It's not suitable for use as a bike computer.
I ordered an 810 with routing because I didn't want a larger, more power hungry Edge 1000. Hopefully I won't have crashing problems with Open Cycle Map maps; although if I do before the ELEMNT gets debugged will probably try an Edge 800 which seems more reliable and is less likely to lose a ride when it crashes.
Here's the thing, I have an S4 with an aftermarket battery in it, the Anker 7800mah, up from the stock 2600 and thus a larger case that fits around the battery. Therefore, I can't use any 'phone specific' case since the battery will not fit a traditional aftermarket case that may be provided with a mount. Secondly, it is no longer the traditional size of the S4 since there's about an added 1/2'' of height or depth to the phone.
I will get 8+hrs out of a charge running just about everything all at the same time. However, how the heck am I to mount it is another question. It looks as if the Nite Ize might actually work, I will have to give that a go.
I think I would be better suited to pick up the Bryton Rider 310 GPS for something like $150 or $160 with heart rate monitor and cadence monitor included that will give me heart rate, cadence, speed, pretty much everything except for turn by turn 'figure out on the fly' navigation (that I can get from my phone) with a decent handlebar mount.
Yeah, I may look like a dweeb for having dual electronics up front, and yeah I may be adding more weight but I think that'd be the best, most dollar conscious application.
