I would have to say the strangest thing I've ever seen in my LBS is something that can only be described as an abomination. Try to picture this as I describe it ok?

I saw a Huffy mtn bike with a weed trimmer motor attached to it. A gas powered one, not electric.

Rider position: This thing had foot pegs attached to conventional axle nuts in place of the QR at the rear so the rider could put his legs back so they would not get in the way of the motor & not be burned by the hot exhaust. Imagine the crotch rocket position.

Motor support: The motor was sitting on a steel plate that was welded to the top tube with a support brace welded to the bottom of the plate & to the angled down tube near where it meets the bottom bracket shell.

Drive train: The bottom of the motor was even with the top of the top tube to the right of it with the exhaust blowing across to the left. This thing had a longer shaft on it that went across & above the top tube. The shaft had a sprocket welded to it with a chain that went down to the chain ring.

Because of all the extra heavy weight of this thing the genius that built this contraption drilled holes in the top tube & down tube to lighten it.

Now anyone with half a brain would not in his or her right mind build such a death trap. First of all there are not guards around the chain that goes from the motor to the chain ring. Plus nothing to deflect the hot exhaust blowing across the top tube. Plus the center of gravity on this thing is totally changed & differant because the motor is up high & on the one side.

Does anyone else see the problems or potential for serious injury & worse with the thing?

Oh & the reason it was at the LBS. The guy needed a new chain to go from the sprocket attached to the motor down to the chain ring. Unfortunatly the shop did the work for this guy. IMO they should not have because of liability reasons. By that I mean this bike has been seriously altered & this is not an intended purpose for a bicycle with these types of alterations. So if something happens to anyone who rides it the shop could potentially be held liable for putting the new chain on.
