Has anyone actually ordered one of these, can you comment on the
quality/completeness of the kit? It seems like a decent price, since
it seemingly includes all the handlebar controls, mounting parts, and a
No spam here. I am personally interested in such vehicles, and found
that site during one of my frequent searches. I posted the question to
this group, and this group alone, because as a longtime participant I
have read discussions indicating that we have quite a few guys with
experience motorizing a bicycle. These are the type of people likely
to have checked out the item for which I supplied a link.
In looking at the engine kit (did you check it out, or just give me a
knee-jerk reply?), I thought that it offered quite a bit for $160. For
example, the resurrected "Whizzer" company here in Dallas wants about
$700 for their engine kit.
The Whizzer components are manufactured in Taiwan. I assume this $160
kit is a Chinese knockoff of something, and I was genuinely hoping to
find someone who had been brave enough (or maybe lived near the
supplier) to check one out.
I imagine there are lots of applications. Many folks have a motorcycle
license, and registration/insurance for a moped is not expensive. On
the other hand, I can imagine scenarios where one would not bother,
such as using it to cruise the non-public streets of a large RV park,
etc. Of course, you could always pedal it anywhere (no license
required to carry an engine around as dead weight) and use the engine
for assist when you think violation risk is low.
I don't think the 50cc restriction is universal. For example, when I
was a kid in Tennessee, the dividing line between "motorcycle" and
"motor-driven cycle" was 5 HP, regardless of displacement. We all rode
90cc Honda motorcycles when we were 14 (moped legal age), thanks to an
enterprising dealer who installed (easily-altered) throttle blocks
above the carburetor slides and certified them as 5 HP.
Thanks for the links. From the reviews, it appears that there may be
some issue with piston galling and seizures. Maybe the chinese aren't
that careful what metals they allow to rub together. I note that the
ebay seller offers complete replacement engines for $80, though. What
Much of this galling problem has to to do with two lubrication problems
as opposed to quality problems.
Some people use the wrong oil, and most people make the mistake of using
the manufactures recommended ratios. These ratios are intentionally
weaned out to satisfy the environmentalist. After cooking a brand new
leaf blower with 40 to 1, I switched to 16 to 1 (or 20 to 1) on
everything,across the board, old or new. 5 years later and I have not
had any problems with string trimmers, leaf blowers, and chainsaws.
The oil I use is called Opti-Lube or some thing like that. It has Opti
as the first part of the name. When used according to the package
directions the mix ratio is about 100 to 1. It works very well. I use
it in all my 2 stroke motors. Chain saw, outboard, etc.. I called the
company when using it for the first time several years ago and spoke
to the company president. He told me that he collects antique
outboards and he uses the oil at 100 to 1 in the old motors. They will
replace any motor that fails from lack of lube, such as galling or
bearing failure, free of charge. It's more expensive by volume but
about the same by use as other oils. The motors run much better with
the leaner mixture and plugs foul much less. Here is the web site:
. I have no connection with any company making
or selling this stuff. It just works very well.
In addition to the other comments, I wonder about the sprocket sizes.
The rear sprocket is small enough that I doubt this could be
direct-drive off the crankshaft, yet there is no mention of a
transmission. I wonder if it just has a simple on-board gear

In the picture, there is a big lump on the rear (right in
picture) of the crankcase. There is no reason for that on a
2-smoke without gear reduction, so that's probably the
internal gear reduction. Probably also acentrifical clutch
like the 60cc engine below it.
3.5 hp is real dismal power for an 80cc 2-smoke, so it's
probably also a low speed engine for an 80cc. Even a not
too well designed 80cc 2 smoke shold be able to develop 3.5
hp at about 4,000 rpm.
Mart> In addition to the other comments, I wonder about the sprocket sizes.
Don't you just love the "plain-english" descriptions? The kit is made
in China, but supposedly the dealer is in Missouri. So, does this 60cc
kit have a clutch lever? And is he saying that you'll have to come up
with your own, wider, crankshaft?
from the web site:
It is an Automatic bicycle motor, It does not have a clutch lever. It
has a centrifugal clutch when throttle handle is turned and rpm begins
and you go just like a gas scooter. New improved bearings, wider cranks
will be needed. Gets around 150 miles on a gallon of gas. With this kit
you can convert an ordinary bicycle into a gas powered bike. Operates
like a moped. You can pedal the bike or start the engine by releasing
the clutch lever.
Clear as mud, eh?

Don't you mean "when you think getting _caught_ risk is low."?
