I am not competing just posting

It is getting too hot.
I really enjoy my Happytime.
I would like something that does not buzzz so much.

I found goped nation Ehhhh!!!

I also found an $42.00 plus 15.00 shipping total cost mod that attaches a continuously variable transmission. to a small engine.

I am planning on building a rack mounted friction drive or a chain drive version with a 62 tooth rear sprocket.


The friction drive version would be a complete backend off a go ped with the cvt mod , using a solid rubber convex drive wheel.
Quite possibly NO slippage with an automatic transmission.
The chain drive version is a 10 tooth output gear with some BMX chain and a 62 tooth rag mounted rear sprocket from andyinchville's sprocket sales.


This engine a honda 50

With this CVT


This one is inexpensive

This one is $80.00

With this design

I will be busy this summer.


Way after it is broken in I want to try this

HHO Gas Mod - yay or nay?

I zip all over town just like the gas prices were not so high, why not I only pay $8.00 for gasoline per month.
I have had people get mad at me when I tell them how much I spend on gas per month.

Wait till my average gas price goes to $2.00 per month.


My happy time cost four fill-up's.
About a months worth of gasoline for an average car. LOL!


Add another Rackee to the tally.

If I didn't already have the scooter rear wheel with sprocket, i would have gone with the goped engine and wheel myself I think. I am convinced friction drive is less trouble than the chain wheel puller.

I have tried the chain friction wheel with electric which is about the same rpm and it works just fine. I am expecting my weedeater conversion to work easily. If not I might look for a different drive mechanism. With friction drive the engine can be less powerful since it doesn't have the dead weight of the bike to pull around. If it gets too much the wheel just skips over the bike wheel.

the other alternative is the smaller Izip rear wheel with the belt drive to just attach the belt drive pulley to the weed eater (in my case).

I just realized that my 43 dollar cvt will fit on a happytime.
As a frame mount engine with a rack mount CVT transmission. LOL!
Chain driven apologies , and kudos to Deacon ( it could just as easily become a friction drive with a bmx foot peg and some jbweld N sand smeared on the footpeg).
Slow build as my garage is not airconditioned.

wait...so you will have your HT frame mounted with a chain going to the cvt on the rack and then down to the sprocket?

Honestly, that would be genius.

So what size spur gear did you use on the shaft of the motor? How about the sproket on the wheel? Send any pictures if you have any to share, I would like to do something like that for a project down the road.........

I am sorry that I did not answer sooner. I simply am out riding .
I used the ten tooth drive sprocket that came with the kit.
I welded a ten tooth sprocket from a local supplier to the input of the cvt.
As well as a ten tooth output from the cvt not the reduction portion of the cvt. To the 44 tooth rear wheel.
My modified cvt has a 2 to 1 reduction to a 1 to 1.6 gain
for a 44 tooth rear wheel sprocket approximately 88 tooth to start. then a 30 tooth at top end.

I take off like gangbusters then all to soon push it home.
I am still breaking too many parts.
Still working on the weaknesses.

Sounds like a work in progress. Great idea though, if possblie post some pictures of the set-up when your ride becomes relaible!!

I HAVE ALWAYS ENJOYED MEETING NEW GUYS IN TOWN WITH MOTORBIKE INTERESTS.
(I do NOT enjoy the cap lock button) One fellow from Enid Ok. told me and later showed me their method. They take the field housing off a car generator and replace it with pieces of pipe on the bolts. It is mounted behind the seatpost by the mounting hole on the castings and the motor is mounted on the rear carrier. The armature rotates on the rear wheel held there with a spring and clutched by pulling it up. The belt is tight when in contact with the tire. FWIW

It looks like that CVT unit, well torque converter actually, will bolt right on to say a Robin eho 35? Say it ain't so!!! Also the way it is mounted on the goped it looks like it reverses the rotational direction of the motor? Enquiring minds want to know! Thanks in advance, Hitekrdnk

I solved it!
Do not order random parts.
On another channel I begged .
On goped nation I begged.
Without help I solved it.
One engine.
One cvt.
Rack Mount only A Happy Time is too powerful , Too close. LOL!!!
Thank God I still have my left Leg.
A bmx chain will fail.

Do Not order random parts
SOON I will Post Pictures.

I have two found two competing designs.
One A CHAIN DRIVE CHEAP but strong Very STRONG! !! No CVT
One a cvt Cheap But with a weakness====== the belt in a cvt.
