MB-1-E Part Seventeen: The Cargo Rack arrives

MB-1-E's picture

Hi All,

The new cargo rack arrived today.
It looks to be very solidly built and should transport the MB-1-E nicely.
Now I can load up the dogs, head for the backroads and get in some quality Electric Mountain Biking and the dogs can run along.

The receiver has some slop I need to fix ...
... so you're not imagining things if you see the rack sloping back

My handy-dandy DIY ramp

Securely hooks over the bar and gives me some traction

Currently, I'm waiting on some switches from Digikey.
As some of you know, I fried my switch that swaps me from Run (Series/Parallel) to Charge (Parallel only).
The switches that I ordered are rated at 30A at 125v.
They are a toggle type and as long as I don't switch them with any load, should work fine.
I got the last one off eBay and didn't really have any idea of the quality.
These should be at least as good at their rating ...
I hope.

I'll get some more pics of the MB-1-E when I get my switch on and the bike back on the road.

... Gilda Ratner was right ...
... It's always somethin'! :)

until then ...

Dave,

That is a nice ramp. I think it is a little too short for its intended usage. If you hit that ramp at 20 miles an hour you should get plenty of air but without suspension your landings are going to be a little rough. I think you should lower the ramp and maybe increase its length until you get good at jumping things.

Just my 2 cents,

also you should widen the cargo rack. I think at 20 mph you should be able to jump at least 8 dogs. From the pictures it looks like the cargo rack will only hold up to 4 dogs.

Has anyone else here done this?

In the second picture I see a chain link fence. If you are trying to jump that also I strongly suggest you wait until you have had some practice. If you almost make it but the rear tire catches on the fence it could put you into a somersault..

Pictures please, video would be better.

Hi Chuck,

As you can see from the second pic, I am getting ready to jump my fence there.
My dogs listen pretty well but I seriously doubt that I could get them to stand still and lined up there for more than about 3 nanoseconds.

Perhaps if I made a "rawhide chew bumper" for the truck they would stay there twice that long before they ripped the bumper off the truck and dragged it off into the yard.

On second though maybe I'll just use the ramp for loading purposes only ... :)

I, too, am interested in hearing about it if anyone else here has tried this. ;)

... not to worry, if I do make that jump I'll be sure to get the somersault on video so I can get royalties from them showing it on the "World's stupidest stunts". Maybe it will help defray some of the the medical bills.

I have awakened and looked into the eyes of a doctor. thank god they did'nt have video when I was a kid..

Seriously, though..
I went way back in your blog, I think it was chapter 4,, I see the closeup of your chain adjustment. If you use the same concept, only flip it over, in other words, have the attachment bolt higher than the barrel.. the force would be self straightening, the shear force would be on the bolt attaching the barrel to the bike frame,, that attachment point is chrome moly, very tough, also, for reasons beyond my knowledge,, allen head bolts withstand shear better than other bolts, it is a standard for that type of bolt in the tool industry,, I have never sheared an allen head bolt, even in the bicycle industry I have found the allen head bolt to be exceptionally tough and shear resistant.

I'll see if I can do just that Chuck.
I looked at the same photo just now and see exactly what you mean.
It also looks like the axle nut may act as a stop to keep the bracket from rotating back any farther.

I'll give it a try and let you know how it goes.

Thanks,

Dave
