I am happy with end result but my biggest complaint is the slow response time to activate the electric motor and the fact you have to hold your thumb in on the button for at least 4 to 6 seconds to switch on. I should have chosen the 30 km battery. I will order the thumb control. The early controller failure a bit disappointing and getting it resolved took too long. As I’ve mentioned before the fact I was originally invoiced in 3 different currencies was strange and caused me to be overcharged. I found the original pedal sensor wheel ran eccentrically ( had a new one made). Delivery was slower than originally promised by 3 months approximately. Controller lights hard to see in sunlight.
