Those guidelines only apply to commercial interest and not to custom makers
otherwise you weld it it has to be certified! and even in commercial
it's only about every 10th part checked, if not 100th part
do you know how many Idiots have been killed by commercially produced
atv's?
it's not anybodies fault if the user is an idiot!!! jumping a bicycle at 40 miles
an hour and they wonder why their frames crack? ROFLMAO

and then they do something idiotic IMHO
I'm sorry if this sounds insensitive, but what do you call someone
who's taping 1 and 1/2 sticks of dynamite to their ass** and hitting it
with a hammer
1 gallon= 3 sticks of dynamite
Your bike frame can crack just as easily if a 300 lb. fat azz climbs on a bike than if a 170 lb. rider climbs on a motorized bike. The fat azz is putting more stress on the frame than any 20 lb motor ever would.
Yet there are no NHTSA regulations against a fat azz hopping on a bike. LOL
Look at the FMVSS regulations regarding Mopeds and Motor Driven Cycles. You could make a frame out of Bamboo if you wanted to. You would eventually be sued into the ground when it fails, but NHSTA has specific no regulation against it.
FMVSS and regulations that apply to "On-Road use only" motorcycles, mopeds or motor driven cycles, including three wheeled vehicles are as follows:
1. FMVSS No. 106, Brake Hoses
2. FMVSS No. 108, Lamps, Reflective Devices, and Associated Equipment
3. FMVSS No. 111, Rearview Mirrors
4. FMVSS No. 116, Motor Vehicle Brake Fluids
5. FMVSS No. 119, New Pneumatic Tires for Vehicles Other Than Passenger Cars
6. FMVSS No. 120, Tire Selection and Rims for Vehicles Other Than Passenger Cars
7. FMVSS No. 122, Motorcycle Brake System
8. FMVSS No. 123, Motorcycle Controls and Displays
9. FMVSS No. 205, Glazing Materials
