I also use the Open Cycle Map layer in the Russian Military Maps, Pro version ($11). You can try the free version first. The Pro version allows you to download a larger map area to save in memory for use later. But, this larger map area is still tiny compared to the Maps With Me where you download entire states at at time. The Russian Military Maps app is much more memory intensive than the Maps With Me app. But the maps include bike trails. It took me a while to figure out the intricacies of how best to use this app, but once I did I was very happy with it.

I also loaded GPS Test. One of my GPS apps stopped working, after loading GPS Test it started to work again. Not sure why but I am keeping it loaded since it was free and there is no disadvantage to having it loaded.

With these mapping apps, you will want a good size memory card plugged into your tablet.

For biking, I still prefer a stand alone GPS unit, but these apps are pretty neat to have. My Garmin GPS units have such a tiny screen that it would be impossible to plan out a route, a 7 inch table would be a lot better where I have wifi access.
