I came to adjust the switches, the master came out, took the bike, fiddled with it for 5 minutes, clicked something, then returned it to me with the words "You can take it, everything is fine." To my question, how much do I owe? He replied, "For the amount of work that I have done, it is not convenient for me to charge you money AND YOUR SMILE WILL BE ENOUGH for ME." That is, I had everything in order with the switches and the master turned out to be decent (which is very rare nowadays) By the way, the bike adjusted perfectly. The pavilion is also good both by choice and by price tag. Another time I bought wings, but I doubted if they would fit, since I was without a bike, the seller sold them, gave me a check and said that if they didn't fit, I could return them back or change them!
