Love this product.

This case along with the Wahoo fitness app is the best combination for a bike computer. I have traded in my Cycle Ops Joule for my iPhone 4 with Wahoo Fitness app and bike case. I use this with a Quarq power meter, Quarq speed sensor and a CycleOps heart rate monitor. I have never had any problems. I love the screens, they are clean, very clear even in sun light and it has much more detail then the Joule. I have gone through a ton of apps for Android and iPhone and this is the best all-around combination for a bike computer. oh.. and the upload to TrainingPeaks is really nice as well.


I love the Wahoo Bike Case

I have been shopping for a bike mount for my iphone 4 for a while. Everything I found was subpar. This really is the best, highest quality bike mount out there. On top of the bike mount being top notch I had to contact technical support, for a minor issue they were very friendly and helpful. Customer support is key for me, don't support me and I'll look elsewhere. Looks like I will be buying other quality items from Wahoo. Thanks for the great product and help Wahoo

If you're going to carry your iPhone with you anyways...

Great case. Haven't had a fall yet but seems very secure. ANT + receiver works as advertised. Sync easily with Garmin heart rate strap and the Garmin speed and cadence monitor. Works like a charm. No problems with dropped signals. It has been reliable providing valuable information. Makes riding on rollers in the winter so much more fun and interesting. Download Wahoo fitness. It's free! Gives you all the info you need. Works better than other apps.
