 Orp recipients,

The first batch of Orps are shipping and I think a few things need to be further explained as well as I want to point out a few Orp peculiarities and special features.

A. Please  have a look on the inside of the box for the "no need to be able to read" instructions.

 If you can't read, get a friend to read this Orpdate to you.

 I may reference the numbered steps in the expanded explanations below.

B. #1 Mounting your Orp 

Your Orp needs to face forward on your bars. If you have road bars you may want to put your Orp on the Left side of the stem so, if you need to brake. you have a hand on the rear brake.

If you have straight bars where you can actuate your Orp with your thumb and still have a hand on the grip +  brake and your orp is facing forward well,  great!

Orp was designed to sit low on the bar and was built on a specific diameter. If you need to put your Orp on a less than a  25mm diameter bar you'll need to use the SHORP {shim for Orp} to fatten up your bar

Make sure  The SHORP is at a comfortable  room temperature and has remained clean. Wrap your SHORP around your bar as shown in the instructions and make sure  to stretch it on the bar. Release the adhesive cover and  press all over the adhesive area  to make sure you have a strong "Pressure Sensitive" bond. The SHORP need only be stuck to itself.

C. #5 Anti Dooring Mode

Make sure your Orp is powered up and simultaneously press the power mode button and the WailTail down. This will result in a strobing loud 96dB sound. The idea here is  this may be useful in alerting recently parked drivers of your presence when you are on a tight street lined with parked cars and your  other side is a river of too fast moving traffic. It's too late to switch routes so, hopefully these recent parkers will hear you coming and check their mirrors before opening their doors. 

D. #9 Charging your Orp

One peculiar attribute  of Orp is that, sure when he/she is fully charged you'll get a green light, but if you leave your Orp  plugged in, that green light will start depleting the battery and the light will turn red.

E. What's that black cap on the right side of my Orp?

That means your Orp is Remote Ready! We added this feature post campaign  to make Orp better. If you are  putting your Orp on a road bike, your Orp may not be under thumb for quick horn actuation as your hands are up on the hoods. We've designed the REMORP  and it's in the works. This will allow you to put your  dual decibel Horn actuator wherever you want!

It's super intuitive as the first push ignites the friendly sound and a harder push gets the loud sound to blast.

This video starring Calen's hands, a Snot Green Orp and a rough physical prototype of the REMORP explains the concept. The cord is too thick and too short in this prototype.

      The remote "remorp" idea sounds great! Any idea on a timeframe? I'd be 100% down for buying one.

    2. erik didriksen on March 14, 2014

      Will there be a separate campaign for Remorp or do you plan to sell it as an accessory/bundle in the future?

    3. Werlindo N. Mangrobang on February 7, 2014

      Got mine yesterday! Loud and bright...can't wait to try it out on the road. Nice work!

    4. John D'Alessandro on February 7, 2014

      Got my Orp yesterday in the mail.
      Can't wait to try it out, but with 3 feet of snow on the
      ground here in Minnesota, maybe I'll just wake my wife up
      with the horn....ok maybe not

    5. Lars Viborg on February 7, 2014

      Best news EVER :-) Can't wait for to give it a try here in Denmark.

      Remorp sounds awesome. Out for my inaguaral ride with ORP and that was one thing I noticed. And man, you've already solved it!!

      Great work!

    7. Tory Orzeck Creator on February 6, 2014

      Also remember Orp needs to be removed to be recharged . If you can park your bike inside where it will not be vandalized that 'd be best. I guarantee if it were left on you bike, vandals would twist its little body off.

    8. Tory Orzeck Creator on February 6, 2014

      You guys need to follow the instructions.
      First Power your Orp down while its still mounted on your bike. Otherwise, you'll get the horn blast.
      Next pull up Orps tail like you're checking whether you have a a boy or girl cat
      Pull down the USB Flap and pull up to remove the tail from the cradle.


      Yeah, at first its a little tough to get Orp on and Off but it will get easier as you get used to the amount of force required.

      And...holy cow but its the first Orp!

      Sorry Tory. I read your update without checking first for answers to my same questions on the comments list. I see that you answered my questions over there. Thanks.

      Also it would be helpful if there were a way to attach it securely to the bike so that you did not have to remove it whenever you park if you live in areas of high theft. I noticed those two little holes below the tab for pulling the device off. I'm curious what they are for. I had been hoping it was a place to insert screws and attach the device more permanently but on opening it I see that there is no place to receive those screws so far as I can tell.

      I agree with Taylor that it would be nice if it could be removed more easily. One problem is that it is almost impossible to remove it without it making a lot of noise.

      Got my Orp yesterday, totally worth the wait! Great product, well done on the packaging as well. There has been a cold snap here in Seattle, for the next models I'd suggest a tab that is a little easier to remove the Orp from the bike. I like the simplicity of the design, but it is a bit hard to grab with gloved or numb fingers. Thanks again! Super excited for the Remorp!

    13. Paul J. McMurdie II on February 6, 2014

      I use a road bike exclusively, and am really excited about this REMORP demo. First I've heard of it. The combo of ORP+REMORP will be a huge improvement over the delicate bike bell placed near the center of my bars. Can't wait for ORP to arrive! And how can I go about testing a demo of the REMORP??

      Just received my ORP and before I mounted it on my bike, I took to our Miami Inovation Fund meeting- All my tech angel investor friends were very impressed with the product and the innovative packaging and use of that container for no read instructions- Bravo! I ride early in the AM and this solves my problem I'd seeing and being seen from the front- perhaps RORB should be added to your product line with a red strobe to mark your bike from behind?
