Did 18 miles on a mixture of B roads and country roads this afternoon. It was a bit nippy with a 15 mph wind from the East , but motorcycle gloves and two pairs of trousers kept the cold at bay . I only saw 3 other cyclists and two horse riders and my battery powered horn got me noticed without the horses bolting . At the end of my trip I stopped to watch a Thomson 757 taking off at Cardiff Airport and it was airborne in half of the 8000 ft. runway into the stiff wind . It was going to Chambery , perhaps the weather was warmer there ! On the way back and up the slope into the wind I only used medium assist and finished the trip with 3 of the 4 diodes still showing on the handlebar unit . I carried my Holux GPS which registered 17.78 miles ,max. speed of 24 mph down a slope , my height variation was 187+ or- 62 ft , I had used 1261 cals and saved 14.9 lb. of CO2 ! I must admit these Ebikes certainly double you normal cycling range for very little effort .
