I have heard of problems with the tranny and belt drive with both, but just want your guys' opinions. Obviously the Flying Horse kit is a little more appealing because its 50$ cheaper.

True both come with the same engine, but don't be tempted with the
$50 cheaper price.
Be warned that the Bikeberry kit has the old style Hoot gearbox on it.
There is no pic on Bikeberrys add of the "5G" gearbox.
The Grubee 4G is a MUCH superior gearbox to the Hoot although the
one from GasBike.net has the 4 to 1 gearbox with the problematic one
Buy the original 5 to 1 4G gearbox with the kit from Bicycle-Engines.com.
Here is what you actually get from Bikeberry as the "5G" kit
