Thanks for the info. I just ordered the 250/NiMH. If I'm not mistaken level 3 is 100% assistance? 1=25%, 2=50%, 3=100%, and 4=200%

I'm doing a 12.5 mile commute that is down hill one direction and up hill on the return. I'm suspecting that I'll mostly use the assistance up hill probably at level 2. My bike with loaded panniers, the bionx system, and me is around 300lbs.

so you are getting 25 miles with pretty minimal effort if I'm not mistaken (on level 3) How much does your bike weigh rolling down the road including you? How far can you go on level 2?

This is great info thanks.

Thanks
