Now it is official, I commute to work on my e-bike regularly. For my third ride I chose highest assistance level available on my bike, the BOOST. As with sport level, I had no problem staying above 20mph, however this time I arrived to work with 60% battery power and got back home at 40%. With sport level I did worst , however it was my very first ride and I am not sure if battery was at 100% or a little less. Ride to work took me 35 minutes, even on the highest assistance level. I was disappointed that there was very little improvement in arriving time, maybe 3 minutes compering to standard level of assistance. I could feel bike being more snappy and getting me over 20mph faster. Overall bike is perfect for my commute, I am happy with the purchase I've made.
