Back to the original question of Interceptor vs. Commuter and I feel that I am qualified to answer as I have have both and if I could have done it over again I think I would have gotten two Interceptors. Why ? I feel that the Interceptor is a better built bike. We picked them both up back in FEB-2015 and have a bit over 300 miles on them. So far no big problems but a few small adjustment issues. First, I was unhappy with the blue on the city commuter as its one of those colors that depending on the lighting its can be blue or purple. I think my wife was disappointed with that. We ride these only on rail - trail so no road use but it seems that the commuter rattles / clicks and makes more noise as we go along... Also, I have to adjust the break cut-off switch on the commuter from time to time. The only issue with the interceptor is that it seems to forget some of the trips we take and I need to contact pedgo about that.
We got these with the highest battery capacity and the starting price of the commuter was much lower than the interceptor but ended up being the same with the upgraded electrical system. I am a big guy at 265 lbs and I feel more stable on the interceptor vs commuter but that's probably the tire size.
Range wise they are great. Our longest ride so far was 35 miles on pedal assist 2 and had better that 50% battery capacity left. They was a rail trail with slight grades. We ride 25 miles near our house weekly and keep it above 80% on the capacity so we are very impressed. Out of curiosity I measured the cost to see what it takes to charge two batteries at 11 cents per KW with a 50% discharge so its 7 cents. Not bad to go 70 miles (2 bikes) and only cost 7 cents ! If it ever stops raining here in Pennsylvania we have some 50 and 70 mile trips planned.
To sum it it.. Great bikes... No big problems yet... And someday may just trade up the commuter to an interceptor.
