This was the last silver frame tidal force bike from Oatnet. I used a 9C 10x6 rear motor. My previous bike had an early Ampedbike front 7x9 winding, I think they were 9c's then. Big difference in many ways. The top speed of course is much better, however, it is a dog on the hills. The first bike with 7x9 was great on hills even with a 36v battery. Also the rear motor is a juice hog. I am using the same 36v10ah battery and I got about 20 mile range on the 7x9, pedaling most of the time. The rear motor is only good for about 13 miles. I guess a larger capacity battery will be necessary in the future. However, I really like the extra top end speed and the bike handles really well. I have a Dart 3 front shock which is a much better ride than my previous no front shock bike.
Thanks to Oatnet for the great deal on the frames and I would like to express my appreciation to all the other Tidal Force builders who have posted their experences as well as pictures. All of the posted info gave me a lot to consider in my build and helped me make it a fairly good experience. I am definitely not as handy as many of you and my workshop is pretty basic. However, I am really pleased with the way the bike turned out. Thanks again. Now I think I am off for a ride.
