Motorized Bicycle DIY: The hard way

Step 4: Semi-Finals

Here she is - Nearly complete (or so I thought a the time).

24" Huffy Boy's Cranbrook.
Honda GXH50 engine
EZ Q-Matic drive system.

The sprocket pictured here is the still the original "rag-joint" sprocket.

IT"S A GONNER!

The next step is to replace it with an HD hub/sprocket kit that attaches directly to the hub - NOT the spokes (like a rag-joint)

Yes, it requires a total rebuild of your rear wheel (it's called "Re-Lacing")
And, as I found out - the rear forks would have to be widened by 0.50" on each side. (quite a stretch for a 24" bike)
I spent quite a bit of time investigating the local bike shops in my area and found that most of them were pretty leery of the "Dishing" that is required on this type of hub.
Luckily, I found an excellent bike shop in my area did that did for me for around $50.
The "Dishing" required on this type of fat tire hub is quite surprising - and quite an education in itself.
It's worth the extra bux... (please! don't even waste your time with a rag-joint!)
