It happens to us and it really sucks that someone steals the bike. I had 6,000 miles on my bike which I think I have pictures here of. Thanks to my brother Tom I will have the money to construct a new bike. I have some overhead to take out of the monies but I am looking at at least $1500 to work with. It should get me started. I am sure after all the accessories I had I was closer to $3k invested than $2k but that is how it goes. The up side is I could have completed the cleaning and the maintenance of the bike before it was stolen but I was lazy. It is out there without a chain tensioner and I hope with the chain so slack it locks up at high speed. So this time out I think I will work smart. I want you to suggest things please. I am out of the loop. Here is what I do. I ride 40 minutes each way to work at about 25 mph and I use my bile to do all my "driving" It is my car. So it has to be able to go good. I know of Jack-Shaft and I know it can be a problem from what people say. The Idea would be a 4-stroke and even jack-shaft if it can be done right and will last. I would be buying all new and can do a 2-stroke again so that is cool. What do you suggest? 4-stroke what motor? What engine mount? Jack-shaft the key here is the most dependable and easy to repair. I ride long stretches in the country so I can be easy on it and speed would be best if keep it under 35 but to be able to gear down for a hill is very attractive if I have a 4-stroke. So any suggestions on good but affordable frame, The engine if 4-stroke should last so which one? To Jack-shaft or not? I know I need heavy duty wheels and I will want disc breaks. The first then is the power train. Okay.. As you may guess I am still shaken to have my bike stolen from my yard in the middle of the day. I am taking steps to change that. Thanks for you help. This is a Bike emergency. P.S. We need some animation that shows a guy seeing his bike is stolen.
