A few days ago I just did the painting and final assembly on my Honda GX35 powered, front wheel drive bike. It uses a 1960s vintage Raleigh 20 folding frame. I built a flatbed cargo rack and removable sidewalls using locust wood (harder than oak), intended to allow my wife to haul two bags of groceries back from the local grocery store. The geared front wheel drive works great, and the bike works great as a normal bike with the motor off. This has been my goal with both of my motorized bikes. It uses an 18.75:1 gear reducer from David Staton (www.staton-inc.com), which is a little heavy at 8 pounds but should last forever based on the quality of construction. I've tried 18 and 22 tooth drive cogs on the gear reducer shaft and am not sure which to use in the long run. A test ride up a *very* steep and long hill allowed me to ascend at 9mph without pedaling the whole way on the 18 tooth cog. It seems to be a keeper as it rides very well and should be really functional with the cargo box.
