There's cycling groups in Chiang Mai, Thai and foreign, I don't have Facebook but I'm sure you'll find them, around 5pm just before the zoo on the Doi Suthep Rd, many cyclist meet to ride up to the temple.
Found this interesting Christmas decoration from the 1800βs today in the ground while helping plant flowers at my local town hall. Itβs beautiful !!!!
I've one of the original Exciters, bought new about 7yrs ago, great bike, have used it for riding over to Utteradit from Chiang Mai many times, 90kph no problem, Rosso Sport tyres, stick to the road wet or dry.
