This is the review I posted on their website about the Zeda 80...very impressed...works flawlessly...DAMIEN
"Very impressive, Zeda 80 black engine kit.
I have previously bought both Flying Horse and Seeutek kits from major competitor before I even heard of Bicycle Engines.com...This Zeda 80 just blows them all right out of the water.
It is simply put, a much better designed engine with much more power than the two i just mentioned.
Quality is sooooo much better with improved power and top end speed.
I ordered it with the 36 tooth sprocket which was also a MAJOR improvement for off the line acceleration as well as top end speeds, I had previously used both the 48 and 44 tooth sprockets on previous builds.
For what it is worth, I used to be an ASE certified master mechanic/technician until my retirement 10 years ago.
Special shout out to the two fine ladies i talked to, first one when i ordered the kit over the phone, and also when i had one minor problem when the accelerator twist grip wasnt quite right, they replaced it via mail within just a few days no charge.
Cannot tell you how happy i am with my purchase with Bicycle-engines.com, The kit was delivered to me in Alamogordo NM from their Montana location within one week.
THIS IS THE ONLY entity I will order from for now on".
Ps...Also had a gas cap that was too tight a fit on the gas tank and the rubber gasket split on third fill up about a month after i got it...they didnt just replace the cap, but the entire gas tank system as well within three days at no charge, they did not even require pics as proof or return of old one.
As a side point, without any extra modifications, This bike weighing in at 80 pounds went up to 47 MPH and i still had throttle left...I only did it once since i have no desire to go that fast on a bicycle, and no desire to clean the racing stripes out of my underwear at 65 years of age, just wanted to see what she could do...lol.
