Hi all. I'm new to forums. Good to be here. About me: One of my hobbies is riding and learning to wrench on a dual sport motorcycle. A Suzuki DR650SE to be exact. It's a great bike but that's not what I'm here to talk about. My father had a Whizzer when he was a kid. For 30 years he talked about wanting one when finally one day last year he bought one. A 1949 model. He found it on ebay for $1500. It had been nicely restored but never ridden or dialed in. We've broken it in and worked all the bugs out of it and it really is a surprisingly nice ride. It'll do 32mph with a 210 lb rider. Well, it now needs a riding buddy. We have an early 2000 Specialized Rock Hopper bicycle in near pristine condition. I want to make a modern version of the Whizzer with it. So far my internet searches have driven me to two conclusions. A CH80 with a jack shaft to take advantage of the gearing already there or a Honda GHX50 setup. No clue. I'm in over my head here. If you could point me in the right direction it would be much appreciated. Thanks all!
