So far we don't know how tough they'll hold up riding in snow and being exposed to salt. We have had a number of messages from people in cold environments, so it's definitely a big deal. Wet and cold will be of no issue but the impact of snow/salt on the rings over time could be another story. We are taking comments like this into account as we finalize the design. We're on it.
This is a great suggestion and we've gotten multiple requests from motorcyclists and wheelchair users. While we do not currently have a design that is compatible, we do realize that a future design for use with motorcycles/wheelchairs is a huge opportunity and we'd love to achieve this goal in the future. We'll be sure to let you know if one of our future designs will be compatible via our kickstarter project page or http://revolights.com/. Please stay tuned.
There has been a lot of feedback regarding the stationary illumination pattern and we are currently looking into other options, including solid arc illumination. We'll be sure to provide an update when we have reached a final decision.
The Revolights bike lighting system can only be installed (and uninstalled) with your wheel removed. Therefore they are not, in the current v4 easy to steal. They are only as easy to steal as ones wheel. We consider thievery a certain design priority.
Currently the Revolights bike lighting system is developed for Road and Hybrid 700 series rims, (aka 700c aka 622mm). If you don't know your rim size please email any one of the founders with any numbers you can find in your tire/rim and we will figure it out! They will be adapted to more sizes in the future, this is just our initial target.
v4 includes a magnetic timing mechanism that calculates your speed and, based on an algorithm, maintains the illuminated arc size and position. There are plans to incorporate an accelerometer into future designs as a more robust solution.
