I got into this hobby business right before Katrina caused prices to skyrocket by 75 cents or more. Those prices have been fluctuating, but the only constant is profits for the oil companies. Well, on NBC tonight (March 30) they reported San Francisco prices bumping $4, with more to come. Over 5,000 miles traveled, I have tried to tell folks that simple things like bike engines would SOLVE this shortage, if able and patriotic Americans would physically get in the saddle. So, if you are shopping, need installation help with GEBE engines, I'll be happy to make the thing run right. My only rule of thumb is heavier riders need the bigger engine, slim in-shape folks (like myself) can keep up with the pace. (snark) I found a $250 Cruiser bike from Sun that fits nearly every need, and if you add a few modifications, you can make it reliable and comfortable. I just hope, if you choose Sun or GEBE you mention that you heard it on MB.com, the best forum for getting the right answers (eventually) Things get hectic in the summer, checking on the forum is a priority, but bikes and engines can be addressed simply, post any question, do a little reading, and together we can find the best answers.
