. When assembles in a pack format the battery dynamics change. This test is important as unstable cells do result in the pack venting with flame damaging what ever is around them. Granted chargers and understanding around Lithium cells has matured, yet still does damage if the circuit protection gets damaged.

    Just a few thoughts right off the bat.

    Hi Cajun Rich;

    The lights on these pics are Ray-II.
    Same tests are done to all bikeray lights before delivery.

    Nice to know your testing them prior to delivery. Reason for last post is that with Military electronics you would not believe the stuff I've seen come out of China. One build was so over loaded with counterfeit parts that the company supplying them got quite a bit of attention from old uncle sam and not the nice type either. Know these are not going on F-15s, but still is nice to know what your dealing with when components are coming from an overseas vendor.

    Hey crux;
    Thank you for the sincere comments on quality issues.
    One of the reason why it took us such a long time to release the product to the U.S market, is same reason. We tested all and every components for several months and made many changes and also traveled to manufacture to make right corrections.

    We got into heavy arguments so many times, we almost bleach the contract at least 4-5 times. We couldn't agree on volume sales as manufacture was pushing us. We rather drop the contract and forget about all. But had luck and could convince them to seek into quality than quantity.

    Since than our cost went up, but we finally could manage the quality issues with them.
    Now they are coperating so good, it is hard to believe its coming out from China.

    Now we are confident to put our name with BikeRay brand and don't want to ruin it because of quality issues.

    Thanks again~!

    We are arguing with ups.
    They haven't updated thier traking on our shipment.
    What we were told by one of their agent is, due to high gas cost, they are trying to fill the plane and that is what was causing so many delays not just on ours but on so many companies too.
    I will send you pm tomorow with more updates,.

    Sorry for the delay.
