Many know of the late Sheldon Brown. He was an avid cyclist who was also a very knowledgeable and highly respected mechanic. BTW, he was also a tadpole trike rider. Here is a picture of him seated on his Greenspeed trike.
His web site continues on today years past his departure from us. One of the web pages is titled “Tricycles … not only for kids”. You can check it out by clicking HERE.
