Love it. The electronic propulsion is perfectly integrated into the mechanical part. Very smooth transition from pedaling alone to pedaling with assist. Did a bit under seven miles today and piece of cake - even the hills. Was averaging 15-20 mph on level road and 10-15 on the hills. Got up to 25 heading down the big hill near my house.
There is a bar graph indicating power remaining and it still shows 100% charge - I'll be using it a lot in the next couple weeks and see how long it takes to get it down to 30%
Back 12 years I bought an electric bike - a red LaFree that cost a bit over $1000. The need to pedal to get assist was OK for a while, but my legs couldn't hack it. Polio can really bring you down the most - best of luck with yours!
