i! I have a Trek Powerfly 7 (2017) 500W/Bosch Performance CX mid-motor, bought last April. In the past 9 months I have done 3,145 fault-free, mixed terrain miles (at an overall average speed of 15.2 mph) and it is still running perfectly (although chain replaced every 1,500 miles and brake pads replaced at 2,500).
The range is about 35 miles because this is mid-Wales and the terrain is less than flat! On the occasional, flattish route I have achieved 44 miles. Be warned tho' - the Bosch motors have a crank to pedal rotation step-up ratio of 2.5:1 which means your bike, with an all-up weight (including rider) of 100kg, becomes 250kg when the battery is exhausted!
I toyed with the idea of a dongle as I do find 16 mph a bit limited, but as the bike cost £2.5k I will wait until the Bosch 2 year guarantee period is over!
