Why don't we see more motorized bicycles that utilize a Honda Horizontal engine (Z50, XR50, CRF50, XL70, XR70, CL70, CT70,) etc.

These engines and their clones range in size from 49cc up to 150cc , are affordable, plentiful, and often have a built in 2, 3 or 4 speed transmission.

Just wonder why the 4 stroke bicycle builders don't choose this engine more often?

Is it simply the pedals interfere with the engine?

Your thoughts please!
 
I believe because with the transmission it makes your Motorized Bicycle illegal in most states requiring it to be registered as a motorcycle or moped.

That would be just too darn easy using those engines ;)
 
I strongly agree about looking like a ugly box (on its side)!
But they do have a history of being bullet-proof.
Plus its difficuly to tell a 49cc, from a 70cc, or 150cc for that matter.
Parts are abundant.
And the 2,3, 4, and 5 speed transmissions (manual and auto) are a plus, if not illegal.
They seen well suited for a stretch cruiser that has enough room in the frame to utilize this platform.
Im surprised we don't see more of them. ??
 
They are around. Easy enough to build one:

That one has a 50cc 3 speed auto clutch. It does 40 mph

We built one with the 125cc single speed auto clutch - it is actually faster with no shifting.

Electric start, power for lights. The single speed auto is California legal.
